Abstract

It has been shown that P300 amplitude is sensitive to self-identity stimuli (e.g., name) and emotional self-evaluation. Participants completed a three-stage auditory discrimination task. The first stage involved a standard tone discrimination task (oddball), the second stage added a secondary mental counting task, and the third stage added a secondary self-evaluation task (participants reflected on whether they were surprised by the occurrence of the target). Results indicated a large increase in P300 amplitude for the third stage compared to the other stages, which suggests that self-evaluation may utilize more cortical resources than non-self-related cognitive-discrimination tasks.
