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…

Preliminary results from data on 146 Australian, 284 American, and 70 Norwegian preschool twins indicate reliable genetic influences on phonological awareness and memory and learning. Vocabulary, grammar, and morphology showed significant shared environment and negligible genetic effects. A print knowledge composite showed genetic and shared…

A study assessed whether the effects of computer-assisted practice on visual word recognition differed for 73 Spanish children with reading disabilities with or without aptitude-achievement discrepancy. Computer-assisted intervention improved word recognition. However, children with dyslexia had more difficulties than poor readers during…

The purpose of this study was to determine whether music instruction was related to significant gains in the development of young children's phonemic awareness, particularly in their phoneme-segmentation fluency. Beginning in January 2004 and continuing through the end of April 2004, each of four intact classrooms of kindergarten children (n =…

Infants under six months are able to discriminate native and non-native consonant contrasts equally well, but as they learn the phonological systems of their native language, this ability declines. Current explanations of this phenomenon agree that the decline in discrimination ability is linked to the formation of native-language phonemic…

The primary aim of this study was to determine whether a phonological awareness intervention promoted oral English proficiency more than a story-reading condition for Spanish-speaking kindergarten children, most of whom were limited English proficient. A second aim was to determine the extent to which change in English proficiency over the course…

This study examines claims regarding the benefits of systematic and explicit phonics programs by comparing literature-based programs with commercial phonics-based programs to determine which best supports second grades' reading strategies and comprehension. Students in literature-based programs performed comparably in their use of graphophonics…

A preliminary study sought to determine whether preschool, kindergarten, and first-grade children's analyses of English words were governed by perception of onsets and rimes or by perception of phonemes within onsets and rimes. Data were from several previous studies that used a 10-word invented spelling task. High percentages of the 135…

This study examined the reading progress under different teaching approaches of 89 children with diagnosed learning disabilities. The learning-disabled children were placed either in an experimental group that received reading instruction with materials that sequenced learning in increasingly complex levels (from letter-sound to word to context…

This study attempts to provide a systematic mapping of the linguistic structural properties of North American Indian languages. The study includes: (1) the history of areal-typological linguistic studies in North America; (2) a framework for the presentation of areal linguistic phenomena in North America; (3) a presentation and discussion of the…

The testing of non-English dominant children cannot be achieved through written examinations that demand reading proficiency and that fail to ascertain the strengths or weaknesses of individual performance. Nor can an oral proficiency test, involving a lengthy tension-inducing interview and relatively inconclusive scoring, provide the information…

This is one of a series of reports intended to make the results of research available and to serve as progress reports. The following abstracts are included: (1) "Learning the Phonetic Cues to the Voiced-Voiceless Distinction: Preliminary Study of Four American English Speaking Children," Mel Greenlee; (2) "Learning the Phonetic Cues to the…

Theoretical considerations of phoneme construction were explored and a study was made of phoneme efficiency for deaf communication in Finland which utilized 128 deaf pupils (77 boys and 51 girls from grades 3 to 8 and from ages 8 to 15). The main factors of defective production were found in visual reception. It was concluded that, on the average,…

The comparatively small vowel inventory of Bantu languages leads young Bantu learners to produce "undifferentiations," so that, for example, the spoken forms of "hat,""hut,""heart" and "hurt" sound the same to a British ear. The two criteria for a non-native speaker's spoken performance are…

The most significant criterion for classifying spelling errors is whether the erroneous form yields the same pronunciation as the intended word. Five categories can be discerned: (1) non-identical pronunciation, non-existent English word; (2) non-identical pronunciation, confusion of existing words; (3) identical pronunciation, English spelling…
