Behavioral Research On Adolescents' Fuzzy Decision Making And Risk Decision Making

Evaluating outcomes by comparing to various solution is a common used feature of human decision making.Comparing yourself with others in some circumstances,as a way of comparision,is often called social comparison.Individuals usually assess themselves by social comparision,and this way ordinarily affect their choices.Among all age of people,teenagers are more likely to take risks.They are immature,sensitive,and easily affect by social circumstances.Both parents and teachers always compare adolescents’ academic performance with that of others.Besides,adolescents are also inclined to compare themselves with others in all aspects.The earlier experimental studies indicate that the peer is the main compared objects when adolescents are making comparision.What’s more,adolescents will take more risks when they are together with the peer.This is known as the peer effect.However,when teenagers are facing different tasks,what will happen about their behavior if they compare themselves with the peer ?This study not only combine social comparison with decision-making,but divide decision scenarios into ambiguity and risk conditions.Adolescents are regarded as subjects in this study.The aim is to investigate the effects of different types of social comparison and the effects of different types of prior outcomes on the adolescents.To achieve the goal,this study includes two parts:Experiment 1 investigate that how social comparison influences adolescents’ decision-making in ambiguous.Experiment 1 take advantage of the Iowa Gambling Task,and the results are as follows:(1)Social comparison has no effect on adolescents’ decision-making risk,but upward comparison group switch decks more likely than downward comparison group.Adolescents prefer disadvantageous decks to advantageous decks and are more likely to gamble after gains.They prefer advantageous decks to disadvantageous decks and are less likely to gamble after losses.Adolescents switch decks more likely after a loss than after a gain.During the experimental process,the frequency of adolescents’ response-switching is gradually reducing.According to the experiment,it is demonstrated that they have a clear preference on Deck B.Experiment 2 investigate that how social comparison influences adolescents’ decision-making in risky.Experiment 2 take advantage of the Cambridgegambling task,and the results are as follows:when adolescents are facing upward comparison,they tend to take more risks,and when teenagers are facing downward comparison,they tend to take less risks.After a gain,adolescents tend to take more risks.While they tend to take less risk after a loss.But prior outcomes have no effect on the rational risk index.In general,social comparison has no effect on fuzzy decision-making,but it affects risk decision-making.Adolescents are more likely to seek risk in the context of upward comparison,and are more likely to avoid risk avoidance in downward comparison.Previous results have an impact on both fuzzy decision making and risk decision making,and previous gains tend to seek risk,and previous losses tend to risk aversion.Adolescents have different decision-making strategies that face different decision-making scenarios and have the ability to solve problems independently.
