Postdoctoral Scholars

David Johnson, Ph.D.


David Johnson is a social-cognitive psychologist who employs computational models to study the psychological processes that underlie decisions. He has used this approach to understand decisions where law enforcement have mistakenly shot unarmed civilians. His work in this area currently focuses on how race and dispatch information influence the accuracy of these decisions, as well as the basic cognitive processes that produce them. In the CRL, David is collaborating on a project examining the ability to model dating decisions within a drift diffusion framework.


Graduate Students

Andrew Defever, M.A.


Andrew Defever is currently a fourth-year graduate student in the social/personality program at MSU. He is interested in the investigation of moral judgments, the connection between emotion and morality, and how emotions convey information during the judgment process. Andrew also has interests in applying research methodology to non-academic business domains such as market research, business analytics, and consumer insights.


Jeewon Oh, B.S.

Jeewon Oh is currently a first-year graduate student in the social/personality program at MSU. She is broadly interested in studying close relationships: What makes a relationship a good one? Why are certain people better at perceiving others’ thoughts and feelings, and how does this ability affect our relationships? Jeewon is involved in projects examining obligation and empathy in family and friends.

Visiting Scholars and Friends of the Lab

Manon van Scheppingen, MSc

Manon is a fourth-year grad student at Tilburg University, Netherlands. She is interested in the origins and consequences of continuity and change in personality and close relationships. Her doctoral dissertation  addresses if and how people are selected into the transition to parenthood, and if this life transition triggers changes in personality and romantic relationship satisfaction. In addition, Manon focuses on the consequences of personality, and the effects of personality similarity on well-being in romantic relationships.

Ji Hyun is a doctoral candidate in department of Human Development and Family Studies at Michigan State University. Her research interests are in psychosocial development across the life span in the context of close social relationships (i.e. family, friends, neighborhood, and social networks). Ji Hyun is particularly interested in identifying and modeling interconnected patterns of health behavior and well-being outcomes for long-term married couples. My recent projects looked at various social context including marriage (Marital relationships and sleep quality in older couples), neighborhood (Neighborhood context and depression/sleep problems in older adulthood), and ecological contexts (elder abuse in families and institutions).
