神经心理学的结果支持的建议，人类视觉系统是组织成不同的处理途径，一个有意识的感知和一个控制的行动。在这里，我们比较感知和动作反应后的预响应延迟。实验一要求参与者重现记忆中的位置，发现虽然知觉匹配不受延迟长达4秒，指向反应显着偏见后，只有2秒。实验2研究了是否运输和，锉刀组件的一个自然的delaysile运动同样受到影响。手腕的峰值速度和峰值抓地力孔径的影响等效延迟，这表明，两个组件的一个delicile运动有类似的时间限制。这两个实验的结果都与最初由米尔纳和古德尔提出的一般的视神经离子-作用二分法一致[The visual brain in action，Oxford：Oxford University Press，1995]。(C)2002爱思唯尔科技有限公司。保留所有权利。
Neuropsychological results support the proposal that the human Visual system is organised into distinct processing pathways, one for conscious perception and one for the control of action. Here, we compare perceptual and action responses following a pre-response-delay. Experiment I required participants to reproduce remembered locations and found that although perceptual matches were unaffected by delays of up to 4 s, pointing responses were significantly biased after only 2 s. Experiment 2 examined whether both the transport and,rasp components of a natural prehensile movement were similarly affected by delay. Both peak wrist velocities and peak grip-apertures were affected equivalently by delay, suggesting that the two components of a prehensile movement have similar temporal constraints. The results from both experiments are consistent with the general percept ion-action dichotomy as originally proposed by Milner and Goodale [The visual brain in action, Oxford: Oxford University Press, 1995].
