概括

患有高特征焦虑症 (HTA) 的人在预测情绪时表现出大脑连接的改变. 尽管他们预计对积极事件的兴奋程度较低,但他们的情感价值预测仍然完好无损,这表明了补偿的神经努力.

科学领域:

神经科学是一个神经科学.
心理学心理学心理学
认知科学认知科学

背景情况:

高特征焦虑与负面的情绪预测偏见有关.
这种偏差的潜在神经机制尚未得到充分理解.

研究的目的:

调查与高特征焦虑 (HTA) 与低特征焦虑 (LTA) 相关的神经机制与高特征焦虑 (HTA) 个体的情绪预测.

主要方法:

招募了38名HTA和38名LTA参与者.
使用了社会情感预测任务和休息状态fMRI.
分析了大脑区域之间的功能连接.

主要成果:

与LTA相比,HTA组预计未来积极事件的兴奋程度较低,但与LTA相比具有相似的价值.
HTA集团显示,对未来负面事件的预测是完整的.
HTA组表现出左侧vmPFC和舌环之间以及背部前部岛屿和后部带带皮层之间的功能连接性增加.

结论:

在HTA个体中功能连接的改变可能反映了在情绪预测中神经力的增加.
尽管改变了兴奋预期,但价值预测仍然完好无损,可能是由于补偿机制.

Traits and States

Traits and States

Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations. For example, extraversion, a well-known trait, manifests in individuals as talkative, energetic, and enthusiastic behaviors. These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits,...

Subjective well-being (SWB) refers to an individual's self-evaluation of their overall life satisfaction, happiness, and fulfillment. This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being.
