| Abstract(in English) | In recent researches with a computational approach, it is conceivable that forward models have an important role in controlling multi-limb coordination. However, there is no experimental evidence. To examine the possibility of using forward models for multi-limb coordination, the authors investigated grip-load force coupling, which involves multi-limb coodination. This paper addresses several hypotheses for grip-load force coupling when a forward model is used in control of grip force or when it is not. To confirm the hypotheses, learning processes were investigated in which subjects held an object with novel dynamics by thumb and forefinger and performed a point to point movement. Results indicated that the grip-load force coupling in a steady state was recovered sooner than the arm trajectory, suggesting that the forward model should be used in control of grip force. Therefore, it is shown that the forward model is used for control of multi-limb coordination. |
