This article delves into the intricacies of the relationship between bilingualism and creativity. It provides an overview of past research and examines its methodology. It introduces a multilingual creative cognition theoretical framework that focuses on the cognitive mechanisms underlying creative potential and how these mechanisms might benefit from an individual’s multilingual abilities. The link between multilingualism and creative potential is explained by multilingual developmental factors such as proficiency, age, and sociocultural context of language acquisition, as well as cognitive functions such as language-mediated concept activation, selective attention, code-switching, and metaphor. However, the multilingual creative cognition approach takes a narrow perspective. By synthesizing empirical evidence and theoretical insights, the article proposes a plurilingual creativity framework – a multifaceted approach that transcends traditional bilingualism and creative cognition frameworks. It underscores the significance of a comprehensive language repertoire, multicultural experiences, and intercultural competence as pivotal elements enriching various aspects of creative endeavor. The article also introduces the Plurilingual Intercultural Creative Keys educational program, which aims to develop plurilingual, intercultural, and creative capabilities in educational settings. Through a holistic analysis, this study contributes to a nuanced understanding of the relationship between linguistic and cultural diversity and creativity. It also suggests practical implications for fostering linguistic and creative skills in a globalized context.

English as a second language (L2) has become the medium of instruction in numerous contexts even though many people may have difficulties to read and study in L2. According to the self-regulated framework, metacognitive strategies are essential to achieve successful learning, but they are resource-consuming and their use might be compromised in demanding contexts such as learning in L2. In Experiment 1, nonbalanced bilinguals read high- and low-cohesion texts in L1 and L2 and self-rated their learning using a judgment of learning (JOL). Then, they answered open-ended questions and responded a customized questionnaire regarding their strategies. In Experiment 2, we introduced two bilingual groups varying in L2 proficiency. Overall, participants could adjust their JOLs and detect the difficulty of the texts correctly in L1 and L2. However, results evidenced some nuances in learning strategies related to L2 proficiency. We discuss these findings within the context of the self-regulated learning.

How native (L1) and non-native (L2) readers utilise syntactic constraints on linguistic dependency resolution during language comprehension is debated, with previous research yielding mixed findings. To address this discrepancy, we report two large-scale studies, using self-paced reading and grammaticality judgements, investigating subject-verb agreement and reflexives in L1 English speakers and Arabic learners of L2 English. We manipulated sentence grammaticality and the properties of ‘distractor’ constituents (The key(s) to the cabinet(s) were rusty) in two studies testing number in agreement and gender/number in reflexives. Study 1 showed that L2ers’ performance largely patterned with L1ers’. Although grammaticality effects were smaller for agreement in L2ers than in L1ers, proficiency modulated L2 performance. Study 2 revealed no significant between-group differences. Contrasting some L1 studies, significant distractor effects were only detected for reflexives in Study 1. Together, these results imply that L2ers compute syntactic dependencies similarly to L1ers, and potential differences might be driven by L2 proficiency.

This study longitudinally modeled home language exposure patterns of US Spanish–English bilingual children between the ages of 4 and 12. Participants were 280 Spanish–English bilinguals (95% Hispanic, 52% female) who were followed for up to 5 years using a cross-sequential longitudinal design. Multilevel linear regression models were used to estimate language exposure trajectories across four home language sources (adults, peers, electronic media and literacy activities) and three language modes (Spanish-only, English-only and bilingual). Results demonstrated that Spanish interactions with both adults and peers declined as children aged, while bilingual interactions showed a distinct increase over time. Conversely, media exposure and engagement in literacy activities increased over time, irrespective of the language used. Children’s age of first English exposure and current school English exposure also influenced language contact and use in the home. These findings approximate an 8-year exposure trajectory across a continuum of bilingual experiences.

This systematic review and meta-analysis explore the correlation between foreign language instruction and mathematical skills in young adolescents, highlighting the significance of high school mathematical education and the adaptability of the adolescent brain. Focused on students starting second language programs between ages 8 and 13, following PRISMA guidelines, this review included 25 studies (1978–2020) with 785,552 participants. Using a random-effects model, the overall effect size revealed a statistically significant relationship between our variables, indicating a threefold higher likelihood of passing or achieving higher grades in mathematical tests for language-learning students. Moderating variables analyses identified socioeconomic status (SES) and intervention length as influencers of observed heterogeneity, with SES being the primary factor. Sensitivity analyses, including adding potentially missing studies and removing outliers, confirmed the robustness of the overall effect. Nonetheless, additional research is needed to enhance global diversity and comprehensively understand the interplay between language learning and cognitive function.

