30 Ss participated in an auditory vigilance task, time-shared with a memory task. The results showed no change in memory whether assessed independently or time-shared with the vigilance task. The vigilance performance demonstrated the classical vigilance decrement. Ss performing the vigilance task time-shared with the memory task performed significantly more poorly than Ss performing the vigilance independently of the memory task. Theoretical implications are suggested.
