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 process, 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

Josh Brown

I am a brand-new graduate student in the SITH lab. I was raised 40 miles south of Salt Lake City, and earned my Bachelor's Degree at Utah Valley University. I'm interested in social identity, uncertainty reduction, intragroup behavior, and social metacognition. I distract myself from school with camping, cooking, film, visual art, and theatre.

I am a fourth year graduate student in the SITH lab. I grew up in the small town of Kennedy Minnesota, completed my Bachelors Degree at Minnesota State University Moorhead, and my Masters Degree at Ball State University. My broad research interests include the areas of social identity, marginalization, risk taking, social exclusion, and prototypicality. Outside of school I enjoy all things outdoors, video games, and brewing beer.

Elizabeth Niedbala

I am a fourth year graduate student in the SITH lab. I am originally from the Chicagoland area and I received my undergraduate degree from Saint Mary's University of Minnesota. My research interests include intergroup violence, extremism, uncertainty, risk-taking, and stress. Current projects of mine are focused on self-sacrifice during group-level retaliation, how ostracism impacts group identification, and the physiological markers of uncertainty. During my free time I enjoy playing sand volleyball and tasting wine.

Hi, my name is Sarah Hirsch! I'm a born and raised Texan from Allen, a city a little north of Dallas. I'm a junior psychology major, with a sociology minor. After graduation, I plan on getting my masters or doctorate in Forensic Psychology. I'm hoping to go somewhere out of state because I love to travel and experience new things! I plan on working closely counseling inmates and their families. I am actively involved in the Lubbock community through a service organization called Miller Girls. When I'm not at school or volunteering, I enjoy going on hikes and watching Netflix!

Jonnie McMaster

My name is Jonnie McMaster and I am a Psychology major with a minor in Addictive Disorders and Recovery Studies. I am from Georgetown, Texas which is where I spent the summer completing an internship at Georgetown Behavioral Health Institute. I knew that working there would either cement my passion for mental health services or show me that I needed to pursue a different path. I fell in love with mental health services and know that this is the field I needed to be in. I hope to one day obtain my doctorate in Clinical Psychology, where hopefully I would be able to work with a broad range of clients. When I'm not busy with school, sorority, and other organizations I love Netflix, my cat Salem, and Tex-Mex.
