Two groups of undergraduates, identified as high scorers (n = 24) or low scorers (n = 23) on the Study Habits section of the Survey of Study Habits and Attitudes, were administered alternate forms of the Wonderlic Personnel Test on two occasions, one with limited and one with unlimited time. Since high-scoring subjects performed better than low scorers on both timed forms but more so with limited time, and since they attempted more questions (limited) and were faster (unlimited), it was concluded that the superiority of students with high scores on study habits is based on both power and speed.
