Zachary Hohman
My research investigates the intersection of two broad domains of social psychology: 1) group processes and intergroup relations, and 2) attitudes and persuasion. Within these domains, I investigate how social groups influence people's self-conception, attitudes, physiology, and biology as they relate to health behaviors. The goal of my research is to integrate basic cognitive processes into social interactive processes, societal processes, individual processes, and internal processes that explain group and individual health behavior.

Within the group process and intergroup relations domain, I am interested in how group-level
constructs are organized in, and influence the development of, people's self-concept.
For example, for one part of my research program, I investigate the motivational underpinnings
of group identification – e.g., why thoughts of death motivate people to identify
with a group. Across six experiments and three publications, I have demonstrated that
thinking about death leads to group identification (and various health outcomes associated
with group identification) because of the uncertainty surrounding death (as predicted
from uncertainty-identity theory) rather than the terror surrounding death (as predicted
by terror management theory).
For attitudes and persuasion, I am interested in how group-level phenomena impact
people's attitude development, attitude change, and behavior. For example, I have
investigated how attitude ambivalence and social norms interact to predict health-related
behavioral intentions and future behaviors. Across three experiments I have been able
to demonstrate that when people are attitudinally ambivalent about a health-related
topic (adolescent marijuana use in one study and college-aged tobacco use in another)
they look to the group (and the norms of that group) in order to know what to think
(what their attitude should be) and how to behave.
Graduate Students
An Le
I am a second-year graduate student in the SITH lab. I completed my Master's degree in Experimental Psychology at Western Illinois University and my Bachelor's degree in International Business at Foreign Trade University in Vietnam. Generally, I am interested in the self: how people perceive themselves and how their self-perceptions influence their thinking and behaviors. Currently, my research focuses on the link between self-uncertainty and extremism. In my free time, I enjoy traveling, exploring new places, and trying and cooking new cuisines.
Ashley Worley
I am a third-year graduate student in the SITH Lab. I received my Bachelor's degree in Psychology from The University of Kansas. My research interests include social identity and predictors of intergroup relations such as intergroup emotions, intergroup threat, and uncertainty. I am also interested in the content and implications of stereotypes and prejudice and political psychology. I enjoy traveling, having a good cup of coffee, watching sporting events, and spending time with my two kids.
Burch Carter
I am a third-year graduate student in the SITH Lab. I received my Bachelor's degree in Psychology and Neuroscience from The University of Texas at Dallas. My research currently focuses on attitudes and attitude change. I am also interested in social identity, and the impact of status, social influence, and social change on intergroup and intragroup relationships. In my free time, I enjoy reading and watching television/movies.
