Amygdala tracks the perceptual tuning profiles of untrustworthy individuals. (A) Increasingly similar patterns (derived from PSA) in the left amygdala reveal a neural tuning profile that tracks perceived increases in untrustworthiness. No relationship was found for either the trustworthy or neutral gradients. (B) PSA correlated (Pearson’s r) activation patterns evoked at each morph increment along the generalization gradient to those evoked when initially learning about the original players (separately for each original trustworthy, untrustworthy, and neutral player).
