“…Future studies can examine the applicability of countermeasures to complacency, such as variable-priority training (Kramer et al, 1995;Metzger et al, 2000) and adaptive task allocation strategies (Parasuraman et al, 1996) since it is uncertain whether these strategies would benefit seniors. Additional research should also examine trust and reliance of automation with older adults under less stressful conditions than the present experiment and in more realistic ecologically valid conditions.…”

The present study examined age differences in trust and reliance of an automated decision aid. In Experiment 1, older and younger participants performed a simple mathematical task concurrent with a simulated medication management task. The decision aid was designed to facilitate medication management, but with varying reliability. Trust, self-confidence and usage of the aid were measured. The results indicated that older adults had greater trust in the aid and were less confident in their performance, but they did not calibrate trust differently than younger adults. In Experiment 2, a variant of the same task was used to investigate whether older adults are subject to over-reliance on the automation. Differences in omission and commission errors were examined. The results indicated that older adults were more reliant on the decision aid and committed more automationrelated errors. A signal detection analyses indicated that older adults were less sensitive to automation failures. Results are discussed with respect to the perceptual and cognitive factors that influence age differences in the use of fallible automation. q

“…Compared with fixed, equalpriority training (50% and 50%), variable-priority training results in faster acquisition of dualtask skills. Accordingly, Metzger, Duley, Abbas, and Parasuraman (2000) trained participants in the three subtasks of the MATB using either the variable-or the fixed-priority method and examined both overall performance and detection of failures in the automated task (complacency). Variable-priority training led to better multitasking performance, and a trend for a reduction in the automation complacency effect was observed.…”

“…In the nautical environment, watchkeepers are increasingly responsible for secondary task functions such as engine and cargo control, in addition to the primary task of navigation. This requires that cognitive resources are deployed across several tasks to maintain overall performance (Metzger et al 2000). In addition to the dramatic increase in monitoring load and the overheads of managing divided cognitive resources, the need to control a broader range of engineering functions also places new demands on the knowledge and skills of the watchkeeper (Lee and Sanquist 1996).…”

Effects of display design on performance in a simulated ship navigation environment

Although automation is playing an increasing role on the ship's bridge, empirical research on the eVectiveness of alternative bridge designs is limited. In this paper, we describe an experimental study of the bene®ts of integrated information display, using a computerized simulation of a highly automated ship's bridge. The study compared three types of interface design, which presented radar and electronic chart information to the operator in diVerent ways: (a) integrated display, (b) functionally-separate display, and (c) spatiallyseparate display. EVects were examined in relation to time on watch and scenario complexity. Following extensive training on the task, 39 participants were tested over a 4-h experimental session, during which they encountered a sequence of collision scenarios of varying complexity. Using a dual-task methodology, a range of measures of primary and secondary task performance were taken, together with assessment of information sampling behaviour and subjective operator state (workload, fatigue, anxiety and situation awareness). The results indicated slight navigational advantages of the integrated display over the two alternative display types, although it also incurred higher levels of operator cost, particularly fatigue. There were no marked eVects of time on watch, but more complex scenarios were associated with impaired performance, increased workload and reduced situation awareness. Overall, the ®ndings have suggested some bene®ts of integrating primary information sources in a ship's bridge environment. The study further con®rms the value of experimental simulations as tools for investigating design issues for ship's bridge automation.
