“…Empirically, the weighted averages have not been found to be superior to the simple average of the sub-scales (Christ et al, 1993;Hendy, Hamilton, & Landry, 1993). Additionally, there is some concern that the six subscales are often perceived as measuring only one or two constructs and interpretation of the individual subscales should only be made with caution (Bailey & Thompson, 2001).…”

SUPPLEMENTARY NOTES ABSTRACTThe introduction of automation into highly complex systems has occurred under several guiding principles. The appUcation of these principles has often resulted in tenuous interactions with regard to human performance within complex systems. With advances in technology increasing, it is no longer applicable to look at single automated tools but rather at how several automated tools fit together and affect system performance. A common framework utilizing a model of human interaction with automation based on simple human information-processing stages was used in the design and analysis of 4 experiments. The first 3 experiments utilized a visual search paradigm and varied the stage the automation was present and the reliability of the automation that was used. For these studies, the automation that helped the operator locate the potential target demonstrated a clear advantage over automation that recommended a course of action when the automation was perfectly reliable. The 4* study examined all of the possible combinations of manual & automated aiding for the 4 stages in an air-to-ground search and destroy mission that was carried out in a high fidelity combat flight simulator. By utilizing separate stage metrics, it was demonstrated that the automation in 1 stage influenced performance in subsequent stages and throughout the entire mission. SUBJECT TERMS TmS PAGE INTENTIONALLY LEFT BLANK ABSTRACTThe introduction of automation into highly complex systems has occurred under several guiding principles. The application of these principles has often resulted in tenuous interactions with regard to human performance within complex systems. With advances in technology increasing at an exponential rate it is no longer applicable to look at single automated tools but rather at how several automated tools fit together and affect system performance. Automation can change the nature of the demands on the operator and produce subsequent changes in performance not seen when automation is absent. Problems in human-automation interaction have included unbalanced workload, reduced system awareness, decision bias, mistrust, over;reliance, complacency, and reduced manual skills. Further, these problems can be exacerbated when the automation is less than perfectly reliable.A common framework utilizing a model...
