We examined the predictive value of early spelling for later reading performance by analyzing data from 970 U.S. children whose spelling was assessed in the summer following the completion of kindergarten (M age = 6 years; 3 months). The word reading performance of most of the children was then tested after the completion of Grade 1 (age 7;5),…

This first Japanese twin study of early literacy development investigated the extent to which genetic and environmental factors influence individual differences in prereading skills in 238 pairs of twins at 42 months of age. Twin pairs were individually tested on measures of phonological awareness, "kana" letter name/sound knowledge,…

Newly literate children have a tendency to spell s-stop sequences in words like "spin," "stop," "sky" with B, D, G (SBIN, SDOP, SGY), rather than with standard P, T, K. This observation potentially has implications for theories of English phonology as well as of language and literacy acquisition. Understanding these…

A study of acquisition of the alphabetic principle in 64 preliterate children, aged 3 to 5 years, is reported. It appears that phonemic awareness and grapheme-phoneme knowledge are needed in combination for acquisition of the alphabetic principle. Once gained, alphabetic insight proved relatively robust.

Preschool children at familial risk for reading disability were assessed on cognitive and linguistic variables and compared with preschoolers without familial risk. Risk children displayed performance profiles resembling those of older children with reading disability. Each group received intensive instruction in phonemic awareness and structured…

We conducted behavior?genetic analyses of kindergarten reading, spelling, phonological awareness, rapid naming, and spoken sentence processing in 172 pairs of monozygotic and 153 pairs of same-sex dizygotic twin kindergarten children sampled in the United States and Australia. We also modeled progress from preschool to kindergarten in…

Reports on the development of a test of phonemic awareness suitable for administration to young children. Compares kindergarteners' performance on a measure controlling for global similarity and another measure not controlled. Finds support for the importance of controlling for global similarity when attempting to measure phoneme invariance. (RS)

Reports on a study of Grade 5 children who had been trained in phoneme identity six years earlier. Results reveal that these children were superior to untrained controls on irregular word reading and on a composite list of nonwords, regular words, and irregular words. Preschool instruction in phonemic structure had modest but detectable effects on…

Results of 6 experiments with 109 Australian preschool children favor training in phoneme identity over segmentation as a component of initial reading instruction because it is easier to implement and its relation to alphabetic insight is stronger. Implications for the initial reading curriculum are discussed. (SLD)

Examines the word-reading strategies of a sample of second- and third-grade students in normal classrooms, focusing on the students' relative reliance on decoding versus sight-word associations. Suggests that lack of efficient decoding skills will begin to take a toll on reading comprehension by grade 3. (SR)

Discusses a study of the relationship of Australian elementary school students' word reading strategies to comprehension level, reading time, and phonemic awareness. Reports that performance in reading both irregular and nonsense words is a reasonably good predictor of subsequent performance. Recommends remedial training for students lacking…

Individual differences in measures of prereading skills and in questionnaire measures of 4-5-year-old twins' print environments in Australia, Scandinavia, and the United States were explored with a behavioral-genetic design. Modest phenotypic correlations were found between environmental measures and the twins' print knowledge, general verbal…

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 program to teach young children about phonological structure was evaluated with 64 experimental group and 62 control group preschoolers in Australia. Results support the efficacy of the program and the principle that phonological awareness and letter knowledge are necessary but not sufficient for acquisition of the alphabetic principle. (SLD)
