Causality orientations moderate the undermining effect of rewards on intrinsic motivation

The present study tested the hypothesis that individual differences in autonomy or control causality orientation would moderate the undermining effect of rewards on intrinsic motivation. Equal numbers of autonomy- and control-orientated participants provided solutions to an interesting puzzle under reward or no reward conditions. Participants were then required to provide further solutions to the puzzle in a free-choice period. The time spent in solving the puzzle during the free-choice period constituted the dependent measure of intrinsic motivation. Results revealed a significant interaction effect of causality orientations and reward condition on intrinsic motivation. Control-oriented participants assigned to the reward condition exhibited significantly lower levels of intrinsic motivation compared to those assigned to the no reward condition. In contrast, there was no significant difference in intrinsic motivation levels across the reward conditions for autonomy-oriented individuals. Findings indicate that an autonomy-oriented causality orientation offered a degree of ‘protection’ from the undermining effect of rewards on intrinsic motivation. This is in keeping with self-determination theory in terms of the interactive effects of environmental events and interpersonal factors on intrinsic motivation.     

Effect of Reward Contingency on Intrinsic Motivation

The effects of type of task and type of reward contingency on intrinsic motivation for subsequent task performance were investigated. The sample consisted of 50 young Indian adults. The results showed a significantly greater amount of free choice time spent on a heuristic task rather than an algorithmic task. The verbal measures of intrinsic motivation yielded a significant effect of reward contingency with greater intrinsic motivation under performance-contingent reward, followed by task-contingent and no-reward conditions, respectively. The results support self-determination and competence processes as important mediators of intrinsic motivation.     

The Effects of Task Content and Reward Contingency Upon Task Performance and Satisfaction1

A laboratory study examined the effects of task design and reward contingency upon task performance and satisfaction and upon behavioral and attributional measures of intrinsic and extrinsic motivation. Intrinsic and extrinsic motivation were defined by the task content-task consequence distinction. Both the task design and reward contingency factors were found to yield significant multivariate F ratios, but their interaction was not significant. Subjects in the contingent pay condition had higher performance quantity than those in the noncontingent condition. Subjects in the enriched task condition produced higher quality units than those in the nonenriched condition. Both contingent pay and enriched task conditons yielded higher task satisfaction and increased attributions of performance to intrinsic factors. Results were discussed in terms of cognitive evaluation theory and the distinction between intrinsic and extrinsic motivation.     

The effect of earlier experience and reward contingencies on intrinsic motivation

The effects of task-contingent and performance-contingent extrinsic rewards upon subsequent intrinsic motivation are compared. Intrinsic motivation is measured by behavioral observation in a free time period and by rating scales. The results show, as expected, a higher rating of intrinsic motivation in the performance-contingent reward condition. The study further compares strength of intrinsic motivation in one- and two-session conditions. As hypothesized, a two-session condition, in which the subjects have a preexperience with the task without reward administration, leads to a higher rating of intrinsic motivation than a one-session condition without such a preexperience. The behavioral measure of intrinsic motivation is not significantly affected by the conditions. A post hoc analysis of the data indicates that there may be a different effect of extrinsic rewards on behavioral measures and on rating scale measures of intrinsic motivation.     

Increasing and decreasing intrinsic interest with contingent rewards: A test of cognitive evaluation theory

The study examined Deci's (Deci, E. L. Intrinsic motivation. New York: Plenum Press, 1975) hypotheses regarding the effects of contingent rewards on intrinsic task interest. Seventy-two male university students worked on a series of puzzles and were given either a high value reward ($1.50) or a low value reward ($.45). The money was given either contingent upon the simple execution of the task (task-contingent), contingent upon the ostensible attainment of a performance criterion level (criterion-contingent), or noncontingent and unexpected (control). Compared to the high payment control subjects, subjects who received the task-contingent high reward rated the task as less interesting, while subjects who received the criterion-contingent high reward rated it as more interesting. Also, subjects expressed less interest in the task after receiving the high task-contingent reward than the low task-contingent reward, but indicated greater interest after receiving the high criterion-contingent reward than the low criterion-contingent reward. It was concluded that substantial support was obtained for Deci's (1975) cognitive evaluation theory.     

Rewards,Intrinsic Motivation,and Creativity: A Case Study of Conceptual and Methodological Isolation

Three decades of research have failed to produce general agreement concerning the effects of reward on creativity. We believe that the problem stems not from any great complexity of research findings, but primarily from the clash between romantic and behaviorist worldviews concerning basic human nature. Isolation of these research camps has produced narrow perspectives and failures to correct persisting methodological flaws. Research correcting these flaws suggests that rewards for novel performance increase intrinsic motivation and creativity, whereas rewards for conventional performance decrease intrinsic motivation and creativity. Creative motivational orientation, enhanced by rewards, strongly affects innovative performance.     

