Alcohol, reaction time, and vigilance settings: importance of length of intersignal interval.
An experiment tested the hypothesis that a small dose of alcohol will produce a faster increase in simple auditory reaction time with time on task and increase over-all mean number of and over-all mean duration of extreme long reactions more than a zero-alcohol dose if signal frequency is low. The hypothesis was confirmed and theoretical and practical implications were discussed.
