Abstract
People often take either the role of an actor or that of recipient in positive and negative interpersonal events when they interact with others. The present study investigated how the actor-recipient role affected the neural responses to self in emotional situations. Twenty-five participants were scanned while they were presented with positive and negative interpersonal events and were asked to rate the degree to which the actor/the recipient was that kind of person who caused the interpersonal event. Half of the trials were self-relevant events and the other half were other-relevant events. Results showed that people were more likely to isolate self from negative events when they played the role of actor relative to recipient. Pregenual anterior cingulate cortex (pgACC) and posterior dorsal anterior cingulate cortex (pdACC) were more active for self than other only in negative events. More importantly, also in negative interpersonal events, dorsal medial prefrontal cortex (dmPFC) showed greater self-related activations (self-other) when participants played the role of recipient relative to actor, while activities in orbitofrontal cortex (OFC) were greater for self than other only when the evaluation target played the role of recipient. These results showed that the actor-recipient role affected neural responses to self in emotional situations, especially when a recipient role was played in negative situations.Entities:

Figure 1Examples of situation stimuli used in the experiment. Each stimulus included a one-sentence interpersonal event, a question and a 4-point scale. (A) Self-relevant negative interpersonal event and the evaluation target “self” played the role of actor. (B) Self-relevant negative event and the evaluation target “self” played the role of recipient.

Figure 2Brain activities in Target × Valence interaction effect across roles. Activities in pgACC (MNI 16, 48, 8) and pdACC (MNI 6, −18, 42) were greater for self than other only when interpersonal events were negative. Error bars indicated standard errors of mean beta-values. Asterisks indicated that beta-values were greater for self than other(*p < 0.05, **p < 0.001).

Figure 3Brain activities in Target × Valence × Role interaction. Activities in dmPFC (MNI −18, 38, 50) were greater for self than other when the actor or recipient role was played in both positive and negative events. Activities in orbitofrontal cortex (OFC) (MNI −32, 60, 0) were greater for self than other only when the evaluation target played the role of recipient in negative interpersonal events. Error bars indicated standard errors of mean beta-values. Asterisks indicated that beta-values were greater for self than other (*p < 0.05, **p < 0.001).
