概括
患有互联网成 (IA) 的人在生气时做出更延迟的奖励选择,与健康的对照人不同. 这表明愤怒影响IA决策,可能与前额叶皮质大脑活动有关.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 行为经济学是一种行为经济学.
背景情况:
- 时间间决策涉及到在立即的较小奖励和延迟的较大奖励之间做出选择.
- 情绪状态,特别是愤怒,显著影响这些选择,正如评估倾向框架 (ATF) 理论所建议的那样.
- 互联网成 (IA) 与改变的决策过程有关.
研究的目的:
- 研究愤怒如何影响IA患者的时间间决策.
- 利用功能近红外光谱学 (fNIRS) 探索这些效应背后的神经机制.
- 测试ATF理论对IA个体的适用性.
主要方法:
- 19名IA患者和20名健康对照 (HC) 参与了这项研究.
- 参与者在中性和愤怒情绪条件下完成了货币选择任务.
- fNIRS测量了前额叶皮质 (PFC) 中的血液动力学反应.
主要成果:
- 与HC相比,IA患者在轨道前皮层 (OFC) 和左背侧前皮层 (L-dlPFC) 中表现出更大的延迟折扣和减少的大脑激活.
- 与HC不同的是,IA患者在经历愤怒时做出了更大的奖励选择,而非更大的奖励选择.
- 与中性条件相比,IA患者的L-dlPFC中的大脑激活在愤怒下增加.
结论:
- 在IA中时间间决策受损可能源于OFC和L-dlPFC功能障碍.
- 愤怒似乎影响IA个体的时间间选择,支持ATF理论.
- 在AI中,L-dlPFC可能在愤怒如何影响时间间决策方面发挥关键作用.

01:37Reason and Intuition
6.4K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
