亲社会情境对风险决策行为的影响
|
Abstract:
成年人的控制系统发育成熟，决策趋于理性。但成人在亲社会情境下如何整合风险决策中概率相关的信息并推动亲社会决策值得探讨。因此，我们选用了一个概率赌博任务范式，创设了相应的亲社会情境，探究了成人在不同概率水平下的风险行为调整。结果表明：成人在亲社会情境中，在输赢概率相当(即输/赢 = 50/45；输/赢 = 54/36)的条件下，会更加依赖于前一试次的反馈结果来减少下一试次中选赌的次数。
The control system of adults is mature and decision-making tends to be rational. However, it is worth discussing how adults integrate the information related to probability in risk-taking beha-vior and promote prosocial decision-making in prosocial context. Therefore, we tested a proba-bilistic gambling task, created a corresponding prosocial situation, and explored the risk-taking behavior adjustment of adults at different percentages. The results show that in the prosocial situation, adults will rely more on the feedback results of the previous trial to reduce the number of bets in the next trial when the probability of winning or losing is equal (that is, losing/winning = 50/45; losing/winning = 54/36).
