Abstract
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.
