Speaking Science: Inspiring Interest in Academic Research

University researchers are constantly pushing the limits of knowledge in their fields, making discoveries that stand to change how people think and the way they live. For research to inform the decisions people make, however, they must first be able to understand it.

Earlier this month, the University of Minnesota hosted the latest conference in a series designed to help scientists more effectively share their knowledge and research with audiences outside of academia. “Speaking Science: Communicating with Media, Funders, Policymakers, and the Public” brought together faculty, postdoctoral researchers, and graduate students interested in honing their communications and storytelling skills.

The one-day event, hosted by a collection of colleges and units from across the University, featured interactive training exercises, breakout sessions, and a keynote presentation by award-winning scientist Hope Jahren, PhD, who detailed her paleobiology career to date in the national bestselling memoir Lab Girl .

Making Them Care

While it’s tempting to think that data alone will change the way people think and behave, often it takes a little bit more—the audience needs to care.

In “The Science of What Makes People Care,” University of Florida Center for Public Interest Communications experts Ellen Nodine and Matt Sheehan distilled principles from behavioral, cognitive, and social science into six guidelines that scientists can use to help get people to care about their work and what it means.

Among these principles was shaping the communications approach to fit the audience scientists aim to reach. By understanding the values and identity of these individuals or groups of people, Sheehan said, scientists can approach them from a familiar standpoint and better connect and communicate with them. This step can help avoid “solution aversion,” where people dismiss an idea because it goes against their worldview or makes them uncomfortable.

“Effective communication is no longer about just pushing your message,” Sheehan said. “We need to find where our values intersect.”

Another important lesson was to “talk in pictures.” This includes employing actual photographs and visuals, but also written and spoken language that helps the audience picture an environment or an action in their mind. Nodine and Sheehan suggest painting a more vibrant picture using imagery like “sit down together at a table” and “join hands” to deliver a more memorable point to the audience than by speaking in abstraction.

“We remember material far better when it’s expressed in concrete language that allows people to make more visual images,” Nodine said. “What kinds of images and metaphors can you use to help people understand and connect with your ideas?”

In addition to using imagery, a message will make more of an impact when it draws on emotion. Nodine and Sheehan suggest considering how intentional use of emotions like anger, humor, and sadness can amplify the message. They also suggest considering how less commonly used emotions could factor in. What role can hope, pride, or awe play?

When it comes to the message itself, cut back on field-specific jargon and instead define just the key terms and concepts the audience needs to know. Think also about what you want the audience to take away from your message. Is there a call to action? If so, give them a specific action relevant to their lives that they can take, and then show how their participation will support a larger goal.

Finally, remember to tell stories. Think about how exposition, characters, conflict, and resolution can help connect people to the meaning behind the facts and data.

“Our societies are built on the stories that we tell ourselves,” Sheehan said. “We are uniquely wired to respond to stories, not to facts.”

The Art of a Likable Science Talk

When it comes time to present your research, will people stay tuned in? Will they like it? As Hope Jahren told attendees during her keynote presentation, these questions matter.

“A good talk can make or break a career,” said Jahren, who got her bachelor’s degree at UMN Twin Cities and is currently a professor at Norway’s University of Oslo. “This is our oral tradition. It is the talks that we give, not the papers we write, that really let us share who we are and what we do.”

To discover how to give a scientific talk that people will like, Jahren and her team studied the composition of dozens of scientific talks, recording data about the length of the presentation, what worked well, and what didn’t. While the concept of “liking” something is inherently subjective, several researchers evaluated each talk to ensure no individual bias swayed the numbers. The team also tallied the types of slides used to gain a clearer picture as to exactly how presenters were conveying their information: text, photos, maps, graphs, tables, equations, or videos.

What Jahren and her team found was that there’s no clear “recipe” for how many of each type of slide presenters should use to achieve a likable talk. Some excellent talks were heavy on photos, while others used lots of graphs. There was, however, a consistent length for good presentations—one that has become a “contract” of sorts between the speaker and the audience—which averages to three quarters of an hour long, with about 33 slides total and just over one minute spent on each slide.

Jahren’s study also found that people generally want to like a scientific talk when they hear one, giving the presenter the benefit of the doubt, though she noted that this could vary based on the culture, the specific academic discipline, or the particular individuals in the audience.

At the end of a scientific talk, Jahren said it’s important to remember to thank the audience for choosing to spend their time listening to and discussing scientific ideas.

“We should all feel good about what we just accomplished,” she said. “We learned and we shared and we came together as people who are all interested in the same thing. And that in itself is a wonderful, wonderful way to spend the day.”

Center and Institutes/Laboratories

Acquired Brain Injury Communication and Cognition (ABC) Lab

The Acquired Brain Injury Communication and Cognition (ABC) Lab studies the behavioral and neural factors that support the recovery of language and cognition in people who have aphasia and/or a traumatic brain injury. The lab conducts both basic and applied research studies with the goal of developing interventions for language comprehension and cognition.

Arianna LaCroix

Lab Website

Attention and Neurodevelopmental Disorders (AtteND) Lab

The Attention and Neurodevelopmental Disorders Lab investigates attentional strengths and weaknesses in individuals who are at risk for or diagnosed with autism spectrum disorder (ASD) to identify new targets for intervention as well as improve current intervention strategies. This research provides insight into how attention affects the development of social and communicative abilities in typically developing children and children with ASD.

Brandon Keehn

Aphasia Research Laboratory

The Aphasia Research Laboratory focuses on how language processing is affected by aging and acquired neurological conditions (stroke, Parkinson’s disease) and identifies the factors that facilitate language recovery in individuals with aphasia. The findings provide insight into how language is stored and processed in the brain and aid in the development of intervention approaches for people with aphasia.

Auditory Cognitive Neuroscience Laboratory

When listening to speech in a noisy public place, most adults find it easier to understand the speaker if they can see the person’s face because facial movements can provide a great deal of information about speech content. However, this ability to use visual speech cues when the sound quality is poor is not present at birth and develops gradually in children. To better understand this, the Auditory Cognitive Neuroscience Laboratory studies how and when children learn to use visual speech information and how their language development may be negatively affected if they fail to acquire this skill. We work with typically developing children and also with children who had delayed language acquisition.

Natalya Kaganovich

Auditory Electrophysiology Laboratory

The Auditory Electrophysiology Laboratory uses electrophysiological measures to understand the neural representation of complex sounds in normal and impaired ears at the brainstem and cortical levels and how these representations are shaped by experience. The long-term objective is to enhance the encoding of behaviorally relevant dimensions of sounds and determine their relative roles in the temporal structure of sound. We are also interested in evaluating the nature of the interplay between early sensory level processes and later cognitive levels of processing.

Ravi Krishnan

Auditory Neurophysiology and Modeling Lab

Research in the Auditory Neurophysiology and Modeling Laboratory involves the coordinated use of neurophysiology, psychoacoustics and computational modeling. This multidisciplinary approach provides a powerful framework to enhance our understanding of the effects of different types of sensorineural hearing loss on neural and perceptual responses to sound. This knowledge will be extremely valuable for developing diagnostic tests, evaluating the limitations of current hearing aids and suggesting novel strategies for hearing aids and cochlear implants.

Brain Research in Auditory Neuroscience (BRAiN) Lab

The BRAiN Lab investigates auditory perception and speech processing in adults with cochlear implants. The goal of this research is to better understand the individual differences in auditory perception that impact speech-recognition outcomes in cochlear implant recipients.

Maureen Shader

Child Language Research Laboratory

In the Child Language Research Laboratory, we study how children learn to produce and understand words and sentences. We are especially interested in discovering the reasons behind why children with language impairments experience difficulties — and finding ways to help these children overcome their language learning problems. Our studies also include children who are developing language without difficulty, so we can have a clear idea of the learning patterns associated with typical development.

Laurence B. Leonard

Child Phonology Laboratory

Research in the Child Phonology Laboratory investigates how monolingual and bilingual children learn to produce speech sounds with the goal of developing best practices for assessing and treating children with phonological disorders. In particular, we are interested in better understanding how the ability to perceive speech sounds affects the accurate production of speech.

Françoise Brosseau-Lapré

Cranial Sensorimotor Control and Neurodegeneration Lab – Schaser Research Group

The Schaser Research Group uses advanced imaging tools and an alpha-synuclein fibril seeding approach to study protein aggregation in a mouse model of Parkinson’s disease and Dementia with Lewy Bodies. We specialize in merging clinical issues, animal behavior, and exploration of pathology in the cranial sensorimotor system to characterize and treat voice, communication, and swallowing deficits related to neurodegeneration.

