Description
Summary:Results from a longitudinal correlational study of 244 children from kindergarten through 2nd grade indicate that young children's phonological processing abilities are well-described by 5 correlated latent abilities: phonological analysis, phonological synthesis, phonological coding in working memory, isolated naming, and serial naming. These abilities are characterized by different developmental rates and remarkably stable individual differences. Decoding did not exert a causal influence on subsequent phonological processing abilities, but letter-name knowledge did. Causal relations between phonological processing abilities and reading-related knowledge are bidirectional: Phonological processing abilities exert strong causal influences on word decoding; letter-name knowledge exerts a more modest causal influence on subsequent phonological processing abilities.
