Current Issues in Subjective Assessment of Workload

Abstract

Because of their practical utility, subjective measures have been widely used as workload assessment techniques. There has also been increased support in the recent literature for the importance of including subjective measures as part of a comprehensive workload assessment methodology. In spite of the widespread use and importance of subjective techniques, several significant issues which pertain to their development and use remain unresolved. One such issue is related to the development of a generalized subjective workload assessment procedure, while a second issue concerns the need to identify factors or variables that contribute to the subjective experience of workload. This paper discusses both issues and outlines some recent research which is applicable to each area.
