自闭症谱系障碍(autism spectrum disorder, ASD,简称自闭症)是一种神经发育障碍,通过脑电活动研究可以对自闭症儿童脑功能发展进行客观评价.在个体社会发展中情绪认知能力十分重要,自闭症儿童的情绪认知缺陷对其社会互动能力造成了极大的影响,阻碍了自闭症儿童的社会性发展.本研究主要通过分析情绪视频诱发被试儿童产生正面与负面情绪过程中的额叶、颞叶、枕叶等脑区的脑电活动,并结合情绪性能指标和认知水平,探索自闭症儿童和典型发展儿童的各自表现以及其脑电差异性.实验共招募80名儿童(自闭症儿童组: 40名;典型发展儿童组: 40名),通过快速傅里叶变换方法对被试儿童脑电分脑区进行功率谱分析...

Autism spectrum disorder (ASD, hereafter autism) is a neurodevelopmental disorder. The symptoms of autism, including the core features of social interaction and language communication disorders, repetitive stereotyped behaviors, and limited narrow interest, are most obvious in children 2-3 years old. Research also shows that childhood is the most critical period for autism diagnosis and behavioral intervention. Because emotional recognition ability is of great importance to individual social development, the emotional recognition defect of chil...