Allison Schaser

In the Purdue I-EaT Lab, we investigate the underlying mechanisms that control swallowing function and eating in adults and children with and without swallowing disorders (dysphagia). The primary studies involve patients with cerebral palsy, stroke and Parkinson’s disease. We aim to use this knowledge to develop and evaluate novel rehabilitative treatments that will be effective, accessible and adhered to by patients to improve their health and quality of life.

Georgia Malandraki

Language Learning and Meaning Acquisition (LLAMA) Lab

Because children have an exceptional ability to learn language, the LLAMA Lab explores the cognitive mechanisms that support this ability. Ongoing research topics include how children understand connections between word meanings, how general learning mechanisms and experience support speech comprehension and early markers of risk for poor language and reading outcomes.

Arielle Borovsky

Motor Speech Lab

The Motor Speech Lab covers a wide range of topics related to quality of life for older adults and individuals with Parkinson’s disease in an effort to treat the changes to speech and cognition that occur as a part of typical aging or as a result of aging-related diseases, such as Parkinson’s disease.

Psychoacoustics Lab

Research in the Psychoacoustics Lab focuses on behavioral measures of peripheral auditory processes in listeners with normal hearing and listeners with cochlear hearing impairment. We are particularly interested in studying dynamic adjustments in response to background noise and use models of auditory signal processing to connect behavior and physiology.

Elizabeth Strickland

Purdue Experimental Amplification Research (EAR) Lab

Research in the Experimental Amplification Research (EAR) Laboratory focuses on auditory processes that contribute to speech perception deficiencies in hearing-impaired listeners and hearing aid processing. Ongoing projects include work on frequency-lowering techniques, wide dynamic range compression and speech enhancement techniques.

Josh Alexander

Purdue Infant Speech Lab

The Purdue Infant Speech Lab explores how language comes to the child by focusing on whether measures of early speech perception, production and the input relate to later language in both typical development and in children at-risk for autism spectrum disorders.

Speech Perception and Cognitive Effort (SPACE) Lab

The Speech Perception and Cognitive Effort Lab focuses on the contribution of cognitive mechanisms — such as working memory and selective attention — to understanding speech in difficult circumstances. For example, this could include a talker with an unfamiliar accent or the presence of competing sounds. We use behavioral and psychophysiological measures to assess speech understanding, cognitive effort and stress in younger and older adults (with and without hearing impairment) under a range of listening conditions. Results of this research provide insight into the cognitive foundations of spoken language understanding and contribute to improving methods for the assessment and treatment of hearing impairment in older listeners.

Alex Francis

Sign Language Research Lab

Research in the Sign Language Research Lab uses theoretical and experimental methods to investigate aspects of sign languages and their similarities and differences to spoken languages. Results from this research are applied to improving deaf education and the quality of life of members of the deaf community. Projects include experimental studies of sign language structure, perception and production. Our work incorporates online questionnaires, psycholinguistic methods, motion capture analysis and neurolinguistics, as well as collaboration with engineers toward automatic recognition of sign language.

Ronnie Wilbur

Voice Lab — Sivasankar Research Group

The goal of the Sivasankar Research Group is to understand why some speakers experience voice disruptions related to prolonged speaking, aging, environmental exposures and disease. We utilize a multidisciplinary approach to understand the causes of voice problems in order to better prevent and treat this common communication disorder.

The School of Audiology and Speech Sciences at UBC owes its reputation for excellence in research to the outstanding research programs of faculty members . SASS faculty are engaged in research in all areas of human communication and its disorders.

Student Involvement in Research

At SASS, student involvement in research is a crucial aspect of education. Graduate students and postdoctoral fellows are valued as key members of SASS research teams. The School’s faculty believe that educating independent, successful researchers requires providing not only strong guidance, but also enough freedom for student researchers to explore uncharted territory, and to discover new knowledge.

Research Settings and Partnerships

Research is conducted both in well-equipped university laboratories, and in clinical settings in the community. The School’s relationships with numerous clinical faculty members — located in schools, health units, private practices and hospitals across Canada — allow faculty members and students to work at the forefront of the field, implementing innovative, research-based solutions in clinical settings. Given the interdisciplinary and inter-professional nature of some of the School’s work, faculty members and students also collaborate with academics from other disciplines (e.g. linguistics, nursing, otolaryngology, psychology, and social work).

The School’s research activities are well supported by a variety of competitive private and public sources, including Tri-Council funding. Faculty members’ research findings are disseminated in a wide variety of forms to many different audiences, including academic, professional, and public audiences.

Business Speech: Types with Examples, Informative, Special, Persuasive

business speech

Good presentation and speaking habits may be considered soft skills in the workplace or in any type of organization. Today in this article, we have shared what is business speech and how many types of business speeches are there.

Anybody can relate to all these types of business speech because these all are equally important in social life as well. So let’s start our topic with the basics of business speech.

► What is Business Speech?

Speech refers to that action when a person stands among a great number of people and starts delivering any kind of information or statement. It may be or may not be useful for the whole audience but most of the time it is valuable for them.

A speech that is delivered in the workplace or in any business organization for some specific purpose is known as Business Speech.

This is one of the forms of Business Communication and the audience has to sit quietly while the speech is being delivered. Most of the time audience knows very well that the speech must contain anything that will be beneficial for them.

► Types of Business Speech:

types of business speech

There are mainly three types of speech that are as follow;

  • Informative Speech
  • Persuasive Speech
  • Special Occasion Speech

◉ Informative Speech

Informative business speech can be defined as speech that comprises the purpose to deliver useful information to the audience.

For Example  – In any organization, an Executive Coach or Trainer speaking about the new trends in the market to his trainees. It can be hard to understand for few trainees, but the fact is that he is delivering something informative that is beneficial for them.

Informative Speech is further divided into four types;

  • Speeches about Objects
  • Speeches about Events
  • Speeches about Processes
  • Speeches about Concepts

The following are known kinds of informative speech.

✔ Speeches about Objects :

It can be about any object related to that particular organization where the speech is being delivered.

For Example  – how various wildlife animals look, what is the smell of medicine, information about any product.

✔ Speeches about Events :

Those speeches that inform the audience about any events like historical incidents or about any situations are called speeches about the event.

For Example  – New President’s speech about future goals after the oath-taking ceremony.

✔ Speeches about Processes :

The main purpose of this type of informative speech is to inform the audience about anything which is currently happening or about how to do any particular task or work.

For Example  – a Yoga teacher explaining how to perform specific yoga poses.

✔ Speeches about Concepts :

Speeches about concepts are those speeches that inform the audience about any concept such as the peace of the world, freedom of rights, or love, fundamentals of any study topic.

For Example – a Science teacher explains Einstein’s theory of general relativity to his students in the class.

◉ Persuasive Speech

Persuasive Speech refers to those speeches where the intention of the speech is to convince the audience to accept the particular opinion or fact and create influence on the audience to do anyhow.

In short, the speech which influences the listeners or audience to follow a certain idea is called a persuasive speech.

Persuasive speech is also an informative speech. because here speaker gives information in a lucrative manner to influence others.

For Example  –  in any debate, every person is try to persuade others to follow their given point of view. It is a form of persuasive speech.

In another example, During the advertising and promotional functions of any business, the sales manager or speaker uses his persuasion skills to influence the audience. Here the main purpose of speech is to change the thinking, beliefs, or behaviors of the audience towards his product.

Persuasive speech can be divided into three types that are as follows:

  • Factual Persuasive Speech
  • Value Persuasive Speech
  • Policy Persuasive Speech

✔ Factual Persuasive Speech:

The Factual Persuasive Speech is such a speech that contains facts and it is based on a concrete proof about the certainty of anything that had happened.

The main purpose of this factual persuasive speech is to persuade the listeners whether the certain thing happened or not, exists or doesn’t exist.

For Example – If a student is giving a speech about the first man, who landed on the surface of the Moon. Nobody in the class knows whether it did happen or not, yet it possesses concrete proof.

✔ Value Persuasive Speech:

A Value Persuasive Speech is such a speech that tells the listeners about anything, whether it is wrong or right. The purpose of this speech is to challenge the ethical or moral aspects of a certain issue.

For Example –  If someone is giving a speech about capital punishment, whether it is moral or immoral, right or wrong, done or prevented. this type of speech is a value persuasive speech.

