Abstract
Two independent groups of 24 female college students acted as subjects in an experiment using a single, compensatory pursuit task. One group used a knob control; the other, a lever. In both studies, the zero position of the pointer and the motion relation between pointer and control were varied. Time-on-target performance scores were measured with the pointer ain a 12 or a 6 o'clock zero position and with the direction of movement of the pointer and control either agreeing or disagreeing. The pointer dial and the control were aligned vertically in the same plane; the arc of pointer movement was considerably less than 45 degrees on either side of the zero position. The major conclusions drawn were that 1) performance is affected by an interaction between the pointer position and the pointer-control motion relation, 2) subjects behave as if they perceive the rotary mechanical movements of bothe linearly and curcilinearl, 3) the "motion agreement principle" operates in both perceptual sets and performance is a result of the effects of bothe sets combined.
