A visual search experiment using synthetic three-dimensional objects is reported. The target shared its constituent parts, the spatial organization of its parts, or both with the distractors displayed with it. Sharing of parts and sharing of spatial organization both negatively affected visual search performance, and these effects were strictly additive. These findings support theories of complex visual object perception that assume a parsing of the stimulus into its higher-order constituents (volumetric parts or visible surfaces). The additivity of the effects demonstrates that information on parts and information on spatial organization are processed independently in visual search.
本文报告了一项使用合成三维物体的视觉搜索实验。目标物体与同时呈现的干扰物共享其组成部分、部分的空间组织或两者皆共享。部分共享和空间组织共享均对视觉搜索性能产生负面影响，且这些影响是严格相加的。这些发现支持了复杂视觉物体感知理论，该理论假设将刺激解析为其高阶成分（体积部分或可见表面）。效应的相加性表明，在视觉搜索中，关于部分的信息和关于空间组织的信息是独立处理的。