✔ Policy Persuasive Speech:

The policy persuasive speech refers to that speech where the speaker is trying to persuade the audience to either following a policy or rejecting it. It is not limited to just a policy, but it can be about accepting or rejecting a rule or a candidate is also a policy persuasive speech.

For Example – Suppose If the President of a country is not satisfied with the present foreign policy and wants to change it. The president gives a speech to higher authorities for convincing them to change the current foreign policy and support the new policy then it is known as policy persuasive speech.

◉ Special Occasion Speech:

Special Occasion speech refers to that speech which is given on the special occasion like;  A speech of farewell allows someone to say good-bye to one part of his or her life as he or she is moving on to the next part of life. Maybe you’ve accepted a new job and are leaving your current job.

Special occasion business speech is something which anyone can face at some point in their lives.

For example –  If your company won an award of the year for excellence. And you are receiving that award on the behalf of your company. The speech given by you after getting the award can be considered as a special occasion business speech.

In another example, If you are getting retirement from your job and want to thank your subordinates, superiors, and top management at the farewell party.

Associated Data

Clinicians depend on the accuracy of research in the speech, language, and hearing sciences to improve assessment and treatment of patients with communication disorders. Although this work has contributed to great advances in clinical care, common statistical misconceptions remain, which deserve closer inspection in the field. Challenges in applying and interpreting traditional statistical methods with behavioral data from humans have led to difficulties with replication and reproducibility in other allied scientific fields, including psychology and medicine. The importance of research in our fields of study for advancing science and clinical care for our patients means that the choices of statistical methods can have far-reaching, real-world implications.

The goal of this article is to provide an overview of fundamental statistical concepts and methods that are used in the speech, language, and hearing sciences.

We reintroduce basic statistical terms such as the p value and effect size, as well as recommended procedures for model selection and multiple comparisons.

Conclusions

Research in the speech, language, and hearing sciences can have a profound positive impact on the lives of individuals with communication disorders, but the validity of scientific findings in our fields is enhanced when data are analyzed using sound statistical methods. Misunderstanding or misinterpretation of basic statistical principles may erode public trust in research findings. Recommendations for practices that can help minimize the likelihood of errors in statistical inference are provided.

Statistical techniques are not magical or mysterious; rather, they are tools designed to quantify scientific evidence in various ways. Each method is built upon a mathematical foundation and has well-defined appropriate uses and requirements. Understanding more about these foundations, as well as the assumptions made by statistical procedures, can help investigators to adopt the most appropriate statistical method for the problem at hand, leading to more reliable and replicable results. Most traditional statistical methods follow the frequentist philosophy, in which models are fit via maximum likelihood or ordinary least squares. There are, of course, alternate perspectives on statistical inference, including Bayesian statistics and algorithmic modeling/machine learning. In addition, there are many techniques in nonparametric inference and variations on likelihoods (e.g., partial likelihood, semipartial likelihood, quasilikelihood, pseudolikelihood). Our focus in this article, however, is primarily on frequentist hypothesis testing using maximum likelihood, which is at the core of most applied science, as well as introductory statistics curricula. We expect that readers of this article have had at least one basic course in statistics. Researchers in speech, language, and hearing sciences are used to designing studies to learn about specific topics of interest, and many do perform their own statistical analyses to answer their hypothesis questions. Therefore, our goal is not to review all of the basics of statistics; rather, our goal is to highlight common errors and misconceptions in statistical approaches that can help scientists to avoid common statistical pitfalls in their research. In a companion article, some advanced methods for analyzing data in speech, language, and hearing sciences will be highlighted ( Oleson, Brown, & McCreery, 2019 ).

The use of statistical methods with underlying assumptions that do not match the data can have potentially serious consequences for the accuracy and reproducibility of scientific results. A recent analysis in major behavioral psychology journals indicated that approximately half of articles published between 1985 and 2013 contained at least one statistical error, and around 12% of published articles contained a statistical error that would have altered key findings of the study ( Nuijten, Hartgerink, van Assen, Epskamp, & Wicherts, 2016 ). Widespread findings of errors in statistical reporting and interpretation are believed to have contributed to an inability to replicate key scientific findings from the literature in psychology ( Pashler & Wagenmakers, 2012 ) and medicine ( J. P. Loannidis, 2005 ). Problems with replication of statistical results erode public trust in science and can reduce the impact of scientific findings. Fortunately, many current problems related to the lack of transparency and reproducibility in scientific research can be resolved through increasing statistical proficiency of scientists and promoting open and transparent practices in the sharing of the code used for statistical analyses and data ( Peng, 2015 ). To be clear, clinical and scientific experts do not need to become statistical experts, but they should recognize the statistical principles involved in their study design and their statistical analysis plan. Moreover, they should seek out collaborations with statistical experts to be involved with the study design and the statistical analyses. Study teams should include statistical expertise early in the development process to help design the study, to set up a clear and appropriate analysis plan, and to ensure appropriately analyzed and presented results.

Consider a research study in which we want to compare differences in the mean speech perception for children with hearing loss to children without hearing loss. There are multiple statistical approaches that could be applied to analyze differences between groups. Although scientists in nearly every discipline are familiar with the use of a two-sample Student's t test in this situation, confusion may arise when the assumptions of independence, normality, and equal variances are violated. An investigator must decide whether to immediately jump to a nonparametric analysis, implement a Welch adjustment for unequal variances, employ a repeated-measures analysis of variance (ANOVA), or transform the outcome variable, among many other options. All of these possible alternatives may produce the same conclusion, meaning the statistical approach we choose is inconsequential in many cases. On the other hand, we might obtain wildly different results depending on our choice of statistical method; understanding why the violation of assumptions can alter the behavior of statistical procedures is critically important to good statistical practice and making inferences based on the results of statistical analyses.

In most cases, there is not a single statistical approach that must be applied to solve a given research question, even when there is a clear tradition or common practice. Importantly, every statistical method comes with advantages and limitations. Practitioners should be familiar with the benefits and drawbacks of the procedures they employ and use that knowledge to choose methods that credibly answer the research question of interest. Our goal is not to provide detailed mathematical explanations of these tradeoffs but rather to focus on intuitive and practical recommendations when performing analyses, reporting results, and interpreting findings. We begin by discussing significance reporting and introducing the basic ideas behind hypothesis testing. We next discuss the ubiquitous use of the p value and what every user of a p value should know. The discussion of statistical significance via the p value is followed by measures of clinical significance through the appropriate use of effect sizes. We conclude by offering thoughts on regression analysis, model selection, and multiple comparisons.

Statistical and Clinical Significance

Significance reporting.

Research findings are often reported in terms of statistical and clinical significance, but it is very easy for both the producers and consumers of research to misuse or misinterpret these tools. Statistical and clinical (or practical) significance provide different pieces of important information. Ideally, both statistical and clinical significance should be described in reports and analytical results. Recall that statistical tests are generally devised as a choice between the null hypothesis (e.g., the average speech perception score for children with hearing loss is the same as the average speech perception score for children with normal hearing) and an alternative hypothesis (e.g., the average speech perception scores differ between children with and without hearing loss). To test a hypothesis is to ask whether we have enough scientific evidence to “reject the null hypothesis” and conclude that there is enough scientific evidence to conclude that the alternative hypothesis must be true (e.g., the speech perception means for children with hearing impairment and children with normal hearing are different). When we “do not reject the null hypothesis,” we write that there is not enough evidence to conclude that the group means differ; we do not make positive conclusions (e.g., “the two group means are actually equal”). The phrase “statistical significance” simply indicates that we have satisfied a prespecified rule (how far apart the means are relative to the standard error), which allows us to reject the null hypothesis in favor of the alternative hypothesis. This is most commonly assessed using p values, which we discuss in more detail in the p Values section. The result of our reject or do-not-reject decision can be either correct or incorrect. If we reject the null hypothesis in favor of the alternative hypothesis, but the null hypothesis is actually true, then we have made a Type I error. For example, a Type I error occurs when we claim two groups have different means when the means are in fact equal. If we do not reject the null hypothesis, but the alternative hypothesis is the true one, then we have made a Type II error. This transpires when we do not claim that two group means are different when they really are different.

Clinicians and researchers should recognize that statistically significant findings are not always practically or clinically significant. Statistical and clinical significance are often decoupled for large data sets because p values are strongly affected by the sample size. For example, we may find that the mean ages between two participant groups are significantly different statistically but that the observed mean difference is only 0.08 years (1 month). Unless this difference occurs at a point in development where the outcome of interest is likely to change rapidly over a short period, an age difference of 1 month between groups is unlikely to be clinically important. Reporting just the p value without highlighting the practical implications of the 1-month difference could be misleading.

