    What inspires kids to be creative and pursue academic excellence? Some teachers use rewards in recognition of students’ effort or achievement, giving them prizes, medals, certificates, or money.

Psychologists take opposite views of 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, believe 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(金钱的) rewards sparks creativity in primary school children, suggesting that properly given stimuli(刺激) indeed encourage creativity, according to a study in the June Journal of Personality and Social Psychology.

"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 desire for rewards."

A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with students lacking in creativity and motivation, Eisenberger says. As an example of the latter point, he particularly mentions growing efforts to tighten grading standards and adopt failing grades at major universities.

In earlier grades, the use of rewarding system, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, Eisenberger claims.
