The Faces and Minds of Psychological Science

Gordon Bower is one of the premier experimental psychologists and learning theorists. Bower’s research focuses on the ways that various cognitive processes – such as imagery, emotion, and reading and language comprehension – relate to memory, learning and reasoning. Bower was one of the first researchers to examine the effects of mood on memory, and his research has greatly contributed to our knowledge of state-dependent memory and learning.  Bower’s service as Chief Scientific Advisor to the NIMH Director and his appointment as leader of an NIMH task force commissioned to review the state of mental health knowledge and research have positively impacted the direction of psychological science. His pioneering work earned him one of the United States’ highest scientific honors, the National Medal of Science. A Past President of the  Association for Psychological Science (APS), Bower is a member of the National Academy of Sciences and a recipient of the Howard Crosby Warren Medal, the Distinguished Scientific Contributions Award, the Wilbur Cross Medal for Distinguished Scientific Contributions, and the APS William James Fellow Award for his lifetime of significant intellectual contributions to the basic science of psychology.

Elizabeth Kensinger's research focuses on how emotions affect the way we remember information. She is interested in understanding how the emotional part of information affects the cognitive and neural processes that we use to remember it. Kensinger studies memory in young adults and how memory changes over time. Her research challenges the common understanding that “memory declines with age,” and shows the complex ways in which memory does and does not change as we get older. In 2010, Kensinger was among the inaugural recipients of the APS Janet Taylor Spence Award for Transformative Early Career Contributions. Q&A with Elizabeth Kensinger

Living and working in a diverse community offers many opportunities, but also many challenges. Jennifer Richeson studies the challenges of navigating diverse environments for both members of dominant groups and members of socially-devalued, minority groups. Using techniques ranging from the examination of nonverbal behavior to the study of brain scans, Richeson and her team have found that most people find it difficult to interact with others across racial boundaries. Indeed, the effort individuals put forth during cross-race interactions, for instance, can leave them cognitively drained. For example, a white individual is likely to perform less well on a puzzle after being interviewed about race-related topics by a black interviewer (and vice versa), suggesting that individuals are devoting considerable mental resources in their attempts to avoid saying and doing “the wrong thing” during the interaction. In addition to studying interracial contact, Richeson is also investigating how racial bias affects health and decision-making, the consequences of managing a stigmatized identity, and intergroup trust. The MacArthur Foundation awarded Richeson with a fellowship in recognition of the creativity and promise of her work.

Unconscious biases toward African Americans still produce major inequities in the criminal justice system. Using statistical analyses, Jennifer Eberhardt has documented how racially coded features, such as a defendant’s skin color and hair texture, influence jurors’ decisions and the sentences that judges hand down. For example, she’s shown that jurors are more likely to recommend the death penalty for defendants whose features are stereotypically “black.” And she’s demonstrated that police officers are more likely to mistakenly identify black faces as criminal compared to white faces. In 2014, Eberhardt’s worked earned her the prestigious “genius” fellowship from the MacArthur Foundation.

Elizabeth Loftus is an internationally recognized expert in the study of human memory, particularly the malleability of memories. Her extensive research shows that memory is highly susceptible to distortion and manipulation, and that people can vividly recall events that never happened. Loftus developed the “Lost in the Mall” technique, or Familial Informant Narrative Procedure, in which a study participant is told about a time the participant got lost in a shopping mall. Even though the event didn’t happen, a significant percentage of participants developed a false memory for the experience. Her research on false memory, the reliability of eyewitness reports, and memories “recovered” through therapy has affected how law enforcement, courts, and psychologists consider eyewitness testimony. She has served as an expert witness or consultant about false memories in hundreds of legal cases, including the McMartin preschool molestation case; the trial of Oliver North; the Rodney King beating; litigation involving Michael Jackson, Martha Stewart, and Scooter Libby; and Bosnian war crimes trials in The Hague. Loftus is a member of the National Academy of Sciences the Royal Society of Edinburgh. Watch Inside the Psychologist's Studio with Elizabeth Loftus.

