孤独症谱系障碍儿童社会定向异常特征的研究进展

Advances in abnormal characteristics of social orienting in children with autism spectrum disorder

社会动机理论是解释孤独症谱系障碍(autism spectrum disorder,ASD)成因的理论,该理论认为ASD儿童的社会动机缺陷是他们产生ASD症状的主要原因。ASD儿童的社会定向异常主要表现在社会偏好异常、共同注意异常与面孔加工策略异常3个方面。ASD儿童可能存在颞枕部的N170、额中央部的P400成分异常及杏仁核功能障碍。未来ASD儿童社会定向的研究应进一步扩大实验的生态效度,深化理论模型并加强纵向研究,结合多种相关技术以拓宽研究领域。

The social motivation theory is a theory to explain the causes of autism spectrum disorder(ASD).It believes that the social motivation deficiency existing in children with ASD is the main reason for their symptoms.The abnormal social orienting of children with ASD is mainly manifested in three aspects:abnormal social preference,abnormal co-attention,and abnormal face processing strategy.There may be some impairment in the N 170 and P 400 components and amygdala function in children with ASD.In the future,the research on the social orienting of children with ASD should further expand the ecological validity of the experiment,deepen the theoretical model,strengthen longitudinal research,combine a variety of related technologies,and broaden the research field.
