| Research Abstract |
In this study, in order to investigate the problem of how grasp positions of objects are selected, we examined grasp positions in the three tasks with different task demands: a vision task (VT), a lift-up task (LT) and a pinch task (PT). We have reported that the grasp positions of the two grasping tasks (the lift-up task and the pinch task) are different in a same object. Especially, we focused on a switching mechanism of grasp points by each task-demand, visual mechanisms that are contributed in grasp point selection, a relationship between grasp point selection and skillfulness of grasping, and a relationship between grasp point selection and fixation points during task execution. As a result, we ascertained that the dorsal vision stream in the human brain contributes the grasp point selection of LT and the ventral vision stream contributes the grasp point selection of VT and PT. Thus, those results indicate a plausibility of our hypothesis.
