风险选择涉及不同的大脑网络模式. 避免做出错误的决定显示出强大的网络连贯性,而接近它们则显示出有限的沟通,为决策过程提供了洞察力.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 决策科学 决策科学 决策科学
背景情况:
- 个人经常在模两可的条件下做出决定,需要对选择进行审议,以使行动与目标保持一致.
- 冒险行为及其潜在的神经电路是积极研究的领域,经常使用爱荷华州博任务 (IGT) 来评估不确定的决策.
- 之前的研究已经确定了奖励和突出网络在决策中的参与,重点是对比有利与不利的选择.
研究的目的:
- 在功能磁共振成像 (fMRI) 过程中使用修改的爱荷华博任务 (IGT) 调查主动和被动"坏"决策期间的互联网连接.
- 确定方法和避免不利决策之间的可分离的连接模式.
- 探索这些神经模式和与行为方法风格相关的个性特征之间的关系.
主要方法:
- 功能磁共振成像 (fMRI) 对24名参与者进行了修改后的IGT.
- 使用网络集群分析来检查互联网连接.
- 评估了神经连接模式和人格特征之间的相关性.
主要成果:
- 避免"糟糕"的决策 (通过不利的甲板) 展示了一般的互联网网络连接.
- 接近"糟糕"的决策 (玩不利的甲板) 显示了轨道前皮层 (OFC) 与其他大脑区域的功能断开.
- 奖励响应能力的降低与侧面OFC和前额外区域 (aSMG) 之间功能连接的增加相关.
- 增加的驱动与背部前带带皮层 (dACC) 和前半岛 (aINS) 之间的功能连接相关.
结论:
- 接近和避免不利的决策是由不同的神经通信模式所支的.
- 避开决策的特点是整合和连贯的网络活动,而接近决策显示有限的互联网网络通信.
- 初步发现表明,人格特征与突出性和奖励评估网络中的神经通信之间存在联系.
