Outline of Final Research Achievements

The present study investigated the involvement of cognitive information processing in the visuomotor process through the analysis of grasping performances produced to a target figure that induces a size illusion by focusing on the influence of the illusion on the task movement. When the time window from the target recognition to the movement initiation was severe, the illusion affected the grasping movement. When the grasping was performed with a secondary choice reaction task simultaneously for preventing cognitive processing from being involved in the grasping visuomotor process, the illusion effects on the grasping was still observed. These results suggest that the grasping was executed based on cognitive processing depending on task situations. Further study is required to investigate how cortical visual processes, which functions exclusively for recognizing an object and guiding a movement, associate functionally with the execution of visuomotor performances.
