Level of Automation Effects on Situation Awareness and Functional Specificity in Automation Reliance

This thesis investigates the relationships between performance, workload, and situation awareness at varying levels of automation. The relationships observed in this study are compared to a description put forth to formalize the conventional interpretation of the trade-off between the benefits of automation during routine operation and the costs under conditions of automation failure. The original work stipulated that this “routine-failure trade-off” is likely a simplification affected by contextual factors. This work therefore aimed to i) provide empirical evidence to support or refute the trade-off and ii) to identify possible extenuating factors. The results generally supported the routine-failure trade-off, and considered in light of the functional structure of the task suggested that the relationships between goals and individual functions specific to a given task seem to affect the overall costs and benefits of automation through the mechanism of selective reliance. Further work is required to validate the findings of this study.
