Abstract
Mildly mentally retarded adults were compared on both an auditory and a visual vigilance task with subjects having greater than average intelligence. No difference was found in the rate of decline of performance between the 2 groups in either of the 2 tasks, although overall performance of the above-average group was superior to that of the retarded group. The hypothesis that mentally retarded persons suffer from a more rapid decay in arousal under conditions of reduced sensory variation was not supported, nor was the suggestion that retarded subjects would demonstrate more inattention than would nonretarded subjects.
