参与者在中央视野中观察物体，然后在左侧或右侧视野中短暂地呈现这些物体的相同或不同的深度方向视图。不同取向的观点包含相同或不同的一组部分和关系。视点依赖性启动时，观察到测试视图直接向右半球（RH），但不是当测试视图直接向左半球（LH）。此外，这种结果模式并不取决于是否可以从不同取向的观点中恢复相同或不同的一组部分和关系。结果支持这样的理论：RH中的特定子系统比抽象子系统更有效地运行，并且以产生视点相关效果的方式存储对象，而抽象子系统比LH中的特定子系统更有效地运行，并且不存储对象以视点相关的方式。
Participants viewed objects in the central visual field and then named either same or different depth-orientation views of these objects presented briefly in the left or the right visual field. The different-orientation views contained either the same or a different set of parts and relations. Viewpoint-dependent priming was observed when test views were presented directly to the right hemisphere (RH), but not when test views were presented directly to the left hemisphere (LH). Moreover, this pattern of results did not depend on whether the same or a different set of parts and relations could be recovered from the different-orientation views. Results support the theory that a specific subsystem operates more effectively than an abstract subsystem in the RH and stores objects in a manner that produces viewpoint-dependent effects, whereas an abstract subsystem operates more effectively than a specific subsystem in the LH and does not store objects in a viewpoint-dependent manner.
