Training to improve language outcomes in cochlear implant recipients

Abstract

Cochlear implants (CI) have brought with them hearing ability for many prelingually deafened children. Advances in CI technology have brought not only hearing ability but speech perception to these same children. Concurrent with the development of speech perception has come spoken language development, and one goal now is that prelingually deafened CI recipient children will develop spoken language capabilities on par with those of normal hearing (NH) children. This goal has not been met purely on the basis of the technology, and many CI recipient children lag behind their NH peers with large variability in outcomes, requiring further behavioral intervention. It is likely that CI recipient children struggle to develop spoken language at NH-like levels because they have deficits in both auditory and cognitive skills that underlie the development of language. Fortunately, both the auditory and cognitive training literature indicate an improvement of auditory and cognitive functioning following training. It therefore stands to reason that if training improves the auditory and cognitive skills that support language learning, language development itself should also improve. In the present manuscript we will review the auditory and cognitive training and their potential impact on speech outcomes with an emphasis on the speech perception literature.
