本研究考察了社会应激（特里尔社会应激测试）对24名男性和32名女性大学生的情感和生理反应以及他们随后在决策任务（爱荷华州赌博任务）中的表现的影响。56名参与者被随机分配到社会压力源或控制条件。与对照组相比，压力条件下的参与者心率和皮肤电导反应更高，报告了更多的负面影响，并且在决策任务中做出了不太有利的选择。探索性回归分析显示，在男性中，较高的心率水平与爱荷华州赌博任务中的风险选择呈正相关，而对于女性，这种关系是曲线的。探索性相关分析表明，在压力条件下，较低水平的皮肤电导与较高水平的物质使用和赌博有关。结果表明，压力源的存在通常可能导致未能参加决策的全部可能后果。男性和女性的压力反应程度与成功决策之间的关系模式可能不同。
The study examined the effects of a social stressor (Trier Social Stress Test) on 24 male and 32 female college students’ affective and physiological reactivity and their subsequent performance on a decision-making task (Iowa Gambling Task). The 56 participants were randomly assigned to a social stressor or a control condition. Compared to controls, participants in the stress condition responded with higher heart rates and skin conductance responses, reported more negative affect, and on the decision-making task made less advantageous choices. An exploratory regression analysis revealed that among men higher levels of heart rate were positively correlated with riskier choices on the Iowa Gambling Task, whereas for women this relationship was curvilinear. Exploratory correlational analyses showed that lower levels of skin conductance within the stress condition were associated with greater levels of substance use and gambling. The results suggest that the presence of a stressor may generally result in failure to attend to the full range of possible consequences of a decision. The relationship pattern between the degree of stress responding and successful decision making may be different for men and women.
