返回抑制（IOR）是指当前一个刺激在空间中占据相同位置时，对目标的反应时间减慢。最近，我们观察到一个强大的抑制效应的颜色和形状在适度复杂的显示：这是更难检测到一个目标与特定的非空间属性，如果具有相同属性的刺激最近的注意力的焦点。这种非空间抑制效应在简单的显示器中通常没有发现。在本研究中，我们测试如何基于位置和非空间的抑制效应作为显示复杂性（8，6，4和2个位置）的函数而变化。结果表明：（1）基于位置的抑制效应在更复杂的显示中更强，而非空间抑制在更复杂的显示中仅略强;（2）非空间抑制效应在更长的SOA中出现，而不是基于位置的效应;（3）非空间抑制仅在线索和目标出现在相同位置时出现，证实了纯粹的特征重复不会产生成本。总而言之，结果与基于按空间位置组织的对象文件的感知过程一致。使用比最常用的更复杂的显示器提供了一种更敏感的方法来观察抑制过程在促进视觉搜索中的作用。此外，为了清楚地看到抑制效应是如何起作用的，需要使用一组相对广泛的线索-目标时间关系。
Inhibition of return (IOR) refers to the slowing of reaction times to a target when a preceding stimulus has occupied the same location in space. Recently, we observed a robust inhibitory effect for color and shape in moderately complex displays: It is more difficult to detect a target with a particular nonspatial attribute if a stimulus with the same attribute was recently the focus of attention. Such nonspatial inhibitory effects have not generally been found in simpler displays. In the present study, we test how location-based and nonspatial inhibitory effects vary as a function of display complexity (8, 6, 4 and 2 locations). The results demonstrated that: (1) location based inhibition effects were much stronger in more complex displays, whereas the nonspatial inhibition was only slightly stronger in more complex displays; (2) Nonspatial inhibitory effects emerged at longer SOAs than location-based effects; and (3) Nonspatial inhibition only appeared when cues and targets occurred in the same locations, confirming that pure feature repetition does not produce a cost. Taken together, the results are consistent with perceptual processes based on object files that are organized by spatial location. Using somewhat more complex displays than are most commonly employed provides a more sensitive method to observe the role of inhibitory processes in facilitating visual search. In addition, using a relatively wide set of cue-target timing relationships is necessary in order to clearly see how inhibitory effects operate.
