Background: Neurological networks involved in bilingual language control have been extensively investigated. Among the factors that influence bilingual language control, language balance has recently been proposed as a critical one. Nevertheless, it remains understudied how the neural basis of bilingual language control is affected by language balance. Methods: To address this gap, we conducted a meta-analysis of functional magnetic resonance imaging (fMRI) studies on bilingual language control using Ginger ALE, with language balance as a moderating factor. Results: Conjunction analyses revealed a domain-general pattern of neural activities shared by balanced and unbalanced bilinguals, with convergent activation observed in the left precentral gyrus and left medial frontal gyrus. Regarding domain-specificity, contrast analyses did not identify stronger activation convergence in balanced bilinguals compared to unbalanced bilinguals. However, unbalanced bilinguals exhibited significantly stronger convergence of activation in the left middle frontal gyrus, left inferior frontal gyrus, and left precuneus. Conclusions: These findings suggest that language balance can modify the neural mechanisms of bilingual language control, with unbalanced bilinguals relying on more domain-general cognitive control resources during bilingual language control.

In the present study, we set out to examine the effect of background noise on bilingual language comprehension between a person’s first language (L1) and second language (L2). Language control systems seem to systematically engage in bilingual language production, as evidenced by the presence of switch costs with slower responses to switch trials than repeat trials. However, this systematic engagement does not uniformly apply to comprehension, as the involvement of language control in bilingual comprehension may vary depending on external contexts. In two experiments, we investigated how background noise influenced language switching in comprehension for unbalanced Chinese–English bilinguals. Overall, when comprehending words from two languages, participants experienced significant language switch costs across all conditions, but smaller switch costs were observed in the noise condition than in the quiet condition. However, the symmetrical patterns of switch costs were not modulated by background noise. This is the first study that supports the flexibility of bilingual language comprehension depending on the presence of background noise, expanding the adaptive control hypothesis. Full article

Research has established cognate facilitation effects as a robust finding in bilingual adults and children. Recent studies suggest that cognate facilitation also occurs in highly proficient trilingual adults and can even accumulate across languages. The evidence for multilingual children is scarce and inconclusive. This study examines whether and in which direction cognate effects arise in 35 ten-year-old unbalanced trilingual children, who, in addition to their L1 Italian, acquired L2 German and L3 English in a three-way immersion class in the multilingual region of South Tyrol in Italy. We manipulated cognate status, comparing naming accuracy and latencies in both the L1 and the L3 across double, triple, and non-cognates. The results reveal cognate facilitation effects in naming accuracy, but not in naming speed, for all cognate conditions relative to non-cognates. Furthermore, cognate facilitation was restricted to the L3, replicating previously attested asymmetric effects in unbalanced speakers. In sum, the results indicate that cognate facilitation may boost lexical learning in unbalanced trilingual children who acquire the L2 and the L3 in mainly instructed settings. We discuss these findings in relation to the potential role of language proximity, the L2 status factor, and implications for lexical learning in diverse multilingual environments. Full article

Aims: The present study aimed to investigate whether and how the subcomponents of language control during spoken and written productions were modulated by cognitive control. Method: In the current study, unbalanced Chinese–English bilinguals were recruited from a convenience sample at a university to complete the cued language naming task in spoken production and written production, which measured the local language control (as indexed by language switch costs) and the global language control (as indexed by language mixing costs and reversed language dominance effect). In addition, all the participants performed the Simon task, which measured their general inhibitory control ability by calculating the Simon effect, and performed the AX-CPT task to measure their reactive/proactive control preference by calculating their BSI score. All the data were collected using E-prime 2.0 and analyzed in R. Linear mixed-effect model analyses were conducted to reveal the similarities and differences between spoken production and written production for the first-step analysis. Then, the Simon effect and BSI scores were inserted into the mixed-effect models of the switch costs and mixing costs in spoken production and written production, respectively, to explore whether cognitive control can predict the subcomponents of bilingual control. Results: The results showed similar symmetrical switch costs in spoken and written modalities. In contrast, there was a reversed language dominance effect (in the mixed language context) and asymmetrical mixing costs in spoken production but neither in written production. Furthermore, we found that the Simon effect significantly negatively predicted the L2 mixing costs in spoken production, whereas the BSI score significantly negatively predicted both the L1 and L2 mixing costs in written production. Conclusion: The findings indicated that, for unbalanced bilinguals, local language control is shared between two modalities, while global language control is modality-independent between spoken production and written production. More importantly, the findings also suggested that global language control in spoken production relies more on the individuals’ general inhibitory control, while in written production, it relies more on their cognitive control strategy. Global language control in spoken and written productions separately engages specific aspects of cognitive control, which may account for different forms of processing in global language control between speaking and writing.

