Specific Contributions of Phonological Abilities to Early Reading Acquisition: Results From a Dutch Latent Variable Longitudinal Study

Contributions of phonological abilities to early reading acquisition were examined in a longitudinal study of 166 Dutch children from kindergarten through 2nd grade. Various phonological abilities, nonverbal intelligence, vocabulary, and letter knowledge were assessed in kindergarten and Grade 1. Reading and arithmetic were examined in 1st and 2nd grades. The importance of individual differences in phonological ability for subsequent reading acquisition changed over time. At first, the effects of phonological abilities increased, but after Grade 1, these effects disappeared. Phonological awareness and rapid naming had independent and specific influences on reading achievement. Verbal working memory was associated with both reading and arithmetic acquisition. The results tend to support an interactive view of the relation between development of phonological abilities and learning to read.
