Recent evidence challenges the view that attention acts on the outputs of early filters dedicated to processing motion, color, and orientation. Instead, "proto-objects" specified by shading, depth, direction of lighting, and surface information are thought to provide input to attentional processing. These findings are extended here to the parsing of occlusion-based contours. Multicolored occlusion structures were briefly presented and illusory conjunctions measured. More illusory conjunctions were made to structures in which color was inconsistent with form information, a result that can be explained by a property of the visual system that biases the integration of color to be consistent with form. Results show that this constraint was based on global structural descriptions rather than the local information provided by T-junctions and collinearity. Together, these results offer a new tool for the study of the binding problem in vision.
注意力作用于专门处理运动、颜色和方向的早期过滤器的输出。相反，由阴影、深度、光照方向和表面信息所指定的“原始物体”被认为为注意力处理提供输入。在此，这些发现被扩展到基于遮挡的轮廓解析。简要呈现了多色遮挡结构并测量了错觉性结合。与颜色与形状信息不一致的结构相比，更多的错觉性结合出现在颜色与形状信息一致的结构中，这一结果可以通过视觉系统的一种特性来解释，即该特性使颜色整合偏向于与形状一致。结果表明，这种约束是基于全局结构描述，而非由T型连接和共线性提供的局部信息。这些结果共同为研究视觉中的捆绑问题提供了一种新工具。
