视觉位置提示提供的准备可以加速行为。然而，同时眼跳的视觉线索的作用仍然不清楚。在这项研究中，参与者通过用四个手指（每只手两个）中的一个按下四个反应键中的一个来执行空间预提示任务，同时监测眼球运动。在刺激之前，我们提出了一个中性线索（基线），手线索（对应于左与右的位置），或手指线索（对应于内部与外部的位置）。参与者要么保持固定在中心固定点上，要么自由移动眼睛。结果表明，在线索间隔眼跳改变了线索效应的模式。手指暗示试验中，眼跳空间不兼容（与兼容），随后需要的手动反应表现出较慢的手动RT。我们建议，眼跳和手动反应之间的干扰影响手动电机准备。
Preparation provided by visual location cues is known to speed up behavior. However, the role of concurrent saccades in response to visual cues remains unclear. In this study, participants performed a spatial precueing task by pressing one of four response keys with one of four fingers (two of each hand) while eye movements were monitored. Prior to the stimulus, we presented a neutral cue (baseline), a hand cue (corresponding to left vs. right positions), or a finger cue (corresponding to inner vs. outer positions). Participants either remained fixated on a central fixation point or moved their eyes freely. The results demonstrated that saccades during the cueing interval altered the pattern of cueing effects. Finger cueing trials in which saccades were spatially incompatible (vs. compatible) with the subsequently required manual response exhibited slower manual RTs. We propose that interference between saccades and manual responses affects manual motor preparation.
