Intrinsic motivation, extrinsic reinforcement, and inequity

Abstract: If a person who is intrinsically motivated to perform an activity begins to receive external reinforcement for the activity, what will happen to his intrinsic motivation? Previous studies and the present study indicate that money decreases intrinsic motivation, while verbal reinforcements tend to enhance intrinsic motivation. The beginning of a cognitive evaluation theory is discussed, and an apparently discrepant prediction between this theory and inequity theory is pointed out. It is argued, however, that the theories are not conceptually discrepant, and the present study gives support for this argument. It is possible to distinguish between two broad classes of motivation to perform an activity: intrinsic motivation and extrinsic motivation. A person is intrinsically motivated if he performs an activity for no apparent reward except the activity itself (cf. Berlyne, 1966; Hunt, 1965; White, 1959). Extrinsic motivation, on the other hand, refers to the performance of an activity because it leads to external rewards (e.g., status, approval, or passing grades). The question of interest in this study is whether there will be changes in a person's intrinsic motivation for an activity when he receives external rewards for performing that activity. Deci (1971) reported that external reinforcements do affect intrinsic motivation, and he suggested the initial elements of a cognitive evaluation theory to account for the changes in intrinsic motivation following an experience with extrinsic rewards. The theory focuses on a person's cognitive evaluation of an activity and the reasons for his engaging in the activity. It suggests that distinctions should be made among different kinds of external rewards, since a person's evaluation of different rewards may be different. In turn, this would 1 The author would like to thank Wayne Cascio for serving as the first experimenter and for helping with the data analysis; Victor Vroom for making helpful comments on an earlier draft of the manuscript; and Larry Coff for being the second experimenter.
