Preview search with moving stimuli was investigated. The stimuli moved in multiple directions, and preview items could change either their color or their shape before onset of the new (search) displays. In Experiments 1 and 2, the authors found that (a) a preview benefit occurred even when more than 5 moving items had to be ignored, and (b) color change, but not shape change, disrupted preview search in moving stimuli. In contrast, shape change, but not color change, disrupted preview search in static stimuli (Experiments 3 and 4). Results suggest that preview search with moving displays is influenced by inhibition of a color map, whereas preview search with static displays is influenced by inhibition of locations of old distractors.
研究了移动刺激下的预览搜索。刺激在多个方向上移动，并且预览项目可以在新的（搜索）显示开始之前改变其颜色或形状。在实验1和实验2中，作者发现：（a）即使必须忽略超过5个移动项目，预览优势仍然存在；（b）颜色变化而非形状变化会干扰移动刺激下的预览搜索。相比之下，形状变化而非颜色变化会干扰静态刺激下的预览搜索（实验3和实验4）。结果表明，移动显示下的预览搜索受颜色图抑制的影响，而静态显示下的预览搜索受旧干扰物位置抑制的影响。
