短文:Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study there 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. The latter view 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 inducements indeed aid inventiveness, according to a study in the June Journal of Personality and Social Psychology. "If kids know theyre working for a reward and can focus on a relatively challenging task, they show the most creativity," say Robert Eisenberger of the University of Delaware in Newark. "But its easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards." A 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. In earlier grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims.急求这篇短文的能够“读得通”的中文翻译,谢谢!!如果是直接从翻译网址上拉下来的完全读不通的翻译请不要贴上来,谢谢大家了!!!
