Title: Benefits of simultaneous bilateral cochlear implantation on verbal reasoning skills in prelingually deaf children. Author: Jacobs E, Langereis MC, Frijns JH, Free RH, Goedegebure A, Smits C, Stokroos RJ, Ariens-Meijer SA, Mylanus EA, Vermeulen AM. Journal: Res Dev Disabil; 2016 Nov; 58():104-13. PubMed ID: 27608372. Abstract: BACKGROUND: Impaired auditory speech perception abilities in deaf children with hearing aids compromised their verbal intelligence enormously. The availability of unilateral cochlear implantation (CI) auditory speech perception and spoken vocabulary enabled them to reach near ageappropriate levels. This holds especially for children in spoken language environments. However, speech perception in complex listening situations and the acquisition of complex verbal skills remains difficult. Bilateral CI was expected to enhance the acquisition of verbal intelligence by improved understanding of speech in noise. METHODS: This study examined the effect of bilateral CI on verbal intelligence of 49 deaf children (3;5-8;0 years). Relations between speech perception in noise, auditory short-term memory and verbal intelligence were analysed with multiple linear regressions. In addition, the interaction of educational setting, mainstream or special, on these relations was analysed. RESULTS: Children with bilateral CI obtained higher scores on verbal intelligence. Significant associations were present between speech perception in noise, auditory short-term memory and verbal intelligence. CONCLUSION: Children with simultaneous bilateral CIs showed better speech perception in noise than children with unilateral CIs, which mediated by the auditory short-term memory capacity, enhanced the ability to acquire more complex verbal skills for BICI children in mainstream education.[Abstract] [Full Text] [Related] [New Search]
