Most children with hearing loss who receive cochlear implants (CI) learn spoken language, and parents must choose early on whether to use sign language accompany speech at home. We address parents' of before after CI positively influences auditory-only recognition, intelligibility, reading outcomes.Three groups CIs from a nationwide database differed in the duration exposure provided their homes were compared progress through elementary grades. The did not differ demographic, auditory, or...
Adult listeners are able to recognize speech even under conditions of severe spectral degradation. To assess the developmental time course this robust pattern recognition, recognition was measured in two groups children (5–7 and 10–12 years age) as a function degree resolution. Results were compared performance adults listening same materials conditions. The detail systematically manipulated using noise-band vocoder which filtered noise bands modulated by amplitude envelope from speech....
Abstract The development of language and communication may play an important role in the emergence behavioral problems young children, but they are rarely included predictive models development. In this study, cross-sectional relationships between language, attention, behavior were examined using parent report, videotaped observations, performance measures a sample 116 severely profoundly deaf 69 normally hearing children ages 1.5 to 5 years. Secondary analyses performed on data collected as...
The principal goal of this study was to investigate the relationships between maternal contributions (e.g., involvement, self-efficacy, linguistic input) and receptive expressive (oral sign) language skills in young children with cochlear implants.Relationships children's were investigated by using correlation regression analyses. Thirty-two mothers (mean age = 36.0 yr) their 4.8 videotaped during free play storybook interactions. Mothers' quantitative (MLU, number word-types) mothers'...
This study examined specific spoken language abilities of 160 children with severe-to-profound sensorineural hearing loss followed prospectively 4, 5, or 6 years after cochlear implantation.Ninety-eight received implants before 2.5 years, and 62 between 5 age.Language was assessed using four subtests the Comprehensive Assessment Spoken Language (CASL). Standard scores were evaluated by contrasting age implantation follow-up test time.Children implanted under achieved higher standard than...
To determine whether preschool-age children with cochlear implants have age-appropriate phonological awareness and print knowledge to examine the relationships of these skills related speech language abilities.The sample comprised 24 (CIs) 23 peers normal hearing (NH), ages 36 60 months. Children's knowledge, awareness, language, production, perception abilities were assessed.For CI group's mean score fell within one standard deviation Test Preschool Early Literacy's (Lonigan, Wagner,...
The goal of this study was to longitudinally examine relationships between early factors (child and mother) that may influence children's phonological awareness reading skills 3 years later in a group young children with cochlear implants (N = 16). Mothers were videotaped during two storybook interactions, oral language assessed using the "Reynell Developmental Language Scales, third edition." Three later, awareness, skills, "Phonological Awareness Test," "Woodcock–Johnson-III Diagnostic...
Purpose To examine the validity of MacArthur–Bates Communicative Development Inventories (CDI) for measuring language abilities in children with profound hearing loss who are using cochlear implants. Method Twenty-four implants and their mothers participated this study. Children ranged age from 32 months to 86 (the majority were 66 old). The number postimplantation 3 60 around 24 months). Mothers completed CDI before behavioral testing. Behavioral measures included Reynell Developmental...
The Childhood Development after Cochlear Implantation (CDaCI) study is a longitudinal multicenter investigation designed to identify factors influencing spoken language in young deaf children with cochlear implants. Normal-hearing peers serve as controls. As part of comprehensive evaluation battery, speech recognition hierarchy was assess how well these recognize stimuli across developmental stages. Data were analyzed for the earliest measures 42 pairs reaching 1 year follow-up. A number...
Children with severe to profound sensorineural hearing loss face communication challenges that influence language, psychosocial and scholastic performance. Clinical studies over the past 20 years have supported wider application of cochlear implants in children. The Childhood Development after Cochlear Implantation (CDaCI) study is first longitudinal multicentre, national cohort evaluate systematically early implant (CI) outcomes objective was compare children who undergone implantation,...
Parent and child joint book reading (JBR) characteristics parent facilitative language techniques (FLTs) were investigated in two groups of parents their young children; children with normal hearing (NH; n = 60) loss (HL; 45). Parent-child dyads videotaped during JBR interactions, behaviors coded for specific using a scale developed this study. Children's oral skills assessed the Preschool Language Scale-4 (PLS-4). Parents HL scored higher on four subscales JBR: Literacy Strategies Teacher...
The effect of amplitude-modulated (AM) noise on speech recognition in listeners with normal and impaired hearing was investigated two experiments. In the first experiment nonsense syllables were presented high-pass steady-state or AM to determine whether release from masking relative significantly different between normal-hearing hearing-impaired subjects when groups listened under equivalent masker conditions. tested experimental conditions: (a) a spectrally shaped broadband that produced...
Background: Newborn Hearing Screening (NHS) programs aim to reduce the age of identification and intervention infants with hearing loss. It is generally accepted that NHS achieve outcome, but few studies have compared children who were screened those not in same study during time period. This takes advantage emerging screening California compare based on status at milestones. Purpose: The purpose this was outcomes cohorts loss, some for loss birth others screened. Specifically, measures are...
Objective: To develop a speech recognition index that summarizes data collected through an array of age-appropriate hierarchical tests in longitudinal study. Study Design: Prospective cohort. Setting: Six tertiary referral centers the Childhood Development after Cochlear Implantation (CDaCI) Study. Patients: One hundred eighty-eight children implanted at age 5 years or younger and 97 age-comparable normal-hearing controls. Intervention: implantation. Main Outcome Measures: measures were...
Growing evidence supports the notion that dynamic gene expression, subject to epigenetic control, organizes multiple influences enable a child learn listen and talk. Here, we review neurobiological genetic on spoken language development in context of results longitudinal trial cochlear implantation young children with severe profound sensorineural hearing loss Childhood Development after Cochlear Implantation study. We specifically examine participants who were congenitally deaf (N = 116)....
Cochlear implantation (CI) has become the mainstay of treatment for children with severe-to-profound sensorineural hearing loss (SNHL). Yet, despite mounting evidence clinical benefits early implantation, little data are available on long-term societal and comparative effectiveness this procedure across various ages implantation-a choice parameter parents clinicians high prognostic value outcome. As such, aim present study is to evaluate a model consequences timing intervention from economic...
Objectives: A postlingually implanted adult typically develops hearing with an intact auditory system, followed by periods of deafness (or near deafness) and adaptation to the implant. For early child whose brain is highly plastic, system matures consistent input from a cochlear It likely that implant users fundamentally different than adults. The purpose this study compare basic psychophysical capabilities limitations these two populations on spectral resolution task determine potential...
In Brief Objective The purpose of this study was to investigate the combined lexical effects word frequency and neighborhood density (acoustic-phonetic similarity) on recognition words spoken in isolation sentences for children with normal hearing cochlear implants. Design Lexically controlled were created from a subset obtained vocabulary between ages 3 5 yr. Two sentence lists generated, applying definitions procedures Kirk, Pisoni, Osberger (1995) accordance Neighborhood Activation Model...
