返回抑制(IOR)指的是对将注意力返回到最近参加过的地点的偏见。在本实验中，我们通过引入涉及工作记忆成分的次级任务(在线索和目标之间的时间间隔内)来考察工作记忆在返回抑制中的作用。当次要任务本质上是非空间性的(监控奇数位或加法位数)时，存在IOR，尽管存在次要任务的总体反应时更长。当任务涉及空间工作记忆负荷(记住箭头的方向或物体的方向)时，返回抑制被消除。然而，当参与者有动机处理箭头的方向性但不需要使用任何记忆系统时，IOR在外围位置持续存在。总体而言，研究结果表明，返回抑制部分受空间工作记忆系统的调节。
Inhibition of return (IOR) refers to a bias against returning attention to a location that has been recently attended. In the present experiments, we examined the role of working memory in IOR by introducing secondary tasks (in the temporal interval between the cue and the target) that involved a working memory component. When the secondary task was nonspatial in nature (monitoring odd digits or adding digits), IOR was present, although overall reaction times were greater in the presence of the secondary task. When the task involved a spatial working memory load (remembering the directionality of arrows or the orientation of objects), IOR was eliminated. However, when the participants had incentive to process the directionality of an arrow but did not have to use any memory system, IOR persisted at peripheral locations. Overall, the results suggest that IOR is partially mediated by a spatial working memory system.
