Twin differences in the Minnesota Trust Game relate to neural mechanisms of suspiciousness.

ABSTRACT: Spite sensitivity, or the fear that a person is willing to intentionally take a loss to ensure that another person will as well, may be a key component in understanding persecutory ideation (the belief that others want to harm you). We implemented a co-twin control design to examine potentially causal relationships among persecutory ideation, spite sensitivity, and neural activity and connectivity. Sixty-nine participants (23 monozygotic twin pairs and an additional 23 unpaired monozygotic twins) completed the Minnesota Trust Game-a social decision-making game played asynchronously with an anonymous partner that targets spite sensitivity by varying the incentives of the partner. Participants with more self-reported persecutory ideation (relative to those with lower persecutory ideation) tr
