RESEARCH TO INVESTIGATE FACTORS AFFECTING MULTIPLE-TASK PSYCHOMOTOR PERFORMANCE

摘要

Fifteen male subjects participated in an experiment designed to study: (a) the 24-hour test-retest reliability and intercorrelation of a battery of seven performance tasks; (b) the effects of performing simultaneously various combinations of physically compatible tasks; (c) the 24-hour test-retest reliability and intercorrelation of a battery of four psychophysio¬logical variables; and (d) the relation of psychophysiological criterion measures to performance criteria and to conditions of task presentation.nThe results indicate moderately high reliability and sensitivity for five of the performance task criteria, but a negligible amount of intercor¬relation. While no significant correlation was obtained between performance scores and measures of psychophysiological activity, several of the psycho¬physiological measures showed significant reliability, intercorrelation, and sensitivity to conditions of rest and performance activity.
