Presents data on the past and present state of research on the interlanguage hypothesis, with specific attention to its extension to children. Outlines a dual approach to developing a theory of second language acquisition--a macrobehavioral approach and a neurofunctional approach. Finally, problems for the interlanguage hypothesis are discussed.…

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…

Addresses the issue of how we know what learners know based on evidence from second language (L2) learners' spontaneous speech samples gathered longitudinally. Examines some of the problems involved in the analysis of spontaneous speech, with focus on second language studies within the generative framework. Considers the effects of the comparative…

Examines three experimental studies deriving from contrastive analysis predictions and error analysis insights into deviances from expected target language forms. Each of these studies predate the Interlanguage hypothesis. (CB)

Discusses an alternative framework for handling language testing and proposes some tentative hypotheses concerning principles of language testing. Suggests that taking account of both interlanguage domain engagement and contextualization in testing research, production, and interpretation allows for a richer conceptualization of the language…

Suggests a methodology for studying second language acquisition that is concerned with gaining insight into the use, development, and possible fossilization of interlanguage in important real-life situations. Specific interest is focused on the understanding ability of the non-native speaker to use English in discussing a technical field. (65…

Addresses the principles underlying the merging of interlanguages in multiple-language acquisition. The article claims that there is an "interlanguage logic" in multiple- language acquisition and that one can see the structure of the basic learning strategy in interlanguage creation: "interlingual identification." (seven…

Interlanguage studies in second language acquisition and language for speciic purposes (LSP), though developed independently, often use the same data and could benefit from mutual interaction. Related issues for future research are presented. Contents of articles in this issue are reviewed. (Author/LMO)

This article examines the phenomenon of fossilization in second language (SL) learning and instruction, discussing this process as a form of simplification. Fossilization occurs when particular linguistic forms become permanently established in the interlanguage of SL learners in a form that is deviant from the target language norm and that…

This study builds on research that identified empirical evidence indicating that at least one language for special purposes (LSP) domain and one non-LSP domain are in fact associated with some differential results in the consequent interlanguage (IL) structure of non-native users of English. The current study focuses on the methodological problems…

Six papers on interlanguage are presented. The first, "Language Transfer," experimentally tests Robert Lado's contrastive analysis principles on the transfer of language skills to second language acquisition. The second paper, called "Interlanguage," builds on this work in discussing the structured nature of interlanguage and…
