We use skin conductance to measure emotional arousal in subjects who make risky choices under time pressure or time delay. Our results show a strong correlation between subjects’ skin conductance responses and their risky choices under time pressure but not under time delay. Subjects were more risk taking for higher levels of measured electrodermal activity (skin conductance). In line with descriptive theories of risky choice, the effect was most pronounced for choices involving losses rather than gains. Taken together, our findings indicate that participants under time pressure rely on affect at the point of decision-making. This provides support for behavioral models that recognize the role of emotional brain systems in decision-making under risk.

情感反应预示着快速而不是缓慢决策的风险选择。

我们使用皮肤电导来衡量在时间压力或时间延迟下做出冒险选择的受试者的情绪唤醒。我们的结果表明，受试者的皮肤电导反应与其在时间压力下而不是在时间延迟下的风险选择之间存在很强的相关性。受试者承担更高水平的测量皮肤电活动（皮肤电导）的风险。与风险选择的描述性理论一致，这种影响对于涉及损失而不是收益的选择最为明显。综上所述，我们的研究结果表明，处于时间压力下的参与者依赖于决策时的影响。这为识别情绪大脑系统在风险决策中的作用的行为模型提供了支持。
