In this invited volume, experts in Spanish linguistics who subscribe to the Chomskyian thory of Universal Grammar, along with the editors, approach the general applicability of this model from the perspectives of their subdisciplines: language acquisition, syntax, semantics, phonology, and morphology. Their research points to the verification of the Chomskyian linguistic theory as a general framework for explaining phenomena in language acquistion and use—and, more generally, to the possible development of a model of mind based on linguistic theory. Current Studies in Spanish Linguistics will interest all specialists in Spanish and theoretical linguistics, as well as those interested in cognitive science, psychology, philosophy of mind, and artificial intelligence.
