为了阐明固视线索在回归抑制（IOR）中的作用，本研究比较了四种情况：紧接在外周线索之后的固视线索、在刺激开始异步（SOA）的中间、紧接在目标开始之前或没有固视线索。对于 200 毫秒的 SOA，当注视提示不存在或在外围提示之后立即出现时，会发现 IOR 较小。对于 400 毫秒和 800 毫秒 SOA，四种条件之间没有发现差异。这些发现表明，在一段短暂的时间内，注意力无法从外围提示的位置上转移。一旦注意力从外围提示位置撤回，就可以在短 SOA 处找到 IOR。
To clarify the role of the fixation cue in inhibition of return (IOR), the present study compared four conditions: fixation cue immediately after the peripheral cue, in the middle of the stimulus-onset asynchrony (SOA), immediately before the onset of the target, or no fixation cue. With a 200-ms SOA, less IOR was found when the fixation cue was either absent or occurred immediately after the peripheral cue. No differences between the four conditions were found with 400-ms and 800-ms SOAs. These findings suggest that there is a brief period of time in which attention cannot be withdrawn from the peripherally cued location. Once attention has been withdrawn from the peripherally cued location, IOR can be found at short SOAs.
