| Outline of Final Research Achievements |
In this study, we investigated the modulation mechanism of visual representations in a visuomotor coordination using the Boundary Extension phenomenon. The results showed that the perceived boundary position moved outward from the center of the image to a greater extent when the angle of view was narrower, both when the boundary position was judged visually and when the boundary position was judged by pointing to the screen. However, when the boundary position was judged by pointing, the perceived boundary position was judged to be located in a narrower range than when judged visually. These results suggest that the determination of perceptual location relative to the boundary of a visually presented stimulus may not be the result of processing within the visual modality, but rather may occur after integration of multiple modalities.

触覚モダリティからの入力を用いて境界拡張を検討した先行研究では、情景の知覚に際して視覚モダリティからの入力ではなく、複数のモダリティからの情報が利用されていると主張されている。本研究ではさらに、複数モダリティが統合された後には、その視覚表象に基づいて外界にアクセスする際に、出力モダリティに応じて境界位置の調整が行われる可能性を示した。
近年では、スマートフォンやタブレット端末などのように、画面をタッチすることで操作を行う機器が広く用いられている。外界の環境に対する視覚的な判断と運動制御に用いられる表象の乖離を明らかにすることで、これらの機器のより有効な使用方法を提起可能である。
