Outline of Final Research Achievements |
The purpose of this research was to investigate the mechanism of the modulation of attentional resource allocation. The first aim was to establish a method that could assess the allocation of attentional resource with high temporal resolution: event-related brain potentials (ERPs) elicited by auditory stimuli unrelated to a current cognitive task (i.e., probes) could be used to evaluate the amount of attentional resource allocated to the task. The experimental results showed that manipulating the time intervals between probes could improve the temporal resolution in evaluating the allocation of attentional resources. The second aim was to investigate the top-down modulation of attentional resource allocation. The experimental results demonstrated that the allocation of attentional resource could be modulated by the prediction of consequences of one’s own action.

Academic Significance and Societal Importance of the Research Achievements |
本研究によって注意資源配分評価技術の時間解像度が向上した結果、注意資源配分を評価可能な作業環境が拡大されることにより、快適で安全な作業環境の構築や、人間に適合したシステムの開発が加速すると期待できる。さらに本研究は、自らの連続的な動作の結果の予測によって注意資源配分調整が行われることを初めて示した。本成果を応用することで、予測と実際の動作結果の一致度、すなわち「モノを思い通りに操作できている感覚」の評価技術の開発が進むと期待できる。
