Understanding Variability in Second Language Acquisition, Bilingualism, and Cognition: A Multi-Layered Perspective

This collection brings together linguistic, psychological, and sociological perspectives reflecting on the relationships and interactions of the multi-layered factors impacting second language development and cognitive competence.
The book advocates a system approach as a counterpoint to existing scholarship which has tended to focus on a small set of variables.

The volume outlines theoretical and methodological foundations before looking at the interplay of these different variables at the macro, meso, and micro level.
