Data on speech, language, performance IQ, school placement, and behavior are presented on 18 subjects diagnosed in childhood as "aphasic" and followed through adolescence. Results revealed slow but steady growth in language with expressive skills showing more rapid progress than comprehension. Performance IQ was highly correlated with language…

The article reviews existing clinical tests of speech perception, describes behaviorally defined procedures for assessing the skill in normal and language disordered children, and notes the need for a more cohesive framework for the development of speech perception. (CL)

Summarizes a model of phonology acquisition based on child speech development. Suggests that a categorization of the kinds of phonological changes which occur during the acquisition period leads to parallels between the mechanisms of phonological change in children and adults. (PMJ)

Examines literary acquisition in a congenitally speechless child. Explains that in spite of a complete oral apraxia, the child developed normal intelligence and acquired complete mastery of reading and writing skills. Notes that though both his verbal memory and metaphonological skills were surprisingly preserved, he showed relative impairment in…

Examines the phonetic patterns and linguistic development of an infant who was tracheostomized during the period that infants normally begin to produce syllabic vocalization. It was found that the infant had developed only a tenth of the canonical syllables expected in normally developing infants, a small inventory of consonant-like segments, and…

Conversational samples were elicited from three-, four-, and five-year-old normal-speaking children and speech rates were measured by the traditional overall method and by the articulatory rate method which uses only fluent sequences. The clinical utility of normative rates is discussed with regard to fluency assessment and intervention.…

Investigation into age-related differences in production of fricative-vowel syllables with 10 adults and 30 children (ages 3, 5, and 7) found that age-related differences in vocal-tract geometry didn't explain age-related differences in vowel effects on fricative noise; children master intersyllabic gestural organization prior to intrasyllabic…

In earlier work we have shown that adults, infants, and cotton-top tamarin monkeys are capable of computing the probability with which syllables occur in particular orders in rapidly presented streams of human speech, and of using these probabilities to group adjacent syllables into word-like units. We have also investigated adults' learning of…

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…

The difficulties and differences of the Hebrew speech of nine children (ages 7 through 11) with severe hearing impairments were compared with the speech of seven children (ages 4-8) without hearing impairments. Each child was asked to name the objects in 20 colored pictures. From the 20 objects, words were selected which included the five main…

Results are reported of a study of voice onset time characteristics of stops in initial clusters in American English words produced by children and adults. (Author/RM)

The study was designed to measure language, cognitive, perceptual, and oral-motor abilities in 17 preschoolers referred for speech-language evaluation because of unintelligible speech. Ss were administered a test battery which included tests of hearing, coarticulation, vocabulary, speech sound discrimination, and oral examination of the speech…

The paper describes the potential of cued speech to provide verbal language and intelligible speech to severely hearing impaired students. The approach, which combines auditory-visual-oral and manual cues, is designed as a visual supplement to normal speech. The paper traces the development of cued speech and discusses modifications made to the R.…

SEVERAL BASES FOR STRENGTHENING THE LANGUAGE DEVELOPMENT PROGRAM IN PRIMARY GRADES WERE CONSIDERED. FROM RECENT STUDIES THAT HAVE RECORDED AND ANALYZED ACTUAL SPEECH SAMPLES OF PRESCHOOL AND SCHOOL CHILDREN, THREE ASSUMPTIONS CONCERNING CHILDREN'S LANGUAGE WERE MADE. FIRST, BY THE AGE OF THREE, MOST CHILDREN HAVE LEARNED THE BASIC STRUCTURE OF THE…

The bibliography lists materials dealing with the communicative behavior (speech, hearing, language) of the mentally retarded. Each entry is classified according to one or more of the following categories: speech and language behavior; assessment of speech and language; hearing (assessment, problems, rehabilitation, research); habilitation…
