This book represents concurrent attempts of multiple researchers to address the issue of cross-linguistic transfer in literacy. It includes broad spectrum of languages and reflects a new generation of conceptualizations of cross-linguistic transfer, offering a different level of complexity by studying children who are trilingual and even learning a fourth language. The collection of papers in this volume tried to capture the dynamic developmental changes in cross-linguistic transfer that include such factors as age of acquisition, typological proximity of L1 and L2 (and L3, L4), intensity of exposure to language and reading in ambient and newly acquired language(s), quality of input and home literacy. More stringent methodological considerations allowed to isolate specific constructs that suggest either primary levels of children's metalinguistic abilities (phological awareness that can be applied cross-linguistically) or a more language-specific constructs (morphological awareness) that relies on various factors, including typological proximity, language proficiency and task demands.
