研究了处理视觉反馈信息以控制目标动作所需的时间。实验一（11名大学生）表明，从瞄准反应的初始部分撤回视觉反馈信息对运动结果的影响不大。这一发现表明视觉处理时间可能比以前的估计更快。实验I中采用的视觉操作范例与实验II（3秒）中的高速电影摄影技术相结合，以获得视觉处理时间的直接估计。运动模式的检查表明，视觉错误信息的呈现和开始运动校正之间的平均时间为135毫秒。研究结果支持的论点，即处理视觉错误信息，并使用此信息的运动控制所需的时间比以前估计的190-300毫秒短。(23参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Investigated the time needed to process visual feedback information for the control of aimed movements. Exp I (11 undergraduates) demonstrated that withdrawing visual feedback information from the initial portions of aiming responses has little effect on movement outcome. This finding suggested that visual processing times may be faster than previous estimates. The vision manipulation paradigm employed in Exp I was combined with high-speed cinematography techniques in Exp II (3 Ss) to obtain a direct estimate of visual processing time. Examination of movement patterns indicated that the average time between the presentation of visual error information and the initiation of a movement correction was 135 msec. Findings support the contention that the time needed to process visual error information and to use this information for movement control is shorter than previous estimates of 190–300 msec.(23 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