The differential effects of tangible rewards and praise on intrinsic motivation: A comparison of cognitive evaluation theory and operant theory

Substantial research indicates that tangible rewards, such as money, prizes, and tokens, decrease response rates by undermining intrinsic motivation. In contrast, praise appears to increase response rates by enhancing intrinsic motivation. Based on their interpretation of available evidence, many social-cognitive researchers warn not to use tangible rewards in applied settings and to use praise instead. Furthermore, they suggest that the differential effects of the two types of rewards on intrinsic motivation cannot be explained using principles of operant psychology. Cognitive evaluation theory provides one of the most recent and widely cited social-cognitive explanations for the different effects of the two types of rewards on intrinsic motivation (Deci & Ryan, 1985). However, a review of existing research found little support for the explanations based on this theory and revealed three potential confounding effects: (a) temporal contiguity, (b) the number of reward administrations, and (c) discriminative stimuli associated with reward availability. These three confounding factors provide explanations for the effects of tangible rewards and praise on intrinsic motivation that are consistent with principles of operant psychology.     

Applying self-determination theory to understand the motivational impact of cash rewards: New evidence from lab experiments

We investigated, based on self-determination theory (SDT), the impact of the functional meaning of monetary rewards on individuals' motivation and performance and further tested the role of the psychological needs as the underlying mechanism. In two experimental studies, we show that when presented in an autonomy-supportive way, rewards lead participants to experience greater intrinsic motivation, which leads them to perform better, than when monetary rewards are presented in a controlling way. This is mediated by greater psychological need satisfaction, indicating that through greater feelings of competence, autonomy, and relatedness, individuals experience greater intrinsic motivation for the task at hand. Our findings suggest that rewards can have a distinct effect on individuals' motivation and performance depending on whether they take on an autonomy-supportive or controlling meaning, thus providing empirical evidence for the theoretical and practical implications of SDT's concept of functional meaning of rewards. By highlighting the importance of this concept, this research contributes to our understanding of the effectiveness of such rewards in the workplace, suggesting that they can foster employee motivation and performance if organisations present them to employees in an autonomy-supportive way to convey an informational meaning and positively contribute to their psychological need stisfaction.     

Intrinsic motivation,external reward,and their effect on overall motivation and performance

An unresolved debate lingers concerning the effect of performance-contingent rewards on motivation and performance. Behavioral psychology and economics suggest that performance-contingent rewards improve performance. In contrast, cognitive evaluation theory predicts that performance-contingent rewards undermine motivation and performance. We discuss the predictions of these two streams and develop an experiment that resolves the limitations of previous studies by using a new measure of intrinsic motivation: self-selection into a specific area of knowledge, as revealed by choice of academic major. Students from mathematics-related and literature-related areas were selected and randomly assigned to math and English language tests. Participants received a participation fee or a performance-contingent payment in addition to a fee. Both performance-contingent rewards and intrinsic motivation improved motivation and performance, in contrast with cognitive evaluation theory’s predictions.

Effects of social-psychological factors on creative performance: the role of informational and controlling expected evaluation and modeling experience

The impact of two social-psychological factors, expected evaluation and modeling, on creativity was investigated in a laboratory study. The controlling and informational aspects of expected evaluation were manipulated and individuals were provided no example, a standard example, or a creative example of a solution to a representative management problem. As expected, individuals had significantly higher creativity and intrinsic motivation when anticipating an informational rather than a controlling evaluation. In addition, individuals given a creative example had higher creative performance than those given no example. The lowest levels of intrinsic motivation and creativity were found when expected evaluation was of a controlling nature and a standard model was given. Additionally, we tested and found support for Cognitive Evaluation Theory's primary intervening cognitive process of locus of causality mediating the relationship between evaluation and intrinsic motivation. Intrinsic motivation was not found to mediate the relationship between evaluation and creativity, and possible explanations for this result are discussed.     

A process analysis of the effects of performance-contingent rewards on intrinsic motivation

In this study, the effects of performance-contingent rewards on intrinsic motivation were examined in comparison to no-reward controls receiving identical performance feedback. A path analytic process analysis was conducted to examine the mediation of reward effects on subsequent task interest. It was hypothesized that competence valuation, or the personal importance of doing well, would be an important mediator of interest in situations where performance feedback was available. Rewards were predicted to affect interest by influencing an individual's valuation of competence, and by altering the competence valuation mediation process. In addition, achievement orientation was hypothesized to interact with reward in affecting importance and the mediation process. Prior to performing an interesting puzzle, high school students were offered a performance-contingent reward, and then indicated how personally important it was to do well. After doing three puzzles, all subjects received positive feedback regarding their performance. Multiple regression analyses indicated that importance was affected by the experimental variables, and had a positive causal impact on subsequent intrinsic motivation. It was found that the promise of performance-contingent reward positively affected importance for low achievers relative to high achievers, and that the mediation of subsequent intrinsic interest by importance differed according to reward by achievement combinations. Additionally, a direct effect revealed that performance-contingent rewards significantly enhanced interest, relative to no-reward controls receiving identical performance feedback.     

