表征动量的典型运动效应

The typical motion effect on representational momentum

表征动量是指观察者对运动物体的最终位置的记忆沿着物体运动的方向发生偏移的现象.使用现实世界中人们熟悉的物体作为刺激材料,通过3个系列实验,探索个体关于物体典型运动的经验对表征动量的影响.结果发现:1)当刺激物进行前进和后退运动时,所有刺激材料均出现表征动量现象,前移位量不受刺激材料生命属性的影响,即有生命属性刺激、无生命属性刺激和物理刺激的偏移加权均数不存在差异;2)表征动量存在典型方向效应,即相比于倒退运动,前进运动产生的偏移量更大.这说明表征动量在一定程度上具有认知可渗透性.

Representational momentum ( RM) referred to the tendency of observers to "remember"the stop-ping point of an event as being farther along in the direction of motion than it was in reality.The purpose of this study was to examine that representational momentum was cognitively penetrable , which could be affected by knowledge and experience.This study used figure in life as materials and implied motion through three ex-periments.The results showed that:1) When stimulus moved forward and backward , that was, all stimulus occurred representational momentum.However , displacement was not influenced by the life properties of the objects, that was, there was no difference among three stimulus types ( vehicle, animal, and geometric fig-ure );2 ) There was typical-motion effect in representational momentum , that was , the displacement of forward motion was significantly larger than backward motion.Hence, to a certain extent representational momentum was cognitively penetrable.