Using basic neural and computer models, Michael Frank studies how we learn and make decisions. He hopes to shed light on how these pathways lead to more complex cognitive functions, such as working memory and cognitive control. Franks theoretical work has important clinical applications, and may help us understand, for example, how brain disorders such as Parkinsons disease alter cognition. Frank is also analyzing individual differences in cognition, in other words, why we all think in different ways. He uses a variety of techniques, including theoretical modeling, genetic analyses, and electrophysiological studies. In 2010, Frank was among the inaugural recipients of the APS Janet Taylor Spence Award for Transformative Early Career Contributions. Q&A with Michael J. Frank

A half-century ago, psychologists considered the study of love and attraction unworthy of study. But Ellen S. Berscheid helped make the science of love one of the most vibrant areas of inquiry in modern social science. Berscheid and her collaborator Elaine C. Hatfield helped pioneer an empirical approach to understanding different facets of romantic relationships, including physical attraction, relationship satisfaction, sexuality, and emotional intimacy. She has also studied the importance people place on physical attractiveness, not just when searching for romantic partners but also in other interactions. In one classic experiment, she demonstrated the preferential treatment that male subjects showered on women they perceived as sexually appealing. Most recently, Berscheid has examined the influence that physical and social environment has on relationship quality and satisfaction. In 2012, she received the APS William James Fellow Award for her contributions to the basic science of psychology. Watch Berscheid's Award Address with her colleague, Elaine C. Hatfield, at the 24th APS Annual Convention.

Every employer wants to know the secret to employee motivation. Since the 1970s, Gary Latham has been investigating methods to boost employee performance. His primary interests lie in motivation, performance management, and training. Latham has also co-developed the theory of and conducted extensive research on goal setting, as well as ways employers can use goals to effectively increase job performance and job satisfaction. His studies have revealed that employees perform better when they are given specific, challenging goals compared to easy goals or no goals at all. Latham compiled the results from his goal setting studies and other research into a book for managers entitled, Becoming the Evidence-Based Manager: Making the Science of Management Work for You. He is the recipient of the APS James McKeen Cattell Fellow Award for his  lifetime of significant intellectual achievements in applied psychological research and their impact on a critical problem in society at large. Watch Latham’s Award Address at the 23rd APS Annual Convention.

As one of the most influential cognitive psychologists of the 20th century, Jerome S. Bruner changed the public discourse - and policy - regarding education and how children learn. He is one of the founders of the "cognitive revolution" that transformed not only psychology but other fields related to the mind, such as anthropology, neuroscience, and linguistics. Many of his ideas, which may seem intuitive now, ran counter to the prevailing wisdom of the time, primarily his belief that learning is an active process. This principle pervades Bruner's work: he emphasized the value of teaching children fundamental structure over facts, as it empowers them to actively participate in the quest for knowledge. He also controversially argued that any topic, when appropriately framed, can be taught effectively to children at any stage of development. Some of Bruner's most influential cognitive research includes his concept that people use three systems to acquire knowledge: enactive, iconic, and symbolic (which are based on action, images, and language, respectively), as well as his emphasis on the importance of categorization in every facet of cognition, from perception to decision making. He later shifted focus to the larger cultural aspects of learning, such as the influence of social factors on a child's perception and language development. Bruner's current research focuses on the way we form and use narrative constructions of reality, especially in regard to cultural institutions like the law.

In order to effectively communicate with another person, we need to know something about his or her mental state: how they are feeling, what they are thinking, and what motivates them. Jason Mitchell is using brain imaging techniques to study how we function socially, an example of the growing field of social neuroscience. His research has clarified two characteristics of social cognition: first, that social thought is different from other types of thinking, and second, that one of the ways we understand the minds of others is by referring to our own mental state. In 2010, Mitchell was among the inaugural recipients of the APS Janet Taylor Spence Award for Transformative Early Career Contributions. Q&A with Jason Mitchell

Growing up in poor urban neighborhood, Carl Hart watched crack cocaine ravage the lives of his relatives.  Early in his research career, Hart set out to find a neurological cure for chemical addiction. But as he began studying addicts, he found that there was more at issue than the neurochemical properties of the illicit drugs. In groundbreaking experiments, he offered crack addicts a choice between a dose of the drug or a monetary reward.  When the dose was smaller, addicts often chose the money.  When the monetary reward increased, all the participants opted for financial gain over getting high.  A tenured science professor at Columbia University — and the first African-American to hold that distinction — Hart has leveraged his research to advocate for policy reforms. He argues that law enforcers focus too heavily on prosecuting drug users while ignoring poverty, racism, and other socioeconomic conditions that spur substance abuse and crime.