Pervasive negative effects of rewards on intrinsic motivation: The myth continues

A major concern in psychology and education is that rewards decrease intrinsic motivation to perform activities. Over the past 30 years, more than 100 experimental studies have been conducted on this topic. In 1994, Cameron and Pierce conducted a meta-analysis of this literature and concluded that negative effects of reward were limited and could be easily prevented in applied settings. A more recent meta-analysis of the literature by Deci, Koestner, and Ryan (1999) shows pervasive negative effects of reward. The purpose of the present article is to resolve differences in previous meta-analytic findings and to provide a meta-analysis of rewards and intrinsic motivation that permits tests of competing theoretical explanations. Our results suggest that in general, rewards are not harmful to motivation to perform a task. Rewards given for low-interest tasks enhance free-choice intrinsic motivation. On high-interest tasks, verbal rewards produce positive effects on free-choice motivation and self-reported task interest. Negative effects are found on high-interest tasks when the rewards are tangible, expected (offered beforehand), and loosely tied to level of performance. When rewards are linked to level of performance, measures of intrinsic motivation increase or do not differ from a nonrewarded control group. Overall, the pattern of results indicates that reward contingencies do not have pervasive negative effects on intrinsic motivation. Theoretical and practical implications of the findings are addressed.     

The effect of causality orientations and positive competence-enhancing feedback on intrinsic motivation: A test of additive and interactive effects

Based on self-determination theory, this study investigated whether individual differences in autonomy or control causality orientation and positive competence-enhancing feedback have additive or interactive effects on intrinsic motivation. Autonomy- or control-oriented participants provided solutions to an interesting puzzle under conditions of positive competence-enhancing feedback or no feedback. Time spent solving the puzzle during a subsequent free-choice period constituted the dependent measure of intrinsic motivation. Autonomy-oriented individuals spent significantly longer on the puzzle than control-oriented participants regardless of feedback condition. Analogously, positive feedback increased time spent on the puzzle compared to no feedback regardless of causality orientation. Findings indicate that dispositional motivational orientations and feedback provided by social agents can enhance intrinsic motivation but the effects are additive rather than interactive.     

Intrinsic and Extrinsic Rewards and Motives: Replication and Extension with Kibbutz Workers1

Past experimental findings on the effects of externally mediated rewards on intrinsic motivation were explained on the basis of expectancy theory as a special case of the motivational effects on incentives. It was hypothesized that any reward object enhances its commensurate motive and weakens noncommensurate motives. The hypotheses were confirmed by means of partial correlational analyses of the relationships among intrinsic, status, and material rewards and motives measured in a survey of male kibbutz³ workers, providing constructive replication of experimental findings and supporting expectancy theory. The results were discussed with reference to motivation in general as well 3s practical implications for applied settings.     

Use of the maximal-operant principle to motivate children's intrinsic interest

The present research examined the hypothesis that in contrast to theory and research indicating that tangible reward decreases subsequent interest in enjoyable academic activities, rewards are perceived by adults as effective techniques to maximize long- and short-term subsequent interest for academic tasks of both high and low initial interest level. The results of our first three studies demonstrated that college students and parents view tangible reward as more effective than other less controlling techniques to enhance intrinsic motivation and value rewards more for intrinsically interesting academic behaviors in comparison with others (e.g., prosocial behaviors). Our fourth study supported the hypothesis that adults do not subscribe to the minimal-sufficiency analysis of increasing intrinsic motivation but prefer a maximal-operant principle in which the likelihood of producing long-term interest in academic tasks is assumed to vary positively with the size of a reward. Our fifth and sixth studies investigated illusory correlation as one mechanism that may perpetuate beliefs about the assumed positive relation between tangible reward and intrinsic interest in academic tasks.     

Intrinsic motivation and the effects of self-consciousness, self-awareness, and ego-involvement: An investigation of internally controlling styles

This study explored the relationships among dispositional self-consciousness, situationally induced-states of self-awareness, ego-involvement, and intrinsic motivation Cognitive evaluation theory, as applied to both the interpersonal and intrapersonal spheres, was used as the basis for making predictions about the effects of various types of self-focus Public self-consciousness, social anxiety, video surveillance and mirror manipulations of self-awareness, and induced ego-involvement were predicted and found to have negative effects on intrinsic motivation since all were hypothesized to involve controlling forms of regulation In contrast, dispositional private self-consciousness and a no-self-focus condition were both found to be unrelated to intrinsic motivation The relationship among these constructs and manipulations was discussed in the context of both Carver and Scheier's (1981) control theory and Deci and Ryan's (1985) motivation theory     

Intrinsic motivation as a function of extrinsic financial rewards and subjects'locus of control

Two studies investigating the effects of pay on the intrinsic motivation of subjects varying along the dimension of locus of control were conducted. It was hypothesized that internals, who should assign greater weight to the competency aspect of rewards they receive, would manifest increasing intrinsic motivation as pay increased. Externals, who should be more likely to focus on the controlling aspects of rewards, were expected to show decreases in intrinsic motivation as rewards increased. In Study 1, where both the controlling and competency aspects of the rewards offered were deliberately kept vague, the hypotheses were supported. In Study 2, where the controlling aspect of the pay offered was made salient by making pay contingent upon performance, high pay undermined the intrinsic motivation of both internals and externals. It was suggested that only when the controlling aspect of pay is not salient will the intrinsic motivation of externals and internals be differentially affected. Support for the hypothesis that internals and externals differentially weight available information when making causal attributions was also noted.
