Abstract
This study was an evaluation of sedentary task performance under temperature/time combinations specified in the proposed NIOSH criteria document for exposure to hot environments. Performance was investigated for an array of simple perceptual motor tasks, using repeated measures under several thermal conditions. The four perceptual motor tasks were: reaction time, pursuit tracking, eye/hand coordination and mental multiplication. The experimental protocol called for each subject to perform one task for a 2 1/2 minute interval, at which time he would move to the next task in sequence with a 1 minute rest break. A total of 31 male subjects participated in the study. Performance on specific tasks varied widely under different temperature combinations. There was no overwhelming decrement in performance, enhancement of performance, or lack of effect on performance which transcended all of these tasks under different time and temperature conditions. Pursuit tracking performance at lower temperatures was consistently and significantly better than performance when the temperature was elevated. The reaction time task and the speed of multiplication task showed similar performance responses in hot environments under the most severe thermal stress of wet bulb globe temperature level 4 (110 degrees-F). For the hand/eye coordination and pursuit motor tasks there was an indication of a reversal of thermal effects which resulted in poorer performance at wet bulb globe temperature level 2 (90 degrees-F) than that at somewhat higher or lower temperature levels.
