While there is general agreement that conversational interaction can facilitate interlanguage development, much of the research on interaction has been conducted in experimental laboratory settings. Questions have been raised about the generalizability of the benefits observed in the laboratory to the classroom setting. The current research…

Answers to theoretical questions about the place of input in a formal second language acquisition model are dependent on a distinction between two kinds of learner hypotheses. Type-N hypotheses require "negative evidence" for testing, while Type-P hypotheses are tested on the basis of "positive data" alone. (Author/CB)

Studies employing or investigating the metalinguistic judgments of native and nonnative speakers are reviewed. Their results and methodologies are compared to stimulate reliable and informative applications of such judgments in future research. Metalinguistic judgments are found useful in language acquisition studies, given appropriate controls…

Discusses the current approaches to interlanguage syntax, focusing on the goal of finding consistency and pattern in syntactic variation. Some themes contributing to descriptive approaches include: the transition from morphosyntax acquisition studies to those of more complex syntax, the emergence of syntax from discourse, explicitness, and the…

Examines the word-final, voiceless, stop-sibilant clusters formed by the attachment of -z morphemes to verbs and nouns in the speech production of Japanese learners of English. Reduction is the favored production strategy, but epenthesis is also used. Noun attachments are subject to less error than are verb attachments. (Author/LMO)
