Grammatical complexity has been established as a key indicator of language and writing development (Ortega 2003; Bulté and Housen, 2014; Crossley and McNamara 2014). The present study uses the Register-Functional approach to complexity (Biber et al. 2022) to compare the development of L1 English and L2 English writers across year of study and…

This article sheds light on the linguistic and extralinguistic conditions that determine the likelihood of L1 grammatical attrition in late sequential bilinguals. We explore whether aspectual interpretations associated with the present tense may be a vulnerable area for the native grammar of 30 late Spanish-English bilinguals who have settled in…

Histories of colonization conjointly with the current economic global climate have enabled English to become a dominant global language. The desire for citizens to attain English language proficiency on a nation-wide level is a common pursuit in developing countries, including the island nations of the South Pacific where English competency is…

A central question in multilingualism research is how multiple languages interact. Most studies have focused on first (L1) and second language (L2) effects on a third language (L3), but a small number of studies dedicated to the opposite transfer direction have suggested stronger L3 influence on L2 than on L1 in postpuberty learners. In our study,…

Previous research has shown that bilinguals respond differently to moral dilemmas posed in each of their languages, tending to make deontologically-based decisions (based on right or wrong) in their first language and utilitarian decisions (bringing about the most good) in their second language. In the present study, we tested several predictors…

This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

This study examined the role of parents' early home language use in the English reading development of emergent bilinguals (N = 3,058) and how their relations are moderated by children's oral English language proficiency using longitudinal data from kindergarten to eighth grade (ages 6-15 years). Results from multi-group latent basis growth models…

This study explored the family language policy, bilingual parenting profiles, and the predictors among Chinese parents in Singapore. Altogether 175 parents of Chinese-English bilingual preschoolers (aged 2;6-5;6) were sampled and surveyed. The research results indicated that: (1) a majority of the parents (93.7%) believed in early bilingualism but…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

This brief report presents the results of a re-analysis of data by Yi, Man, and Maie (2023), who investigated L1 and L2 intuitive knowledge of phrasal frequency and collocation strength in multiword sequences. We utilized an individual-differences approach and examined which participant variables (age of onset, length of residence, language use,…

This dissertation investigated how four factors -- the degree of L2 experience, L1 sound structure, age difference in L1 language development and age of L2 exposure -- affect the perceptual cue weighting of duration and spectral differences for English tense-lax vowel contrasts. Four major hypotheses were tested: desensitization hypothesis (DH)…

Processing of emotional meaning is crucial in many areas of psychology, including language and music processing. This issue takes on particular significance in bilinguals because it has been suggested that bilinguals process affective words differently in their first (L1) and second, later acquired languages (L2). We undertook a series of five…

Polysemy, or the property of words having multiple meanings, is a prevalent feature of vocabulary. In this study we validated a new measure of polysemy knowledge for children with English as an additional language (EAL) and a first language (EL1) and examined the relationship between polysemy knowledge and age, language status, and reading…

Feeling like a different person when speaking different languages has been investigated before and attributed to several linguistic as well as psychological factors. Language proficiency, the context of language acquisition, personality traits, emotional intelligence, and the topic of conversation as well as the interlocutor have been found to…

As plurilingual/multilingual research advances, factors that contribute to or hinder individual's flexible language use are still underexplored. Questions such as "Why do some people identify as plurilingual and pluricultural while others do not?" and "What factors contribute to high levels of plurilingual and pluricultural…