The study explored the origin of the age of acquisition (AoA) effect in second language (L2) using ERPs technique. We simulated L2 AoA by manipulating the order at which English pseudowords entered into training. Chinese-English bilinguals (mean age 22.04, range 18–28) learned English pseudowords matched with Chinese (L1) words, investigating the order of acquisition (OoA) effect of English pseudowords and its relationship with the matched L1 words’ AoA. OoA effects were observed in lexical decision, naming and semantic judgment tasks on N170, P200 and N400. Furthermore, OoA effects were modulated by L1 AoA in the semantic judgment task. These results suggested that OoA effects were independent at orthographic and phonological levels but modulated by L1 AoA at the semantic level. The interpretation of L2 AoA effects requires not only the integration of Semantic and Arbitrary Mapping Hypotheses, as well as consideration of the representation and activation characteristics of L2 words.

There is evidence to suggest that the effects of bilingualism on executive functions (EFs) need to be examined along a continuum rather than a dichotomy. The present study addressed this need by examining the influence of different bilingual experiences on executive functioning using a Flanker and Stroop mouse-tracking task that taps into more dynamic cognitive processes than typical behavioral paradigms. We sampled 98 bilingual young adults and investigated conflict and sequential congruency effects (SCEs). We found that mouse-tracking metrics captured links that were not identified with overall reaction times. SCEs were more sensitive to detecting relations between L2 experiences and EF than simple conflict effects. Second-language age of acquisition and L1/L2 switching frequency consistently predicted EF outcomes. This association was moderated by the attentional demands of the task. These findings highlight the complexity of the effects of bilingualism on cognition, and the use of more sensitive measures to capture these effects.

Prior work has yielded mixed findings regarding the relationship between language control and domain-general inhibitory control. Here, we tested the possibility that omnibus language ability would moderate the relationship between language control and inhibitory control in bilingual children. We tested 43 Spanish-English bilingual children (ages 4–5.92 years; 25 females). Children engaged in play-based interactions with their parent, and rates of cross-speaker switches (using a language different from one used by parent) indexed language control. Inhibitory control was measured via a non-verbal flanker task. Analyses revealed that higher frequency of cross-speaker code-switches was associated with better inhibitory control only for children with higher levels of language ability. For children with lower language skills, there was no association between switches and inhibitory control. These findings align with the literature linking cognitive control and language control in bilinguals and extend it to indicate that the strength of the language system constrains this link.

This study investigated how interlocutors’ linguistic competence affected L2 speakers’ lexical alignment and how the interlocutor effect was modulated by speakers’ proficiency. Chinese English as a Foreign Language speakers performed an online text-based picture-naming and -matching task with interlocutors of different perceived linguistic competences: an L1 interlocutor, an L2 interlocutor of higher proficiency or an L2 interlocutor of lower proficiency. We compared the magnitudes of L2 speakers’ lexical alignment across interlocutor conditions and examined whether the interlocutor effect varied with speakers’ L2 proficiency. Results showed that L2 speakers aligned more with the L1 interlocutor than the L2 interlocutor, indicating an effect of interlocutors’ language status (native vs. non-native). Moreover, L2 speakers’ lexical alignment with interlocutors of varying proficiency was differentially affected by their own proficiency levels. This study adds to the existing work by revealing the joint influence of the interlocutors’ competence and the speakers’ L2 proficiency on lexical alignment in L2 communication.

This study examines how word characteristics like frequency, concreteness, part of speech and length predict Dutch vocabulary knowledge in 763 adult migrant L2 learners who vary widely in their educational levels in their L1, from minimal to extensive formal education. While the impact of these features on vocabulary learning is well-documented among tertiary-educated adult and adolescent L2 learners in the academic track of secondary education, its effect on low-educated adult L2 learners has hardly been explored. Findings confirm that word frequency, concreteness and length significantly predict receptive vocabulary knowledge, aligning with prior research. However, the study also reveals variations in the predictive power of word frequency and length among adults with different educational backgrounds. These results highlight the necessity to reassess the applicability of findings from current research on L2 receptive vocabulary, particularly concerning adult learners with reduced educational backgrounds.

