Event-related potentials were recorded to examine the electrophysiologic correlates of the evaluation of possible answers provided during a semantic, a numeric, and a figure inference task. We examined two conditions: the probe stimulus given was what participants initially generated (Correct answer) or it was unexpected and incorrect (Unexpected Incorrect answer). ⋯ The generator of N320 effect was localized near the anterior cingulate cortex. The N320 effect, therefore, reflects an expectation violation while participants performed semantic, numeric, or figure inference task.
