Does the brain use the same mechanism to simulate both our own and other persons' actions? If it does, then one's current posture should influence action simulation for others, depending on whether current and imagined postures differ. To test this prediction, 20 observers sat upright or bent forward while evaluating the reaching range of a model that had been photographed in similar postures. Posture congruency did not influence performance but decisions were faster and more accurate when the simulation required fewer posture changes. These results begin to reveal the processes that transform visual inputs into motor predictions for others. Implications of the present findings for our understanding of the so-called "mirror system" are discussed.
大脑是否使用相同的机制来模拟我们自己和他人的动作？如果是这样，那么一个人当前的姿势应该会影响对他人动作的模拟，这取决于当前姿势和想象中的姿势是否不同。为了验证这一预测，20名观察者在评估以类似姿势拍摄的模型的伸手范围时，要么坐直，要么向前弯腰。姿势一致性并未影响表现，但当模拟所需的姿势变化较少时，决策会更快且更准确。这些结果开始揭示将视觉输入转化为对他人动作预测的过程。本文讨论了这些发现对我们理解所谓“镜像系统”的意义。
