The aim of the present study was to investigate whether the representation of parts and the configuration and orientation of complex objects were separate or interdependent. Participants were asked to match parts and configuration of novel 3-D objects with constant or varied features in irrelevant dimensions. The results of both Exp. 1 (sequential matching) and Exp. 2 (simultaneous matching) showed that both sensitivity and response time (RT) of part matching were influenced by whether the irrelevant configuration remained constant or varied. Both sensitivity and RT for configuration matching were affected by the variation of irrelevant parts in Exp. 2, but only sensitivity was affected in Exp. 1. These results demonstrated an interdependent pattern of representations of parts and relations but different interactive patterns in memory and perception. The results of Exp. 3 showed orientation dependency in a configuration-matching task but orientation invariance in a part-matching task. Consistent with a study done in 2000 by Edelman and Intrator, these results suggest an interactive processing between configuration and orientation but an independent processing between the parts and orientation.
本研究旨在探讨物体部分的表示以及复杂物体的结构和方向是否是独立的还是相互依赖的。要求参与者将新的 3-D 物体的部分和结构与无关维度的恒定或变化特征相匹配。实验 1（顺序匹配）和实验 2（同时匹配）的结果均表明，部分匹配的敏感性和反应时间（RT）都受到无关结构是否保持不变或变化的影响。在实验 2 中，配置匹配的敏感性和 RT 都受到无关部分变化的影响，但在实验 1 中仅敏感性受到影响。这些结果表明，部分和关系的表示存在相互依存的模式，但在记忆和感知中存在不同的交互模式。实验 3 的结果表明，在配置匹配任务中存在方向依赖性，但在部分匹配任务中存在方向不变性。与 2000 年 Edelman 和 Intrator 的一项研究一致，这些结果表明，配置和方向之间存在交互式处理，但部分和方向之间存在独立处理。
