Inhibition of Return (IOR) is usually explained in terms of orienting-reorienting of attention, emphasizing an underlying mechanism that inhibits the return of attention to previously selected locations. Recent data challenge this explanation to the extent that the IOR effect is observed at the location where attention is oriented to, where no reorienting of attention is needed. To date, these studies have involved endogenous attentional selection of attention and thus indicate a dissociation between the voluntary attention of spatial attention and the IOR effect. The present work demonstrates a dissociation between the involuntary orienting of spatial attention and the IOR effect. We combined nonpredictive peripheral cues with nonpredictive central orienting cues (either arrows or gaze). The IOR effect was observed to operate independent of involuntary spatial orienting. These data speak against the "reorienting hypothesis" of IOR. We suggest an alternative explanation whereby the IOR effect reflects a cost in detecting a new event (the target) at the location where another event (a cue) was coded before.
返回抑制（IOR）通常根据注意力的定向 - 重新定向来解释，强调一种潜在机制，该机制会抑制注意力返回到先前选择的位置。最近的数据对这一解释提出了挑战，因为在注意力定向的位置观察到了IOR效应，而在此处并不需要注意力的重新定向。迄今为止，这些研究涉及注意力的内源性选择，因此表明空间注意力的自愿注意与IOR效应之间存在分离。目前的研究表明空间注意力的非自愿定向与IOR效应之间存在分离。我们将非预测性外周线索与非预测性中央定向线索（箭头或注视）相结合。观察到IOR效应的运作与非自愿空间定向无关。这些数据与IOR的“重新定向假说”相悖。我们提出了另一种解释，即IOR效应反映了在之前对另一个事件（一个线索）进行编码的位置检测新事件（目标）时的一种代价。