Daphna Shohamy researches learning, memory and decision making. Specifically, she tries to understand the underlying brain mechanisms of how we learn from experience and how we use what we learn to guide decisions and actions. She adopts an integrative approach that draws broadly on neuroscience to make predictions about cognition.  Her research provides a deeper understanding of the cognitive and neural processes involved for different aspects of behavior. In 2011, Shohamy received a Janet Taylor Spence Award for Transformative Early Career Contributions from the Association for Psychological Science (APS). Q&A with Daphna Shohamy

In her research on early cognitive development, Judy Deloache examines how young children come to understand the various types of symbolic representations around them. Her research on infants and young childrens understandings of pictures, models, and replica objects shows that they have difficulty understanding the relation between a symbolic object and what it stands for. Failing to achieve what she refers to as dual representation, infants and toddlers often treat symbolic objects as if they were real, trying, for example, to lift a picture of an object off the page on which it appears. She recently documented a new phenomenon called scale errors, in which young children treat a miniature object as though it were its much larger counterpart, trying, for example, to sit in a tiny chair or get into a miniature car. DeLoache is a recipient of a special 25th anniversary APS William James Fellow Award for her significant intellectual contributions to the basic science of psychology.

Michael Gazzaniga, a Past President of the Association for Psychological Science (APS), is widely considered to be one of the fathers of the field of cognitive neuroscience, founding the Journal of Cognitive Neuroscience, the Cognitive Neuroscience Society, and serving as Editor-in-Chief of The Cognitive Neurosciences – considered to be the sourcebook for that field. He is credited with being the first researcher to examine split brain patients in order to understand whether some cognitive functions are predominantly performed in one brain hemisphere or the other. Gazzaniga’s examination of split brain patients and his contributions to the field have greatly enhanced our understanding of lateralization of cognitive function within the brain, and how the two brain hemispheres communicate. Gazzaniga is a member of the National Academy of Sciences a fellow of the American Academy of Arts and Sciences, the Institute of Medicine, and the American Association for the Advancement of Science. Watch Inside the Psychologist’s Studio with Michael Gazzaniga. Watch Gazzaniga's Keynote Address at the 25th APS Annual Convention.

How exactly do we learn to speak? Patricia Kuhl has spent her career developing answers to that question. Kuhl is internationally recognized for her research on early language and brain development, and for her studies that show how young children learn. She is co-director, with her husband Andrew Meltzoff, of the University of Washington’s Institute for Learning & Brain Sciences. Kuhl’s lab investigates how infant and adult brains process speech. She has also conducted research on language development in autism. Kuhl is widely known for her theories that account for the developmental change by which infants’ ability to discriminate speech sounds becomes increasingly specific to their native language as they age. This model shows that babies use their computational abilities to “crack” the speech code and that their social skills play an important role in learning. Her research has played a major role in identifying critical periods in development. Kuhl is a recipient of a 25th anniversary APS William James Fellow Award  for her significant intellectual contributions to the basic science of psychology. Read more about Kuhl’s research here.

  Traumatic stress not only affects our brains, but can also strike us at the cellular level. Iris-Tatjana Kolassa explores the biological, particularly the molecular, changes that occur after situations of extreme stress. She is also studying whether therapeutic interventions can reverse such alterations. Kolassa’s work has been of increasing influence on an international scale as it signals a paradigmatic breakthrough, creating the scientific sub-discipline of “molecular psychology,” which employs molecular biology for the advancement of psychological science. It uniquely demonstrates how molecular methods may be incorporated into the system sciences of clinical psychology and behavioral neuroscience. Additionally, she investigates genetic risk factors that contribute to the development of a fear network in which memories of traumatic events are stored.  As part of her work, she collaborates intensively with partners from molecular biology, molecular toxicology, immunology, genetics, and molecular medicine. She is the recipient of an APS Janet Taylor Spence Award for Transformative Early Career Contributions. Q&A with Iris-Tatjana Kolassa  

Humans are very emotional creatures. James Coan studies how our emotions are shaped by our social relationships. In particular, he is interested in how we use various emotional behaviors–such as facial expressions and verbal communication–to adjust our emotions, as well as the emotions of others. Coan is testing the theory that when we are alone, tasks we have to perform may seem more difficult and appear to take up more of our resources than when we are in the company of others. This “social baseline theory” suggests that human social interactions have evolved as a way to help us conserve energy. Coan's innovative work (integrating many disciplines and using multiple methodologies) will shape how research will be done for many years to come. In 2010, Coan was among the inaugural recipients of the APS Janet Taylor Spence Award for Transformative Early Career Contributions. Q&A with James Coan

Considered one of the world’s most influential cognitive psychologists, Anne Treisman developed a classic psychological model of human visual attention. The feature integration theory of attention proposes a two-stage model for our perception of objects. The pre-attentive phase occurs automatically, before conscious awareness. In this stage, her research suggests, we register the elementary features of a visual stimulus, before our minds have grouped those features or bound them to an object. In the second phase, called the focused attention stage, we combine the features to perceive the specific object. Treisman’s work has formed the basis for thousands of experiments in vision, cognitive, and neurological sciences. Her pioneering research on attention led President Barack Obama to award her the National Medal of Science.

