The impact of language on the relationships between phonological awareness and word reading in different orthographies: A test of the psycholinguistic grain size theory in bilinguals

The relationships among first language (L1) and second language (L2) phonological awareness and reading skills were examined in English L2 learners with a variety of L1s, specifically Spanish, Portuguese, and Chinese (maximum N = 252). Longitudinal and concurrent relations between word reading and subcomponents of phonological awareness (i.e., syllable, onset-rime, phoneme, and, where applicable, tone awareness) were examined in kindergarten and first and second grades. The relationships between reading and specific subcomponents of phonological awareness were associated with the orthography being read, English or the L1. Phonological awareness subcomponents related to English reading were generally similar for the three English L2 groups, despite differences in the orthographies of learners' native language. The findings support the psycholinguistic grain size theory with regard to links between phonological sensitivity and the sound-symbol correspondences used to read the specific languages.
