摘要:

为探讨利己/利他不同情景是否会影响高社交焦虑个体的风险决策行为,本研究招募了90名大学生,通过使用改编的气球模拟决策范式、演讲任务和视频唤起情绪,考察不同社交焦虑水平(高、低)的大学生在不同情景(利己、利他)下,面对风险决策时的状态焦虑水平和做出的决策行为。结果发现,高社交焦虑个体的状态焦虑水平高于低社交焦虑个体。相较于对照组,高社交焦虑个体在利己情景下表现出风险回避,但在利他情景下减少了风险回避行为。研究结果验证了利他行为可以减少社交焦虑个体的风险回避行为,但并非通过降低状态焦虑水平。

Abstract:

To examine whether altruistic versus self-interest contexts differentially influence risk decision-making in individuals with high social anxiety (HSA), the present study recruited 90 college students. Using an adapted Balloon Analogue Risk Task (BART), a speech task, and emotional video stimuli, the study compared state anxiety levels and risk-related decision-making behaviors between HSA and low social anxiety (LSA) groups under self-interest and altruistic conditions. Results showed that individuals with HSA exhibited higher state anxiety than those with LSA. Compared to the LSA group, HSA individuals displayed risk-avoidance behavior in self-interest contexts but reduced such avoidance in altruistic contexts. These findings suggest that altruistic behavior can reduce risk avoidance in socially anxious individuals, though such effect is not mediated by a reduction in state anxiety. The underlying mechanisms require further investigation.
