尽管人们普遍认为，抑制返回(IOR)通过阻止重新检查先前检查的地点来帮助搜索，但其影响实际上似乎随着目标地点的增加而下降。我们检验了这一矛盾结果的三个可能原因：(1)IOR是容量有限的；(2)IOR对目标位置概率的细微变化很敏感；(3)IOR随距离先前关注的位置的距离而衰减。目前的研究为第三种解释提供了有力的支持，表明抑制的梯度集中在先前注意的位置。我们注意到，这种抑制梯度解决了文献中的一个悖论。此外，我们推测，抑制梯度可能反映了一个“相似空间”，在这个空间中，接近线索的目标位置由于它们与被线索位置的相似性而被标记为抑制。目标位置距离越远，它与提示位置的相似性就越小，因此它受到的抑制就越少。
Although inhibition of return (IOR) is widely believed to aid search by discouraging reexamination of previously inspected locations, its impact actually appears to decline as the number of target locations increases. We test three possible reasons for this paradoxical result: (1) IOR is capacity-limited, (2) IOR is sensitive to subtle changes in target location probability, and (3) IOR decays with distance from a previously attended location. The present investigation provides strong support for the third explanation, indicating that a gradient of inhibition is centered on previously attended locations. We note that this inhibitory gradient resolves a paradox in the literature. Moreover, we speculate that the inhibitory gradient may reflect a "similarity space" within which target locations near to the cue are tagged with inhibition due to their similarity to the cued location. The farther the target location is away, the less similar it is to the cued location, and thus the less inhibition it receives.
