The articles in this special issue contribute to understanding the interactional grounding of language learning by scrutinizing how patterns of language use emerge and get routinized as dynamic resources for accomplishing actions in co-constructed interaction. Their findings problematize how grammar is represented in second language (L2) teaching…

The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

In this commentary, I question Westergaard's argument that third language (L3) data can be used to decide between theories such as Full Transfer Full Access, involving wholesale transfer initially, and Full Transfer Potential, involving property-by-property transfer. I suggest that much L3 data will be amenable to explanation under either theory.…

In her article, Icy Lee (2019, pp. 524-536) discusses the differences between comprehensive written corrective feedback (CWCF) and focused written corrective feedback (FWCF). She argues that teachers should concentrate more on focused feedback, and highlight and correct only a few grammar errors or issues with organisation, for example, instead of…

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…

It is sometimes claimed that teaching grammar is elitist. This article contends that in actual fact, far from being elitist, grammar is a vital ingredient in the English language teaching mix. Since the Chomskyan revolution in linguistics there has been a school of thought in the English speaking world that the formal teaching of grammar is…

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…

Exemplar-based learning requires: (1) a segmentation procedure for identifying the units of past experiences that a present experience can be compared to, and (2) a similarity function for comparing these past experiences to the present experience. This article argues that for a learner to learn a language these two mechanisms will require…

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…

The syntactic behaviour of human beings cannot be explained by analogical generalization on the basis of concrete exemplars: analogies in surface form are insufficient to account for human grammatical knowledge, because they fail to hold in situations where they should, and fail to extend in situations where they need to. [For Ben Ambridge's…

Purpose: In this reply, we respond to comments on our article "Tracking the Growth of Tense and Agreement in Children With Specific Language Impairment: Differences Between Measures of Accuracy, Diversity, and Productivity." Conclusion: The finite verb morphology composite can be disproportionately affected by frequently occurring…

This commentary critiques Ambridge's radical exemplar model of language acquisition using research from the Longitudinal Study of Early Language, which has tracked the language development of 30+ children with Autism Spectrum Disorders (ASD) since 2002. This research has demonstrated that the children's capacity for abstraction at the grammatical…

The constructive feedback on the author's article has helped him to expand his knowledge on the topic. He would like to clarify here that the purpose of the study was to investigate the effects of extensive reading on the development of Japanese high school learners' linguistic knowledge and reading abilities. The findings revealed that the…

Professor of Second Language Acquisition (SLA) Robert DeKeyser is from the School of Languages, Literatures, and Cultures at the University of Maryland. His research builds bridges between the theory of second language acquisition with major concerns in cognitive aspects such as implicit and explicit learning mechanism, age differences, and…

My study (Lindseth, "The Effects of Form-Focused Instruction on the Acquisition of Subject-Verb Inversion in German") that was published in the Volume 49, No. 1 issue of "Foreign Language Annals" suggested that form-focused instruction that targets a specific structure may help learners progress faster toward accurate use of…
