Purpose: General language abilities of children with cochlear implants have been thoroughly investigated, especially at young ages, but far less is known about how well they process language in real-world settings, especially in higher grades. This study addressed this gap in knowledge by examining recognition of sentences with complex syntactic…

Purpose: Child phonologists have long been interested in how tightly speech input constrains the speech production capacities of young children, and the question acquires clinical significance when children with hearing loss are considered. Children with sensorineural hearing loss often show differences in the spectral and temporal structures of…

Purpose: Common wisdom suggests that listening in noise poses disproportionately greater difficulty for listeners with cochlear implants (CIs) than for peers with normal hearing (NH). The purpose of this study was to examine phonological, language, and cognitive skills that might help explain speech-in-noise abilities for children with CIs.…

Purpose: Several acoustic cues specify any single phonemic contrast. Nonetheless, adult, native speakers of a language share weighting strategies, showing preferential attention to some properties over others. Cochlear implant (CI) signal processing disrupts the salience of some cues: In general, amplitude structure remains readily available, but…

Purpose: This study examined the potential roles of phonological sensitivity and processing speed in age-related declines of verbal working memory. Method: Twenty younger and 25 older adults with age-normal hearing participated. Two measures of verbal working memory were collected: digit span and serial recall of words. Processing speed was…

Much of speech perception research has focused on brief spectro-temporal properties in the signal, but some studies have shown that adults can recover linguistic form when those properties are absent. In this experiment, 7-year-old English-speaking children demonstrated adultlike abilities to understand speech when only sine waves (SWs)…

Purpose: It has been reported that children and adults weight differently the various acoustic properties of the speech signal that support phonetic decisions. This finding is generally attributed to the fact that the amount of weight assigned to various acoustic properties by adults varies across languages, and that children have not yet…

This study (with 16 children and 11 adults) examined an alternative to the Developmental Weighting Shift model which explains age-related differences in labeling of speech stimuli as due to increasing experience with word-internal structure. Findings rejected the alternative model, that changes in perceptual weighting strategies are due to…

This study tested the hypothesis that there is a developmental shift in the perceptual weighting of acoustic parameters that results from experience with a native language. Comparison of 17 3-year olds and 16 adults found that age-related differences in auditory sensitivity did not fully account for age-related differences in perceptual weighting…

Children (N=110, ages 8 to 10) with either normal or poor reading ability were tested on (1) ability to recall sequences of nonspeech tones presented at various rates, and (2) ability to make phonetic decisions using brief and transitional properties of the speech signal. Results did not support the hypothesis that temporal-processing deficits…

Seventeen children (ages 8-10) with hearing loss were tested on four types of tasks (speech perception, phonetic awareness, recall of word strings, and comprehension of sentences with complex syntax) and results were compared to controls. Subjects showed evidence of restricted access to acoustic information in the speech signal. (Contains…

This article reviews experiments that have revealed developmental changes in speech perception that accompany improvements in access to phonetic structure. It explains how these perceptual changes appear to be related to other aspects of language development. Evidence is provided that these changes result from adequate language experience in…
