It is currently controversial whether auditory events produce inhibition of return (IOR). Although some authors argue that this can arise, others propose that peripheral auditory cues do not produce the characteristic IOR pattern of delayed detection latencies for ipsilaterally presented auditory or visual targets, unless a saccade is made to the cued location. We suggest that these previous discrepancies may depend on whether attention is reoriented centrally following the peripheral sound. We presented spatially uninformative peripheral auditory cues prior to visual targets requiring speeded detection responses. IOR was found in the absence of eye movements, provided an auditory reorienting event was presented at central fixation between onset of the peripheral cue and the subsequent target, but not when the central reorienting event was visual. A subsequent experiment demonstrated that auditory IOR between successive targets is similarly significantly reduced in the absence of an appropriate central reorienting event. These results imply that auditory stimuli can induce IOR directly. Previous failures to demonstrate IOR following auditory cues may have been due to an opposing influence of long-lasting attentional facilitation at the cued location, rather than to the putative inability of auditory stimuli to engage oculomotor processes generating IOR.
目前，听觉事件是否会产生返回抑制（IOR）存在争议。尽管一些作者认为这是可能出现的，但另一些人则提出，除非向提示位置进行扫视，否则外周听觉线索不会产生同侧呈现的听觉或视觉目标延迟检测潜伏期的典型IOR模式。我们认为，这些先前的差异可能取决于外周声音之后注意力是否在中枢重新定向。我们在需要快速检测反应的视觉目标之前呈现空间上无信息的外周听觉线索。在没有眼动的情况下发现了IOR，前提是在外周线索开始和随后的目标之间，在中央注视点呈现一个听觉重新定向事件，但当中央重新定向事件是视觉事件时则没有。随后的一项实验表明，在没有适当的中央重新定向事件的情况下，连续目标之间的听觉IOR同样显著降低。这些结果意味着听觉刺激可以直接诱发IOR。先前未能证明听觉线索后出现IOR，可能是由于在提示位置长期存在的注意力促进作用的相反影响，而不是由于听觉刺激假定无法参与产生IOR的眼动过程。
