Abstract: (1144 Views)
Objectives: Since the auditory system is the basis for language acquisition, the presence of phonological deficits is expected in people with hearing impairment. The aim of this study was to compare the phonological measurement indices in children with cochlear implants, hearing aids, and normal-hearing children.
Methods: The participants were 100 Persian-speaking children aged 3 to 6 years including 25 children the severe hearing loss with bilateral hearing aids, 25 children with unilateral cochlear implants, and 50 children with normal hearing participated in this cross-sectional study. Children with hearing aids and children with cochlear implants were selected by convenience sampling from the Naghma and Parvaneha Rehabilitation Center for hearing-impaired children in Mashhad. The phonological subtest of the Persian version of the Diagnostic Evaluation of Articulation and Phonology (DEAP) which includes the two tasks of the picture naming and the picture description was performed, and the phonological indices including Phonological mean length of utterance, Phonological whole- word proximity, Proportion of Whole-Word Correctness, Percentage of Consonants Correct, and Percentage of Vowel Correct were calculated. The performances of participants in the three groups in each index were compared in the task of picture naming and description. Also, the performance of the participants in the two tasks was compared in each group
Results: There was a significant difference in the mean scores of all phonological indices among the three groups (P<0.001), so that, children with normal hearing performed better than cochlear-implanted and hearing-impaired children, and cochlear-implanted children also had better performance compared to hearing children. Also, the difference in the mean of all phonological indices in the two tasks was only significant in the group with hearing aids (P<0.05).
Conclusion: Children with cochlear implants despite having a new and more useful technology than hearing aids, still have problems with phonemic accuracy, especially in whole-word indices, compared to normal children. Also, the difference in indicators between the two tasks in the group with hearing aids confirms the influence of the phonetic context, which should be taken into account in the evaluation and treatment of phonological deficits in these children.
