我们报告了一项实验，旨在检查跨模式注意力捕获是否会影响参与者在无速同时性判断（SJ）任务中的表现。十六名参与者对两个视觉目标（一个出现在注视点的两侧）是同时出现还是相继出现做出了完全不快速的判断。在第一个视觉目标出现前 200 毫秒，在一侧呈现空间非预测性听觉提示。结果表明，无提示视觉目标必须在提示视觉目标之前 17 毫秒出现，才能同时感知到两种刺激。这一结果与这样的观点是一致的，即在呈现空间非预测性外围听觉提示之后自动跨模式捕获注意力会加速在有提示（相对于无提示）位置呈现的视觉刺激的感觉处理。
We report an experiment designed to examine whether or not crossmodal attentional capture affects the performance of participants in an unspeeded simultaneity judgement (SJ) task. Sixteen participants made completely unspeeded judgements as to whether two visual targets (one presented on either side of fixation) had been presented simultaneously or else successively. A spatially nonpredictive auditory cue was presented on one side 200 ms before the onset of the first visual target. The results showed that the uncued visual target had to be presented 17 ms before the cued visual target in order for the two stimuli to be perceived as simultaneous. This result is consistent with the view that the automatic crossmodal capture of attention that follows the presentation of a spatially nonpredictive peripheral auditory cue leads to the speeding-up of the sensory processing of visual stimuli presented at the cued (relative to the uncued) location.
