Description: This thesis presents two experiments of human monitoring of an automated system in a multi-task environment, considering both sampling behaviour and subjective reports of trust and self-confidence.The second experiment investigates the effect of providing participants with information about the context-related nature of automation reliability on participants' monitoring behaviour. Results are compared against those of the first experiment where no information about automation reliability was provided. They suggest that providing context can mitigate the detrimental effect of constant and highly reliable automation on participants' behaviour. Implications for future research on human-automation interaction are described.The first experiment addresses the issue of complacency. It replicates Parasuraman et al. (1993) wherein participants were said to be lulled into complacency by unchanging automation. Results of this first experiment provide empirical support for Moray's (2003) assertion that attention allocation and psychological factors should be considered when evaluating monitoring performance and concluding about complacency.
