This paper describes a test of Perceptual Control Theory (PCT), which views motor control as part of a process of controlling perceptual inputs rather than motor outputs. Sixteen undergraduate students (M age = 19.9 yr.) were asked to control one of three different perceptual aspects of an animated display--a shape, a motion or a sequence--using the same motor output, a key press. Animation rate was varied while quality of control was measured in terms of the proportion of time that the perception was maintained in the goal state. The results showed that increased animation rate made it hardest to control the more complex perceptions (motion and sequence) even though the same output was used to control all perceptions. This result is consistent with PCT, which predicts that the temporal constraints on control are ultimately a function of the type of perception controlled rather than the type of output used to control it.
本文描述了一项感知控制理论（PCT）的测试，该理论将运动控制视为控制感知输入过程的一部分，而不是控制运动输出。十六名大学生（平均年龄= 19.9 岁）被要求使用相同的运动输出（按键）来控制动画显示的三个不同感知方面之一——形状、运动或序列。动画速度变化，而控制质量则根据感知保持在目标状态的时间比例来衡量。结果表明，即使使用相同的输出来控制所有感知，增加动画速度也使得更复杂的感知（运动和序列）最难控制。这一结果与 PCT 一致，PCT 预测控制的时间约束最终是受控制的感知类型的函数，而不是用于控制它的输出类型。
