Effects of altering task components on perceptual-motor task learning

Abstract

In training operators of man-machine systems, how will altering the task influence learning progress at various stages in this sequence? After trying it out in a pilot study, the main experiment involved 108 male soldiers. "The apparatus consisted of an electronic compensatory tracking device which required S to maintain a target indicator in the center of a 5-in. oscilloscope… . Time on target was the primary measure of performance." A temporary decrement in performance was produced from altering task components later in learning. Greater effect followed from changes taking place earlier. 16 refs. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
