Abstract : Twenty-four subjects performed two tasks, a cognitive task and a motor task, both with three levels of task difficulty. Twelve subjects provided workload ratings via the Subjective Workload Assessment Technique (SWAT) and twelve used the modified Cooper-Harper scale (MCH). The objective of this study was to empirically determine if there were differences in the sensitivities of the two subjective workload measures as task difficulty was manipulated. There was no difference between the two techniques sensitivity. Both rating scales varied significantly as a function of task difficulty manipulations, supporting the sensitivity of both techniques to the workload conditions used.
