本研究探讨是否可以修改向量的物体抓取运动。25名大学生被要求在观看径向光流时做以下四种类型的左手动作之一：（1）用力握住手握柄;（2）握住手握柄;（3）用力握紧拳头;（4）张开手，左手没有任何东西（正常手状态）。参与者的任务是在感知矢量的同时，用右手不断按下按钮。在每次试验后，他们在101分的量表上估计了向量的主观强度。结果表明，强烈抓握手握任务比其他手部动作更能抑制向量。物体抓取运动会削弱矢量。这可能意味着，被抓取物体的存在以及抓取运动本身都可能抑制向量。我们推测这种抑制的机制可能与认知压力、注意力负荷、力量和肌肉紧张以及多感觉和本体感觉相互作用有关。
The present study investigated whether vection could be modified by an object grasping movement. Twenty-five university students were asked to do one of the following four types of left-hand movements while they were viewing a radial optic flow: (1) grasping the hand-gripper strongly; (2) holding the hand-gripper; (3) clenching fist strongly; and (4) open hand without having anything in their left hands (normal hand condition). The participants’ tasks were to keep pressing a button with their right hands while they were perceiving vection. After each trial, they estimated the subjective strength of vection on a 101-point scale. The result showed that the vection was inhibited by strongly grasping the hand-gripper task more than by the other hand movements. Vection could be weakened by the object grasping movement. It might be suggested that vection could be inhibited by the presence of an object being grasped and also by the grasping movement itself. We speculated that the mechanism underlying this inhibition might be related to cognitive pressure, attentional load, power and muscle tonus, and multisensory and proprioception interactions.
