Computer-aided system or automation technology is a pervasive phenomenon,
which confronts inexorably human issues of cognitive functioning. Automation
envisages the thought of electronic replacement of human operator. It plays a
critical role in situations when a small number of operators must control and
supervise a very complex set of remote processes. The present review examines
the notion of automated complacency and mental workload along with the factors,
which promotes or confines the effective usage of automation by human operators.
The concomitant effects of extended training, automation reliability and feedback
on the detection of automation failures and perceived workload in multitask
ambience have been studied and demonstrated in this paper. A long tenure of
training administered to the subjects indicated no benefit in terms of monitoring
efficiency and mental workload in the multitask ambience as well as results also
deciphered that varying feedback types failed to diminish mental workload, causing
detection inefficiency. The underlying mechanism of adaptive automation is also
considered within the framework of psychophysiological (HRV, pulse rate, EEG)
