Building a Cognitive Model of Social Trust Within ACT-R

This paper describes work underway at the Krasnow Institute for Advanced Study on the topic of modeling social trust. We have built and are testing an ACT-R model intended to replicate human participants building and maintaining social trust using an economic investment game. We already have behavioral and fMRI imaging data for subjects which we expect to generate comparable data by having an ACT-R model read the same inputs the humans did and decide whether to trust or not their partner.
