| Abstract(in English) | The human solves redundancy problems involved in a motor task, and performs the task. In this study, we focused on how the human deals with the redundancy problem of target in reaching movements. We considered the reaching movements in horizontal plane, and we specified the following two task conditions: the target with redundancy, in which one-dimensional visual information of reaching target and hand position of subject was provided, and the target without redundancy, in which two-dimensional information was provided. In these conditions, observation of same motor outputs suggests that the human explicitly solves the target redundancy problem, and vice versa. We controlled movement kinematics, and measured hand impedance at movement end. Results of measurement experiments showed that the hand viscoelasticities in the task using the target with redundancy were significantly smaller than those using the target without redundancy even under the condition in which the movement kinematics was controlled. These results indicate that the human adjusts hand impedance depending on target redundancy, and suggest that the human plans and executes movements by utilizing information of target redundancy rather than explicitly solving the target redundancy problem. |
