概括

自闭症谱系障碍 (ASD) 的面部识别与神经类型个体相比,面部反转的影响较小. 这表明ASD患者在面部处理系统上的专业化减少了.

科学领域:

神经科学是一个神经科学.
认知科学认知科学
发展心理学发展心理学

背景情况:

面部处理对社会认知至关重要,并且在自闭症谱系障碍 (ASD) 中通常不典型.
面部反转效应是面部处理专业化的衡量标准,它揭示了大脑如何处理直立面与倒立面的情况.
了解ASD中面部处理的差异可以揭示自闭症中大脑的功能.

研究的目的:

包含的研究报告了基于表现的面部识别措施,用于自闭症和神经类型样本中的直立和倒置面部.
随机效应的多层模型框架被用于定量合成,遵守PRISMA指南.

主要成果:

分析包括来自38项研究 (1,764名参与者) 的122个效果大小.
与神经类型个体相比,自闭症个体表现出较少的面部反转效应 (g = -0.41).
这种效应在情绪识别任务和使用行为测量与电生理测量时更为明显.

结论:

平均而言,自闭症患者的面部识别受到面部反转的影响较小.
研究结果表明,自闭症患者的面部处理系统较少专业化,特别是通过行为方法识别情绪.

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.

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
