Can taking the perspective of other people modify our own affective responses to stimuli? To address this question, we examined the neurobiological mechanisms supporting the ability to take another person's perspective and thereby emotionally experience the world as they would. We measured participants' neural activity as they attempted to predict the emotional responses of two individuals that differed in terms of their proneness to experience negative affect. Results showed that behavioral and neural signatures of negative affect (amygdala activity and a distributed multivoxel pattern reflecting affective negativity) simulated the presumed affective state of the target person. Furthermore, the anterior medial prefrontal cortex (mPFC)-a region implicated in mental state inference-exhibited a perspective-dependent pattern of connectivity with the amygdala, and the multivoxel pattern of activity within the mPFC differentiated between the two targets. We discuss the implications of these findings for research on perspective-taking and self-regulation.T he ability to respond adaptively in the face of emotionally challenging situations is essential to mental and physical health. So much so, in fact, that emotion dysregulation is a core feature of virtually every form of psychopathology. Given this, it isn't surprising that the last decade has seen enormous growth in behavioral and brain research asking how we can effectively regulate our emotions. Although this work has made many important advances (1, 2), it has focused almost entirely on cognitive regulatory strategies that involve controlling attention to and/or rethinking the meaning of stimuli and events. As such, this work has completely overlooked the way in which social cognitive processes can be used to regulate our emotions.The use of social cognition to regulate emotion was suggested by classic works in social psychology (3), which noted that by simulating others' perspective on the world we could shape our own experience and behavior. It is exemplified by "(Stanislavski) method actors" who understand a role by attempting to generate within themselves the presumed thoughts and feelings of a character, thereby allowing themselves to go beyond the written words in the script and respond as their character would (4). It is also present in everyday life when we seek guidance with respect to emotional dilemmas by asking ourselves how a friend, family member, mentor or religious figure (e.g., "What would Jesus do?") would respond in that situation.In the current research we asked whether and how taking the perspective of other people can modify our own affective responses to stimuli. For example, by thinking of how someone more brave than ourselves would respond to a situation, we might downregulate negative emotions, decrease aggression, and calm frazzled nerves. Alternatively, by thinking of how someone more sensitive and anxious would respond to the situation, we might enhance vigilance and increase reactivity to threatening situations.To address these possi...
