On the interaction between phonological awareness and reading acquisition: It's a two-way Street.

We have investigated the reciprocal influence of reading acquisition and phonemic awareness. Using a between-grades quasi-experimental design, we have found that learning to read is the most important factor that accounts for the drastic improvement of phonemic segmentation skills during the first year of schooling. On the other hand, we found that improving phonemic skills in kindergarten facilitated reading acquisition in children at risk for developing reading disorders. We suggest that, for most children, exposure to the alphabet automatically triggers phonemic awareness, which is a necessary condition for efficient acquisition of reading. However, the emergence of phonemic awareness requires a previously developed sensitivity to phonology, which in some children may be absent. The present data suggest that, if phonological skills are absent, they may be developed in preschoolers by explicit training, thereby preventing failure in reading acquisition.
