Title: The Anatomical Structure of Sex Differences in Trust Propensity
Dissertation Chair: Frank Krueger, PhD (SSB/IPN)
This dissertation explored the neuroanatomical sex differences in trust behavior towards strangers (TP) measured with the trust game by employing voxel-based morphometry and diffusion tensor imaging (DTI). Results indicated males exhibit greater TP than females, correlated with greater gray matter volume in the frontal, parietal, and temporal lobes, linked to mentalizing, self-referencing, and risk-taking behaviors. For females, DTI results demonstrated a positive association between TP and white matter connectivity strength in the left cingulum white-matter tract, linked to greater emotion-processing. These findings underscore the importance of recognizing sex differences in TP's neural underpinnings, affecting interpersonal, financial, and societal dynamics.
