[Sentence writing and perception of written sentences in hearing-impaired and normal-hearing primary school students in Hamadan, western Iran]

ABSTRACT

Learning language is acquired in early childhood and gradually developed by new words and new structures. Hearing sense is the most important acquisition for learning this skill. Hearing disorders are barriers for natural language learning. The purpose of this study was to investigate the relationship between writing sentences and perception of written sentences in hearing-impaired and normal-hearing students. A cross- sectional study was conducted among thirty hearing-impaired students with hearing loss of 70-90 dB and thirty normal hearing students. They were selected from 3[rd] grade primary school students in Hamadan, a large city in Western Iran. The language skills and non language information was assessed by questionnaire, Action Picture Test, and Sentence Perception Test. Results showed that there was a significant relation between writing sentences and perception of written sentences in hearing impaired students [p<0.001], [r=0.8]. this significant relation was seen in normal-hearing students as well [p<0.001], [r=0.7]. Disability of hearing-impaired students in verbal communication is not only related to articulation and voice disorders but also is related to their disability to explore and use of language rules. They suffer lack of perception of written sentences, and they are not skilled to convey their feeling and thoughts in order to presenting themselves by using language structures
