good one’s own task performance was in the past; higher levels of past performance were accompanied by higher BOLD activity in pgACC. In addition, the relationship between pgACC signal and past performance history was strongest in subjects who relied most on their past performance when predicting their future performance. This suggests that pgACC carries memory traces of past performance and that these guide expectations about how likely we are to succeed in future tasks. In contrast to dorsomedial prefrontal cortex, pgACC activity reflected relatively little information about the social context and the performance of other players, although it is important to note that pgACC activity occurred while the subjects were also concerned with tracking the performance of others in parallel.
