Abstract: Knowing how other people’s preferences relate to our own is a central aspect of social cognition, yet how the brain performs this perspective taking is unclear. Here, we ask whether the putative role of the hippocampal formation in transforming first person and extra-personal spatial cues during navigation extends to social learning. In our experiment, subjects learn a stranger’s preference for an everyday activity – relative to a personally familiar individual – and subsequently decide how the stranger's preference relates to further familiar people. We observed hippocampal responses during decisions that require precise social judgments. Investigating reference frame sensitive responses, we identified an entorhinal/subicular region responding to finely resolved decisions involving self-comparisons, but more straightforward choices otherwise. Our data highlight a potential hippocampal-entorhinal division of labor that helps assimilate newly learned information about others into our prior beliefs about the prosocial world.
