概括
患有自闭症的儿童对自己的名字的脑反应与典型发育的儿童相似,尽管在日常生活中有所不同. 年龄影响了大脑的大脑.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 自闭症谱系障碍研究研究
背景情况:
- 对自己的名字反应减弱是早期自闭症预测因素.
- 自闭症中自名反应的神经相关性研究不足.
- 了解这些神经反应对于早期识别和干预至关重要.
研究的目的:
- 在有自闭症和没有自闭症的学龄儿童中调查听到自己的名字时的神经反应.
- 为了比较自闭症和神经类型儿童之间的自我特异性神经效应.
- 探索年龄对儿童自身名称处理的影响.
主要方法:
- 使用脑电图 (EEG) 来记录34名自闭症儿童和33名对照儿童 (7-13岁) 的大脑活动.
- 作为听觉刺激,向参与者展示了自己的名字,一个亲密的另一个人的名字和一个未知的另一个人的名字.
- 采用一种听觉奇怪的范式来分析神经反应,专注于P3,N1和SON消极成分.
主要成果:
- 在这两组中,与亲密对方的名字相比,对自己的名字增强了状P3振幅.
- 较年长的孩子比较年轻的孩子表现出更强的自我特异性P3效应.
- 在患有自闭症和没有自闭症的儿童之间没有发现自我特异性P3效应的显著差异,这与父母的报告相矛盾.
结论:
- 体P3组件,而不是N1或SON负面性,在学龄儿童中显示了对自己的名字的自我特异性增强.
- 年龄调节P3振幅的自称效应,可能解释小组差异.
- 需要进一步的研究来协调神经和行为发现,在不同年龄段的自闭症中处理自己的名字.

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

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.
