Competence-based theories of island effects play a central role in generative grammar, yet the graded nature of many syntactic islands has never been properly accounted for. Categorical syntactic accounts of island effects have persisted in spite of a wealth of data suggesting that island effects are not categorical in nature and that…

Through corpus analysis and experimentation, this article demonstrates that both grammatical complexity (heaviness) and discourse status (newness) simultaneously and independently influence word order in two English constructions. Argues that heavy and new constituents facilitate the processes of planning and production. (Author/VWL)

Presents two questionnaire experiments that investigated the processing complexity of a variety of nested constructions in Japanese. The results are discussed in terms of the syntactic-prediction locality theory. (Author/VWL)
