Abstract
The current study was designed to empirically examine the effects of trust and automation reliability on multi-tasking performance in a simulated cockpit setting using the Multi-Attribute Task Battery II (MATB-II). The MATB-II simulates tasks often performed by pilots in-flight, tasking the operator with attending to automated systems and correcting errors when they inevitably occur. Over the course of three 30-minute trials, two levels of automation reliability were presented in the current study (R50% and R90%). It was hypothesized that automation reliability and trust would affect both workload and performance in this multi-tasking environment. Results indicated that reliability significantly affected monitoring performance on the MATB-II. More reliable automation resulted in poorer monitoring performance, while trust appeared to have little impact. These results provide further evidence for how operators trust and interact with automation, a topic that is relevant to the implementation of automated systems in a variety of human-machine systems such as aviation.
