The effect of first language transfer on second language acquisition and learning has been a major theoretical concept in second language research and pedagogy since the 1950s. In order to give a historical perspective, the authors offer a brief presentation of some of the major topics from the broad spectrum of issues that have been examined by…

In order to investigate the internal factors present in the interlanguage of learners of English as a foreign language, a qualitative research study was implemented to analyze the written productions of college students. The main objective of this case study was to identify the type of errors the students made and suggest the cognitive reasons…

This book examines key issues in theories of what language is and what happens in the mind during second language acquisition (SLA), inspiring readers to think in new and exciting ways about language learning and teaching. Chapters, written by both established and rising star scholars, provide cutting-edge insights and new empirical findings on…

This interlanguage study examines the L2 mental lexicon of Thai EFL learners with different degrees of language exposure--i.e., the high exposure group and the low exposure group. The scores from the English Language Exposure (ELE) Questionnaire were used to select the two groups of participants. To explore the lexical processing and the…

This paper examines possible psycholinguistic mechanisms governing stem vowel changes of irregular verbs in intermediate English learners of German as a foreign language (GFL). In Experiment 1, nonce-infinitives embedded in an authentic fictional text had to be inflected for German preterite, thus testing possible analogy-driven pattern…

This article offers the author's commentary on the Multiple Grammars (MG) language acquisition theory proposed by Luiz Amaral and Tom Roeper in the present issue. Multiple Grammars advances the claim that optionality is a constitutive characteristic of any one grammar, with interlanguage grammars being perhaps the clearest examples of a…

This article presents a generative analysis of the acquisition of formulaic language as an alternative to current usage-based proposals. One influential view of the role of formulaic expressions in second language (L2) development is that they are a bootstrapping mechanism into the L2 grammar; an initial repertoire of constructions allows for…

Optionality is a central phenomenon in second language acquisition (SLA), for which any adequate theory must account. Amaral and Roeper (this issue; henceforth A&R) offer an appealing approach to it, using Roeper's Multiple Grammars Theory, which was created with first language in mind but which extends very naturally to SLA. They include…

Analysing the effects of second language (L2) production on L2 learners' interlanguage (IL) modifications is the main scope of this paper. For this purpose, English L2 learners' output production and IL modifications in performing two different task types, one-way and two-way tasks, are compared. The one-way task used in this study was a story…

Han's (2009, 2013) selective fossilization hypothesis (SFH) claims that L1 markedness and L2 input robustness determine the fossilizability (and learnability) of an L2 feature. To test the validity of the model, a pseudo-longitudinal study was designed in which the errors in the argumentative essays of 52 Iranian EFL learners were identified and…

The new developments in syntactic theory under Minimalism reconsiders the relation between the language faculty and general cognitive systems whereby language acquisition is accomplished by the interaction of Chomsky (2005)'s three factors: (F1) a minimally specified UG (Genetic endowment); (F2) Primary Linguistic Data (PLD), i.e., input; and (F3)…

The approach adopted can be characterized with respect to three types of problems in interlanguage studies: the choice of perspective, the relationship between learning and communication, and the ontological status of classes of interlanguage phenomena. This description of processes and strategies is based on the learner's viewpoint. Strategies…

Reviews research on the psycholinguistic processes underlying second-language learning, especially as it relates to the concept of interlanguage and the contributions made by sociolinguistics, neurolinguistics, and cognitive psychology. (MSE)

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.…

Argues against the current oral proficiency testing approach in favor of an approach in which researchers come to understand what it means for real speakers to interact with each other in the everyday world of human activity. Problematic trends are addressed, and a principled theory of oral proficiency is identified. (DJD)
