The notion that a sensitive period exists for language acquisition has gained support from several studies. This study demonstrates that there exist differing periods of heightened sensitivity for certain aspects of the target language, periods before and after in which the learner is less sensitive to the relevant input.

This study documents the sensitivity of English-French interlanguage to the process-result distinction with respect to the licensing of multiple postnominal genitives, despite a lack of direct positive or negative evidence for this distinction in the input. Documentation argues that the Universal Grammar-governed map between syntactic structures…

Examines the role that Universal Grammar (UG) plays in the early stages of the acquisition of Japanese as a second language (L2) by adults. Addresses whether a nonparametrized principle of UG that is instantiated in the first language (L1) is "active enough" in the early stages of L2 learning to apply to phenomena for which there are no…

Employs a truth-value task to reexamine native-language (NL) transfer among Chinese-speaking second-language (L2) learners of English--that is, where NL or mature L2 permits verb raising. Discussion includes a comparison with the earlier findings of Eubank and Grace (1996) and analysis of developmental and transfer-based explanations for the…

A novel approach is examined for using developmental sequence data for deciding between Universal Grammar-based and problem solving models of adult nonnative grammatical development. Results support the Universal Grammar-based model of nonnative language acquisition. (19 references) (Author/LB)

Examines some consequences of optimality theoretic constraint ranking and violability for the study of phonological development. The empirical base for the study is provided by previously unpublished data from a longitudinal corpus of phonetically transcribed speech from four English-learning children. (Author/JL)

Challenges the idea that grammatical representations in second-language development are parametric values that are transferred from the learner's native language, offering learner data incompatible with this view. Advocates a weak transfer model in which lexical and functional projections transfer, but morphology-driven values of features like the…

Investigates effects of instruction on parameter resetting in second-language acquisition, where the first and second language differ as to the settings they adopt for verb movement. The question addressed is whether instruction on one of a cluster of properties associated with lack of verb movement in English generalizes to another property…
