Combination of information from the parallel processing of different basic features (color, size, etc.) can be used to guide attention to targets defined by conjunctions of those features. Wolfe et al. (1990) argued that, although it was possible to guide attention to the conjunction of, for instance, color and orientation, it was not possible to guide attention to targets defined by conjunctions of two colors or two orientations. The present experiments demonstrate an exception to this rule. Although it is true that attention cannot be guided to a target that has red and green parts, attention can be guided to an item that can be described as a whole red target with a green part. In Experiments 1 and 2, we illustrate this point. In Experiments 3 and 4, we rule out some simple size-based accounts of this finding. In Experiments 5 and 6, we begin to explore the nature of these first steps toward dividing the visual scene into parts and wholes.
对不同基本特征(颜色、大小等)进行并行处理所获得的信息组合,可用于引导注意力指向由这些特征的结合所定义的目标。沃尔夫等人(1990年)认为,虽然有可能引导注意力指向例如颜色和方向的结合,但不可能引导注意力指向由两种颜色或两种方向的结合所定义的目标。本实验证明了这一规则存在例外情况。虽然确实无法将注意力引导至具有红色和绿色部分的目标,但注意力可以被引导至一个可被描述为带有绿色部分的整体红色目标的项目。在实验1和实验2中,我们阐述了这一点。在实验3和实验4中,我们排除了对这一发现的一些基于简单大小的解释。在实验5和实验6中,我们开始探索这些将视觉场景划分为部分和整体的第一步的本质。
