ABSTRACT

Previewing distractors facilitates efficient detection of a target appearing subsequently with any remaining distractors. Visual marking, specifically, top-down inhibition of old items, is induced by the inhibitory template that forms while previewing old items, and continues to be maintained during the target search. Extant studies have examined inhibitory template characteristics using additional tasks or events. In the present study, an endogenous cueing paradigm was combined to examine the interaction between spatial facilitation of cueing and the ability to inhibit old items. An endogenous cue was presented during the preview period, resulting in competition between two top-down controls, endogenous orienting and the inhibitory template; endogenous spatial cueing and visual marking effects did not simply function concurrently. Rather, either of them could be effective alternately for one trial. These findings suggest that the inhibitory template cannot function concurrently with another top-down control for visual search, though it is not damaged.

摘要

预览干扰物有助于有效地检测随后出现的任何剩余干扰物的目标。视觉标记，特别是对旧项目的自上而下的抑制，是由在预览旧项目时形成的抑制模板引起的，并且在目标搜索过程中会一直保持下去。现有研究已经使用其他任务或事件检查了抑制模板的特征。在本研究中，内生的提示范式被结合起来，以检查提示的空间促进与抑制旧物品的能力之间的相互作用。在预览期间出现了内源性提示，导致两个自上而下的控件（内源性定向和抑制模板）之间的竞争。内源性空间提示和视觉标记效果并不能简单地同时发挥作用。而是 它们中的任何一个对于一次试验都可以交替有效。这些发现表明抑制模板不能与另一个用于视觉搜索的自上而下的控件同时运行，尽管它没有损坏。
