Simple reaction times to lateralized visual (Experiment 1) or auditory (Experiment 2) targets were studied in normal subjects. The targets were preceded by a visual or auditory cue located on the same (valid cue), or opposite (invalid cue) side as the subsequent target, or on both sides (neutral cue), with one of four cue target intervals. The validity of visual and auditory cues influenced the speed of response to the visual target but not to the auditory target. It is hypothesized that cross-modal cueing of spatial position works only with modalities for which a movement (e.g. saccade) leads to improved sensory analysis.
在正常受试者中研究了对侧化视觉（实验1）或听觉（实验2）目标的简单反应时间。在目标之前会出现一个视觉或听觉提示，该提示位于与后续目标相同（有效提示）、相反（无效提示）或两侧（中性提示）的位置，提示与目标之间有四种时间间隔。视觉和听觉提示的有效性影响了对视觉目标的反应速度，但不影响对听觉目标的反应速度。据推测，空间位置的跨模态提示仅适用于那些运动（如扫视）能改善感觉分析的模态。