Previous research points to a major role of L3 proficiency in L3 acquisition whereas language dominance and cognate status in bilinguals remain under-researched. The aim of this paper was to investigate the role of L3 proficiency, language dominance and cognate status on the production of the L3 Polish lateral. The dominance of Ukrainian over Russian was assessed with the use of an adapted version of the Bilingual Language Profile. Proficiency in Polish was gauged by means of a standardized placement test. The stimuli included tokens requiring a clear realization with the Polish lateral divided into four conditions depending on its production in cognates from Ukrainian/Russian. The results revealed that higher L3 proficiency was associated with an increase in target-like lateral productions in L3 Polish. Language dominance accounted for the less typical lateral pronunciations with a tendency to produce more labiovelar approximants by more Ukrainian-dominant speakers and fewer palatalized laterals by more balanced Ukrainian–Russian speakers. A similar lateral pronunciation in the cognates of both background languages influenced lateral production in the L3. Different lateral pronunciations in the cognates of the background languages had an effect on the more Ukrainian-dominant speakers who had a greater tendency to rely on the L1 Ukrainian pronunciation while producing L3 Polish.

Positive and negative moods tend to have differential effects on lexico-semantic processing in the native language (L1). Though accumulating evidence points to dampened sensitivity to affective stimuli in the non-native language (L2), little is known about the effects of positive and negative moods on L2 processing. Here, we show that lexico-semantic processing is differently affected by positive and negative moods only in L1. Unbalanced Polish–English bilinguals made meaningfulness judgments on L1 and L2 sentences during two EEG recording sessions featuring either positive- or negative-mood-inducing films. We observed a reduced N1 (lexical processing) for negative compared to positive mood in L2 only, a reduced N2 (lexico-semantic processing) in negative compared to positive mood in L1 only, a reduced N400 (lexico-semantic processing) for meaningless compared to meaningful L1 sentences in positive mood only, and an enhanced late positive complex (semantic integration and re-analysis) for L2 compared to L1 meaningful sentence in negative mood only. Altogether, these results suggest that positive and negative moods affect lexical, lexico-semantic, and semantic processing differently in L1 and L2. Our observations are consistent with previous accounts of mood-dependent processing and emotion down-regulation observed in bilinguals. Full article

The role of language in numerical processing has traditionally been restricted to counting and exact arithmetic. Nevertheless, the impact that each of a bilinguals’ languages may have in core numerical representations has not been questioned until recently. What if the language in which math has been first acquired (LL^math) had a bigger impact in our math processing? Based on previous studies on language switching we hypothesize that balanced bilinguals would behave like unbalanced bilinguals when switching between the two codes for math. In order to address this question, we measured the brain activity with magneto encephalography (MEG) and source estimation analyses of 12 balanced Basque-Spanish speakers performing a task in which participants were unconscious of the switches between the two codes. The results show an asymmetric switch cost between the two codes for math, and that the brain areas responsible for these switches are similar to those thought to belong to a general task switching mechanism. This implies that the dominances for math and language could run separately from the general language dominance. Full article

One of the key questions of studies on heritage language (HL) transmission is which factors most likely foster the intergenerational transmission of HL and more saliently favor its acquisition in second-generation speakers. The present study explores the effect of the cognitive and affective disposition of first-generation speakers on the subjective HL proficiency level in the second generation of Russian-speaking immigrants in the town of Salamanca, central Spain. Based on a scalar questionnaire which enquires into the language practices, language attitudes and language motivations of the first-generation speakers, the study analyzes the effect of self-categorization, attitudes towards HL utility, and strategies of HL intergenerational transmission in ten mixed families. The main results of the study show that positive HL affectivity is key to assuring proficient HL acquisition in second-generation speakers, while negative HL affectivity systematically drives unbalanced Spanish–Russian bilingualism in children. The final results are consistent with those of other recent studies on affectivity in HL and suggest the importance of positive attitudes towards HL in its transmission. Full article
