The case histories of five students enrolled in a university course in how to study are reported. The students ranged in age from 18 to 35, included two males and three females, and varied in school experience from no college in one case and some college in two cases to college degrees in two cases. Students were initially taught to chart their own study behavior using a textbook of their choice. Halfway through the course they were given instruction in techniques of behavior modification. They were assigned to a part of these self-selected techniques for their self-selected problems. The contingencies and payoffs were chosen by the student. Contracts were signed by each student and included such rewards as recreational reading time, listening to rock and roll music, and walking the dog. They included such avoidance contingencies as gaiting the dog, wearing a disliked sport coat, and nonsmoking. The behaviors to be changed included accelerating rate, increasing length of time spent studying, and beginning studying. In all cases the contingencies served to modify behavior toward the desired goal. A broader survey of study behavior under natural situations is suggested. Tables and a bibliography are included. (CM)
