Abstract
Used a reaction time (RT) task of short duration, characterized by a high signal rate (16 signals/min) to examine if 1 night of sleep deprivation (SD) in interaction with task duration would transfer and/or change the RT distribution. 5 male and 3 female undergraduates participated on 2 occasions: after SD and after normal sleep. From a significant interaction between SD and task duration for 25th, 50th, and 75th percentiles, it is concluded that there was a general increase in RT. Strengthening of the interaction for the 75th percentile values and significantly more blockings for the last minutes in SD also confirmed an increased skewness found by other researchers. Since these effects are a function of interaction, it is suggested that 1 of the effects of SD can be an accentuation of the decrement found in vigilance.
