The volume contains a broad spectrum of papers dealing with current issues in first and second language acquisition. The assumption shared by all authors is that for the process of language acquisition to take place properly, the learner has to have custom tools and procedures that allow her to gain specific knowledge about the language(s) that surround her. Just what these tools and procedures are and how they work on the stimuli the learner receives, is what had driven the work behind this collection of papers. The book is a demonstration that generative approaches to language acquisition are taken in almost all corners of the globe and across many of the subdisciplines of language acquisition. The volume also attests to the fact that the data base which generative linguists draw from has been expanded quite dramatically over the past decades.
