Recent work shows that abrupt onsets reflexively capture attention and trigger saccades that compete with voluntary saccades. To test whether oculomotor capture occurs when no saccade is being planned, we measured fixational eye movements in the absence or presence of an abrupt onset at peripheral locations. We found no effect of abrupt onset location on the average pattern of eye movements during fixation. We conclude that the capture of eye movements by an abrupt onset only happens when the oculomotor system has been preset to make a saccade. This implies that the oculomotor system is not obligatorily driven by events in the visual array.
近期研究表明，突然出现的刺激会自动吸引注意力并引发与自主扫视相竞争的扫视运动。为了测试在没有计划进行扫视运动时是否会发生眼动捕捉，我们测量了在周边位置有无突然出现的刺激时的注视眼动。我们发现突然出现的刺激位置对注视期间眼动的平均模式没有影响。我们得出结论，突然出现的刺激引发的眼动捕捉仅在动眼系统已预设好进行扫视运动时才会发生。这意味着动眼系统并非必然由视觉阵列中的事件驱动。
