When the interval between a non-predictive cue and a target appearing at the same spatial location is longer than about 200 ms, target performance is typically poorer than when the cue and target appear at different locations. Recent studies have shown that this effect, known as inhibition of return (IOR), can occur at multiple cued locations, and is enhanced when multiple cues are presented at the same spatial location. However, little is known about how the magnitude of IOR at one spatial location is influenced by a subsequent or preceding cue presented at a different spatial location. We investigated this issue by presenting single or multiple cues at varying inter-cue intervals prior to target onset. Results suggest that the magnitude of IOR at a given location is influenced by the presentation of a preceding cue, but that once IOR occurs, it is unaffected by the presentation of a subsequent cue.
当非预测线索和出现在同一空间位置的目标之间的时间间隔长于约 200 毫秒时，目标的表现通常不如线索和目标出现在不同位置时好。最近的研究表明，这种被称为返回抑制（IOR）的效应可以在多个提示位置发生，并且当多个提示出现在同一空间位置时，IOR 会增强。然而，对于一个空间位置的 IOR 幅度如何受到随后或先前在不同空间位置呈现的提示的影响，知之甚少。我们通过在目标出现之前在不同的时间间隔呈现单个或多个提示来研究这个问题。结果表明，在给定位置的 IOR 幅度受到先前提示的呈现的影响，但一旦发生 IOR，它不受随后提示的呈现的影响。