Confidence intervals can help to contextualize significance tests and effects. Confidence intervals give a range of plausible values for a particular effect of interest. As such, they can be used to test hypotheses by checking whether the lower and upper bounds contain the hypothesized value of the quantity of interest. In addition, confidence intervals can also give an impression of clinical significance, which is discussed in more detail below in the Effect Sizes section in the context of “effect size.” Briefly, an effect size can be as simple as reporting parameter estimates such as the sample mean, the mean difference between two groups, or the slope estimate in a regression analysis. Confidence intervals are subject to the same Type I and Type II error rates as significance testing more broadly, and the specific intervals given are often misinterpreted by researchers. Nevertheless, confidence intervals provide additional clinical effect information beyond the simple statistical significance of a finding and are discussed in more detail in the Effect Sizes section.

Unlike p values, the practical size of an effect does not change based on a sample size and provides a crucial piece of information that should be reported. In general, more time and space in scientific reports should be devoted to the discussion of the practical significance and scientific impact of detected effects. To be most impactful, scientific publications should convey both the evidence of an effect (statistical significance) and the practical impact of the detected effect (clinical significance). In addition, because different scientific audiences may have different tolerances for Type I errors, we recommend that researchers report actual p values, rather than just whether or not an effect is significant. Whereas preference or convention leads many researchers to be satisfied with a 5% Type I error rate ( p < .05), others may prefer 1% or 0.1%, especially if the consequences of such an error would have a major impact on the field or alter an established scientific premise or clinical practice. In the next two subsections, we discuss p values and effect sizes in greater detail.

Although every introductory statistics class requires students to memorize their definition, p values have long been misunderstood and are often misused, misinterpreted, and increasingly criticized. At least one journal (Basic and Applied Social Psychology) has even taken the step of banning p values ( Trafimow & Marks, 2015 ), and another has suggested using a more conservative p -value threshold to determine statistical significance to .005 ( J. P. A. Loannidis, 2018 ). These controversies have led to ongoing debate and discussion across a wide range of scientific fields about the appropriateness of p values as the main criterion for judgments about statistical significance. To shed more light on the proper use and interpretation of p values, the American Statistical Association released a statement in 2016 ( Wasserstein & Lazar, 2016 ) with six principles to consider for the proper use and interpretation of the p value. They are the following:

  • p values can indicate how incompatible the data are with a specified statistical model.
  • p values do not measure the probability that the studied hypothesis is true or the probability that the data were produced by random chance alone.
  • Scientific conclusions and business or policy decisions should not be based only on whether a p value passes a specific threshold.
  • Proper inference requires full reporting and transparency.
  • A p value, or statistical significance, does not measure the size of an effect or the importance of a result.
  • By itself, a p value does not provide a good measure of evidence regarding a model or hypothesis.

As we tackle the question of the usefulness of the p value, we need to understand what it is and what it is not. By definition, the p value is the probability of observing a test statistic, which is as extreme as or more extreme than that which was observed, assuming that the null hypothesis is true. If this probability is sufficiently low (e.g., below an acceptable Type I error rate) for the purposes of a given study, then we consider this sufficient evidence that the null hypothesis is likely not true and that we may favor the alternative hypothesis. The p value is not a tool for deciding which of two competing hypotheses is more likely, given the observed data.

In the frequentist statistical paradigm (the most common approach to statistics and data analysis), the hypothesis is not random, so we do not assign a measure of probability directly to it. From this perspective, the actual hypothesis is either true or false, and this fact does not change simply due to our inability to know the truth with certainty (e.g., the two means are equal, or they are not equal). Instead, we measure the likelihood that the data could have arisen if the null hypothesis were true. In order to accomplish this, we assume that the null hypothesis is true (e.g., the mean speech perception rates are equal for children with hearing impairment and children with normal hearing) and then define a rule to reject the said hypothesis if the observed data would be sufficiently improbable if that hypothesis were indeed true (e.g., these means are more than 2 SD s apart). If the observed data would have been unlikely to have arisen under the conditions specified in the null hypothesis (e.g., the sample means for our two groups are too far apart for them to have come from two distributions with the same mean), we consider that evidence against the null hypothesis. This process does not allow for a probability comparing the two competing hypotheses.

In some settings, researchers do desire a method to compare the likelihood of competing hypotheses. In such settings, Bayesian statistical approaches may be more useful. In the Bayesian paradigm, one can evaluate the probability of the null hypothesis being true versus the probability of the alternative hypothesis being true, because the Bayesian interpretation of probability is fundamentally different from the frequentist interpretation. Broadly speaking, Bayesian probability is a tool to quantify knowledge and uncertainty. Bayesian statistics uses probability to describe what is known before data are collected and to update that knowledge based on how much is learned after collecting data. More detail on Bayesian statistics is given in this issue in Oleson et al. (2019) and McMillan and Cannon (2019) .

p values suffer from other drawbacks besides the confusing definition. Consider a two-sample problem to compare two group means such as testing whether the mean speech perception score of the population that is hard of hearing is significantly different from the mean speech perception score of the population with normal hearing. Although the null assumption that population means are equal is statistically useful, in real-world settings where we cannot randomly assign group membership, we know a priori that the two population group means are not the exact same value. In our example of speech perception scores, it seems improbable that a language outcome score for the group with hearing impairment has the same population mean as the group with normal hearing. Our primary interest is to determine whether a statistically detectable and clinically relevant difference exists. Even in experimental settings, if there is a difference worth testing, there is often a good reason to suspect that at least an infinitesimal difference between group means exists. Nevertheless, we assume that the population means are equal in a null hypothesis. In order to demonstrate evidence of a difference between them, we must first naively assume that there is no difference. Whenever the population means are even slightly different, we know that we can make a p value small enough to declare statistical significance simply by choosing a large enough sample size (e.g., a high enough power). Indeed, researchers who fail to reject null hypotheses are often advised to increase their sample size. This practice is not statistically appropriate in part because it does inflate the Type I error. In this sense, p values by themselves often tell us more about sample size than anything practically meaningful about the size of the effect. Moreover, p values are constructed under the statistical model that we assumed: Any departures from the assumptions of that model impact the reliability of the p value.

If we use common, incorrect statistical practices in speech, language, and hearing science research, including sampling from finite populations without correction, obtaining correlated samples that are not accounted for, or sampling from populations with different distributions from those assumed by particular statistical procedures, the applicability and reliability of p values are greatly diminished. Therefore, the statistical analysis that is used should be carefully determined to appropriately reflect the problem at hand and that the relevant assumptions should always be considered and checked prior to making inferences based on statistical results.

Effect Sizes

An “effect” or “effect size” is a measurement of a phenomenon of interest, whether an expected change in an outcome in response to a treatment, a difference between group means, or a ratio of the odds of an outcome in two groups. Importantly, the specific effect size that is chosen should provide insight concerning a meaningful study question.

Effect sizes can be subdivided into two groups: “standardized” or “relative” effect sizes and “unstandardized” or “absolute” effect sizes. Unfortunately, which kind of effect is being presented in a given analysis is not always clear. Cohen's d is a commonly used relative effect size, whereas our previous example of 1-month difference in age is an example of an absolute effect size. Many formulas for the power of statistical procedures and sample size of study designs are given in terms of Cohen's d , because the power to reject a null hypothesis depends on the relative extremeness of the alternative hypothesis; Cohen's d gives a standardized measure of how far an estimated effect is from a hypothesized value, relative to its standard error. This gives a convenient scale on which to compare and interpret mean differences but suffers from the same problem as p values: Cohen's d does not measure the practical significance of a difference but is instead more closely related to statistical significance. Using our previous example, if we detect a statistically significant difference in mean age between two groups, we can equivalently expect that the difference in means is large relative to its standard error. Lenth (2012) provides an excellent summary of the shortcomings of comparisons of relative effect sizes. A clinically meaningful effect is typically better evaluated by examining the magnitude of the absolute mean difference.

Absolute effect sizes for hypothesis tests comparing means are simply the difference between the means of interest. Statistical software for most statistical modeling frameworks will output absolute effect sizes based simply on the parameters reported by statistical software. Obtaining relative effect sizes in the style of Cohen's d in modern statistical models can be somewhat more complex given the potential difficulty of estimating the standard error of the difference between groups, which is the denominator term in the calculation of Cohen's d . Although methods exist to compute relative effect sizes for more complicated models ( Brysbaert & Stevens, 2018 ; Selya, Rose, Dierker, Hedeker, & Mermelstein, 2012 ; Westfall, Kenny, & Judd, 2014 ), we generally prefer to rely on more interpretable absolute effect sizes.

