专业类型在特里尔社会应激影响风险决策中的调节作用

The Regulating Role of Major Types in Risk Decision-Making Affected by Trier Social Stress Test

目的:探讨专业类型在特里尔社会应激影响风险决策中的调节作用。方法:62大学生分为应激组(n=30)和对照组(n=32),应激组采用特里尔社会应激测试(TSST)诱发急性心理应激感,对照组不做处理,2组大学生分别完成仿真气球模拟任务(BART)作为测试风险决策行为的指标;比较2组大学生风险决策行为得分,分析专业类型与组别的交互作用在风险决策行为上的差异。结果:应激组大学生的风险决策行为得分高于对照组,差异有统计学意义(t=2.44,P<0.05);不同组别与专业类型学生风险决策行为的交互作用显著(F=3.83,P<0.05),交互作用的简单效应分析结果显示,应激组中理科学生风险寻求上的得分高于文科学生(F=11.59,P<0.05),对照组中文科与理科学生风险寻求上的得分差异无统计学意义(F=0.540,P=0.586)。结论:急性心理应激能激发大学生个体更愿意选择冒险的倾向,但受到专业类型的调节。

Objective:To investigate the regulating effect of major types in risk decision-making process affected by Trier Social Stress Test.Method:62 college students were divided into stress group(n=30)and control group(n=32).The stress group was asked to perform Trier Social Stress Test which was to induce acute psychological stress,while nothing exerted over the control group.Then the two groups completed the Balloon Analogue Risk Task as an index to test the risk decision behavior.Scores of risk decision-making behavior of the two groups were compared and the differences of the interaction between major types and groups in risk decision-making behavior were analyzed.Results:The score of risk decision-making behavior in stress group was significantly higher than that in control group(t=2.44,P<0.05).The interaction between major types and groups was significant(F(1,57)=11.59,P<0.05).The simple effect analysis showed that the score of decision-making behavior from science students was significantly higher than arts students in the stress group,(F(1,57)=11.59,P<0.05),but not in the control group.The results of simple effect analysis of interaction showed that the score of risk seeking of science students in stress group was significantly higher than that of liberal arts students(F=11.59,P<0.05),but there was no significant difference between science and liberal arts students in control group(F=0.540,P=0.586).Conclusion:The acute stress encourages individuals to choose risky behavior patterns,but their behavior was regulated by major types.
