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.…

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)

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…

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…
