An adaptive vigilance task with knowledge of results.
Hum Factors 1974 Aug; 16(4):333-338
The feasibility of adaptive vigilance tasks is examined in four groups of subjects who performed a 48 minute, computer controlled, visual watch keeping task, by employing the immediate feedback of knowledge of results as a treatment variable. Under non-adaptive conditions, the knowledge of results group showed the usual superiority in detection rate over the non-knowledge of results group, and made fewer commissive errors. Under adaptive conditions, the resulting curves for the adaptive variable yielded by 2 similar groups closely resembled the traditional performance measure, detection rate.
