Examines the central characteristics of interlanguages that distinguish them from all other natural language systems. It is proposed that, since permeability presupposes an interlanguage norm which is relatively stable, we are forced to gather enough data to establish the overall level of linguistic competence of the learner.

The study sought to examine the effect of lexical aspect and narrative discourse structure on the pattern of acquisition and use of English verbal morphology exhibited by creole-speaking students. Findings indicated that the emergent pattern of morphology in the creole participants' written interlanguage appeared to be influenced not only by…

Six tentative conclusions about the role of extrinsic feedback in interlanguage fossilization are presented and discussed in light of hypotheses made by Virgil and Oller regarding this phenomenon. Extrinsic factors are those characteristics of the learner which are oriented toward the environment and which act as the interface between the learner…

A cybernetic model of factors involved in the fossilization of grammatical and lexical forms in learner grammars is offered. A distinction is made between affective and cognitive dimensions of a multidimensional channel of human communication; and the effect of expected and unexpected feedback on these two dimensions is discussed. (Author/POP)

Reviews research on the effectiveness of recasts in first and second language acquisition, paying particular attention to how recasts have been defined and how their impact has been assessed in observational and experimental studies. Concludes that recasts appear to be most effective in contexts where it is clear to the learner that the recast is…

Using role play and verbal-report data, this study investigates the sequential organization of politeness strategies of 24 learners of Spanish and whether the learners' ability to negotiate and mitigate a refusal was influenced by length of residence in the target community. Refusal sequences were examined throughout the interaction head acts,…

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…

The author's response to James Flege's critique (in this issue of "Language Learning") regarding earlier research on second-language timing patterns is presented. (LMO)

Responds to a previous article that suggests the second-language-acquisition acquisition field has failed to realize academic respectability. Offers an overview of some of the more positive advances in the discipline. Concludes by calling for a whole systems approach to the study of second language acquisition. (Author/JL)

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…

Describes a study on the English language use of native speakers of Arabic and Japanese in three task conditions: completing a written grammar test, participating in an oral interview, and narrating a story. Results support the hypothesis that the utterances of second language learners show systematic variability related to task. (SED)

An attempt is made to describe second language behavior and language transfer in cybernetic terms. This should make it possible to translate language into machine language and to clarify psycholinguistic explanations of second language performance. (PMJ)

This paper presents a case study of the untutored acquisition of English by a 33-year-old Costa Rican male. Three causes for his lack of linguistic development over a 10-month period are considered: ability, age, and social and psychological distance. The third of these is seen as the cause. (Author/POP)

Investigations of Japanese speakers' interlanguage constructions of English existential sentences with a locative sentential topic found a general shift from topic-comment to subject-predicate structures as proficiency increased. (24 references) (Author/CB)
