Julie Longua Peterson is an Associate Professor of Psychology and an affiliated faculty in the Women's and Gender Studies Program.  Dr. Peterson is also the principal investigator of the Self and Close Relationships Lab.  Her program of research investigates the ways in which explicit (conscious, controlled) and implicit (unconscious, automatic) self and relationship processes influence how people navigate positive and negative interpersonal events (e.g., acceptance, rejection, discrimination). Her research uses experimental, observational, and experience sampling methodologies to explore these themes.  Julie's courses include Introduction to Psychology, Social Psychology, Research Methods, Introduction to Women's and Gender Studies, and a seminar in the Social Self.

Research interests

My research focuses on both self-regulatory processes in daily life and how feelings of (in)security influence close relationships. Specifically, I have explored the effects of explicit and implicit self-esteem and narcissism on behavioral response to;romantic relationship conflict, how positive relationship events differentially impact people with high (vs. low) felt security, and how individual differences in self-esteem and attachment style moderate responses to daily events and connection seeking behavior. More recently I have been exploring 1.) how identity threats, such as sexism and heterosexism, impact decision making and relationship closeness; 2.) how perceptions of a partner's self-worth guide relationship regulation processes.
