The second volume in the Vancouver Studies in Cognitive Science series, this collection presents recent work in the fields of phonology, morphology, semantics, and neurolinguistics. Its overall theme is the relationship between the contents of grammatical formalisms and their real-time realizations in machine or biological systems. Individual essays address such topics as learnability, implementability, computational issues, parameter setting, and neurolinguistic issues. Contributors include Janet Dean Fodor, Richard T. Oehrle, Bob Carpenter, Edward P. Stabler, Elan Dresher, Arnold Zwicky, Mary-Louis Kean, and Lewis P. Shapiro.
