Psychological & Brain Sciences

Dr. Barch's current research is focused on understanding the interplay among cognition, emotion, and brain function to better understand the deficits in behavior and cognition found in illnesses such as schizophrenia and depression. More recently, her work has expanded to include a focus on the mechanisms through which early adversity (e.g., poverty, stress, disparities in access to health care and education) shape early brain development and subsequent risk for mental health challenges.  Dr. Barch’s faculty website can be reacher here.

Dr. Hill’s current research is focused on understanding the benefits of having a sense of purpose across different life domains, including the promotion of health, wealth, and psychological well-being. His recent work has considered whether purposeful individuals may seek out and navigate experiences of diversity differently from others, demonstrating that having a sense of purpose may promote comfort with diverse groups.

Dr. Lai studies how people create, interpret, and maintain social group distinctions. He is particularly interested in implicit biases: automatic or unconscious mental processes that create a gap between what people value (e.g., racial equality) and what people do (e.g., racial discrimination). His research focuses on (1) learning how implicit biases change, (2) understanding the consequences of implicit bias for behavior, and (3) developing interventions to reduce the impact of implicit biases on behavior.

Dr. English's research is focused on better understanding of how emotion regulation operates in daily life across diverse groups and sociocultural contexts. Recently, her work has begun to examine 1. Emotion regulation and communication in the context of intergroup interactions and, 2. The impact of emotion regulation processes on goal pursuit and well-being of first-generation college students and ethnic minorities in educational contexts.

Dr. White's research focuses on developmental trajectories of executive abilities in typically-developing children and children with damage to frontal regions of the brain. A population of particular interest is children with sickle cell disease, who are predominantly of African descent. Strokes occur in approximately 1/3 of children with sickle cell disease, and most of these strokes damage frontal brain regions that subserve executive abilities. In past and ongoing research, we have demonstrated the utility of blood transfusion in preventing the recurrence of stroke and further decline in cognition. Most recently we showed that executive abilities significantly improve soon after blood transfusion in this underserved and understudied population of children. In terms of teaching, I lead the Clinical Psychology Diversity Proseminar for graduate students in our Clinical Psychology Program.

Dr. Wilkins is a social psychologist whose research examines prejudice, stereotyping, and the self. She explores how social change (e.g. racial and gender progress) affects high-status groups’ perceptions of victimization. She also examines how variation in racial and ethnic minorities’ physical appearance shapes stereotyping and identification. The over-arching goal of her work is to understand social inequities in order to minimize their negative effects on individuals, groups and society.

Dr. Oltmanns, the members of his lab, and their collaborators are conducting a longitudinal investigation of trajectory and impact of personality on health in later life.  The original participants in the study are a representative sample of 1,600 residents of the St. Louis metropolitan area who were between the ages of 55 and 64 when they entered the study.  One third of the participants are Black and two thirds are White.  Therefore, this sample provides an opportunity to explore racial health disparities and, more specifically, the psychosocial and biological mechanisms that may be responsible for their origins and maintenance.

Professor Baugh's primary research interest has been the social stratification of linguistic behavior in multicultural and multilingual nations. Initial interest in this area began with quantitative and experimental studies of linguistic variation among African Americans. These studies evolved into applied linguistic research devoted to policy issues in medicine, education, and law. Gradually his analyses expanded to include populations who suffered various forms of linguistic discrimination, including deaf communities, as well as speakers of languages or dialects who lack fluency in the dominant linguistic norms of their respective societies.

Most of Professor Baugh's research is interdisciplinary, drawing extensively upon related work in the fields of anthropology, ethnography, linguistics, and sociology. These experimental investigations are tailored to have practical applications whenever possible. Recently he has conducted studies of linguistic profiling over the telephone, where callers seeking housing or other goods and services face discrimination due to stereotypes about their speech. Very often these discriminatory acts have legal implications in civil and criminal court cases.

In addition to his linguistic research, Professor Baugh directs the African and African American Studies program, which strives to advance distinguished scholarship of and by people of African descent regardless of academic discipline. These administrative duties are collaborative and involve scholars and students across Washington University who work to advance teaching, scholarship, and public service throughout the African Diaspora.
