In the classroom the top +students get A's, and in the factory or office the best workers get +raises. It's an article of faith for most of us that rewards promote +better performance. + +But a growing body of research suggests that this law is not nearly as +ironclad as was once thought. Psychologists have been finding that +rewards can lower performance levels, especially when the performance +involves creativity. + +A related series of studies shows that intrinsic interest in a task - +the sense that something is worth doing for its own sake - typically +declines when someone is rewarded for doing it. + +If a reward - money, awards, praise, or winning a contest - comes to +be seen as the reason one is engaging in an activity, that activity +will be viewed as less enjoyable in its own right. + +With the exception of some behaviorists who doubt the very existence +of intrinsic motivation, these conclusions are now widely accepted +among psychologists. Taken together, they suggest we may unwittingly +be squelching interest and discouraging innovation among workers, +students and artists. + +The recognition that rewards can have counter-productive effects is +based on a variety of studies, which have come up with such findings +as these: Young children who are rewarded for drawing are less likely +to draw on their own that are children who draw just for the fun of +it. Teenagers offered rewards for playing word games enjoy the games +less and do not do as well as those who play with no rewards. +Employees who are praised for meeting a manager's expectations suffer +a drop in motivation. + +Much of the research on creativity and motivation has been performed +by Theresa Amabile, associate professor of psychology at Brandeis +University. In a paper published early last year on her most recent +study, she reported on experiments involving elementary school and +college students. Both groups were asked to make "silly" collages. +The young children were also asked to invent stories. + +The least-creative projects, as rated by several teachers, were done +by those students who had contracted for rewards. "It may be that +commissioned work will, in general, be less creative than work that is +done out of pure interest," Amabile said. + +In 1985, Amabile asked 72 creative writers at Brandeis and at Boston +University to write poetry. Some students then were given a list of +extrinsic (external) reasons for writing, such as impressing teachers, +making money and getting into graduate school, and were asked to think +about their own writing with respect to these reasons. Others were +given a list of intrinsic reasons: the enjoyment of playing with +words, satisfaction from self-expression, and so forth. A third group +was not given any list. All were then asked to do more writing. + +The results were clear. Students given the extrinsic reasons not only +wrote less creatively than the others, as judged by 12 independent +poets, but the quality of their work dropped significantly. Rewards, +Amabile says, have this destructive effect primarily with creative +tasks, including higher-level problem-solving. "The more complex the +activity, the more it's hurt by extrinsic reward," she said. + +But other research shows that artists are by no means the only ones +affected. + +In one study, girls in the fifth and sixth grades tutored younger +children much less effectively if they were promised free movie +tickets for teaching well. The study, by James Gabarino, now +president of Chicago's Erikson Institute for Advanced Studies in Child +Development, showed that tutors working for the reward took longer to +communicate ideas, got frustrated more easily, and did a poorer job in +the end than those who were not rewarded. + +Such findings call into question the widespread belief that money is +an effective and even necessary way to motivate people. They also +challenge the behaviorist assumption that any activity is more likely +to occur if it is rewarded. Amabile says her research "definitely +refutes the notion that creativity can be operantly conditioned." + +But Kenneth McGraw, associate professor of psychology at the +University of Mississippi, cautions that this does not mean +behaviorism itself has been invalidated. "The basic principles of +reinforcement and rewards certainly work, but in a restricted context" +- restricted, that is, to tasks that are not especially interesting. + +Researchers offer several explanations for their surprising findings +about rewards and performance. + +First, rewards encourage people to focus narrowly on a task, to do it +as quickly as possible and to take few risks. "If they feel that +'this is something I hve to get through to get the prize,' the're +going to be less creative," Amabile said. + +Second, people come to see themselves as being controlled by the +reward. They feel less autonomous, and this may interfere with +performance. "To the extent one's experience of being +self-determined is limited," said Richard Ryan, associate psychology +professor at the University of Rochester, "one's creativity will be +reduced as well." + +Finally, extrinsic rewards can erode intrinsic interest. People who +see themselves as working for money, approval or competitive success +find their tasks less pleasurable, and therefore do not do them as +well. + +The last explanation reflects 15 years of work by Ryan's mentor at the +University of Rochester, Edward Deci. In 1971, Deci showed that +"money may work to buy off one's intrinsic motivation for an activity" +on a long-term basis. Ten years later, Deci and his colleagues +demonstrated that trying to best others has the same effect. Students +who competed to solve a puzzle quickly were less likely than those who +were not competing to keep working at it once the experiment was over. + +Control plays role + +There is general agreement, however, that not all rewards have the +same effect. Offering a flat fee for participating in an experiment - +similar to an hourly wage in the workplace - usually does not reduce +intrinsic motivation. It is only when the rewards are based on +performing a given task or doing a good job at it - analogous to +piece-rate payment and bonuses, respectively - that the problem +develops. + +The key, then, lies in how a reward is experienced. If we come to +view ourselves as working to get something, we will no longer find +that activity worth doing in its own right. + +There is an old joke that nicely illustrates the principle. An +elderly man, harassed by the taunts of neighborhood children, finally +devises a scheme. He offered to pay each child a dollar if they would +all return Tuesday and yell their insults again. They did so eagerly +and received the money, but he told them he could only pay 25 cents on +Wednesday. When they returned, insulted him again and collected their +quarters, he informed them that Thursday's rate would be just a penny. +"Forget it," they said - and never taunted him again. + +Means to and end + +In a 1982 study, Stanford psychologist Mark L. Lepper showed that any +task, no matter how enjoyable it once seemed, would be devalued if it +were presented as a means rather than an end. He told a group of +preschoolers they could not engage in one activity they liked until +they first took part in another. Although they had enjoyed both +activities equally, the children came to dislike the task that was a +prerequisite for the other. + +It should not be surprising that when verbal feedback is experienced +as controlling, the effect on motivation can be similar to that of +payment. In a study of corporate employees, Ryan found that those who +were told, "Good, you're doing as you /should/" were "significantly +less intrinsically motivated than those who received feedback +informationally." + +There's a difference, Ryan says, between saying, "I'm giving you this +reward because I recognize the value of your work" and "You're getting +this reward because you've lived up to my standards." + +A different but related set of problems exists in the case of +creativity. Artists must make a living, of course, but Amabile +emphasizes that "the negative impact on creativity of working for +rewards can be minimized" by playing down the significance of these +rewards and trying not to use them in a controlling way. Creative +work, the research suggests, cannot be forced, but only allowed to +happen. + +/Alfie Kohn, a Cambridge, MA writer, is the author of "No Contest: The +Case Against Competition," recently published by Houghton Mifflin Co., +Boston, MA.
