A Study On The Recognition Of Tongue Different Words In Chinese Autistic Children

In this study,through lexical and sentence levels, we studied the homograph recognition ability of Chinese children with autism.The study analyze their semantic priming effect and the ability of integrating the sentence context.Then probed their reading trait and the way of lexical semantic representation which different from typically developing children.16 children with autism and 16 typically developing children were matched according to physiological age, verbal IQ, performance IQ, total IQ, vocabulary recognition capability, and literacy standards.Through homograph recognition tasks in lexical and sentence levels,the study compared the naming latency and correct rate of the two groups in the tasks.Then conduct a exhaustive study of the homograph recognition ability of the two groups.Chinese children with autism were faster to name target words preceded by semantically related primes than target words preceded by unrelated primes.Their correct rate were equal to typically developing children in two homograph recognition tasks.And the recognition ability in sentence context were better than in lexical condition.Then we made the conclusion that Chinese children with autism showed significant semantic effect.They can exactly reading the homograph with the prompt context.The result stand against those obtained by previous studies that have found that,when homographs are the target,individuals with autism do not take account of context to disambiguate target words because of their weak central coherence.Their better performance in sentence also against the suspect that children with autism can’t process context because of the working memory load.When discern the homograph,children with autism are effected by the frequency of the homograph in the sentence context task but not in the lexical condition task. This is due to sentence provides greater context, they have the ability to process context, and then subject to daily reading experience and vocabulary occurrence frequency.On the other hand is their lexical semantic representation style is different from typically developing children.Their conscious of extract the meaning of a single word from the sentence is not strong, so they don’t have the stable meaning-lexical representation. When using the meaning prime the target word,they read them randomly,and not affected by the frequency of the vocabulary.Overall,the ability of Chinese children with autism to discern the homograph is equal to typically developing children, they don’t have the absolute damage.
