The hyper-fMRI study of the Trust Game by King-Casas et al. (2005) found that as trust between the two players develops, the activity in the striatum shifts from being based on outcomes to being based on expectations. This was evident in the increased activation of the medial prefrontal cortex, which is associated with mentalizing and processing social information. The study did not find that the extent to which participants learned to trust the other player depended on reputations for generosity or the resting level of activity in the striatum.
