Sleep Deprivation Effects on Responses to Signals of Unequal Probability in an Artifically Electrically Charged Environment

摘要

Young male subjects made repeated runs on a step-tracking task over a period of 48 hours during which they were deprived of sleep. Successive runs showed a reaction time (but not error rate) increase that was inversely related to signal probability, and a movement time increase that was related to distance travelled. Both effects were more evident on machine-paced than subject-paced tracking. There was no evidence that performance deterioration could be modified by the use of a patented anti-fatigue device.
