12~17岁青少年的决策表现:基于爱荷华博弈任务

Performance of 12~17-year-old Adolescents in Iowa Game Task

青少年早期还是青少年后期具备优势决策的能力存在分歧。通过改编版的爱荷华博弈任务,探究12岁~17岁的青少年的决策表现,结果发现:在青少年早期个体已经具备了优势决策的能力,在青少年中期决策能力最好,而在青少年后期决策表现最差,这说明在整个青少年时期决策能力的发展并非是线性的;青少年倾向于选择损失频率低的纸牌,出现了显著的“B牌效应”。

In the past decade,the development characteristics of decision-making have aroused widespread concern of scholars at home and abroad.However,from the existing research results,there are still some problems.With regard to the decision-making performance of adolescents at diferent stages,some researchers believe that individuals have the ability to make superior decisions in early adoles-cence,but some researchers believe that decision-making ability is only available in later adolescents.Based on the adapted lowa game task,this paper explores the decision-making performance of 12~17-year-old adolescents.The results show that:in the early stage of adolescence,the individual has already possessed the ability of superior decision-making,the best decision-making ability is in the middle of adolescence,and the worst in the later stage of adolescence,which indicates that the development of decision-making ability is not linear in the whole adolescent period.Adolescents tend to choose the cards with low loss frequency.There existed a significant "B-card effect".
