| Research Abstract |
Temporal change in attentional allocation to the deviant event from the context was examined by the P300 event-related brain potential (ERP) elicited from a visual 3-stimulus oddball tasks. The results show that the change in nontarget P300 amplitude reflects the expectancy and anticipation to the next target, and that the change in scalp distribution of the nontarget P300 amplitude indicates that although the task-irrelevant deviation captured attention at the beginning, it was subsequently treated as task-relevant deviations.
