It is still, however, unclear how the FRN reflects the evaluation of outcomes induced by others. We focused on the relationship between self and other, and recorded ERPs during an alternative gambling task performed by two players (participant and virtual player). FRN was elicited not only by the losses of another in a cooperative situation but also by the gains of another in an antagonistic situation. These results indicate that FRN reflects the evaluation on the basis of one's own evaluative criteria, regardless of the monetary outcome for another. © 2008 Lippincott Williams & Wilkins, Inc.
