心理物理学研究表明,人类对图像加速度的敏感度低于对图像速度的敏感度(例如,Gottsdanker,1956; Werkhoven,Snippe和Toet,1992)。因为有证据表明,一个共同的运动处理阶段有利于感知和追求(例如,Watamaniuk和Heinen,1999),无论是追求应该同样受损,在歧视加速度或它必须接收输入从一个不同的系统,处理视觉运动的感知。我们评估了追求的敏感性加速度或速度,并与那些在知觉实验中获得的结果进行了比较,用类似的刺激和任务。具体来说,观察者对以随机选择的基本速度和随后的加速度移动的目标进行心理物理判断。通过分析整个刺激集(按目标加速度或速度排序)的性能,比较了视觉和心理物理辨别力。目标加速度的追踪和感知能力高于速度,进一步证明了共同的运动处理阶段限制了两个系统的性能。
Psychophysical studies have demonstrated that humans are less sensitive to image acceleration than to image speed (eg, Gottsdanker, 1956; Werkhoven, Snippe, & Toet, 1992). Because there is evidence that a common motion-processing stage subserves perception and pursuit (eg, Watamaniuk & Heinen, 1999), either pursuit should be similarly impaired in discriminating acceleration or it must receive input from a system different from the one that processes visual motion for perception. We assessed the sensitivity of pursuit to acceleration or speed, and compared the results with those obtained in perceptual experiments done with similar stimuli and tasks. Specifically, observers pursued or made psychophysical judgments of targets that moved at randomly selected base speeds and subsequent accelerations. Oculomotor and psychophysical discrimination were compared by analyzing performance for the entire stimulus set sorted by either target acceleration or speed. Thresholds for pursuit and perception were higher for target acceleration than speed, further evidence that a common motion-processing stage limits the performance of both systems.
