| Outline of Final Research Achievements |
The purpose of the present study was to investigate the mechanism of cooperation of two systems realizing prediction of visual events (i.e., stimulus-context-based prediction and action-based prediction). By using event-related brain potentials (ERPs) that are measured with electroencephalogram (EEG), it was demonstrated that (1) stimulus-context-based prediction is reflected by the elicitation of visual mismatch negativity and the reduction of P2, (2) action-based prediction is reflected by the elicitation of a posterior negativity and the reduction of P1, (3) stimulus-context-based prediction can be controlled by action-based prediction in a top-down manner, and (4) the mechanism of the top-down control is that action-based prediction temporarily freezes the operation of stimulus-context-based prediction.
