Learnability and the Lexicon

This book provides a critical review of recent theories of semantics-syntax correspondences and makes new proposals for constraints on semantic structure relevant to syntax. Data from several languages are presented which suggest that semantic structure in root morphemes is subject to parametric variation which has effect across a variety of verb classes, including locatives, unaccusatives, and psych verbs.The implications for first and second language acquisition are discussed. In particular, it is suggested that different parametric settings may lead to a learnability problem if adult learners do not retain access to sensitivity to underlying semantic organization and morphological differences between languages provided by Universal Grammar.
An experiment with Chinese-speaking learners of English is presented which shows that learners initially transfer L1 semantic organization to the L2, but are able to retreat from overgeneralisations and achieve native-like grammars in this area.
Suggestions for further research in this rapidly developing area of theory and acquisition research are also made.

Antonella Sorace in Journal of Linguistics 36, 2000:
This book is the first and so far most comprehensive study of the acquisition of argument structure in a second language within a generative framework. It is a fascinating window into the cognitive processes of L2 acquisition. It should find a place on the shelves of anyone interested in the relationship between linguistics and language acquisition.