Would you believe a child witness? When Gail Goodman first posed this question in 1981, she found that most judges and juries didn’t have an answer, so she conducted much of the early research in the now robust fields of child memory and children as eyewitnesses. She showed that many children are quite capable of accurately recounting witnessed events, but that their accuracy is strongly affected by factors like the type of questions asked and the amount of intimidation or comfort the child experiences while being interviewed. She has also studied the emotional effects of testifying on a child, and has found that many children who have testified in a legal setting showed improvements in emotional well-being over time comparable to that for child victims who did not testify. For other children, special protections in court are likely needed. Goodman is a recipient of the APS James McKeen Cattell Fellow Award for her lifetime of significant intellectual achievements in applied psychological research and impact on a critical problem in society at large. Watch Goodman’s Award Address at the 24th APS Annual Convention.

How do people regulate their social behavior, especially when unconscious prejudices and stereotypes threaten to bias our responses? David Amodio studies the mechanisms of self-regulation by integrating ideas and methods from social psychology, neuroscience, and psychophysiology. His research has elucidated the sources of implicit bias, rooted in separate systems for learning and memory, as well as the interacting neurocognitive mechanisms involved in the control of social responses. This work has led to a better understanding of why self-regulation sometimes fails and why some people are better at self-regulation than others. It has also informed basic theories of cognitive neuroscience regarding the way that goals and motivations shape cognitive and perceptual mechanisms of response control. In 2010, Amodio was among the inaugural recipients of the APS Janet Taylor Spence Award for Transformative Early Career Contributions. Q&A with David Amodio

People tend to proceed through life trying to act their age. But the pioneering research of Ellen Langer suggests that adopting the attitude of a younger person may actually have health benefits. In a classic 1981 study, she had old men live in a retreat that was retrofitted to look like 1959, while they pretended that they were living in that year. She and her colleagues found that the men experienced improvements in vision, strength, and other abilities, and that they actually looked younger as well. Langer’s mind-body research indicates that just as social cues can make us feel old, other social cues can make us feel and act young.

Throughout his career Steele has been interested in processes of self-evaluation, in particular in how people cope with threatening self-images. This work has led to a general theory of self-affirmation processes. A second interest, growing out of the first, is a theory of how group stereotypes—such as stereotypes about African Americans in academic domains and women in quantitative domains—can influence intellectual performance and academic identities. Third, he has investigated addictive behaviors, particularly alcohol addiction, where his work with several colleagues has led to a theory of “alcohol myopia,” in which many of alcohol's social and stress-reducing effects are explained as a consequence of its narrowing of perceptual and cognitive functioning. Steele is a recipient of the Association for Psychological Science (APS) William James Fellow Award for his lifetime of significant intellectual achievements to the basic science of psychology. Watch Inside the Psychologist’s Studio with Claude Steele and Elizabeth Phelps.

Cognitive neuroscientists study people at two explanatory levels: the brain and behavior. Using psychometric models and brain imaging tools, Rogier Kievit explores how theoretical psychology, neuroscience, and philosophy of mind can be used to understand the links between the brain and behavior. His current research relates brain function and structure (using MRI) and cognition in aging populations using structural equation models and network analysis. With the goal of increasing health in older populations, Kievit’s particular interests are in models that effectively capture how cognitive changes across lifetime relate to brain reorganization, adaptation and compensation.

Evaluation is something people do every day, whether they are assessing their to-do list or forming opinions about a book they’re reading. William Cunningham is investigating how evaluating other people or objects leads to emotional responses. Through a combination of social psychological and cognitive neuroscience techniques, Cunningham has found that affective states (in other words, emotional states) are built moment to moment by multiple processes that link together relevant information about the person’s environment with their own personal attitudes. He has studied these processes in various constructs including the study of prejudice, decision-making, political attitudes, morality and emotional development in children. Through his work, Cunningham is hoping to build a more complete picture of the processes behind emotion. His groundbreaking research made him one of the 2011 recipients of the Janet Taylor Spence Award for Transformative Early Career Contributions from the Association for Psychological Science (APS). Q&A with William A. Cunningham

When social groups interact, notions of “insiders” and “outsiders” develop. Using a variety of approaches – psychological, physiological, and neurobiological – Valerie Purdie-Vaughns seeks to understand relationships between social groups and reduce intergroup bias and conflict. In particular, she investigates how minority and majority groups interact, focusing on experiments that closely mirror real-world scenarios. For instance, several recent studies have examined how the anxiety of feeling stigmatized can lead to dysregulated eating and psychological distress. By linking neuroendocrine and stress biomarkers to contextual features of real-world settings, Purdie-Vaughns is able to understand the interaction between physiological mechanisms and environmental factors underlying stigmatization and group relations.  Linking biology to social contexts allows her to better design effective solutions to social problems.

