Abstract
Western society continues to become increasingly technological and, by extension, automated. It should come as no surprise, then, that researchers have devoted a considerable amount of time and effort to identifying and understanding psychological constructs, such as cognitive workload and trust, as they apply to the relationship between human and machine, especially in the military domain. The current research seeks to expand on past work by considering the joint influence of workload and system reliability on operator trust, as well as performance, as measured by accuracy in identifying a target stimulus, reaction time, and situation awareness. Results suggested that task workload had a significant impact on all measured aspects of operator performance, but not trust in the automated system. Surprisingly, system reliability had no statistical effect on operator performance or measured trust.
