The Experiment Research Of The Impact Of Self-control Resource Depletion On Decisions-making In Moral Dilemmas

With the rapid development of economy and society, the problem of moral dilemma has been becoming increasingly serious. People lose the confidence of moral conscience gradually, because these moralities are often associated with our own interests.Self-control is one of the most important psychological function for human, lack of which will lead pepole hard to think and act in a rational way, and may become the puppet of motion and impulsion,which often leads to bad consequences. While in the cases of self-control resource depletion, wether affect the selection trend when one is faced with a moral dilemma. This study first to investigate whether moral dilemma decision will consume the resources of self-control though dual task paradigm, which is to clarify the relationship between the moral dilemma decision and self control(Experiment 1); the study two is also through dual task paradigm, Thus exploring in the case of self – control resources depletion, the decision trend of individuals when they are in the face of moral dilemma situations. And we using ERPs technology explored the neural mechanism of the resourses of self-control affect on the moral decision-trend(Experiment 2). The main results are as follows:(1) Moral dilemma decision will lead to the losses of self-control resources;(2) Individuals are tend to do utilitarian moral decisions whether under the condition of high or the losses of self-control resources, but the high losses group are more tend to make moral decisions than the low losses group; compared with "impersonal" moral dilemma decision, one is more tend to make moral decisions when involving "individuals" moral dilemma;(3) Low losses group experience more negative emotions than high losses group;(4) According to the data analysis of ERPs, because of the insufficient activat of frontal area activated in high losses group.there is no enough resources to afford to attention control, conflict control and other information processing, thus affecting the subsequent decision-making behavior;Low losses group can weigh the pros and cons, considering the benefit maximization, and showed a more rational decision-making behavior.Finally, our study prospected of future research according to the lack of the research.
