ABSTRACT
Information regarding properties of workload assessment techniques as applied to multi-task environments is reviewed in this chapter. Workload assessment in multi-task environments can, therefore, involve factors and impose unique requirements that may not be present in traditional laboratory studies that have been employed in the development of many workload assessment techniques. The chapter reviews current data related to applications of workload assessment techniques in a variety of single- and multi-task environments and provides recommendations for future work concerning refinement of applications guidelines for such techniques. It also explains classes of workload assessment techniques. An important implication of very high loading levels is that the operator may be too busy or not have sufficient reserve processing capacity to generate the responses required for certain assessment techniques. Important factors that can affect workload are associated with the changes in information processing that can occur with operator training.
