The Social Cognition and Interaction: Functionality and Immersion (SCI:FI) LAB investigates the psychological functions (i.e., why they exist and work) and the proximate neurobiological mechanisms (i.e., how they work) of social cognition (e.g., beliefs, schemata) in social interactions (e.g., trust, cooperation, altruistic punishment). By combining paradigms from social psychology and experimental economics with methods from social and computational neuroscience, the lab pursues the following three lines of research: The first line of research seeks to advance understanding of the neuropsychological underpinnings of social beliefs (e.g., moral, religious, and free will beliefs). The second line aims to understand the neural correlates of interpersonal trust in social dyads. The third line is designed to shed light on the neural signatures of altruistic punishment of social norm violations. With such interdisciplinary and multi-methods approach, the lab aims to promote the transfer of basic research findings into treatment for and prevention of social brain disorders ultimately providing benefits to human health.