Confidence intervals provide another perspective on absolute effect sizes. Although they suffer from some of the same interpretability challenges as the p value, they do give us more direct information on the range of plausible values for the parameter of interest. Consider the difference between speech perception scores between two groups again. For two independent groups, a two-sample independent groups confidence interval is typically computed using the difference in the means and a weighted average of the variances of the two groups (a pooled variance). Note that we say typically because we are assuming equal variances between the two groups and that the difference in means approximately follows a normal distribution, and any deviations from those assumptions would require alternate methods. The confidence interval is then centered at the mean difference, and we add and subtract the standard error (square root of the pooled variance) times our critical value. The result is an upper limit and a lower limit of confidence of where we believe the true population mean difference might be. The interpretation challenges come from the fact that the performance guarantees (confidence levels) concern the repeated process of how confidence intervals are constructed in general, rather than the specific numbers produced in one single statistical analysis. For example, in a study where the mean difference in language standard scores between two groups of children is 4.51, with a valid 95% confidence interval of [3.30, 5.72], we have confidence that intervals constructed in this way will contain the true language standard score 95% of the time. No such statement can be made about the specific interval of 3.30–5.72. Even so, this range does give plausible values that are consistent with the observed data—a valuable addition to the practical understanding of the absolute size of an effect.

When reporting study results, it is important to report measures representing both the statistical significance and clinical significance of the study. Absolute effect sizes generally carry the most information regarding clinical importance for the study and should be reported. Generally, this should be in terms of the parameter estimate and the confidence interval for the estimate. Relative effect sizes can also be informative in some situations but carry additional complexity and can conflate statistical and practical significance for practitioners and readers.

Regression Topics

Regression and anova.

A common statistical technique employed in the field is regression analysis. In its most basic form, a regression analysis includes one dependent variable that is related to the outcome via a line, although regression models can be made much more complex. The goal is generally to test whether all or some of the independent/explanatory variables in the model are related to the dependent/outcome variable. Those independent variables may be continuous or categorical. In the event that there is a single categorical independent variable, then the resulting regression model is commonly referred to as ANOVA . Although classical regression and ANOVA were developed separately, ANOVA is simply a special case of regression, where regression can accommodate more complicated relationships between the dependent variable and the independent variables.

In a regression-type model, the slope parameter estimates themselves provide a measure of effect size. In cases where multiple groups are present (such as in ANOVA or regression with categorical variables), the effect of interest may be given by the estimate of a contrast or a single parameter estimate comparing one group to a reference group. See Bring (1994) for a full discussion of regression effect sizes. In Walker et al. (2014) , regression models were used to investigate relationships among predictor variables and service delivery for a group of children who were hard of hearing. The independent variables were gender, test site, maternal education level, immediate family history of hearing loss, and degree of hearing loss measured by better-ear pure-tone average. They found that, after controlling for all of the variables, only degree of hearing loss was significantly related to the dependent variables age at first diagnostic evaluation (β = −0.36, p = .003), age at hearing loss confirmation (β = −0.42, p = .001), and age at hearing aid fitting (β = −0.37, p = .011). By reporting the β (slope) values, we can immediately determine how better-ear pure-tone average is related to each of these age-related outcome variables. They also found that only gender was significantly related to length of the delay between hearing loss confirmation and enrolling in early intervention (β = −3.34, p = .024). Through reporting of the β value as an effect size, we immediately know that girls had an estimated delay that was 3.34 months shorter than boys, and we can readily assess the clinical impact those months will have on the children.

In ANOVA, we are often confronted with the need to adjust our outcome variable of interest by a covariate that is continuous. A classical approach to performing this adjustment is analysis of covariance (ANCOVA). Recall that ANOVA is designed to compare group means by measuring the between-group variance relative to the within-group variance. ANCOVA is a method that mathematically adjusts the group means to take into account the values of the covariate (e.g., age) and then performs ANOVA on the covariate-adjusted means. However, just as ANOVA is equivalent to a regression analysis that includes only a categorical variable, ANCOVA simply adds a continuous variable to be adjusted for to that regression model. For example, an ANCOVA that examines differences in speech recognition for children who are hard of hearing and children with normal hearing adjusting for age is the same as a linear regression analysis that includes age and hearing status (normal hearing or hard of hearing) as predictor variables. General linear hypothesis tests can still be performed within the regression model framework. General linear hypothesis tests include what many in the field call post hoc tests. Technically, post hoc tests are those tests, usually pairwise comparisons, that are only considered after the results of the global tests are found. If these pairwise comparisons are planned from the beginning of the study, then they are not technically post hoc tests.

Moreover, regression models and their generalizations offer a great deal of flexibility to include additional covariates, add random effects, modify the residual error structure, do nonlinear transformations, and more. The addition of random effects to a regression model to create subject-specific curves and account for within-subject correlation is referred to as linear mixed-effects regression models or linear mixed models. More details on mixed models can be read in our companion article ( Oleson et al., 2019 ). Although ANOVA and ANCOVA are familiar statistical procedures with a lot of history, it is preferable to use the regression framework for the task of comparing group means.

Model Selection

Often, we encounter the situation of deciding what independent variables to include in our regression model. This process of deciding which variables to include, and which to not include, is known as model selection . For example, Walker et al. (2014) were interested in predictors of the dependent variable age at hearing aid fitting. The independent variables were gender, site at testing, maternal education level, immediate family history of hearing loss, and degree of hearing loss. The variables included in the final model were included because of specific hypotheses about the factors that influence hearing aid use from theory and the previous literature on hearing aid use in children. Model selection refers to deciding what subset of the full list of independent variables should be included in the final model.

Model selection is broader than just regression and arises in all forms of statistical inference. Investigators must identify a model that can address the research questions of interest using the variables that were collected as data. Ideally, scientific theory should be the foundation for the process of model selection, comparing among a small set of scientifically plausible models. Some approaches to model selection are based on the principle of parsimony: The best statistical model is that which includes all the essential variables and nothing more. In practice, however, the most parsimonious model for a specific research question can be difficult to identify. In many exploratory studies, we gather data without a full understanding of what the important relationships are, which covariates need to be adjusted for, and what patterns of correlation in longitudinal studies are likely to be appropriate. Although model selection is a large topic area and an active field of statistical research, common techniques in a frequentist setting can be broadly divided into two categories: algorithmic approaches and researcher-driven exploration. The process of model selection is crucially important and can impact the outcome and reliability of hypothesis testing procedures, as well as the inferences and conclusions of a research study.

At the core of any model selection procedure is the ability to compare selected models of interest to determine which better fits the data. This comparison can be accomplished for nested models in a regression setting using F tests, which test the null hypothesis that the collection of variables to be added to the model does not explain a significant amount of variability in the outcome above and beyond the currently included variables. More generally, we can compare frequentist models using information criteria such as the Akaike information criterion (AIC). Models with smaller AIC values are considered to have better fit to the data. Algorithmic model selection approaches build on these concepts by sequentially considering modifications to a model. For example, forward selection starts with a base model and proceeds to consider adding terms to a model. Terms are added at each step if they meet an inclusion threshold, which can be based, for example, on p values or information criteria. Similarly, backward selection starts with a large model and considers terms for removal. Researcher-driven exploration may use some of the same tools to compare models, but decisions on what models to explore and select are made by the researcher. This process of model selection may be informed by scientific knowledge, formal model comparisons, or conscious/subconscious preference for certain model features or results.

Although it is clear why informal exploratory analysis can lead to problems with inflated Type I error rates and reproducibility, many practitioners are surprised to discover that formal techniques such as stepwise model selection are similarly problematic. In each case, the output generated by statistical software after a model selection routine is performed is indistinguishable from output obtained from a prespecified analysis. For most statistical procedures, the reported results are based on the assumption that data were collected according to a simple random sample from a large population, and then a single model was fit. These assumptions are not met when data-driven model decisions are made, and these assumption violations can endanger the validity of statistical inference.

To illustrate this point, we highlight several simulation results from a regression example. Replicate data sets (50,000) are simulated with 10 hypothetical covariates and a normally distributed outcome measure and are generated under the global null hypotheses that all of the regression coefficients are zero. Each data set has n = 100 observations. Two primary hypothesis tests are of interest. First, we consider the setting where one covariate addresses a primary study question, and the other nine covariates are included to adjust for potential confounding. In the second, we consider the overall F test for the (true) null hypothesis that all of the covariate beta coefficients equal zero. For prespecified analyses conducted without model selection, we have theoretical guarantees that the Type I error rate will not exceed whatever nominal threshold we specify.

