Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

This study brings together two previously largely independent fields of multilingual language acquisition: heritage language and third language (L3) acquisition. We investigate the production of fortis and lenis stops in semi-naturalistic speech in the three languages of 20 heritage speakers (HSs) of Italian with German as a majority language and…

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…

This article proposes basic (shared) and extended (nonshared) language cognition in native speakers as a function of two types of extralinguistic attributes: (a) degree of being multilingual and (b) variables related to amount and type of literacy experiences (e.g., level of education). This approach may throw new light on the question of whether…

Whilst the links between learner corpus research (LCR) and Second Language Acquisition (SLA) have long been debated, McEnery et al. (2019. "Corpus Linguistics, Learner Corpora, and SLA: Employing Technology to Analyze Language Use." Annual Review of Applied Linguistics 39: 74-92. doi:10.1017/S0267190519000096) claim that learner corpus…

Research on linguistic variation suggests that usage patterns are deeply embedded in native and non-native speakers' knowledge of grammar. This study explores the transfer of these variable sociolinguistic patterns at the initial stages of third language acquisition. We elicited narratives in Portuguese from two mirror-image groups of sequential…

The present study compared L2 and L3 learners of the same additional language in two parallel case studies framed within a Vygotskyan SCT perspective to examine how foreign language learners' background knowledge impacts on the path of their development. Interactive data were collected on the development of interrogative formation by four Persian…

This paper presents an extension of the Multiple Grammars Theory (Roeper, 1999) to provide a formal mechanism that can serve as a generative-based alternative to current descriptive models of interlanguage. The theory extends historical work by Kroch and Taylor (1997), and has been taken into a computational direction by Yang (2003). The proposal…

This article presents findings from an exploratory research project entitled "Gaelscoileanna and Multicultural classrooms: the potential for transfer to enhance L2 learning experiences". The project focussed on two language immersion contexts in Ireland which, despite obvious differences, share a range of significant commonalities. One…

Learning a third language (TL) brings with it particular pedagogical demands. In the pedagogy of TL learning now emerging, the development of students' metalinguistic and crosslinguistic awareness is of central importance. In particular, emphasis is placed on the benefits of cross-referencing with supporter languages. While comparisons with…

This study investigates transfer at the third-language (L3) initial state, testing between the following possibilities: (1) the first language (L1) transfer hypothesis (an L1 effect for all adult acquisition), (2) the second language (L2) transfer hypothesis, where the L2 blocks L1 transfer (often referred to in the recent literature as the "L2…

Many factors that contribute towards the perception of second language (L2) sounds and the subsequent establishment of L2 phonetic categories have been the focus of past research. However, learning a third language, unlike SLA, may be influenced by additional factors attributed to the presence of two language systems in a bilingual instead of one…

Examines results of a study of samples of babbling production of 6, 8, and 10-month-old infants from French, Arabic, and Cantonese backgrounds. Various judges were asked to identify those infants from their own linguistics community, with the intention of supporting hypothesis of an early influence on babbling of metaphonological characteristics…

A cross-section method was used to study the developmental changes in elementary decoding and encoding processes of 163 Swedish-German bilingual students, whose length of residence in Sweden varied. It was demonstrated that decoding in two languages, expressed in terms of reaction time, develops faster than encoding. (SW)

Of the approximately 40 languages in Uganda, some are very similar to one another and may be to some extent mutually intelligible. Because no one knows how to measure degrees of mutual intelligibility, the authors are attempting to establish reliable techniques which would be not only of practical value for the study of language problems in…
