Objectives: Specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. This study compared the passive comprehension as one of Syntactic Structures in Persian-speaking typically developing children and Specific language impaired children.
Methods: 10 children with Specific language impairment, 10 typically developing children matched for age with Specific language impaired children, and 15 younger typically developing children responded to passive sentence comprehension using picture identification task.
Results: The results of study revealed significant differences in comprehension of passive sentences in Specific language impaired children and age-matched typically developing children. The difference in Comprehension of passive sentences was not statistically significant in Children with Specific Language Impairment and younger typically developing children. There were significant differences in the comprehension of passive sentences between two typically developing children groups.
Discussion: While age-matched typically developing children comprehend passive structure completely, it seems that Specific language impaired children and younger typically developing children still have not come to a full comprehension of the passive structure. Specific language impaired children compared with age-matched and younger typically developing children interpreted passive sentences mostly as active sentences.

Keywords: specific language impairment, passive sentence, comprehension, language development Submitted: 10 August 2015 Accepted: 7 September 2015 Introduction A typically developed child is able to accomplish the basics of language development and comprehend and produce relatively complex sentences by the age of 4 to 5 years (1).
Van der Lely and Harris (16) tested 4 to 7-year-old children’s comprehension of syntactic structures such as active and passive voices constructions.
The first was passive sentences comprehension scores were significantly different in SLI children and TD-A children.
Children 50 to 57 months, in addition to selecting the picture representing active interpretation of the sentence, chose distracter pictures as well, which probably indicates that children 50 to 75 months still do not have a full comprehension of the passive structure.
The results of this study indicated that Persian speaking typically developing children aged 58 to 71 (TD-A) have had fairly complete comprehension of the passive structure.
