In Praise of Praise
What the research does establish is that rewards can have either a positive, neutral, or negative effect on intrinsic motivation, depending on the type of reward and how it is given. In the words of Deci, the world's leading expert on the effect of rewards on intrinsic motivation, It is tempting to say either, “Rewards are good” or “Rewards are bad.” It turns out, however, that both statements are too general. Certain kinds of rewards, given in certain ways enhance intrinsic motivation; other kinds of rewards, given in other ways, erode intrinsic motivation. Thus, as educators, we need to dig deeper, to be more differentiated in our thinking about rewards and motivation. We want to avoid undermining intrinsic motivation, but the way to do that is not to avoid all positive feedback — rather we need to avoid giving certain kinds of rewards in certain kinds of ways. The Geometry ScenariosLet's contrast two scenarios:
Later we assess the intrinsic motivation of the two students. We want to determine how motivated the two students are to solve geometry problems when there are no extrinsic rewards, no tokens, or candy. We test the students in two ways: 1) we give them a free choice to do more problems on their own; and 2) we ask them how much they like solving geometry problems, how The tokens motivated the student in the moment, and may have even caused the student to do more problems than otherwise, but when the tokens were absent the motivation was less than if no tokens had been given. Why is this important? If our only goal were to get the student to solve geometry problems, we might well persist in giving tokens and rewards. But as educators we have a higher goal: we want to promote intrinsic motivation, to promote a love of learning, to foster life-long learners. With the change rate rapidly increasing, only students who are motivated to continue learning on their own will compete well in the job world of tomorrow. Intrinsic motivation predicts life-long success. How can we explain why the tokens decreased intrinsic motivation while the praise increased intrinsic motivation? If we understand three key concepts, we can go a long way toward understanding which rewards and which way of giving rewards will increase or decrease intrinsic motivation. Three Key ConceptsAs teachers, if we are to foster the love of learning and have students who want to learn on their own, we need to understand the relation of rewards and intrinsic motivation. Three key concepts are critical for understanding what kind of rewards lead to increased intrinsic motivation v. decreased intrinsic motivation. These concepts are attribution shift, perceived competence, and perceived interest. Attribution Shift. An attribution shift describes a shift in what we think is the cause of behavior. The critical question: Why am I performing? The student in Scenario 1 did not experience an attribution shift. If asked why she/he was doing geometry problems, the student would respond, I enjoy doing the problems. The student in Scenario 2, in contrast experienced an attribution shift. Before the tokens were introduced, the student did the problems for the pleasure of solving the problems. After consistently receiving tokens for doing the problems, the student began to solve the problems for the tokens. If asked at that point why she was doing geometry problems, the student would say, “To earn tokens.” There was an attribution shift. Before the tokens were introduced the student attributed her motivation to the pleasure intrinsic in the task; after receiving tokens for each problem, the student attributed her motivation to the tokens, to rewards extrinsic to the task. When the tokens were later taken away, the student found less reason to do problems. She was working for tokens, not for the pleasure of solving problems, so when there were no tokens, there was less reason to solve the problems. Extrinsic rewards can cause a attribution shift that erodes intrinsic motivation. We may ask, “Well, isn't a compliment a reward? Why did the praise not erode intrinsic motivation?” The research has shown that verbal praise tends to increase intrinsic motivation, not decrease it. There are several plausible explanations. The first explanation is that verbal praise is usually unexpected. Note, the student did not know the teacher was going to walk by and drop a compliment. So the student could not think she was doing the problems for the praise. There are other reasons why verbal praise has the opposite effect as expected, tangible rewards, and we will get to them as we explain the remaining two key concepts.
If I doubt that I can succeed, my perceived competence is low and I am less likely to tackle a learning task or persist in the face of difficulty. If my perceived competence is high, I will more likely try to master difficult tasks and persist in the face of difficulty. To some extent then, perceived competence creates a self-fulfilling prophecy: When I feel competent in a task, I persist in the face of difficulty, and complete the task, fulfilling my prophecy; when I don't feel competent, I don't persist, fulfilling that prophecy. We live up to, or down to, our own expectations. Competence shifts, changes in your perceived competence, help explain intrinsic motivation. If someone tells you that you are good at something, and that increases how competent you feel, your perceived competence has shifted. Anything that makes your feel more competent in a task increases your motivation to engage in the task, especially as task difficulty increases. This goes part way toward explaining why the praise in Scenario 1 increased intrinsic motivation whereas the tokens in Scenario 2 decreased intrinsic motivation. The student receiving the praise, “You are really great at that” probably felt a bit more competent afterwards. In contrast, the student who received tokens to perform the task, might well have felt a bit less competent, concluding, “I must not be that great at this if the teacher needs to bribe me to do the problems.” Task Interest Shift. Task interest describes how intrinsically interesting or motivating a task appears. The critical question: Does this task look interesting? If someone says, “That task is boring,” or we begin a task and find it is not challenging or interesting, our perceived interest in the task likely decreases. If someone says, “That task is challenging and fun,” or as we begin a task we find it keeps our interest, our perceived interest in the task likely increases. Task interest shifts are the third key to explaining the different impact of the verbal comment and the tokens in Scenarios 1 and 2. In Scenario 1, when the teacher said, “You are really fully engaged,” the student became more aware of how interested she was in the geometry problems. Anything that shifts task interest so a student perceives a task as more interesting, by definition increases intrinsic motivation. In contrast, if a teacher offers tokens to perform a task, the student is likely to think, “This task must be boring if the teacher needs to offer bribes to get me to do it.” Having decreased task interest in this way, there is less motivation to do the task later when the tokens are absent. Three Critical QuestionsGiven that some kinds of rewards and some ways of giving rewards will make learning more intrinsically interesting while other ways will make learning less intrinsically motivating, as educators we need to ask the critical questions:
We need to know which rewards and which ways of giving them undermine intrinsic motivation and which rewards bolster intrinsic motivation. What the Research Tells UsAnalysis of hundreds of carefully designed research studies on the relation of reward to motivation gives us clear answers to our critical questions. To cull out the reliable findings from among the hundreds of studies, researchers have turned to meta-analyses — studies that look at which findings hold up across the many studies conducted to date. One meta-analysis not only examined 128 studies; it examined the consistency of findings across various meta-analyses!5 The general finding across all of these studies indicates that only certain kinds of rewards, given in certain ways, erode intrinsic motivation. Others have no effect. And some actually have a positive effect. The results of these studies are summarized in the Table: Rewards and Intrinsic Motivation.
