The comparative study of comprehension and expression of passive verbs in children with hearing loss with cochlear implant and normal children

Hearing loss affected all aspects of life, specially communication and language skills. Hearing loss in pre- lingual age has different impact on comprehension, speech, language and their performance. The purpose of this article is to compare comprehension skills and using passive verbs between children with hearing loss who use cochlear implant and their intact peers. In this study comprehension and using passive verbs have been compared between two groups of age and gender-matched children (10 in each group). Evaluation of passive verb's comprehension have been performed with test of passive verb's comprehension which normalized by Azar Mehri 1388. This test has 15 triplet pictures. The passive sentence related to each picture has been expressed conversationally and the child had to present it. If he/she could not distinguish the verb, the examiner had to reveal it. The test has 17 serialized pictures, in this method therapist explained each verb's serialized picture in the story telling way and a child completed the sentence also the therapist asked questions to guide a child toward the correct verb. There was a significant difference between normal and children with hearing loss in terms of the rate of comprehension and using passive verbs (comprehension p=0/008, usage p=0/008). The results show the significant delay in comprehension and using passive verbs, which may be due to a delay in diagnosis of the hearing loss, delay in receiving rehabilitation trainings, loss of lingual age and inefficient cochlear implant devices.
