概括

具有高度自闭症特征的个体表现出减少的情感灵活性,更多地与情感任务作斗争. 这项研究使用事件相关潜力 (ERP) 来揭示认知处理中的这些差异.

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:

情感灵活性对于情绪调节至关重要.
有限的研究存在于高自闭症特征的个体的情感灵活性.

研究的目的:

使用情感任务交换范式,研究高自闭症特征的个体的情感灵活性.
使用事件相关潜力 (ERP) 技术探索情感灵活性的神经基础.

主要方法:

使用一种情感任务切换范式,参与者识别了面部的性别和情感.
根据自闭症谱系系数 (AQ) 得分,参与者被分为高自闭症组 (HAG) 和低自闭症组 (LAG).
在任务交换过程中记录了与事件相关的潜力 (ERP).

主要成果:

在转换到情感任务时,HAG显示了更高的行为情感切换成本,并改变了N2和P3 ERP组件.
在HAG中观察到一种情感不对称的交换成本,与性别任务相比,情感任务的成本更高.
当地行动组表现出对称的转换成本,与HAG的模式不同.

结论:

具有高度自闭症特征的个体在情感灵活性方面遇到困难,特别是在情感处理任务中.
在HAG中观察到的情感不对称切换成本与之前在自闭症儿童和普通人群中发现的结果不同.
性别和情感处理之间的任务主导地位可能会随着自闭症特征的增加而发生变化,对情感任务的潜在下降.

Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