Poor people are the subject of many negative stereotypes, including the assumption that they are inherently incapable of making sound financial decisions. But APS Fellow Eldar Shafir has demonstrated that the cognitive load and bandwidth limitations imposed by living with scarcity can lead to bad financial choices that often trap people in a cycle of poverty. Shafir studies decision making, judgment, and behavioral economics. His recent research has focused on decision making in contexts of poverty and on the application of behavioral research to policy. In various experiments, Shafir and his colleagues have shown that, when faced with financial stress (but not otherwise), poor people fare worse on cognitive tasks than well-off people. His work shows that juggling a life of poverty consumes mental resources, which can distort decision making in ways that exacerbate poor behaviors under financial hardship.

The work day can often be somewhat predictable and routine, but Christina E. Shalley is attempting to enhance the creativity of employees. Shalleys research focuses on how a variety of social and contextual factors affect individuals and teams creativity. Her research combines psychology and management, using a variety of survey and experimental techniques. Specifically, she is investigating how to make jobs and work environments more conducive for creativity. Shalley has also studied group behavior and found that having a lot of personal ties and a diverse social network makes individuals more creative when they are working with others, increasing the teams overall creativity.

We make decisions all the time and often in uncertain circumstances. Elke Webers research focuses on how we judge those choices, the decisions we end up making, and individual and cultural differences in risk-taking. Specifically, her research examines behavioral models of decision making and how to measure and model risk-taking behavior. Her work has tied together psychology and economics, by examining risky financial decision making. Additionally, she studies environmental decision making, for example, how people respond to climate change and ways in which policymakers can present programs to the public to make them most effective.

For advice on love, you’re probably better off going to Elaine Hatfield than Dr. Drew.  In her more than 40 years of research, Hatfield has taken an empirical approach to understanding different facets of romantic relationships, including physical attraction, relationship satisfaction, sexuality, and emotional intimacy. She pioneered the theory that there exist two types of romantic love, passionate and companionate. Though intense, irrational passionate love differs greatly from deeply affectionate and stable companionate love, Hatfield has found that both have an impact on relationship satisfaction and longevity. She also designed the Passionate Love Scale to quantify components of passionate romance; today this scale is used everywhere from psychology labs to online dating sites. Her research extends beyond romantic relationships, however; she has also studied extensively the idea of equity, or fairness, in social contexts, as well as the influence of gender on sexual motivation and behavior. Hatfield is a recipient of the Association for Psychological Science (APS) William James Fellow Award for her  lifetime of significant intellectual contributions to the basic science of psychology. Watch Hatfield’s Award Address at the 24th APS Annual Convention (introduction by Ellen Berscheid).

Autism was once thought to be the result of detached parenting rather than a condition of the brain. Internationally renowned developmental psychologist Uta Frith was among the first scientists to debunk that myth. Frith found that autistic people have trouble understanding mental states and find it hard to intuit what others may be thinking. She has also suggested that individuals with autism are highly capable of processing details but worse than other individuals at integrating information from many sources. And Frith has been a major force in destigmatizing dyslexia, showing it to be separate from environment and intelligence. Frith is the recipient of an APS 25th anniversary William James Fellow Award for her significant intellectual contributions to the basic science of psychology.

Research has documented that Americans with more money and education have improved health prospects compared to poorer people. Nancy Adler has been a pioneer in investigating how social, psychological, and biological factors associated with socioeconomic status (SES) act together to determine the onset and progression of disease. Adler has investigated why individuals engage in health-damaging behaviors and how their understanding of risk affects their choices. This research has primarily been in reproductive health, examining adolescent decision making regarding contraception, conscious and preconscious motivation for pregnancy, and perceptions of risk of sexually transmitted diseases. She also examines subjective perceptions of one’s own socioeconomic status and how these perceptions relate to health along with objective indicators. Her work has raised the study of health disparities all over the globe to a new level of sophistication. Adler is the recipient of a special 25th anniversary APS James McKeen Cattell Fellow Award for her significant intellectual achievements in applied psychological research and their impact on a critical problem in society at large.

