The once always regarded as the most effective method of teaching, was already proven to be in effective by many psychologists. These baffling results had proved the famous behaviorist, B.F. Skinner, wrong GREATLY! In one of the experiments conducted, children were splitted into 2 groups. They were asked to drink a cup of yogurt. One group was pre-informed that they would receive a movie ticket if they drinked it. The other group was not given any rewards at all. In the end, only the group that was NOT given any rewards continued drinking yogurt. Main ReasonS for the the INEFFECTIVENESS of rewards or punishments 1.Rewards discriminate. When someone is offered rewards for doing sth (something), the rewarder is also implying that the person cannot handle that task. 2.Rewards ignore reason When a girl is reluctant to sleep, her parents would most likely to bribe her. However, as you can clearly see, her parents didn't bother to find out why is their daughter refusing to sleep. What I find very disturbing is the fact that most parents, teachers, or managers just blindly use rewards to bribe them into doing what they want. This is one of the reason for the growing number in aggressive teenagers. 3.Rewards tear apart relationships Imagine yourself as one of the students in a nursery class. Your teacher, Serena, walks into the classroom and announces,"Let's play a game! Anyone who answers my question correctly will get one sticker!" Then everyone began "snatching" for the stickers & the teacher's praise. How would you feel as a child? Everyone around suddenly becomes your potential obstacle to getting the merits. What's worse is that if someone starts bragging how much sticker they have. If you are a student who got the fewest number, you would feel no different from enduring a punishment!!! This is also comparable to a competition training, esp in sports, the only way to obtain the "Best Sports Man" title is to beat the others and they instantly morph into "hazardous aliens". NO COOPERATION CAN EXIST IN THIS KIND OF ENVIROMENT. 4.Rewards blast away any potential interest in the task Whenever we say, "Do this and you will get that!", we are, in fact, telling someone in another way that "that" is better than "this"! So she or he would lose interest in doing "this". I guess you might conclude that she or he's interest in "that" would rise. NO, she or he's interest in "that" would still "stick" to the same before the rewarding. 5.Rewards control the person When we reward someone, we are blasting out louder than the loudest on Earth speakers," I'm the BOSS!" This unsymmetrical balance would cause friendships to vaporize automatically. 6.Their intention to continue doing what we wanted CRUMBLES without rewards! As I mentioned earlier in the experiment example, the rewarded group of children didn't continue consuming yogurt without rewards. Furthermore, their interest "zonked" well below the interest of the unrewarded children!! PHP: In other words, rewards = punishments = "controllings" = DESTRUCTIVE!!!
