【摘要】 采用Baylis等人和Hulleman等人的顶点高低判断范式,使用黑白线条图、灰度图和红绿彩图为刺激材料,探讨单一物体自遮挡关系及刺激图形颜色对物体知觉的影响。研究结果表明:①当目标顶点位于遮挡成分中时反应被易化,而当目标顶点位于被遮挡成分中时反应被抑制,这表明物体形状加工过程受到物体深度线索(自遮挡关系)的影响;②刺激图形的颜色对物体顶点高低判断加工没有显著影响。更多还原

【Abstract】 The present study aims to investigate how self-occlusion and color influence the object shape perception. The Baylis’ paradigm, in which subjects had to judge which of the two vertices of an object was higher, was applied to this study. The results shows that: a) If the vertices to be selected are in occluding-part of the object, responses are facilitated; while for the vertices in occluded-part, responses are inhibited. It indicates that the processing of shape perception is affected by self-occlusion; and b) Color has no effects on the vertices position judgment task.更多还原