Everywhere we turn these days, we are confronted with a dizzying array of choices, whether we’re shopping at the supermarket or searching for a first home. Barry Schwartz’s research investigates the decision-making processes that underlie our choices and examines how our choices make us feel. Schwartz’s research has shown that, rather than making us feel better, having more freedom and choice often makes us feel worse. Specifically, the expectation of choice may cause us to question our choices before we make them and can lead us to be disappointed with them afterward. More recently, Schwartz has turned to examine the role of ‘practical wisdom’ – built on personal experience, ethics, and judgment – in decision-making. Throughout his work, Schwartz blends insights from psychological science and economics to understand how we make decisions, how we come to value some things above others, and how we balance our sense of morality with our own self-interest. Schwartz is the author of several best-selling books, including The Paradox of Choice: Why More Is Less and Practical Wisdom: The Right Way to Do the Right Thing. Watch Schwartz’s Bring the Family Address at the 24th APS Annual Convention.

Ed Diener has focused his career on uncovering the essential ingredients to subjective well-being, a term that includes positive feelings and life satisfaction. Nicknamed “Dr. Happiness,” Diener developed the Satisfaction with Life Scale and other measures of psychological well-being. In one noteworthy study, conducted with Martin E.P. Seligman, he found that students with the highest levels of happiness and fewest signs of depression had strong ties to friends and family. Another important finding is that there are some universals in what predicts happiness around the globe, such as trust and respect, but there are also some culture-specific causes as well. For example, self-esteem is more predictive of subjective well-being in individualistic cultures, and religiosity is more predictive of life satisfaction in highly religious societies. According to Diener’s research, even the majority of disadvantaged people, including those with disabilities, report greater-than-neutral levels of happiness. A new direction in Diener’s research is examining the outcomes of subjective well-being, and he has found that in general it leads to better health and social relationships, to greater work productivity, and to better citizenship. His empirical examination of happiness has contributed enormously to the understanding of human well-being. Diener is the recipient of a 25th anniversary APS William James Fellow Award for his significant intellectual contributions to the basic science of psychology.

The famous Bobo doll experiment showed that children learn through observation, not just through reward and punishment. In that classic study, Albert Bandura showed that children who had watched adults beat an inflatable clown doll learned to model the same aggressive behavior. This study marked an important shift in the field of psychology toward a social–cognitive model of learning. For almost 60 years, Bandura’s work in the fields of social and cognitive psychology has served as a foundation for research on topics ranging from moral judgment to the effects of media violence. Considered one of the most influential psychological scientists of all time, Bandura is a recipient of the APS James McKeen Cattell Fellow Award for his achievements in applied psychological research. Watch Inside the Psychologist’s Studio with Albert Bandura and Gian Vittorio Caprara.

How do we acquire language and what is the cognitive architecture involved in written or spoken language processing? What are the general learning mechanisms allowing us to extract the statistical regularities of the world? How do these mechanisms structure our conscious states? Through his research, Arnaud Rey addresses these questions by testing and refining computational models of cognition and language processing. But, beyond these easy problems (that humans will certainly solve sooner or later), he is interested in understanding how human language has emerged throughout evolution.

Over the course of one’s life, hormonal changes alter behavior, mood, and cognition. Bruce McEwen has spent more than 40 years studying how hormones regulate the brain and nervous system, and his lab helped draw distinctions between the vital and toxic forms of stress. McEwen coined the term allostatic load, a concept that explains how stress systems that help the body survive can cause problems when overworked. This work has led to a realization that stress hormone effects are protective in the short term and potentially damaging in the long term.

After being assigned to an academic externship at a unit in a London psychiatric hospital where violent and self-injurious patients were treated, Matthew Nock became interested in the question of why people intentionally harm themselves. Ever since that experience, Nock has pursued research to deepen scientific understanding of suicide and self-injury. His studies have approached self-injury behaviors from multiple angles to better understand how such behaviors develop, can be predicted, and prevented. Nock collaborated with Mahzarin Banaji to adapt the Implicit Association Test (IAT) to measure suicidal thoughts in teenagers.

Jeansok Kim investigates how stress influences behavior. His work has shown that stress likely affects learning and memory by changing electrical activity in a section of the brain called the hippocampus. Research in Kim’s lab has also revealed that these electrical changes are mediated by N-methyl-D-aspartate (NMDA) receptors that are found in the brain. Kim’s laboratory also uses behavioral animal models to test what forms of learning are affected by stress and to study the processes that allow animals to learn. He is the recipient of a James McKeen Cattell Fund Fellowship.

