Proficiency in second language (L2) has traditionally been linked to grammatical competence. However, as opposed to common misconceptions about language learning, to be proficient in a second language does not only entail the ability to produce grammatically correct sentences, but it also entails the ability to use this language appropriately. 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…

Amaral and Roeper (this issue; henceforth A&R) argue that all speakers -- regardless of whether monolingual or bilingual -- have multiple grammars in their mental language representations. They further claim that this simple assumption can explain many things: optionality in second language (L2) language behaviour, multilingualism, language…

Recent findings in the field of pragmatics have revealed that pragmatic accuracy (knowledge) and pragmatic speed (processing ability) function as two distinct and non-parallel components of pragmatic competence. Anderson's adaptive control of thought--rational (ACT-R) model, which emphasises the development of skill through repeated practice,…

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…

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…

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…

This paper presents an extension of the Multiple Grammars Theory (Roeper, 1999) to provide a formal mechanism that can serve as a generative-based alternative to current descriptive models of interlanguage. The theory extends historical work by Kroch and Taylor (1997), and has been taken into a computational direction by Yang (2003). The proposal…

For learners to communicate efficiently in the L2, they must avoid pragmatic failure. In many cases, teachers' praxis centres on the learner's performance in the L2 or his role as a speaker, which neglects the importance of his role as interpreter of utterances. Assuming that, as hearers, learners also have a responsibility to avoid…

Few, if any, researchers would deny the existence of the developmental stages of language learning. However, there are questions about the applicability and the importance of the stages in pedagogy. Up to this point, these questions regarding the ESL (English as a second language) stages have never been addressed in a Japanese post-secondary…

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…

This article documents a fairly rare kind of interlanguage phenomenon, namely one in which interlanguages exhibit syntactic constructions that are grammatical neither in a learner's native language nor in his or her target language, but are nevertheless typologically attested. The target construction is "wh"-scope marking, a cross-linguistically…

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…

This study investigated the acquisition of the Spanish clitic se by English native speakers in passive, middle, and impersonal constructions. Little research has been done on this topic in SLA within a UG framework (Bayona, 2005; Bruhn de Garavito, 1999). VanPatten (2004) proposed the Processing Instruction (PI) model arguing for the necessity of…

This study contributes to the growing field of research on interlanguage pragmatic development with a study on the development of argumentative discourse ability by second-language learners of German. I will be focusing on "facework"--that is, the use of verbal strategies that allow the speaker to have his or her social identities, particular…
