TY - JOUR T1 - Comparing expressive grammar in children with autism and typically developing children TT - JF - SABA-JMS JO - SABA-JMS VL - 2 IS - 2 UR - http://journalsystem.ir/article-1-66-en.html Y1 - 2016 SP - 81 EP - 88 KW - Autism KW - Persian KW - Language grammar KW - Expression N2 - Language impairment is one of the main characteristics of children with autism; however, findings of the language deficits in these children have been inconclusive, and even less is known about the language profiles of Persian children with autism. Due to the heterogeneity in autism, we also need extensive investigations on the properties of their language in different languages. The aim of this study was to evaluate grammatical characteristics in children with autism and reveal the differences between with age-matched and language-matched normal children. Research data were collected at 10 autistic (ages 6 to 9) and 20 normal children (10 age-matched and 10 language-matched). First we used The GARS-2, and the ASSQ for diagnosing high-functional Autistic children. Then expression of syntactic structures in autistic and normal Children was assessed by using a measure of children’s expressive grammar. And finally data analyzed with mann-whitney test. The result showed that there is significant difference between autistic group and age-matched group in all structure except in WH question, yes/no question, different type of relative clauses, tense, aspect, mood, different type of pronouns and preposition. But comparison between autistic group and language-matched group showed that there is no significant difference in most structures except WH question, yes/no question, complementary relative clauses, different type of pronouns and preposition. Overall, autistic children demonstrated consistent expressive impairment in questions, relative clause and pronouns that should be noted that should be seriously considered in identification and treatment.
