利用flash—lag效应分离视觉掩蔽中客体的物理位置和知觉位置,以探讨掩蔽效应是否基于知觉到的客体位置。实验中掩蔽刺激做圆周运动,到某一位置时,目标刺激短时呈现,要求被试判断目标刺激(缺角菱形)的缺角方向。通过操作目标呈现时二者之间的相对位置,发现当二者物理位置不重合而知觉位置重合时掩蔽效应最大。该结果表明,视觉掩蔽可基于知觉到的客体位置。

To explore whether visual masking effect depends on perceived locations of the target and mask objects, we adopted the ' flash-lag' paradigm to separate physical and perceived locations of the objects. Specifically,the target (a diamond with a missing angle)was presented near to the moving mask briefly. In this case, the mask could be perceptually overlapped on the target when they were physically separated. Ob-servers were asked to report which angle of the target was missing. The results show that the correct rate of target-identification reached the bottom point when the two objects were perceptually overlapped(but not physically overlapped), suggesting that visual masking effect depends on objects' perceived locations.
