摘要：

This experiment investigated how the control of hand transport and of hand aperture are coordinated in reaching and grasping movements. An electric actuator attached to the subject's right arm delivered mechanical perturbations randomly during a quarter of the experimental trials. A remote, compensatory adjustment of hand aperture followed the immediate, mechanical affects of the perturbation of hand transport. The invariant spatial and temporal characteristics of the response suggest how the two systems may be coordinated during prehension.
