返回抑制（IOR）是指当线索和目标之间存在较长的时间间隔时，出现在先前线索位置的目标比出现在先前未线索位置的目标反应更慢。本实验的目的是确定返回抑制的大小是否受到先前试验的类型（线索或未线索）和/或先前试验中线索/目标的位置的影响。尽管没有观察到线索/目标位置的影响，但以前的试验类型有明显的影响，因为无线索试验相对于有线索试验的IOR更大。这种效应归因于反应时间的差异，作为先前试验类型的函数：具体而言，当先前试验类型相同时，参与者对提示和未提示试验的反应更快。
Inhibition of return (IOR) refers to the finding that targets appearing at previously cued locations are more slowly responded to than targets appearing at previously uncued locations when a relatively long temporal interval occurs between the cue and target. This experiment was conducted to determine whether the magnitude of IOR is influenced by the type of preceding trial (cued or uncued) and/or the location of the cue/target on the previous trial. Although no effect of cue/target location is observed, there was a marked effect of previous trial type, as IOR was greater following an uncued trial relative to a cued trial. This effect was attributable to differences in the response time as a function of previous trial type: specifically, participants were faster to respond to cued and uncued trials when the previous trial type was identical.