Carol S. Dweck's empirical work has revealed that when we see ourselves as possessing fixed attributes, we blind ourselves to our potential for growth and prematurely give up on engaging in constructive, self-improving behaviors. In contrast, seeing the self as a developmental work in progress can lead to the acquisition of new skills and capabilities. This theoretical framework has been used to address a variety of societal concerns, such as achievement gaps between ethnic or gender groups. Dweck finds that victims of negative stereotypes who have (or are taught to adopt) a growth mindset can then take a more mastery-oriented stance to achieve their goals even in unfavorable learning environments. As a result, they can often excel despite the obstacles they face. The impact of Dweck's work has spread to other domains beside academic achievement - including willpower, conflict resolution in the Middle East, racial prejudice, and adolescent aggression. Her rigorous research has been applied extensively in schools and organizations to empower children and adults around the world, and she is a recipient of an APS 25th anniversary James McKeen Cattell Fellow Award for bridging disparate fields of developmental, social, and personality psychology.

Shelley E. Taylors research explores our ability to perceive some stressful situations in ways that have both psychological and biological benefits. Taylors research shows that in some circumstances, we can develop “positive illusions” – such as an illusion of personal control or unrealistic optimism about the future – to handle stressful situations. Taylors tend-and-befriend model illustrates how people, especially women, will come together support one another in stressful situations. Her lab is examining the genetic, early environmental, and neurocognitive origins of these coping mechanisms and their benefits. Taylor is a recipient of the Association for Psychological Science (APS) William James Fellow Award for her lifetime of significant intellectual achievements to the basic science of psychology.

Are wars, rivalries, and other conflicts an inevitable part of intergroup relations? Marilynn Brewer says no. Internationally recognized for her research on social identity, collective decision making, prejudice, and intergroup relations, Brewer showed that people attach themselves to a group not because of ill feelings toward other groups, but because they simply are looking for a place of trust and security. Brewer is particularly recognized for her theory of optimal distinctiveness, based on the idea that the conflicting costs and benefits of sustaining an optimal group size would have shaped social motives at the individual level. The theory posited that we have distinct, and opposing, drives to belong to groups and to assert our individuality. As we feel more included in a group, our need to differentiate ourselves becomes more salient. This motivates us to identify with distinctive groups that can satisfy both needs simultaneously. Brewer is an APS Past President and recipient of a special 25th anniversary APS William James Fellow Award for her lifetime of significant intellectual contributions to the basic science of psychology.

John Weisz uses psychological science to help children and adolescents overcome emotional and behavioral problems—including depression, anxiety, and misconduct.  Following his Deployment-Focused Model of intervention development and testing, Weisz uses randomized controlled trials and meta-analyses to identify interventions that will succeed in the community clinic and school settings where young people most often receive mental health care. Through his Harvard Lab for Youth Mental Health, Weisz and his team carry out multiple projects with a network of collaborators, including researchers from diverse disciplines, policymakers and government leaders, clinic and school personnel, and the true experts: families who use the mental health care system. Weisz is the recipient of a 25th anniversary APS James McKeen Cattell Fellow Award for bringing science and practice together to improve youth mental health care.

Emotions like anger, sadness, and fear have traditionally been thought of as innate, discrete entities, each with its own biological core: An event (seeing a snake) triggers a particular hardwired emotion (fear) and its corresponding behavioral and physiological responses (an adrenaline surge, screaming, running away). As Lisa Feldman Barrett has found, however, this view is not well supported by the scientific literature, and so she has developed a model that is more in line with the data. The Conceptual Act Model conceives of emotions not as the basic building blocks of the mind, but as complex perceptions, built from four basic systems – core affect, conceptualization, executive control, and language. Different emotions (e.g., the unpleasant fear of threat, the pleasant fear on a rollercoaster) are produced by combining these systems in different ways, the way that subatomic particles create atoms and molecules. Barrett is now focused on empirically validating this model using psychological and neuroscience techniques and achieving a deeper understanding of how the brain integrates our core affective and conceptual systems to form emotional constructions.

Peter Ayton studies our judgment and decision making processes, especially where those processes often go wrong. He has investigated judgment errors like the hot-hand fallacy, in which people tend to expect that recent positive successes within a random sequence will continue—like a basketball player on a “hot” shooting streak—and the related gambler’s fallacy, in which people expect that such a positive or negative streak will eventually be balanced out. Ayton has also examined the ways in which these fallacies can harm us, such as the increase in bicyclist deaths in the aftermath of the 2005 London underground bombing, as fear caused many people to abandon the subway in favor of cycling—statistically a much more dangerous mode of transportation. His research has helped bring to light our judgment errors in all aspects of modern life, including sports, health, and computing.