For a chosen Type I error rate of 0.05, we observe that choosing large or small models presents no problems in the absence of model selection. In line with our theoretical expectations, the observed Type I error rate for the analysis of just the single variable of interest produced a Type I error rate of 0.0502, whereas an analysis of all 10 covariates with pairwise interactions produced a comparable Type I error rate for this comparison of 0.0496. The overall F -test results were similar.

In the presence of forward stepwise model selection based on AIC, however, the hypothesis test concerning our primary variable of interest had a Type I error rate of 0.0645, and the overall F test had a Type I error rate of 0.4314. Therefore, just by applying basic model selection algorithms, we are increasing our probability of incorrectly rejecting the null hypothesis. Although these results are quite troubling, especially for overall F tests, the situation in real analyses may be even worse, as actual data tend to exhibit correlation among the independent variables or various types of confounding, driving up variability of parameter estimates and the likelihood of incorrect conclusions. With this in mind, it is incumbent upon practitioners to clearly delineate between exploratory analyses and confirmatory analyses in scientific reports and to clearly describe any model selection procedures that were employed in a study. By default, p values only attain their advertised performance for prespecified models. Code and complete results of the simulation are provided in Supplemental Material S1 .

Multiple Comparisons

Statistical models may require comparisons of several effects within an overall model. Traditionally, scientists have been trained to adjust their statistical assumptions to be more conservative to account for multiple comparisons to avoid the increasing risk of statistical errors as the number of comparisons increases (e.g., Aickin & Gensler, 1996 ). However, there are also costs to many approaches to accounting for multiple comparisons, including reducing statistical power. There are different schools of thought when it comes to multiple comparisons and many relevant summary articles. See overviews by Saville (1990) , Bender and Lange (2001) , or Cao and Zhang (2014) for more in-depth discussions of this issue. Rather than provide a review of the myriad methods of accounting for multiple comparisons in statistical models, we lay out some general points to consider regarding the topic.

The primary reason that researchers are advised to do a multiple-comparisons adjustment is to strictly control the overall (familywise) Type I error rate. In summarizing the alternative approaches for adjusting for multiple comparisons, we will consider three different general approaches. We could (a) perform no adjustment and accept individual Type I error rates, (b) adjust our alpha level to preserve a predetermined familywise error rate, or (c) adjust the alpha level to allow for a specified acceptable false-positive error rate.

The first approach to multiple testing is applicable when an alpha level adjustment may not be required. Bender and Lange (2001) argue that multiple comparisons should be used in confirmatory studies for the primary outcome of interest and that they are not necessarily required for exploratory studies. The researcher should clearly define the primary outcome and identify which comparisons correspond to that outcome. This may be a small subset of analyses that are performed, where the rest of the analyses are secondary and perhaps dependent upon the results of the primary question. If we have a truly controlled and confirmatory analysis, then we do want to reasonably control this alpha level. There is also the question of making Type II errors where we do not detect an important difference. In speech, language, and hearing studies, where sample sizes tend to be small, the alpha level adjustments reduce the significance level, which also increases the Type II error. It is critical to report absolute effect sizes in these situations.

The most common approach implemented for multiple comparisons is to adjust the alpha level to preserve a predetermined familywise Type I error rate. The Bonferroni adjustment is the most common technique used. For all pairwise comparisons, some will choose a Tukey–Kramer adjustment, but there are many more ways of adjusting alpha to control familywise error rates. Although it is clear that these adjustments are conservative, it may not be as clear the assumptions that are being made by such an adjustment. In an adjustment to control the overall Type I error, a critical assumption is that all null hypotheses are correct and that we want to jointly make only a 5% chance of falsely rejecting at least one of those. However, we happen to know that it is highly unlikely that all null hypotheses are true, as we outlined in the Significance Reporting section. These adjustment techniques make the most sense in a highly controlled confirmatory study with a single outcome of interest. In many studies, especially those that include various covariates (e.g., age, hearing loss severity, gender), we do expect many of the null hypotheses to be false and would be surprised not to find significant evidence against them. For example, a study in which age is adjusted for as a known confounder is expected to find a significant effect due to age. As an alternative example, a study with a placebo arm, a known effective treatment arm, and a novel treatment would be expected to reject the null hypothesis that the existing treatment and placebo produce the same mean. Assuming the global null hypothesis as a basis for Type 1 error rate correction is often unrealistic and unnecessarily conservative.

The third approach is to adjust the alpha level to allow for an acceptable error rate. This differs from approaches that attempt to control the overall Type I error rate because the goal is to control the proportion of our “significant” results that are incorrect, rather than the probability of making any such mistakes. The false discovery rate (FDR; Benjamini & Hochberg, 1995 ) and the procedures for controlling it were developed for this purpose. This method makes more intuitive sense for how we think about testing, but it does not guarantee an overall prespecified Type I error rate. FDR-adjusted p values control the number of false discoveries (Type I errors). For example, an FDR of 0.05 implies that, on average, 5% of significant tests will result in false positives under the null hypothesis. The FDR-adjusted p value can be far less conservative than a Bonferroni adjustment but still addresses the goals of controlling Type I errors when multiple comparisons are made.

The goals of this article were to (a) present statistical concepts and methods that we regularly see implemented and misunderstood in speech, language, and hearing sciences research and (b) offer additional insights or alternatives to those concepts and methods. Like other disciplines, the field of statistics has evolved over time to accommodate the realities of modern research involving human subjects. Although the traditional statistical methods that we have discussed in this article still have relevance and specific uses, often other tools can better and more accurately answer the research question of interest and offer greater flexibility for more complex research designs. It is up to scientists in the field to continue educating themselves in modern statistical practice to find statistical approaches that fit their specific goals and to work with statistical experts throughout the research process.

This education begins with a better understanding of the p value and its worth. When the p value is reported in conjunction with an appropriate measure of the effect size, then it gives the researcher important information about the study findings, both statistically and clinically. It is imperative to consider the information actually conveyed by a particular measure of effect size and how it informs the statistical results and practical implications of a given study. Although many of the concepts described in this review are basic statistical principles, the misunderstanding or misinterpretation of these concepts is a substantial threat to the validity of our research findings. To help minimize the potential for statistical errors, researchers in the speech, language, and hearing sciences can do the following:

  • Understand how p values are calculated and what p values represent. The 2016 recommendations of the American Statistical Association regarding p values ( Wasserstein & Lazar, 2016 ) can help scientists to avoid common misconceptions about p values and understand the difference between statistical and clinical significance.
  • Report measures of statistical and clinical or practical significance as part of articles or reports summarizing research findings. Presented together, metrics of statistical and clinical significance enhance the interpretation of research and make the effects meaningful for clinicians and patients who are much more likely to be interested in the magnitude of the effect in terms of a specific outcome rather than the statistical significance alone.
  • Include confidence intervals for effect sizes. The appropriate use of confidence intervals conveys the potential range of plausible values around an effect and can allow consumers of research to understand the influence of variability on the precision of reported effect sizes.
  • Choose statistical approaches that allow for modeling complexity over methods with more rigid assumptions such as ANOVA or ANCOVA. Using flexible methods such as regression or mixed models can expand the breadth of research questions that can be evaluated beyond examining differences between groups or across conditions.
  • Develop model selection procedures based on scientific knowledge and theory that are parsimonious solutions to complex phenomena. Different iterations of the same statistical model should be compared using established information-based methods, such as comparisons using AIC or Bayesian information criterion.
  • Use methods for controlling for multiple comparisons within statistical models that are specific to the goals of the research rather than always using overly conservative approaches that control for familywise error rate, such as Bonferroni adjustment. Decisions about the appropriate method for controlling for multiple comparisons should occur prior to the statistical analysis based on the goals of the comparisons and design of the study.

The goal of reporting results from statistical analyses in articles should be to present new clinically relevant findings or suggest future research opportunities. Readers of the work should be able to replicate the experiment and the analysis. The statistical methods should be written with enough detail that a data analyst could read it and replicate the analysis. Furthermore, code and data should be provided when feasible to promote transparency and reproducibility. Statistical methods are designed to provide good results under uncertainty but always include the possibility of error. With this in mind, replication is an essential part of scientific progress, and wherever possible, researchers should facilitate these efforts. There are many opportunities to apply these principles in the speech, language, and hearing sciences, and it is our hope that this article will help orient investigators to the problem of selecting appropriate and robust statistical models.

