Peak Activation Time,Extraversion,and Students' Achievement

Abstract

Ninety-five men and women enrolled in three sections of a junior course on organizational behavior were differentiated with respect to peak activation time, extraversion, sleep patterns, and cumulative grade point average. Analyses indicate that those 19 most alert in the morning awoke earlier in the day, went to bed earlier at night, and had higher grade point averages than those 36 most alert in the afternoon or in the evening. Those most alert in the morning appeared to be more introverted than those most alert in the afternoon, who seemed to be more introverted than those most alert in the evening.