Paul Ekman studies facial expressions and the way they can signal deception and reflect a person’s true underlying emotion. Ekman’s research was the first to show that some types of facial expressions (such as fear, disgust, and anger) are universal among all cultures; and along with Wallace V. Friesen he developed the widely used Facial Action Coding System – a taxonomy of every facial expression. His research on identifying deception and hidden demeanor is used by law enforcement and national security organizations to help identify security threats. Ekman was named one of TIME magazine’s 100 most influential people, one of APA’s most influential psychologists of the 20th century, and was the inspiration for the main character, Cal Lightman, on the TV show “Lie to Me.” Ekman has even consulted with the animation studio Pixar to help bring their characters to life. He is the recipient of the Association for Psychological Science (APS) William James Fellow Award for his lifetime of significant intellectual contributions to the basic science of psychology.

Henry L. “Roddy” Roediger, III has spent a career studying human learning and memory, particularly processes of memory retrieval. His recent research has focused on the power of retrieval as a mechanism for improving learning and retention and in applying this work to educational settings. His research has demonstrated that students retain more material when they retrieve it via tests than from restudying it, and Roediger and his collaborators are conducting field studies to determine whether their test-enhanced learning intervention is effective under actual classroom conditions. (It is). Roediger is also interested in illusions of memory. Through his investigation of false memories, Roediger and his team have demonstrated that people can incorporate aspects of present events into their memories, leading to very vivid — but untrue — memories. Roediger has also studied how false memories can be created by remembering in groups and how older adults generally show a greater propensity to false memories. His research includes the development of the Deese-Roediger-McDermott paradigm, which demonstrates that when people are given a list of words strongly related to a central (but not presented) word, there is a high probability of falsely remembering the associated word that was not presented. Roediger’s earlier research was concerned with implicit memory, or how past experience can be expressed in ongoing behavior with little or no awareness of memory processes being involved; with hypermnesia (how memories can be recovered over time without intervening study); and with how retrieval of some information can impair retrieval of other information (a process now referred to as retrieval induced forgetting). Roediger is a Past President of the Association for Psychological Science (APS). He is a recipient of the Association for Psychological Science (APS) William James Fellow Award for his lifetime of significant intellectual achievements to the basic science of psychology. See http://psych.wustl.edu/memory/ for more information.

One of the biggest challenges psychotherapists face is deciding on the appropriate treatment for individual patients. Wolfgang Lutz is an internationally recognized researcher on psychotherapy, and is leading the field in collecting important data about treatment effectiveness and results. He has pioneered the concept of expected treatment response (ETR), which involves an individualized log of each patient’s progress in relation to their expected response to the therapy. His work is helping providers to deliver proven and individually tailored treatment plans and to pre-emptively spot patients at risk for treatment failure.

In scientific experiments as in architecture, it’s all about design. Patrick Onghena studies methodology and statistics in order to help other investigators properly set up their studies and analyze their results. He is especially interested in optimizing single-case experimental design so that researchers can glean as much reliable information as possible from small data sets. His recommendations have influenced the field of methodology and have been used in several studies on pain, depression, chronic fatigue, language pathology, learning disorders, relational aggression, and education. Onghena’s other area of expertise is meta-analysis, an increasingly vital tool for examining large volumes of data from many different studies that all address similar hypotheses. He has applied his meta-analytical skills to replicated single-case experiments and to a range of questions, like the possible pain-relieving effect of antidepressants and the effect of early prevention programs for families with young children at risk for physical child abuse and neglect.

Gabriella Vigliocco investigates how our brains integrate language and cognition, examining a variety of languages, both spoken and signed, and using tools from several disciplines, including neuroscience and experimental psychology. Over the years, her work has contributed to our understanding of how we represent meaning, how cognition shapes languages and how language shapes cognition. She has challenged many traditional ideas about language, like the notion that language is a modular and purely symbolic system that does not entail direct links with our sensory-motor and affective experience. She has developed theoretical and computational models of how meaning is represented and how sentences are produced that account for language performance in terms of interactions among different types of linguistic and non-linguistic information. She is now using these models to tackle questions like how abstract concepts such as justice and courage are formed and processed in our brains.

Understanding behavior through Mathematical Modeling has been used to simulate everything from climate patterns to population growth, but Dirk Helbing uses them to examine something even more complex, namely human behavior. Drawing on his background in physics, Helbing developed the “social force model” to simulate the movement of pedestrians, whose behavior can depend on variables such as desired velocity and the distance between a pedestrian and other people or objects. He has also used mathematical methods to study a variety of behaviors including cooperation, social norms, conflicts, and revolutions, traffic flows, and the self-organization of groups.  Helbing is currently leading an ambitious project called FuturICT with its Living Earth Simulator, a computer simulation that aims to model life on Earth, with a focus on techno-socio-economic systems. He hopes to one day use this computer-modeled world to understand current global economic and societal activity, and prevent or mitigate crises.
