45 The Effect of External Rewards on Behavior 外界奖励对行为的影响
①Psychologists take opposing views on how external rewards,from warm praise to cold cash, affect motivation and creativity. Behaviorists,who study the relation between actions and their consequences, argue that rewards can improve performance at work and school. Cognitive researchers,who study various aspects of mental life,maintain that rewards often destroy creativity by encouraging dependence on approval and gifts from others.
②The latter views has gained many supporters, especially among educators.But the careful use of small monetary rewards sparks creativity in grade-school children, suggesting that properly presented inducemens indeed aid inventiveness,according to a study in the June Journal of Personality and Social Psychology.
③"If kids know they're working for a reward and can focus on a relatively challenging task, they show the most creativity, "says Robert Eisenberger of the University of Delaware in Newark. "But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards.
④A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Eisenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore failing grades.
⑤In earlier grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points towards valued rewards, shows promise in raising effort and creativity,the Delaware psychologist claims.
