Overjustification and Intermittent Reinforcement.
Stalling, Richard B.; And Others
Within the area of attribution theory, an overjustification effect is inferred if, following reward for an intrinsically interesting activity, individuals subsequently show less interest in that activity than comparable individuals who receive no reward. In an attempt to isolate the overjustification effect, 60 college students (30 male, 30 female) played 14 games of pinball with two eight-minute free periods before and after the games, in which subjects were told they could do as they wished. Subjects were assigned to one of six treatment conditions: no reward for playing pinball (intrinsic); a lump sum payment (noncontingent); feedback on a continuous or variable reinforcment schedule without payment (contingent feedback); or feedback on the same schedule with payment (contingent payment). An analysis of the results for amount of free time spent playing revealed no overjustification effect. Subjects given continuous feedback (paid or unpaid) liked the task more. Only variable reinforcement appeared to maintain play during a "free-choice" period. (Author/BL)
