Social behavior is often shaped by the rich storehouse of biographical information that we hold for other people. During our daily social interactions we rapidly and flexibly retrieve a host of biographical details about individuals in our social network, which often guide our decisions as we navigate complex social interactions. Even abstract traits associated with an individual, such as their political affiliation, can cue a rich cascade of person-specific knowledge. I will discuss research from my laboratory showing that a distributed neural circuit, with a hub in the anterior temporal lobe, allows us to rapidly retrieve person knowledge by coordinating interactions with a distributed network to support the flexible retrieval of person attributes.
