A Flock of Brains: Round-Robin Designs in the Neural Basis of Interpersonal Perception
In the past 20 years, there has been a surge of interest in using neuroimaging to study the biological basis of self and person knowledge. However, typical neuroimaging studies on these topics employ designs in which subjects have to think about a target that is familiar to all participants but interpersonally distant (e.g. a fictional person, celebrity, or former president). In other designs, the target is interpersonally close to individual participants but different for each person in the study (e.g. each participant’s best friend or family member).
