Purpose: This study examined the development of timing characteristics in early spontaneous speech of children who were later identified as having reading disability (RD). Method: Child-adult play sessions were recorded longitudinally at 2 and 3 years of age in 27 children, most of whom were at high familial risk for RD. For each speaking turn,…

Thirty kindergarteners, 15 who substituted /w/ for /r/ and 15 with correct articulation received two perception tests and a memory test that included /w/ and /r/ in minimally contrastive syllables. (Author)

Purpose: This study evaluated whether developmental reading disability could be predicted in children at the age of 30 months, according to 3 measures of speech production: speaking rate, articulation rate, and the proportion of speaking time allocated to pausing. Method: Speech samples of 18 children at high risk and 10 children at low risk for…

This paper, supported by a Public Health Research Grant from the National Institute of Mental Health, was presented at the Conference on Symbolic Processes, Akron, Ohio, in October 1970. (VM)

To determine whether an "expectation-of-learning" effect was operative in judging a child's phonetic imitation, two techniques for scoring were used to evaluate sequentially one child's phonetic imitations. (Author)

This paper takes issue with the position that children's phoneme acquisition schedule is dictated primarily by auditory perceptual factors and suggests the alternative position that ease of production accounts for age of acquisition. It is felt that perceptual theory cannot adequately explain phonological development, e.g. three-year-olds produce…

Presents the results of a study of attention as a factor in children's natural and experimental acquisition of articulatory behavior. (TO)

Analysis of speech samples from four-year-old monozygotic and dizygotic twins revealed that the monozygotic twins were significantly more likely to misproduce the same sound on an articulation test than were dizygotic twins. The dizygotic twins were no more likely to share errors than were children who were both genetically and environmentally…

Presents an Ohio experiment in which 30 kindergartners and 76 first graders, all English speakers, attempt to learn to produce three non-English phones. Bibliography. (MB)
