Twenty normal males were selected for the study. Criterion for selection was based on personality structure. Subjects were made to remain sleepless for at least 22 hours and then were administered one of a number of antifatigue medications. Hypotheses had been formulated predicting differential responses by the two personality types to the sleeplessness state and to the antifatigue medication. Partial confirmation of the hypotheses was obtained.