In this study, we describe the performance of 62 newly immigrated children to France at a nonword repetition task (LITMUS-QU-NWR-FR) designed to evaluate bilingual children’s syllable structure. Children were between 6;0 and 9;1 and had diverse language backgrounds. They participated in our study during their first year of exposure to French. The majority of our children exhibited a good performance on the task. The variation observed is related to: (i) the properties of the nonwords: items with complex syllables are more difficult, as are items with three syllables in length; (ii) phonological awareness: children with a more developed L2 phonological awareness perform better at the task; and (iii) receptive vocabulary size: children with a larger L2 vocabulary size perform better at the task. Overall, our findings provide support for the argument that the LITMUS-QU-NWR-FR task can be used shortly after the onset of exposure to the L2.

We investigated the extent to which executive functions (EFs) are recruited in language switching in children in a cued picture-naming (CN) task. We expected to find associations between CN and EF tasks measuring inhibitory control and shifting. Another goal was to compare parent-reported children’s everyday language control ability at home with their switching ability in the CN task and EF performance. The participants were mostly 5–7-year-old Norwegian–Spanish and Finnish–Swedish-speaking children (N = 45). The analysis was preregistered. Unexpectedly, the primary accuracy analysis showed positive associations between CN switching costs and EF performance in only one of the EF tests, flanker, and CN mixing costs were predicted only by the color-shape switch costs. Children’s everyday language control ability did not show consistent significant associations with lab measures. Our study provides weak evidence for the view that EFs are engaged in language control when children have some years of bilingual experience.

Previous research suggests that emotion words elicit lower emotional reactivity in languages acquired later in life (LX), prompting bilinguals to make less emotional decisions when responding to emotionally charged moral dilemmas in the LX compared to their first language (L1). This study investigated the influence of word emotionality on bilinguals’ moral judgements by manipulating the degree of emotiveness of the moral questions (i.e., emotive versus neutral conditions) accompanying different types of moral dilemmas (i.e., personal/sacrificial versus impersonal/realistic). Mixed effects logistic regression models revealed that the use of the LX increased the number of utilitarian decisions in both the emotive and the neutral conditions but only in the sacrificial moral dilemmas. Moreover, the emotive questions led to more deontological moral judgements than the neutral questions but only in the L1. Taken together, these findings provide further insight into the impact of emotion on bilinguals’ moral decision-making.

An important question in literacy education is whether reading instruction should focus on whole words or subword constituents. We tested whether this question captures something general across writing systems by examining the functionalities of words and characters in learning Chinese. We introduce a character-word dual-focus instructional approach based on the Character-Word Dual Function model and test its predictions with American undergraduate students enrolled in a beginner-level Chinese course. One group learned new words through dual-focus instruction: characters for pronunciation and words for meaning. A second group followed typical word-focus instruction prevalent in classrooms, learning word-level pronunciation and meaning. Results indicated that while both approaches produced comparable levels of word pronunciation and meaning learning, the dual-focus instruction significantly enhanced character pronunciation and transfer to new word learning. The advantages of dual-focus instruction highlight the importance of learning the subword components through acquiring the systematic structure of the writing system in learning to read.

Prediction is a crucial mechanism of language comprehension. Our research question asked whether learners of Spanish were capable of using word order cues to predict the semantic class of the upcoming verb, and how this ability develops with proficiency. To answer this question, we conducted a self-paced reading study with three L2 Spanish groups at different proficiency levels and one native control group. Among the advanced L2 learners and native speakers, we found that reading times increased after the verb appeared in a word order not strongly associated with its semantic class. Because the only cue to the sentences’ word order was the presence or absence of the object marker a before the first noun, we suggest that these groups use this morphosyntactic cue to anticipate the semantic class of the upcoming verb. However, this pattern of processing behavior was not detected in our less experienced L2 groups.

