This provocative article raises many important issues that need to be addressed and in so doing will advance the fields of second language (L2) and third language (L3) acquisition in several important ways. Fundamental questions concerning multilingual development persist especially with respect to the role of Universal Grammar in this language…

This response argues against the proposal that novel utterances are formed by analogy with stored exemplars that are close in meaning. Strings of words that are similar in meaning or even identical can behave very differently once inserted into different syntactic environments. Furthermore, phrases with similar meanings but different underlying…

In her keynote article advocating the Linguistic Proximity Model for third language (L3) acquisition, Westergaard (2021) presents several arguments against 'copying and restructuring' in nonnative language acquisition, mechanisms central to Schwartz and Sprouse's (1996) Full Transfer/Full Access model of second language (L2) acquisition. In this…

This commentary discusses the recent keynote article in "Second Language Research" by Westergaard (2021), which extends the Micro-cue Model to second language (L2) and third language (L3) acquisition. The commentary comments on such questions as: What makes a given property easy or hard to acquire? How do learners determine similarity?…

In this commentary, I suggest that it may be helpful to think about the formidable problem space that Westergaard's (2021) Linguistic Proximity Model seeks to address at the three levels of analysis that Marr (1982) famously proposed are needed to understand any complex cognitive system. I argue that at the computational level of analysis, where…

In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on…

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…

Transfer has been discussed from different points of view since the advent of Contrastive Analysis Hypothesis [13], [8]. Mishina-Mori [19] has defied transfer as merging grammatical properties from one language to another. The effect of transfer from a first language (L1) to a second language (L2) or a third language (L3) has been viewed…

This dissertation investigates the acquisition of early verb inflection in child Slovenian from morphosyntactic and morphophonological perspectives. It centers on the phenomenon of root nonfinites, particularly the patterns of omission and substitution errors in verb inflection marking. It argues that every acquisition model needs to account…

A distinction is drawn between representational and processing models of second-language acquisition. The first approach is derived primarily from linguistics, the second from psychology. Both fields, it is argued, need to collaborate more fully, overcoming disciplinary narrowness in order to achieve more fruitful research. (GLR)

The author outlines the construction of a somewhat different machine than that envisioned by Turing (with which it would be possible to converse, presumably by telephone or telegraph, and which would be capable of masquerading as a human being). The machine envisaged by the author would be capable of doing comprehension exercises. Such a machine…

Discusses arguments that support the position regarding the distribution of non-grammatical markings of negation and of "wh"-scope and emphasizes the importance of looking for deep unifying principles in cross-modal studies of American Sign Language in order to further understanding of Universal Grammar.

A novel approach is examined for using developmental sequence data for deciding between Universal Grammar-based and problem solving models of adult nonnative grammatical development. Results support the Universal Grammar-based model of nonnative language acquisition. (19 references) (Author/LB)

Challenges the idea that grammatical representations in second-language development are parametric values that are transferred from the learner's native language, offering learner data incompatible with this view. Advocates a weak transfer model in which lexical and functional projections transfer, but morphology-driven values of features like the…

With its focus on simplification universals, developmental orders, teachability, and functional-grammatical bases for acquisition, the well-known research on German (L2) language acquisition has contributed much to SLA research in general. At the same time, sociolinguistic investigations focus squarely on the difficult social conditions that…
