主讲人简介：Dr. Frank Krueger is Professor of Systems Social Neuroscience at the School of Systems Biology at George Mason University. He investigates the psychological functions and the proximate neurobiological mechanisms of social cognition 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.

讲座内容：Our study investigated how trait anxiety levels (high vs. low) influenced trust decisions under gain and loss frames. Two groups of participants with high (n=32) and low (n=34) trait anxiety levels served as trustors in one-shot binary trust games with various anonymous partners acting as trustees. Besides behavioral measures to characterize trust decisions, we collected eye movement and pupil size as physiological measures to describe the temporal pattern of the decision-making process, and event-related potentials as neural measures to understand the associated neural temporal mechanisms. We hypothesized that participants would exhibit higher trust under the loss frame, particularly amplified for participants with high anxiety traits, driven by the principle of avoiding harm to others. We discuss the results for our collected measures, exploring the dynamics of trust decisions at the behavioral, physiological, and neural levels. Our multi-method study approach provides a comprehensive understanding of how anxiety traits and framing impact trust decisions, highlighting the interplay of the underlying behavioral, physiological, and neural indicators.