Interpretation of ResultsThese results can be predicted and understood based on the three key concepts: Attribution Shift, Perceived Competence, and Perceived Task Interest. Rewards that Erode Intrinsic Motivation• Engagement-Contingent, Tangible Rewards Example: A teacher says, “I will give you a gold star when you begin working on your math worksheet.” • Completion-Contingent, Tangible Rewards Example: A teacher says, “I will give you a piece of candy when you complete your math worksheet.”
Example: We say to our class, when we grade the homework, the team with the highest total scores will get to line up first for recess (or get points toward recognition or reward). There are other ways competitive rewards undermine motivation. When we pit students against each other we create winners and losers. With eight teams in the class, each team knows the probability of winning is slim. Further, after not winning for several rounds, students begin making defensive attributions: “We didn't care about doing well.” Why? It is much easier to say, “I don't care” than to say, “I really would like to win, but can't.” In addition, we undermine motivation when we set students against each other because we erode peer support. Each team knows the other teams are not hoping for their success. This is quite in contrast to cooperative reward situations in which the whole class receives a reward if the sum of all the scores is high. In that case, each student is buoyed by the support of all the others; everyone wants everyone else to do as well as possible. Rewards that Neither Increase nor Decrease Intrinsic Motivation• Unexpected Rewards Example: The teacher says, “I know you were not expecting it, but since you did so well on that assignment, everyone will get to play a Silly Sport!” • Rewards for Otherwise Boring Tasks Example: The teacher has a learning task the teacher knows is not at all interesting for any of the students and says, “You will each receive points for completing this task.” Note: The same exact words, “You will each receive points for completing this task,” will have a different impact on intrinsic motivation depending on whether or not the task is intrinsically interesting to begin with! The effect of rewards on boring tasks will depend in part on whether or not once they engage in the tasks students will discover interest in the tasks. In some situations, extrinsic rewards can increase motivation for otherwise uninteresting tasks. Why? The reward can induce the student to engage in a task they otherwise might not perform. The student may then discover intrinsic rewards in the task. For example, a student may perform what appears to be a boring math worksheet only in hopes of an extrinsic reward, but then while doing the problems discovers she actually is skilled in that kind of problem and enjoys solving the problems.
• Rewards Not Contingent on Task Performance Example: The teacher brings in a treat for the class, saying, “I thought it would be fun for us to all enjoy a treat today.” Non-contingent rewards, however, may make class more interesting and may change students' perception of the teacher. Because they are unexpected, non-contingent rewards create novelty. Further, they increase liking for the teacher and make for a more positive class tone — all of which may have a favorable impact on learning. Rewards that Increase Intrinsic Motivation• Positive feedback and praise Example: The teacher walks by while a student is working on a worksheet and says, “Your topic sentences are very descriptive.” “That is a creative proof.” or “You are really fully focused on your work.” Further, when the teacher tells the student their topic sentences are very descriptive, their handwriting is clear, or their proof is creative, it is likely their perceived competence will increase, which increases intrinsic motivation. When the teacher tells the student they are fully focused on a task, it is likely the student's perceived task interest increases. The student thinks, “If I am really fully engaged by this task, the task must be interesting.” The praise is not perceived as an attempt to control their behavior, but rather communication about their competence, or about their level of interest. An important distinction: Praise can be evaluative or descriptive. Evaluative praise (Great job! Excellent! You are good at that!) runs the risk of establishing the teacher as the locus of evaluation, disempowering the student. The teacher, not the student, is the judge. Evaluative praise communicates the feelings of the teacher; it is subjective. In contrast, descriptive praise communicates something about the work (You capitalized all the proper nouns. You supported your hypothesis with three types of research! You showed all your work on those algebra problems.) It communicates appreciation by the teacher, but it is objective feedback, allowing the student to self-evaluate. With evaluative praise, students are more likely to become extrinsically motivated, working for the praise of the teacher. With descriptive praise, students are more likely to become intrinsically motivated, working toward excellence.