Embracing Business Practices That Actually Improve the World

  • Caitlin McElroy,
  • Roberta Roesler,

business speech science research

What organizations need to know about adopting “regenerative” practices that actively help ecosystems and communities — not just minimize harm to them.

The science is clear that the track we’re on is not good enough to prevent further catastrophic effects from climate change. We’re beyond a point where we can merely aim to do less bad; we need to actively regenerate the areas that have experienced significant degradation. Regenerative businesses aim to improve ecosystems and communities, rather than simply minimize harm to them. But in this rapidly expanding, philosophically attractive, and still unsettled space of regenerative business, those who want to take action on regeneration are working from many definitions and approaches. The authors unpack some of the competing definitions of regeneration and show how certifications can help organizations ensure their regeneration strategies and practices support a truly regenerative future.

At the COP28 conference late last year, regeneration emerged as a focus for business leaders. Regenerative businesses aim to improve ecosystems and communities, rather than simply minimize harm to them. It’s no wonder it’s a hot topic — the science is screaming at us that the track we’re on is not good enough to prevent further catastrophic effects from climate change. According to the Stockholm Resilience Centre, we’ve already crossed six of the nine planetary boundaries , “ processes that are critical for maintaining the stability and resilience of [the] Earth system as a whole.”

Understanding Business Speech Writing

Before we delve deeper into the topic, we must explain the essence of business speech writing.

Speech writers in the business world are responsible for crafting carefully structured scripts that guide speakers' addresses. Although speech writing is commonly associated with political contexts, the demand for this skill extends beyond politics. Various sectors, ranging from business executives to motivational speakers, seek assistance in developing impactful speeches tailored to engage and resonate with their specific audience.

This is one of the reasons why the topic of speech writing is being studied across different institutions of higher learning.

Key Considerations for Business Speech Topic Selection

Now let's take a look at what to consider when selecting a hot business topic for your speech:

●       The intended audience: First, you must consider your target demographic as well as their interests and knowledge level. This ensures that the chosen topic is both meaningful and engaging for them

●       The purpose of the business speech: Ensure you understand what you want from the address. Clarity of purpose is always paramount

●       Relevance: As clichéd as this may sound, ensure that you choose a topic that associates with relevant issues in the business landscape or industry

●       Length and Scope: Finally, evaluate the time allotted for your speech and work within this time frame. This ensures that you choose a topic with enough content and that is relevant to make it worthwhile

Communication Sciences and Disorders

Us news & world report ranks iowa audiology, speech-language pathology among the top in the nation.

Two UIowa programs in the Department of Communication Sciences and Disorders (CSD) are once again recognized among the best in their field according to the U.S. News & World Report Best Graduate Schools rankings for 2024 .  

Iowa’s audiology program is again ranked second best in the nation and remains the top public institution training audiologists. The speech-language pathology program climbed in the rankings to fifth and is now the third-ranked public institution. CSD is housed in the College of Liberal Arts and Sciences.   

New rankings of nation-wide  Audiology and  Speech-Language Pathology graduate programs is available on the USNWR website.

“We are focused on training outstanding audiologists and speech-language pathologists,” said Eric Hunter , DEO and Harriet B. and Harold S. Brady Chair in Liberal Arts and Sciences. “These rankings recognize the daily efforts of our remarkable faculty and staff, who consistently strive to provide exceptional education to our students.”  

“Together, we are shaping the future of audiology and speech-language pathology, and we will continue to lead the way in delivering excellence,” Hunter added.  

Hunter, who has been at Iowa since August 2023 and is a nationally recognized expert in the field, was the first hire under the University of Iowa’s Transformational Faculty Hiring Program, which is aimed at attracting world-class faculty to strategic programs and areas of excellence. He received a PhD from Iowa’s Department of Communication Sciences and Disorders program in 2001.  

Iowa has long been a leader in communication sciences and disorders dating back to 1897, when the university, led by Carl Seashore’s pioneering work, developed speech pathology as a discipline of study.  

“CLAS is proud of our faculty and staff who continue to guide this storied program into the future,” said Dean Sara Sanders. “Because of their tremendous talent and dedication to their research and teaching, CSD continues to be at the forefront of audiology and speech-language pathology.”   

The university, college, and department continue to lead, ensuring students access to unparalleled opportunities. Construction has started on a new $249 million building that will provide a state-of-the-art learning space for Iowa students studying in the Department of Communication Sciences and Disorders, Department of Health and Human Physiology, and the Carver College of Medicine’s Department of Physical Therapy and Rehabilitation Science.  

Substantial completion of the building is anticipated in 2025.

Duke CNAP Welcomes First Speech-Language Pathologist

Profile photo of Shanika Phillips

Duke’s Cognitive Neuroscience Admitting Program (CNAP) is set to welcome its first speech-language pathologist as a doctoral student. Shanika Phillips Fullwood , a clinically certified SLP with over a decade of experience, will begin her studies in the fall of 2024.

Her enrollment reflects a promising shift toward innovative, interdisciplinary approaches in brain and language research.

Phillips Fullwood works at Moses Cone Memorial Hospital in Greensboro, treating adult patients who have neurogenic disorders, associated with stroke, traumatic brain injury, and spinal cord injury. She serves as the acute rehab neuroscience diagnostic specialist, a role that involves coordinating with physical therapists, occupational therapists, and SLPs to ensure the use of evidence-based practices.

In addition to her clinical work, she is an adjunct lecturer at her alma mater, Brooklyn College, CUNY, and she contributes to research on neurogenic communication disorders in the lab of Jamila Minga, PhD, CCC-SLP . Phillips Fullwood’s work in the lab includes training undergraduates in transcription checks for the Right-Hemisphere Brain Damage (RHD) Bank and participating in brain mapping studies to identify regions associated with specific deficits.

She’s also co-authoring manuscripts focused on the impact of culture on communication and the development of a diagnostic code for apragmatism, work that aligns with her research interests.

As a doctoral student, Phillips Fullwood plans to focus on the cognitive aspects of communication, particularly how right-hemisphere strokes affect language and communication abilities. Her interest in this area developed during her time as an SLP in Indiana, where she encountered a number of patients with right-hemisphere strokes who had trouble with communication.

These patients struggled to stay on topic and understand questions, even though their language center – which is typically associated with the left hemisphere – was not affected.

“I would bring up these concerns during our interdisciplinary team meetings to the physical medicine doctor, and the response often was, ‘Well, they didn't have a left-hemisphere stroke, they had a right-hemisphere stroke, so they shouldn't have communication difficulties,’” she said.

This led her to delve deeper into the research to understand whether these kinds of communication deficits have been documented in the literature.

“There was some evidence supporting that, but still, there's a bias toward the left hemisphere being the only hemisphere that's responsible for communication,” she said. “I thought, ‘Well, it's time for me to go back and do my PhD,’ which was always my goal.”

Known for its interdisciplinary approach, CNAP provides students with the opportunity to engage with faculty across multiple departments and fields at Duke, such as neurobiology, psychology, psychiatry, biomedical engineering, and philosophy .

Students undergo 18 months of coursework and laboratory rotations, gaining foundational knowledge in cognitive neuroscience. After that, they select a department and two advisors to guide their thesis research, furthering their specific interests through an affiliate graduate program or department.

“The fact that CNAP is so interdisciplinary was really attractive to me,” Phillips Fullwood said. “I felt that this program would serve me a lot better than a PhD in communication sciences because I'll be able to tap into some of the techniques they're using in neuroscience to get a better understanding of the communication piece.”

Her enrollment in CNAP demonstrates the interdisciplinary approach necessary for advancing the field of cognitive neuroscience. It also highlights the opportunity to integrate speech-language pathology into Duke's broader research and academic offerings. Currently, the school does not offer a training program for communication sciences and disorders at the master’s or doctoral level.

Through her work, Phillips Fullwood hopes to help bridge the gap between clinical speech-language pathology and cognitive neuroscience in treating patients with right-hemisphere strokes who have communication deficits.

“ I believe that we must have a good understanding of why this patient is doing what they're doing to inform how we evaluate and treat them,” she said. “ If we improve this piece, then we'll be able to help translate that into better diagnostic tools, better assessment methods, and better, more formal ways for treating this than we currently have.”

Frequently Asked Questions

What are gpus and cpus.

