Muysken's article is a timely call for us to seek deeper regularities in the bewildering diversity of language contact outcomes. His model provocatively suggests that most such outcomes can be subsumed under four speaker optimization strategies. I consider two aspects of the proposal here: the formalization in Optimality Theory (OT) and the…

This study examines the second language acquisition of Spanish past tense morphology by three groups of English speakers (beginners, intermediates and advanced). We adopt a novel methodological approach--combining oral corpus data with controlled experimental data--in order to provide new evidence on the validity of the Lexical Aspect Hypothesis…

To investigate potential causes of L2 performance deficits that correlate with age of onset, we use a computational model to explore the individual contributions of L1 entrenchment and aspects of memory development. Since development and L1 entrenchment almost invariably coincide, studying them independently is seldom possible in humans. To avoid…

Despite increasing attention to bilingualism--conferences, publications, grants--linguists are as far as ever from reaching consensus. Is code-switching the alternation between two equally activated languages or is it the insertion of elements from a source language into a recipient language? Can and should we distinguish borrowing and…

This paper investigates the role of amount of current and "cumulative" exposure in bilingual development and ultimate attainment by exploring the extent to which simultaneous bilingual children's knowledge of grammatical gender is affected by current and previous amount of exposure, including in the early years. Elicited production and…

We report on object and action picture-naming accuracy in two groups of bilectal speakers in Cyprus, children with typical language development (TLD) and children with specific language impairment (SLI). Object names were overall better retrieved than action names by both groups. Given that comprehension for action names was relatively intact for…

This study examined how individual differences in cognitive abilities account for variance in the attainment level of adult second language (L2) syntactic development. Participants completed assessments of declarative and procedural learning abilities. They subsequently learned an artificial L2 under implicit training conditions and received…

Jurgen Meisel argues that "grammatical variation...can be described...in terms of parametric variation", and--crucially for his arguments in this paper--that "parameter settings do not change across the lifespan". To this extent he adopts the standard generative view, but he then departs from what he calls "the literature on historical…

This paper investigates the acquisition of syntax in L2 grammars. We tested adult L2 speakers of Spanish (English L1) on the feature specification of T(ense), which is different in English and Spanish in so-called subject-to-subject raising structures. We present experimental results with the verb parecer "to seem/to appear" in different…

In this study, we investigate whether preposition stranding, a stereotypical non-standard feature of North American French, results from convergence with English, and the role of bilingual code-switchers in its adoption and diffusion. Establishing strict criteria for the validation of contact-induced change, we make use of the comparative…

There is a long linguistic tradition in which language change is explained in terms of first language acquisition. In this tradition, children are considered to be the agents of language change, or at least the agents of changes in the underlying grammar. Since the early 1980s, this has been formulated in the (generative) terminology in terms of…

Muysken argues for four general "strategies" that characterize language contact phenomena across several levels of description. These strategies are (A) maximize structural coherence of the first language (L1); (B) maximize structural coherence of the second language (L2); (C) match between L1 and L2 patterns where possible; and (D) use…

In this article, we provide a framework of bilingual grammar that offers a theoretical understanding of the socio-cognitive bases of code-switching in terms of five general principles that, individually or through interaction with each other, explain how and why specific instances of code-switching arise. We provide cross-linguistic empirical…

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…

The finding that speakers of aspect languages encode event endpoints to a lesser extent than do speakers of non-aspect languages has led to the hypothesis that there is a relationship between grammatical aspect and event conceptualization (e.g., von Stutterheim and Nuse, 2003). The present study concerns L1 event conceptualization in 40 L1…
