Examining a key issue in second language acquisition (SLA) research, this book explores the relation between second language (L2) production and comprehension at the level of processing. The central question underlying this interface is the relationship between grammatical encoding and decoding, namely: are the two modalities of production and comprehension subserved by different types of processors, or by the same syntactic processing module? Proposing an ‘Integrated Encoding-Decoding Model’ of SLA, Anke Lenzing presents the results of a comprehensive empirical study to demonstrate the extent to which the two modalities rely on shared representations and/or shared processes. Through this detailed analysis The Production-Comprehension Interface in Second Language Acquisition sheds new light on the cognitive architecture of human language processing and offers a deeper understanding of the mechanisms at work in the L2 acquisition process.
