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)

Presents arguments for the view that pidginization can be a model of early second language acquisition, decreolization can be a model for later second language acquisition, and creolization is inappropriate for any aspect of this process. (Author/AM)

Investigates the notion of communicative strategies as it has been treated in the literature and then attempts a more precise and explanatory redefinition. Provides an overview of the Vygotskyan psycholinguistic research model which this study uses as a theoretical framework. Also presents a new typology of interlanguage. (SED)

A comparison of three models of language learning: the Creative Construction Hypothesis, the Interlanguage Hypothesis and The Approximate Systems Model. Evidence is provided to support the hypothesis that the third model which incorporates both functional and linguistic analysis describes second language learning and explains why learners progress…

Examines Krashen's Monitor hypothesis (claiming that no interface exists between acquisition and learning) and finds it inadequate due to the over-restrictive conditions necessary for its use. Alternative acquisition theories and ways in which to monitor under less restrictive conditions are also examined, and a communicative trigger is proposed…

A discussion of research on naturalistic second language acquisition (SLA) focuses on its relationship to the foreign language classroom context. It is argued that to attempt to relate natural SLA to classroom foreign language learning (FLL), a coherent and consistent theoretical framework is needed. The Cognitive-Interactionist Model is developed…

Discusses variation in interlanguage and suggests two hypotheses to explain such variation as multiple internal representations of a form and processing errors. Suggests that second language learners can initially represent new forms as prototype schemas, and that such non-discrete representations are a third source of variation in interlanguage.…

This theoretical study of second language learning is divided into eight sections: (1) "Elements of a Theory of Second Language Learning," (2) "Second Language Learning in the Light of Neurophysiological Findings," (3) "Cognitive Strategies in the Second Language Learning Process," (4) "On Accounting for the Role Played by Affective Factors in…

Viewing language learning as another skill acquisition process allows correction to be seen differently. An "error" occurs when knowledge is faulty, a "mistake" when only the performance is faulty. Mistakes can be corrected when (1) the student desires correction; (2) knows what is correct; (3) knows a mistake has occurred; and…

Errors in second language learning are viewed as evidence of the learner's hypotheses and strategies about the new data. Error observation and analysis are important to the formulation of theories about language learning and the preparation of teaching materials. Learning a second language proceeds by a series of approximative reorganizations…
