An Experimental Investigation of Skill,Rule,and Knowledge-Based Performance under Noise Conditions

Abstract

An important aspect of soldier effectiveness is the ability to perform multiple tasks in the face of stress. It has likewise been found that performance on a secondary task degrades when multiple tasks are being performed simultaneously and that the presence of stress is associated with general decrements in performance. Consequently, it is important to understand how the presence of stress impacts complex task performance in the military domain. The purpose of the present study was to investigate the effect of noise on multiple task performance, subjective workload, and subjective dimensions of stress framed within the skill — rule — and knowledge based trichotomization.
