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.…

Advances in Natural Language Processing (NLP) over the past decade have largely been driven by the scale of data and computation used to train large neural network-based models. However, these techniques are inapplicable to the vast majority of the world's languages, which lack the vast digitized text datasets available for English and a few other…

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…

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…

In this review, we evaluate the claim that translanguaging in the classroom supports the development of the bilingual lexicon by enhancing cross-linguistic transfer. To address this issue, we integrate findings from psycholinguistics and educational sciences in order to identify how effective pedagogical practices for monolingual children can be…

Second language (L2) speakers often experience difficulties in learning words with L2-specific phonemes due to the unfaithful lexical encoding predicted by the fuzzy lexical representations hypothesis. Currently, there is limited understanding of how allophonic variation in the first language (L1) influences L2 phonological and lexical encoding.…

Though Mandarin Chinese dual language immersion (DLI) has been growing rapidly in the U.S., research on this population is still rare. This study explored cross-language transfer of expressive oral vocabulary knowledge and definition skills among students in a Chinese DLI program. We found significant within and cross-language relationships of…

In a recent study, English-speaking L2 learners of German who received explicit instruction made significantly greater improvements in pronunciation and vocabulary than learners who received implicit instruction. Against the backdrop of this work, the present study reports learner preferences and perceptions about implicit and explicit language…

Glossing is a widely used and examined vocabulary learning tool, and one of the major branches of glossing research has compared the relative effects of first language (L1) and second language (L2) glosses on reading comprehension and vocabulary learning. However, the findings in this literature have not been consistent, calling for a…

This study explores whether middle-school students can exploit explicitly addressed crosslinguistic lexical similarities between German and English to learn vocabulary more efficiently. Across six weeks, 260 Swiss German learners of English as a foreign language (17 classes) completed three vocabulary learning tests (T1, T2 and T3). Additionally,…

Chinese has a rich and diverse vocabulary of terms, especially verbs, expressing power relationships. This paper selected 25 power relationship terms from the Chinese Proficiency Scale for International Chinese Education, and used a true-false format to test the differences in acquisition between international students from Confucian cultural…

The application of knowledge to new contexts (i.e., transfer) is a central aim of learning processes and has become a new focus of testing effect research. In a quasi-experimental design, we investigated the transfer of retrieval practice effects on English vocabulary learning on eighth-grade students (N = 182) by applying a typical testing effect…

Background: Although there is a growing body of literature on cognitive and language processing in bilingual children with developmental language disorder (DLD), there is a major gap in the evidence for language intervention. Critically, speech-language therapists are often required to make clinical decisions for language intervention on specific…

Research suggests new foreign language (FL) words are learned more easily if their phonology follows the phonotactic rules of the native language. Very little is known, however, about the impact of orthography on FL learning. This study investigated the cognitive mechanisms supporting the learning of words with familiar and unfamiliar…

Previous research has shown that L1-L2 congruency is a facilitative factor in collocation processing. The present study explores the congruency effect between learners' L2 and L3. Thirty-three proficient Norwegian learners with Lithuanian as their L1 and English as their L2 completed a phase acceptability task consisting of three groups of…
