Processing Phenomena and the Dissociation between Subjective and Objective Workload Measures.

Abstract

Causes of dissociation between subjective workload assessments and objective performance were investigated. A Sternberg memory search task was utilized. Sternberg task configurations varied in the automaticity of performance, stimulus presentation rate, discernability of stimuli, and the value of good performance. Automaticity in Sternberg task performance was manipulated by using two independent sets of stimuli; one of which was consistently mapped (i.e., targets were always the same) while the other was inconsistently mapped (i.e., targets changed over trials). Also, all Strenberg configurations were performed both as single tasks and as part of dual task combinations (with a manual control task). During testing subjects rated all trials on eight typical bipolar rating scales. The results were interpreted as supporting cognitive-processing-based experimentation in subjective workload assessment aimed at identifying differences between the cognitive processing accounting for subjective assessments and those processes that produce performance.
