Inhibition of return (IOR) prevents the immediate reorientation to previously attended locations, such that unattended locations are prioritized. In the current study, we were interested in whether saccadic IOR is affected by the storage of visuospatial information in working memory (WM) during a visual search task. To this end, participants searched a display for a target letter once while holding no, two, or four object locations in their spatial WM. During the search, either a previously inspected or an uninspected item was probed, and the participants were instructed to immediately saccade to this probed item before resuming the search. The results showed that saccadic latencies to previously inspected items were longer than to uninspected items, indicating the presence of IOR during the search. However, this effect was observed regardless of the number of item locations held in the spatial WM. This finding suggests that saccadic IOR does not rely on visuospatial WM in visual search.
返回抑制（IOR）会阻止立即重新定向到先前关注过的位置，从而使未被关注的位置具有优先级。在当前研究中，我们感兴趣的是，在视觉搜索任务期间，眼跳IOR是否会受到工作记忆（WM）中视觉空间信息存储的影响。为此，参与者在空间WM中不持有、持有两个或四个物体位置的情况下，对一个显示画面搜索一次目标字母。在搜索过程中，对一个先前检查过或未检查过的项目进行探测，并指示参与者在恢复搜索之前立即向该被探测项目进行眼跳。结果表明，对先前检查过的项目的眼跳潜伏期比对未检查过的项目更长，这表明在搜索过程中存在IOR。然而，无论空间WM中持有的项目位置数量如何，都观察到了这种效应。这一发现表明，在视觉搜索中，眼跳IOR不依赖于视觉空间WM。
