Ear Hear 2003;24:392–405. 1159/000078392 Received: February 6, 2003 Accepted after revision: April 4, 2004 Development of Language and Speech Perception in Congenitally, Profoundly Deaf Children as a Function of Age at Cochlear Implantation Mario A. , USA Key Words Cochlear implants W Congenitally deaf children W Language development, sensitive periods W Speech perception Abstract Like any other surgery requiring anesthesia, cochlear implantation in the first few years of life carries potential risks, which makes it important to assess the potential benefits.
Difficulties encountered by ‘wild’ children in learning language late in life may be due to deprivation of experiences that are unrelated to language, rather than to a sensitive period for language learning. The sign language data are compelling, but it is possible that sign languages are acquired in different ways than oral languages. Additionally, deaf children who were exposed to sign language late in life may have suffered social or cognitive consequences due to the lack of early input. Changes in perceptual or learning capacities may be due to changes in motivation or opportunity, rather than to a biological window that closes with age.
Until the advent of cochlear implants (CIs), however, there existed no satisfactory treatment for profound deafness. A CI is an electronic device, part of which is surgically implanted into the cochlea and the remaining part worn externally. The CI functions as a sensory aid, converting mechanical sound energy into a coded electric stimulus that bypasses damaged or missing hair cells of the cochlea and directly stimulates remaining auditory neural elements. , 1995]. However, CIs also provide children with critical auditory sensory input necessary for the development of speech and language production.
