I am generally positive about Muysken's (M) approach, and the potential use of unifying various seemingly related phenomena is obvious. The approach could also serve as a tool in determining to what extent these phenomena actually are sides of the same coin (I am somewhat less convinced of this than most contact linguists).

Pieter Muysken's keynote paper, "Language contact outcomes as a result of bilingual optimization strategies", undertakes an ambitious project to theoretically unify different empirical outcomes of language contact, for instance, SLA, pidgins and Creoles, and code-switching. Muysken has dedicated a life-time to researching, rather…

This study examined the nature of bilinguals' conceptual representations and the links from these representations to words in L1 and L2. Specifically, we tested an assumption of the Bilingual Dual Coding Theory that conceptual representations include image representations, and that learning two languages in separate contexts can result in…

This paper sketches a comprehensive framework for modeling and interpreting language contact phenomena, with speakers' bilingual strategies in specific scenarios of language contact as its point of departure. Bilingual strategies are conditioned by social factors, processing constraints of speakers' bilingual competence, and perceived…

Babcok et al. (2012) claim that Paradis (1994, 2004, 2009) argues that the reliance of late L2 learners on L1 neurocognitive mechanisms increases over time across both lexical and grammatical functions, namely for lexical items as well as rule-governed grammatical procedures, when in fact one can find repeated statements to the contrary in the…

In their keynote contribution, Poplack, Zentz & Dion (henceforth PZD; Poplack, Zentz & Dion, 2011, this issue) propose an interesting "scientific test of convergence" (under section heading: "Introduction") which contains criteria to check whether a particular feature in a given language in contact with another one is…

The findings for adverbs and adverbial phrases in a naturalistic corpus of Miami Haitian Creole-English code-switching show that one language, Haitian Creole, asymmetrically supplies the grammatical frame while the other language, English, asymmetrically supplies mixed lexical categories like adverbs. Traces of code-switching with an English frame…

We report the results from two experiments investigating proficient Japanese-speaking learners' processing of reflexive object pronouns in English as a second language (L2). Experiment 1 used a timed grammaticality judgement task to assess learners' sensitivity to binding Principle A under processing pressure, and Experiment 2 investigated the…

This study reports on the use of (c)overt subjects and subject-verb agreement in Hebrew in the spontaneous speech of a child, EK, acquiring Hebrew and English simultaneously from birth and of five slightly younger Hebrew monolingual controls. Analysis shows that EK's production of pragmatically inappropriate overt subjects is more than three times…

The target article represents a significant advance in the level of sophistication applied to models of bilingual word recognition, and Dijkstra and van Heuven are to be congratulated on this endeavour. Bearing in mind the success of the (computational) BIA model in capturing detailed patterns of experimental data, I look forward to future…

Acquisition by Processing Theory (APT) is a unified account of language processing and learning that encompasses both L1 and L2 acquisition. Bold in aim and broad in scope, the proposal offers parsimony and comprehensiveness, both highly desirable in a theory of language acquisition. However, the sweep of the proposal is accompanied by an economy…

Liliana Sanchez' paper is a welcome contribution to the growing body of literature on Andean Spanish (cf. a recent survey in Muysken, 2004a), welcome both because a well-motivated and clearly described methodology is used and because it is embedded in an explicit theoretical framework. I do not have reservations about the overall conclusions of…

The present article examines one property of bilingual speech--convergence--and strives towards explanatory depth by attending to the insights of the antecedent research in formal linguistics, psycholinguistics, and sociolinguistics. In particular, the paper adopts as a point of departure (and further substantiates) the argument that convergence…
