The present study examined the effect of success and failure performance feedback
on perceived mental workload and monitoring performance in flight simulation task.
The revised version of the multi-attribute task battery (MATB) was administered on
20 non-pilot participants. The performances were recorded as hit rates, false alarms
and root mean square errors. Mental workload was assessed using NASA-TLX
questionnaire. A 2(success-failure feedback) x 2(30-min sessions) x 3(10-min
blocks) mixed factorial design with repeated measures on last two factors was
used. The obtained results revealed that performance feedback did not have a
significant effect on mental workload and malfunction detection. The findings
support the notion that monitoring inefficiency (i.e., automation-induced
complacency) is a robust phenomenon and it can be observed in multi-task
environment with high static automation reliability.
