Previous research has shown that emotion can significantly impact decision-making in humans. The current study examined whether or not and how situationally induced emotion influences people to make inter-temporal choices.
Affective pictures were used as experiment stimuli to provoke emotion, immediately followed by subjects' performance of a delay-discounting task to measure impulsivity during functional magnetic resonance imaging.
Results demonstrate a subsequent process of increased impulsive decision-making following a prior exposure to both high positive and negative arousal stimuli, compared to the experiment subjects' experiences with neutral stimuli. Findings indicate that increased impulsive decision-making behaviors can occur with high arousal and can be characterized by decreased activities in the cognitive control regions such as prefronto-parietal regions.
These results suggest that 'stabilization of high emotional arousal' may facilitate a reduction of impulsive decision-making and implementation of longer term goals.
先前的研究表明，情绪会显著影响人类的决策。当前的研究考察了情境诱发的情绪是否以及如何影响人们做出跨期选择。
使用情感图片作为实验刺激来激发情绪，紧接着让受试者在功能磁共振成像期间执行延迟折扣任务以测量冲动性。
结果表明，与接触中性刺激的实验对象的经历相比，在先前接触高正性和高负性唤醒刺激之后，会出现冲动决策增加的后续过程。研究结果表明，高唤醒会导致冲动决策行为增加，其特征可能是前额顶叶等认知控制区域的活动减少。
这些结果表明，“高情绪唤醒的稳定”可能有助于减少冲动决策并促进长期目标的实现。
