Purpose: Vocalization development has not been studied thoroughly in infants with early-identified hearing loss who receive hearing aids in the 1st year of life. This study sought to evaluate the relationship between auditory sensitivity and prelinguistic vocalization patterns in infants during the babbling stage. Method: Spontaneous…

Discusses (1) the process of early language development, giving specific attention to problematic aspects of a vocabulary for audition; (2) elicitation and instruction tasks used in the study of language acquisition; and (3) an investigation designed to compare language acquisition for dimensions of visual, spatial, and tactual perception with…

Argues that evolution of the phonological systems of natural languages and the typology of distinctive features is based on perceptual discontinuities of the auditory system. It is suggested that neonates rely on these innate sensitivities for acquisition of sound systems and that some phonological variation in early child phonology results from…

An auditory rhyme detection task was employed to examine orthographic code development in 27 reading-disabled and 27 normally achieving children (ages 7-11 years). It was concluded that children with a reading disability have a lessened ability to automatically access and make available stored lexical information relating to orthography.…

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…

The Wernicke-Lichtheim-Geschwind (WLG) theory of the neurobiological basis of language is of great historical importance, and it continues to exert a substantial influence on most contemporary theories of language in spite of its widely recognized limitations. Here, we suggest that neurobiologically grounded computational models based on the WLG…

A distinction is made between the acquisition of phonetics and of phonology. Their interaction and the ways in which they interfere with each other are discussed. Data on the acquisition of English fricatives for several children are given, and are analyzed separately for the phonological and phonetic aspects of acquisition. (Author/CLK)

Children, four, six, eight, and twelve years old, and adults participated in a study of judgments of syllable similarity. Subjects listened to a disyllabic nonsense unit (the standard) followed by two comparison stimuli; they were then asked to choose the comparison stimulus "most like" the standard. Changes between the comparison stimuli and the…

Research findings concerned with the relationship between the child's oral language behavior and learning to read are described. A cognitive-biological approach to the child's perceptual system development is taken, and data are presented to support both the developmental point of view of language development and the point of view that the child…

This report describes the proceedings of a conference that brought together 20 psychologists and psycholinguists to present their particular research interests and to attempt to find communalities of thinking through discussion of "The Perception of Language." One position held that thinking is merely subvocal speech, and that at the base of all…

Adults and 4-year-old children were tested to determine whether the children were able to decode sets of familiar minimal pairs as well as adults. They listened to words spoken in a normal voice and a whisper. Indications were that the 4-year-old's perceptual mastery of English phonology is not yet complete. (SW)
