汉语高功能自闭症儿童句子理解策略及影响因素

Sentence Comprehension Strategies and Influencing Factorsin Mandarin-Speaking Children with High Functioning Autism

采用句图指认任务,考察了汉语高功能自闭症儿童和典型发展儿童匹配组的句子理解策略及影响因素。结果发现,在宾语无修饰语句中,两组儿童理解SVO句的正确率均显著大于把字句和被字句,说明两组儿童对把字句和被字句进行了句法移位;在简单修饰语句中,两组儿童都采用了语义策略来帮助完成句子理解,但是语义策略的使用情况受到句式结构的影响;而在理解复杂修饰语句时,汉语高功能自闭症儿童的正确率显著小于典型发展儿童,表明他们理解含复杂修饰语句存在损伤,可能与其言语工作记忆容量相关。

By using the mission of picture selection from a sentence,this study investigated the sentence comprehension strategies and influencing factors in Mandarin-speaking children with High Functioning Autism(HFA children)and matched typically developing children(TD children).The results showed that,in comprehension of non-modifiers?sentences,the correct rate of SVO sentences in both groups of children is significantly higher than that of ba(把)and bei(被)sentences.This shows that both groups of children use syntactic movement in comprehension of ba and bei sentences;In comprehension of simple-modifiers?sentences,both groups of children use semantic strategies which is influenced by the structure of sentences・While in comprehension of complex-modifiers?sentences,the correct rate of HFA children is significantly lower than TD children.This shows that HFA children have impairment in comprehension of complex modifiers?movement sentences,which may be related to their verbal working memory capacity.
