返回抑制（IOR）通常被解释为注意的定向，强调一种潜在的机制，抑制注意返回到先前选择的位置。最近的数据挑战了这一解释的程度，即IOR效应是在注意力指向的位置观察到的，而不需要注意力的重新定向。迄今为止，这些研究涉及内源性注意选择的注意，从而表明空间注意的自愿注意和返回抑制效应之间的分离。目前的工作证明了空间注意的无意识定向和返回抑制效应之间的分离。我们结合了非预测性的周边线索与非预测性的中央定向线索（箭头或凝视）。IOR效应被观察到独立于无意识空间定向。这些数据反对返回抑制的重新定向假说。我们提出了另一种解释，即IOR效应反映了在另一个事件（线索）之前编码的位置检测新事件（目标）的成本。
Inhibition of Return (IOR) is usually explained in terms of orientingreorienting 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.
