【摘要】 以往有关视觉完形加工的研究主要探索同一深度平面内的相似纹理表面或相关轮廓特性等对完形加工的影响。该研究采用汉字碎块 ,考察了双眼视差、颜色以及遮挡等线索在视觉完形中的作用。发现结果如下 :视差与颜色等线索阻碍了视觉完形加工 ;遮挡线索加速了整体的视觉完形形成 ;在高级认知加工参与下 ,遮挡线索有效抑制了视差、颜色等线索的分离作用。通过对知觉填补机制及其理论的讨论 ,可以认为 ,该研究的结果为不同深度平面间的视知觉完形加工提供了实验支持。更多还原

【Abstract】 Visual completion is constantly used by the visual system to deal with image data that is missing, ambiguous or corrupted. In recent years, there have been a large number of researches on visual completion. Although many researches reported that visual completion is based on Gestalt law in a common depth surface, little is known about the visual completion process among different depth surfaces. In this study fragments of Chinese characters were used to investigate the effects of binocular disparity, color and occlusion in visual completion. The results indicated that binocular disparity and color hinder the visual completion process. Occlusion facilitates global visual integration, and that global visual integration may inhibit those separation effects when high-level perceptual processing is involved under such occlusion conditions.更多还原
