Discusses the motivation for Universal Grammar (UG), as assumed in the principles and parameters framework of generative grammar (Chomsky, 1981), focusing on the logical problem of first-language acquisition and the potential role of UG in second-language acquisition. Recent experimental research regarding the second-language status of the…

Examines the changes in how researchers perceive the relationship between theories of language and theories of language acquisition. It is determined that a theory of grammar is a necessary component in native language acquisition and may also be required for second-language acquisition. (Author/CB)

Explores the concept of markedness in two different linguistically based approaches to universals in second language acquisition. While typologists define markedness implicationally, current theories of language learnability define markedness in terms of the Subset Principle. (21 references) (Author/CB)

Responds to a reanalysis of study findings that refute the claim that negative evidence can lead to parameter setting in second-language acquisition, presenting empirical evidence from French learners of English, suggesting that positive second-language acquisition data do not guarantee the loss of native language parameter settings.
