Although cochlear implants improve the ability of profoundly deaf children to understand speech, critics claim that the published literature does not document even a single case of a child who has developed a linguistic system based on input from an implant. Thus, it is of clinical and scientific importance to determine whether cochlear implants facilitate(More)
The Meaningful Auditory Integration Scale (MAIS) was developed to evaluate meaningful use of sound in everyday situations by profoundly hearing-impaired children. Information about the use of sound in everyday situations is obtained with a parent interview technique. Initial findings obtained with this scale are reported in Experiment 1 for children who use(More)
Elevated plasma levels of low density cholesterol and their major apolipoprotein (apo B) are associated with an increased risk of coronary artery disease (CAD). We have examined allele frequencies of restriction fragment length polymorphisms (RFLP) of the apo B gene in 111 male Caucasians with premature CAD (mean age 49 +/- 7 years) and in 122 elderly(More)
OBJECTIVE The development of oral language in children with a cochlear implant is dependent on numerous factors. Although baseline achievements have been established, ceiling attainment levels have yet to be explored. One indicator of a higher capability level is the ability of children with implants to learn to communicate orally using a second language.(More)
This study examined the development of language skills in 23 prelingually, profoundly deaf children following implantation with the CLARION Multi-Strategy Cochlear Implant. Language skills were assessed with the Reynell Developmental Language Scales (RDLS) preoperatively with hearing aids, and compared to postoperative performance after 6 months of Clarion(More)
The speech perception abilities of 19 children with onset of deafness before age 3 years was examined after they received the Nucleus multichannel cochlear implant. The children were divided into two groups based on age at onset of deafness: children with congenital deafness (n = 8) and children with onset of deafness after birth but before age 3 (n = 11).(More)
Expressive language skills were assessed in two groups of prelingually-deafened children using the Reynell Developmental Language Scales (RDLS). Results from a group of 89 unimplanted subjects provided cross-sectional data which suggested that profoundly deaf children without implants, on average, could only be expected to make 5 months of expressive(More)
The purpose of this experiment was first, to compare the performance of three matched groups of experimental subjects who used either a single-channel cochlear implant, a multichannel cochlear implant, or a two-channel vibrotactile aid on a battery of speech perception measures, and second, to compare the performance of subjects with residual hearing who(More)
The acquisition of speech perception and speech production skills emerges over a protracted time course in congenitally deaf children with multichannel cochlear implants (CI). Only through comprehensive, longitudinal studies can the full impact of cochlear implantation be assessed. In this study, the performance of CI users was examined longitudinally on a(More)
