| It has been six years since the Pengyu case happened in2006, and it still smarting. At that time, no one could tell that this would be a template that people express apathy for a long period of time. Even though when the final trial result came out, we still cannot realize that. It seems to be a reincarnation of Pengyu case when the Xiaoyueyue case happened five years after that. The same things happened, with different encounters and radically different results. Even in the years of wartime, things would not be so tragical like that. And who on earth leaded to this tragedy? And what kind of factors made us choose to be silent and ruthless? No matter what kinds of these two tragedies, law event or moral thing, we should torture ourselves.After a brief overview of Pengyu and Xiaoyueyue case, this paper expounds the attitude and opinion of public. Then we discuss and analyze the changes of some informal groups’attitude to related events. The paper mainly use the Case analysis and Literature review method to probe into the cases and with aid of some classical social psychological experiment as evidence to reach the conclusion: Why did they choose to be immoral people after Pengyu case and how could they find their real egos after Xiaoyueyue event.This article starts emphatically from social psychology and quotes several social psychological theories to deeply analyze the informal group. Such as the cognitive dissonance theory of Leon Festinger, it says that people would try to find a new internal balance when the cognitive dissonance appears. And the main methods to do that are:reducing incongruous cognitive factors; increasing the congruous cognitive factors; introducing new cognitive factors, etc. This theory can better explain why some informal group chose the immoral behaviors when the cognitive dissonance happened after Pengyu case. And one of the most important theories of cognitive psychology:schema. It says that a lot of knowledge exist in our brain as schemas, people tend to use these schemas to guide their lives. The schema can make us to better observe and understand the new environment so as to better adapt to the new life. But it is easy to lead us to a undifferentiated and simple life. For Pengyu case and its subsequent cases, some informal group formed a schema of them, or a fixed way of thinking, and showed their indifference attitude to the similar events and resulted in the Xiaoyueyue tragedy.By using these theories, we find that some common senses are not completely correct. Such as a person’s attitude cannot well predict his behavior. On the contrary, a person’s behavior is not necessarily closely related with his attitude. As we know, humans are very good at finding excuses for their behaviors. So only through the analysis of social psychology can we better understand the mentality of the parties and bystanders.At the end of this paper, the author proposes some suggestions to the socialization of bystander effect caused by the Pengyu and Xiaoyueyue case, which are still based on social psychology. In the role-playing experiment, we found that repeated behaviors can affect a person’s attitude. It means that our attitude will be more inclined to the role or the behavior, in other words, will tend to accept the role’s characters or the nature of the behavior by playing such role or doing such things repeatedly. Consequently, we can try to lead the informal group to do some simple moral things, and then gradually change their attitude to moral. At the same time, we can learn from the butterfly effect caused by the Pengyu and Xiaoyueyue case that we should use the butterfly effect to promote altruism. By establishing altruism examples and eliminating the worries of prosocial behavior, we could lead the informal group to accept altruism and gradually make the altruism to be a part of the socialization of informal group. |
