The Effect of Selective and Total Sleep Loss on the CNV and Its Psychological and Physiological Correlates,
Abstract
The contingent negative variation (CNV) from the vertex was recorded, together with autonomic variables, vertical eye movements, and reaction time (RT), from two groups of 7 Naval trainees each. The subjects received the first stimulus (S1) which was either a 'high' or 'low' pitched tone, 4 sec before the second 'low' pitched tone (S2). With the high pitched S1, the subjects did not terminate the S2. With the low pitched S1, they were to terminate the S2 quickly as possible by closing a handheld switch. In half of the trials, the experimenter determined the rate of executing the RT task (a work-paced condition); in the remaining half, the subject performed the RT task at their own preferred pace (self-pacing). Results support the hypothesis that the CNV, but not the autonomic correlates, could be used as a reliable and sensitive measure of an altered brain capacity to maintain an attentive state.
