Additional language (L2/Ln) research largely focuses on learners whose first languages are spoken and who are learning additional spoken languages. In the past few decades, sign languages have become increasingly popular for hearing students in schools. These students must not only learn the vocabulary and grammar of sign languages but also manage…

This study investigates feature acquisition and feature reassembly associated with Clitic Left Dislocation (CLLD). The article compares the acquisition of CLLD in second language (L2) Italian to L2 Romanian to examine effects of first language (L1) transfer, construction frequency and the type of interface involved (external vs. internal…

In the history of psycholinguistics, there are traditional accounts that have been told about language learning and processing. These accounts revolve around the constraints imposed by the age of language learning and by universal principles that are assumed to be natively given. The contribution of Brian MacWhinney and his collaborators has been…

Third language (L3) lexical acquisition is still underexplored. In this article I overview theoretical and empirical evidence on L3 lexical acquisition and the role of cross-linguistic influence (CLI) in learning L3 words. I explain the mechanism of CLI as resulting from language co-activation in the multilingual learner's/user's mind.…

The burgeoning field of third language (L3) acquisition has increasingly focused on intermediate stages of language development, aiming to establish the groundwork for comprehensive models of L3 learning that encompass the entire developmental sequence. This article underscores the importance of a robust epistemological foundation, advocating for…

The current study proposes a new approach to weakness identification in diagnostic language assessment (DLA) for speaking skills. We also propose to design actionable and contextualised diagnostic feedback through the systematic integration of feedback and remedial learning activities. Focusing on lexical use in second language speaking, the…

This study investigates the interpretation of disjunction words (Italian 'o') in negative sentences by Italian monolingual and bilingual (L1 Italian - L2 English) children and Italian adults. Participants were asked to judge Italian sentences corresponding to the English sentence 'This animal did not eat the carrot or the pepper'. According to the…

Given the importance of collocational knowledge for second language learning, how collocation learning can be facilitated is an important question. The present study examined the effects of three different practice schedules on collocation learning: node massed, collocation massed, and collocation spaced. In the node-massed schedule, three…

Extensive evidence indicates that early vocabulary skills predict later reading development among monolingually developing children. Some evidence suggests that a relationship between vocabulary and later reading also holds across languages among children whose home language differs from the school language. However, these findings have been mixed…

This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…

Reading ability in English is decisive in determining the academic achievement of university students who study the English language, or any other subject in English. Extensive research has been conducted to explore whether ESL/EFL reading problems are language-specific or general reading problems. In this regard, previous research on the…

While it has been shown that socioeconomic status (SES) is important for children's literacy development in their first language (L1), less is known about its association with reading in a second language (L2). The present study examined the different effects of SES on the acquisition of reading in Chinese as L1 and English as L2 from ages 7 to…

This study examined the long-term effect of L1 reading achievement on L2 reading achievement while assessing the mediating roles of L1 print exposure and L2 aptitude measured by the Modern Language Aptitude Test (MLAT). Structural equation modeling was used to determine the direct and indirect effects of L1 reading achievement on L2 reading…

Relative clauses have long been examined in research on first (L1) and second (L2) language acquisition and processing, and a large body of research has shown that object relative clauses (e.g. 'The boy that the girl saw') are more difficult to process than subject relative clauses (e.g. 'The boy that saw the girl'). Although there are different…

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.…
