Phonological working memory and its relationship with language abilities in children with cochlear implants


Background and Aim: Many studies have demonstrated a close relationship between phonological working memory and language abilities in normal children and children with language developmental disorders, such as those with cochlear implants. A review of these studies would clarify communication and learning in such children and provide more comprehensive information regarding their education and treatment. In this study, the characteristics of phonological working memory and its relationship with language abilities in children with cochlear implants was examined.
Recent Findings: In this study, the authors studied the characteristics of phonological working memory and its relationship with language abilities of children with cochlear implants. These studies showed that in addition to demographic variables, phonological working memory is a factor that affects language development in children with cochlear implants. Children with cochlear implants typically have a shorter memory span.
Conclusion: It is thought that the deficiency in primary auditory sensory input and language stimulation caused by difficulties in the processing and rehearsal of auditory information in phonological working memory is the main cause of the short memory span in such children. Conversely, phonological working memory problems may have adverse effects on the language abilities in such children. Therefore, to provide comprehensive and appropriate treatment for children with cochlear implants, the reciprocal relationship between language abilities and phonological working memory should be considered.
