单选题{{B}}D{{/B}} Psychologists take opposing 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(认识派的)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(金钱的)rewards sparks creativity in grade-school children, suggesting that properly presented inducements(刺激)indeed aid inventiveness, 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 Eisenhower of the University of Delaware in Newark. "But it's easy to kill creativity by giving rewards for poor performance of 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, Eisenhower 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 taken 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.

Yes, it's always nice to have someone help you when you're cooking. But this voice is not from a man. You are alone! Then where does it come from? Is it from a ghost? No, this isn't a ghost kitchen -- it's the kitchen of the future. Scientists are working to improve everything in the kitchen, from fridges to tables, and even the way we cook. They are making a system. It will help a person cook a meal. You do not need cookbooks. You can hear how to cook food. The fridge of the smart kitchen has a scanner. It looks at the foods in the fridge. It will order more milk from the store when your milk has gone bad or there is no more in the fridge. The gloves will test the temperature of everything they touch and say, "Need to cook longer" or "Hot and ready to eat". If you leave them on the stove by mistake, you'll hear they say, "Fire!" Even the knives and spoons will speak. For example, if you food is had, the knives and spoons will tell you not to eat it. The future may look wonderful, but it's not cheap. The multimedia fridge costs about 8 000 dollars. So even though high-tech kitchens are no longer a dream, not everyone can afford it.
