车轮错觉的离散快照理论

Discrete snapshot theory of continuous wagon wheel illusion

车轮错觉是在日常光照下看连续的周期性运动的刺激时,个体有时会知觉到刺激朝着反方向运动的现象。文章综述了车轮错觉的离散快照理论的相关研究,主要包括:(1)车轮错觉的认知机制,注意的离散加工导致错觉的产生;(2)离散快照理论的支持性证据,包括行为与神经两方面的证据;(3)离散快照理论的挑战。最后剖析了离散快照理论这一解释的片面之处。

The phenomenon of perceived reversed motion while observers view a continuous 袁 periodically moving stimulus is called the 野 continuous Wagon Wheel Illusion冶 or 野 c-WWI冶 . Here we summarized the discrete snapshot theory which explained the occurrence of the c-WWI. The first 袁 the occurrence of the c- WWI was due to the discrete snapshot of attention. The second 袁 both behavioral and neural evidence sup-ported the discrete snapshot theory. The third 袁 motion detector theory was a challenge to the discrete snap-shot theory. Finally, the future direction about discrete snapshot theory was introduced.