Language exposure and use (LEU) are widely viewed as key factors in multilingual development, and research highlights the importance of considering not just the frequency and quantity of LEU, but also contextual factors such as when and where a language is used, with whom and why. In this study, we illustrate the complexity of LEU in two contexts (study abroad and migration) by applying sequential mixture modelling to rich Experience Sampling Method data, considering combinations of various aspects of LEU such as language choice, type of activity, quantity, interlocutor characteristics and learner engagement. We argue that together, these methods for data collection and analysis have the potential to significantly strengthen research into LEU and broader language-related development. By uncovering distinct classes of language-related activities and language user profiles, we gain deeper insight into the nature of situated LEU and its relationship to language development among migrants and in study abroad.

Validated yes/no vocabulary tests that measure bilinguals’ language proficiency based on vocabulary knowledge have been widely used in psycholinguistic research. However, it is unclear what aspects of test takers’ vocabulary knowledge are employed in these tests, which makes the interpretation of their scores problematic. The present study investigated the contribution of bilinguals’ form-meaning knowledge to their item accuracy on a Malay yes/no vocabulary test. Word knowledge of Malay first- (N = 80) and second-language (N = 80) speakers were assessed using yes/no, meaning recognition, form recognition, meaning recall and form recall tests. The findings revealed that 59% of the variance in the yes/no vocabulary test score was explained by the accuracy of the meaning recognition, form recognition and meaning recall tests. Importantly, the item analysis indicated that yes/no vocabulary tests assess primarily knowledge of form recognition, supporting its use as a lexical proficiency measure to estimate bilinguals’ receptive language proficiency.

Embodiment theories postulate that language processing inherently engages the sensorimotor system. This study explores the embodiment of action verbs in the second language (L2) and the effects of various L2 experiences (L2 age of acquisition, exposure, dominance, and proficiency) on L2 embodiment. Sixty-one Chinese–English bilinguals participated in two experiments judging semantic relatedness: Experiment 1 involved verb–picture pairs, while Experiment 2 focused on verb–verb pairs. Both experiments were conducted in the participants’ first language (Chinese) and second language (English), with the stimuli depicting actions performed by specific effectors (e.g., mouth, hand, and foot). Results showed that participants took longer to reject mismatched verb–picture pairs and semantic-unrelated verb–verb pairs when the actions shared the same effector (e.g., walk–run) than those involving different effectors (e.g., eat–touch). Moreover, L2 age of acquisition, exposure, and dominance correlated with the L2 embodiment effect, with L2 age of acquisition and exposure modulating this effect. This study enhances our understanding of L2 embodied semantics and illuminates the impact of multidimensional L2 experiences on embodiment.

In cross-linguistic word learning, learning new knowledge based on existing knowledge is a common and lifelong process. This study investigated whether inhibitory control would be conducive to this process. We asked Chinese-English bilinguals to learn new meanings for familiar English ambiguous words within two consecutive days, manipulating semantic relatedness and word frequency to create four categories: high-frequency-unrelated, high-frequency-related, low-frequency-unrelated and low-frequency-related ambiguous words. Participants completed translation recognition and production tests immediately after learning and again one week later, with flanker and stop-signal tasks interspersed to measure their interference inhibition and response inhibition. The results indicated that inhibitory control, particularly interference inhibition, significantly aided in learning new meanings when direct knowledge transfer from existing knowledge was unfeasible. This research enhances our comprehension of individual differences in word learning, offering valuable perspectives for broader theories of word learning and targeted educational interventions.

The language of heritage speakers is characterized by variability and structural innovations compared to the baseline grammar of first-generation immigrants. Although many factors contribute to these differences, this study considers structural priming with structures that do not exist in the majority language as a potential mechanism for language change. The linguistic focus is accusative clitic doubling, which exists in some Spanish varieties, but which is unacceptable in others. Our research examined how flexible heritage speakers’ grammars are compared to baseline speakers, and to what extent heritage speakers adopt structures attested in the diachronic development and in other varieties of their heritage language. In two studies, we tested the acceptability of accusative clitic doubling and primed accusative clitic doubling in oral production. Results showed that heritage speakers of Spanish are somewhat accepting of innovative structures and more sensitive to structural priming compared to baseline speakers, who are generally not.
