In a previous study [Schwartz et al. (2005). Written Language and Literacy, 8, 179–207] we showed that early literacy in Russian (L1) facilitated decoding acquisition in Hebrew (L2) among Russian-Hebrew
first graders. The present study examined two alternative explanations for this finding. The first account concerns the general
benefits of an early start in literacy. The second relates to the specific meta-linguistic insights engendered by early exposure
to a fully fledged orthography—Russian. We therefore compared two groups who had acquired literacy prior to the onset of schooling:
bi-literate bilinguals (Russian L1 literates and Hebrew L2 learners) (n = 26) and early-literacy monolinguals (Hebrew-speaking monolinguals) (n = 18). The research was conducted in two stages. First, linguistic, meta-linguistic and cognitive tasks in Hebrew were administered
to all children and in Russian to the bilinguals at the beginning of the first grade. Next, reading and writing skills in
Hebrew were assessed at the end of the first grade. Bi-literate bilinguals showed superior levels of phonological awareness
on an initial phoneme isolation task in Hebrew compared to other three groups. In addition, the bi-literate bilinguals were
found to be superior to the early-literacy monolinguals on measures of word and pseudoword accuracy, which are known to depend
heavily on phonological processing efficiency, but not on fluency and spelling measures, which are more reliant on stored
orthographic information. This pattern of outcomes was attributed to the facilitating effects of an orthography characterized
by a fully fledged alphabet, in contrast to Hebrew’s primarily consonantal orthography, as well as the complex syllabic structure
of Russian. 相似文献
