Personality, Relationships, and Hormones Lab

Welcome to the Personality, Relationships and Hormones Lab

Our research is motivated by a desire to understand how important emotional and interpersonal processes, which are typically assumed to apply to all people, may instead differ across people in meaningful ways. We are particularly interested in individual differences in people’s approaches to and experiences in close relationships; how these differences develop and change over time and across the lifespan; and the implications of these differences for interpersonal, dyadic, and physiological outcomes. We approach these issues from an integrative, multidisciplinary perspective, incorporating measures of basic cognitive processes (e.g., attention and memory) and biological markers (e.g., hormones), as well as dyadic and longitudinal data analytic techniques, to address meaningful questions about human behavior.

Current lab projects focus on links between hormones and romantic relationship processes, the physiological and health implications of defensive personality traits such as attachment avoidance and narcissism; and the role of adult attachment in neuroendocrine and psychological responses to intimacy and stress.