GPUs (graphics processing units) are specialized processors designed to handle certain complex computations efficiently, commonly used in tasks such as rendering high-resolution graphics and performing parallel computations in fields like machine learning and artificial intelligence. CPUs (central processing units) are the central component of a computer responsible for executing instructions, managing tasks, and coordinating the operation of various hardware components, serving as the brain of the computer.

GPUs have become prominent due to their exceptional parallel processing capabilities, which make them highly efficient for high-performance computing (HPC) tasks. Additionally, advancements in GPU technology have led to significant improvements in graphics rendering, gaming experiences, and visual computing applications, further driving their prominence in various industries and fields.

How many GPUs are in the Georgia Tech AI Makerspace and what makes them important?

Phase I of the Georgia Tech AI Makerspace comprises a total of 160 NVIDIA H100 Tensor Core GPUs. 20 NVIDIA H100-HGX servers contain 8 GPUs each. The benefit of GPUs is that they provide extremely performant accelerators designed specifically for AI, with a very large unified memory space that can accommodate very big models.

It’s also noteworthy that an important capability of AI is low-precision performance. These nodes provide roughly 640 petaflops (PF) of theoretical 8-bit floating-point for 8-bit integer (FP8/INT8) capability, combined with the 640 gigabytes of GPU memory per server.

Why are there both GPUs and CPUs in the Georgia Tech AI Makerspace? 

CPUs and GPUs are optimized for different kinds of calculations, so it’s useful to have both available. Optimized software will perform certain steps of code on the CPU and others on the GPU to maximize performance.

CPUs are “standard” general-purpose chips that work well for many calculations. GPUs are specialized. A server cannot run without a CPU. The CPU handles all the tasks required for all software on the server to run correctly. 

GPUs are accelerators with more focused computational hardware that rely on a separate host system to operate.

workers loading in GPU hardware

Who will manage the infrastructure of the AI Makerspace? 

The AI Makerspace infrastructure will be supported by Georgia Tech’s Partnership for an Advanced Computing Environment (PACE). PACE provides sustainable leading-edge Research Computing and Data (RCD) cyberinfrastructure, software, and support for research and education requiring high performance computing and other advanced research computing infrastructure. 

PACE is a collaboration between Georgia Tech faculty and the Office of Information Technology (OIT) focused on HPC.

Is the AI Makerspace scalable?

Yes. Each GPU can be physically partitioned into 7 GPUs (with 1/8 the capability of the whole). With 160 total GPUs, the AI Makerspace can provide 1,120 concurrent GPUs to allow large numbers of students access simultaneously. 

How much power does the AI Makerspace require?

The new servers will draw about 140kW of power, compared to the 800kW PACE’s five existing clusters draw.

The theoretical 64-bit performance of the new hardware is 5.5 PF (petaflops, a measurement of computer speed of performing calculations). The existing PACE clusters altogether have about 4-4.5 PF of performance. This means that the new servers are significantly more energy efficient for the same computational capability than older systems.

Purdue’s I-EaT Research Lab examining swallowing and speech in children with cerebral palsy

Georgia Malandraki

Georgia Malandraki

Written by: Tim Brouk, [email protected]

Understanding the role head and neck muscles play in eating and talking for children with cerebral palsy (CP) is a research effort led by Georgia Malandraki , professor in the Purdue University Department of Speech, Language, and Hearing Sciences , and her I-EaT Lab . The work was funded by the National Institutes of Health, the American Academy for Cerebral Palsy and Developmental Medicine, and the Purdue College of Health and Human Sciences .

“More than 50% of children and adults with cerebral palsy may have speech, feeding and swallowing difficulties,” Malandraki said. “Although there has been a lot of research on the gross motor and hand functions of this population and how to best rehabilitate them, there has been much less work on the underlying mechanisms that cause feeding, swallowing and speech difficulties. This has limited our treatment options for these children and was a gap that we wanted to address.”

Speech difficulties can result in children and adults with CP not being understood; feeling isolated; and having reduced academic, social and employment fulfillment. Swallowing difficulties can also lead to serious consequences, such as being undernourished, dehydrated or in severe cases, developing respiratory infections (pneumonia) from foods and liquids not being safely swallowed. These types of difficulties — swallowing and speech — may also co-occur.

Most of the available treatments for swallowing and speech difficulties in CP are compensatory in nature and mostly address the symptoms, according to Malandraki. For example, simple changes in the child’s head and neck position during meals can aid in swallowing, and specialized, padded eating utensils could be an easy investment for families if a child with CP is having feeding issues. Malandraki added that making meals with softer, easier-to-swallow food, such as a fruit smoothie instead of fruit that needs to be chewed, is another simple strategy when children have difficulty chewing. Speaking slower or using exaggerated mouth movements are some common speech strategies as well.

“To be able to effectively improve the speech and swallowing functions of children and adults with CP, it is first imperative to understand how their muscles and brains work so we can use that information as we develop new treatments that will not just focus on the symptoms,” Malandraki stated.

Understanding underlying mechanisms

Child wears sensors on their face and chin during a swallowing and speech study.

A child wears small muscle activity readers on their face to study how muscles activate during eating and speech tasks.

Through electromyography (small muscle activity readers), Malandraki and her team measured the head and neck muscle activity in 16 children with CP ages 7-12 and 16 children without the condition but the same ages.

The children with CP were tested at two sites, Malandraki’s lab and Nationwide Children’s Hospital in Columbus, Ohio. All had unilateral CP, a form of the condition where one side of the body is weaker than the other due to brain lesions affecting primarily one side of the brain. These children are usually more physically functional than children with more severe types of CP, such as quadriplegic CP, where both sides of the body are affected.

The children were able to feed themselves, and they were given a variety of food and liquids to swallow and were also asked to complete simple speech tasks. Through sensors attached around the mouth and under the chin, the researchers first found children with CP use these muscles much more than children without CP for both swallowing and speaking. This over-activation means these children were spending more energy to eat and speak than the typically developing control group.

“They show increased amplitude of muscle activity, indicating a lot of muscle effort,” Malandraki said. “So, they’re expending a lot of energy on both sides — the affected and unaffected — of the head and neck to be able to do simple tasks, such as eat, swallow and speak.”

For swallowing testing, the children were given sips of water to drink and pudding and pretzels to eat. Repetition of simple sounds and words was also requested. While used differently, the same muscles — perilabial (around the lips) and submental (under the chin) — are in play for both tasks.

Along with how much the muscles are fired, the researchers looked at timing — how quickly do the muscles react, and how long are they being contracted during a task? Swallowing and speech both require very delicate muscular coordination and timing. This biomechanic dance is easy for most but for children with CP, the steps can be arduous.

 “What we saw was that in addition to using more muscle activity, they also used the muscles with less coordination between left and right sides compared to the typically developing group,” Malandraki said. “Our findings show that there may be a muscle coordination issue in some of these children. They can contract the muscles but have a hard time isolating the specific muscles that they need for a specific task.”

Recently published in the Journal of Neurophysiology , the work can inform evaluation processes and improve treatments for the children as they grow and develop.

“We want to better understand what the underlying mechanisms of the speech, feeding and swallowing difficulties that we see in these children are and also what are the interactions between speech and swallowing,” Malandraki said. “We are interested in finding more about a potential cross-system interaction between these two vital functions that both share many of the same mechanisms and muscles in the head and neck but use these muscles a little bit differently — or they’re supposed to use them a little bit differently for each function.”

Brain analysis results next

The study also collected magnetic resonance imaging (MRI) scans of the brains of children with CP and their typically developing peers. Since CP is typically caused by lesions on the brain formed during infancy or even while in the fetal state, this arm of the work is being analyzed now and will reveal neurological understanding of how children with varying levels of CP swallow and speak.

Tackling potentially life-threatening issues for children with CP is a difficult task because no child with the condition is like another. In her work, Malandraki said the severity of CP and of the speech and feeding profiles within the 16 children tested for the recent work ranged widely. Studying data gathered from muscle and brain MRI scans will help understand how some of these children can develop better swallowing and speech skills than others, and give us insights into how children and their families can adapt as the children grow into teenagers and young adults.

“Hopefully we can use these findings to develop treatments that will target these mechanisms,” Malandraki explained. “Most current treatments are not improving their speech and swallowing to the level that hopefully they could if they were based on their underlying mechanisms. Our work is trying to change that.”

Malandraki is currently expanding this work to other neurological populations to guide physiology-based treatment development for debilitating swallowing and speech disorders across the life span.
