The present work presents a critical assessment of claims in recent literature that moribund language varieties exhibit accelerated language decay, and that attrition in individual grammars has a causational relationship with language shift to the majority language. We show these claims to be unfounded. Based on two empirical points taken from…

Usage-based approaches to additional-language acquisition have identified numerous determinants of language learning, two of which were the focus of our study: frequency and cue contingency. Specifically, we examined how an immersion experience may impact sensitivity to these two determinants as reflected in the production of 4,808 pairs of nouns…

This study longitudinally examined the effects of cognitive and sociopsychological individual differences (aptitude, motivation, personality) and the quantity and quality of second language (L2) experience on L2 speech gains in naturalistic settings. We elicited L2 spontaneous speech from 50 Chinese learners of English at the beginning and the end…

Extending previous findings on adult L2 learners' integration of verbal and constructional information, this study investigated how child learners of English as a foreign language produce verbs in target constructions and whether (a) receptive skills and (b) the specific production modality (spoken versus written) modulate the integration process.…

Distributional learning is typically understood as (unattended) tracking of stimulus probabilities. Distributional training with speech yields mixed results and the influencing factors have not yet been fully investigated. This study explored whether prior linguistic experience could have an effect on distributional learning outcomes. Czech and…

Heritage languages (HLs) are acquired in contexts of unbalanced input, or situations in which children receive primary exposure to the family/HL and experience an abrupt shift after the child begins formal schooling. As a consequence, HL speakers normally become more dominant in the environmental language, while the development of the HL is…

The current study examined the degree to which collocation use (i.e., meaningful co-occurrences of multiple words) is related to first language (L1) raters' intuitive judgments of second language (L2) speech. Speech samples from a picture description task performed by 85 Japanese learners of English with varied L2 proficiency profiles were…

The constructionist approach holds that an argument structure construction, a conventionalized form-meaning correspondence of a sentence, allows language users to efficiently access sentential information. This study investigated whether increased sensitivity to constructional information would enable second language learners to efficiently fuse…

To date, a growing number of studies have shown that domain-general auditory processing, which prior work has linked to L1 acquisition, could explain various dimensions of naturalistic L2 speech proficiency. The current study examined the generalizability of this topic to L2 speech learning in classroom settings. The spontaneous speech samples of…

This article contributes to the debate about the appropriate use of corpus data in language learning research. It focuses on frequencies of linguistic features in language use and their comparison across corpora. The majority of corpus-based second language acquisition studies employ a comparative design in which either one or more second language…

This study investigated the predictions of two approaches to second language acquisition. According to the usage-based approach, learner knowledge results from the strengths and weaknesses of input-driven statistical learning. According to the learner-varieties approach, pragmatic communication principles and language-internal constraints play…

This article focuses on the use of collocations in language learning research (LLR). Collocations, as units of formulaic language, are becoming prominent in our understanding of language learning and use; however, while the number of corpus-based LLR studies of collocations is growing, there is still a need for a deeper understanding of factors…

This study examined the acquisition of a linguistic property that is underrepresented in the input available to second language (L2) learners, namely, interpretation of French strong pronouns as [-animate]. To understand how pronouns are used and interpreted and how this topic is treated in pedagogical grammars, three types of analyses were…

Idealization plays a fundamental role in scientific inquiry. This article examines the case for maintaining the claim that the second language acquisition (SLA) of grammatical structures such as negation manifests identifiable stages of acquisition. It proposes that, while research has demonstrated the need for de-idealization, there is no need to…

Adequately responding to linguistic diversity in the classroom is imperative in European school contexts, not least because of current migratory movements. This article presents the results of an intervention study with primary school English-foreign-language learners in Germany (N = 42, M[subscript age] = 8.70 years) from linguistically diverse…
