坐着的时候，病人拿了一个玻璃杯，把它交给检查员，然后拿起一个罐子。他把水倒进杯子里，放下水壶，拿起杯子。'. Lhermitte在额叶损伤患者中描述的这种强迫行为是一个例子，说明在没有任何内部动机的情况下，视觉刺激如何促使患者采取行动并“抓住呈现的物体并使用它们”。我们调查了这种行为是否是一个正常的，自动的对象动作转换的病理表现。为了验证这一点，我们让正常受试者在准备执行抓握动作时，通过视觉方式向他们展示与要执行的任务无关的图画。图画视觉上与要抓的物体一致，明显减少了抓的反应时间。这些数据代表了视觉启动存在的第一个证据。看到一个物体有助于与该物体的视觉属性一致的动作。
'WHILE seated, the patient took a glass, gave it to the examiner and then picked up a jug. He poured water into the glass and, having put down the jug, took the glass ...'. This compulsive behaviour, described by Lhermitte in patients with frontal lobe lesions, is an example of how, without any internal motivation, visual stimuli may impel a patient to act and 'grasp the objects presented and use them'. We investigated whether this behaviour is a pathological manifestation of a normal, automatic object to action transformation. To test this, we primed normal subjects, while ready to execute a grasping movement, by visually presenting them with drawings irrelevant to the task to be executed. Drawings visually congruent with the object to be grasped markedly reduced the reaction time for grasping. These data represent the first evidence for the existence of a visuomotor priming. Seeing an object facilitates an action congruent with the visual properties of that object.
