In Corpus Linguistics and Second Language Acquisition, Xiaofei Lu comprehensively reviews empirical studies that employ corpus linguistic methods to examine learner and task variables that condition variation in second language use. These methods enable advanced students and researchers to:

* Understand the effects of various input factors on second language processing and production

* Track group longitudinal trajectories of second language development and the input, learner, and task factors that affect such trajectories

* Profile inter- and intra-learner variability and individual variation in second language longitudinal development.

This book will serve as an excellent resource for students and researchers with interests in corpus linguistics and second language acquisition.
