心理学家的发现过度理由效应（Psychologist discovery excessive justification effect） An introduction to the experiment of excessive cause effect Social psychology said Overjustification effect is discovered by psychologist dessy. In 1971, dessy and his assistant using experimental method, proved a good Overjustification effect exists. He took college students as subjects and asked them to solve attractive intellectual problems individually. The experiment was divided into 3 stages: the first stage, each participant own problem-solving, not to reward; the second stage, subjects were divided into two groups, experimental group subjects each solve a problem to get paid $1; the third stage, the rest time is free, just do what. Objective to investigate whether subjects maintain interest in problem solving. The results showed that compared with the reward group, continue to solve the no reward group at rest, and the reward group while get paid when solving very hard and get paid time off in the not obvious, lose interest in solving problems. Money in experimental group during the second stage, as the external cause excessive reason, Overjustification effect obviously, the reward group trial reward to explain their problem-solving behavior, so that their interest in solving their attitude changed. At the third stage, the reward once lost, has changed the attitude of the subjects, no reward is no reason to continue solving, and control subjects on problem solving interest has not been Overjustification effect damage, therefore, the third stage continued enthusiasm on problem solving. This experiment shows that excessive reason will work on everyone. In order to make their actions seem reasonable, people always like to look for reasons for what happened. In the process of looking for reasons, it is often the first to look for the obvious. If the reason is sufficient to explain the behavior, people no longer seek it deeper.
