Three experiments with young children and adults were performed to examine the development of frequency selectivity and to attempt to separate peripheral versus central contributions to frequency selectivity. Results suggested that the shallow notched-noise, fixed-masker-level functions of four-year-old children are probably a result of poor…

The speech of four phonologically disordered children (ages four and five) with place and voice errors affecting initial stop consonants was described through phonological and acoustic analyses. The presence of productive phonological knowledge, as inferred from acoustic data, facilitated rapid generalization of correct production of the treated…

Long-term effects on auditory electrophysiology from early fluctuating hearing loss were studied in 27 children, aged 5 to 7 years, who had been evaluated originally in infancy. Findings suggested that early fluctuating hearing loss disrupts later auditory brain stem electrophysiology. (Author/DB)

Ten children (ages 5-6) and 10 adults participated in discrimination and selective adaptation speech perception tasks using a synthetic consonant-vowel continuum. Results support hypotheses of sensory processing differences in younger, normally developing children compared with adults and show that such abilities appear to be related to speech…
