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.

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 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)

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)
