涉及风险的决策往往必须在压力大的情况下做出。对压力反应的行为和大脑差异的研究表明,压力可能对男性和女性的冒险行为产生不同的影响。在这项研究中,参与者在完成压力挑战或控制任务后15分钟玩了一个旨在衡量冒险行为的电脑游戏(气球冒险任务)。压力增加了男性的冒险行为,但减少了女性的冒险行为。急性压力放大了风险寻求的性别差异,使女性更回避风险,男性更寻求风险。进化原理可以解释这些压力引起的冒险行为的性别差异。
Decisions involving risk often must be made under stressful circumstances. Research on behavioral and brain differences in stress responses suggest that stress might have different effects on risk taking in males and females. In this study, participants played a computer game designed to measure risk taking (the Balloon Analogue Risk Task) fifteen minutes after completing a stress challenge or control task. Stress increased risk taking among men but decreased it among women. Acute stress amplifies sex differences in risk seeking; making women more risk avoidant and men more risk seeking. Evolutionary principles may explain these stress-induced sex differences in risk taking behavior.
