| Outline of Final Research Achievements |
The objective of this study was to identify the effects of attentional resource allocation in children under several dual-task conditions. Tracking speed and tracking predictability were manipulated to vary task difficulty. The P300 amplitude was reduced in the dual-task condition compared to those in the oddball-only condition. The fast tracking speed produced lower tracking accuracy and later RT. However, the tracking speed did not affect the P300. In contrast, the P300 amplitude was smaller when the change in tracking direction was unpredictable than when it was predictable.
