概括

这项研究揭示了在奖励处理过程中寻求风险的与不愿冒险的个体中独特的神经活动模式. 与事件相关的潜力 (ERP),如刺激前的消极性 (SPN) 和反相关的消极性 (FRN),突出了这些差异.

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:

风险偏好的个体差异与奖励处理变化有关.
在寻求风险和避免风险的个体中,这些差异背后的神经机制尚不清楚.

研究的目的:

调查和比较在寻求风险和不愿冒风险的个体中不同阶段的奖励处理的电生理学相关性.
识别神经标记,区分寻求风险和不愿冒风险的行为.

主要方法:

参与者根据气球模拟风险任务 (BART) 被分为寻求风险或避免风险的参与者.
在博任务期间记录了脑电图 (EEG) 和事件相关潜能 (ERP).
分析重点是预期期间的刺激前的消极性 (SPN) 和结果评估期间的反相关的消极性 (FRN).

主要成果:

寻求风险的人主要选择高风险的选择,而避风险的人更喜欢低风险的选择.
寻求风险的人显示,低风险选项的SPN减弱,损失的FRN增加.
避免风险的人没有根据风险水平或结果显示SPN或FRN的显著差异.

结论:

与事件相关的潜力 (ERP) 在寻求风险和避免风险的个体中有效区分奖励处理.
与动机和认知控制相关的神经过程对于解释基于奖励的决策变化至关重要.

Motivational Bias

Motivational Bias

Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
