Connecting perception and production in early Catalan–Spanish bilingual children: language dominance and quality of input effects

This study investigates perception and production of the Catalan mid-vowel /e/-/ɛ/ contrast by two groups of 4.5-year-old Catalan–Spanish bilingual children, differing in language dominance. Perception was assessed with an XAB discrimination task involving familiar words and non-words. Production accuracy was measured using a familiar-word elicitation task. Overall, Catalan-dominant bilingual children outperformed Spanish-dominant bilinguals, the latter showing high variability in production accuracy, while being slightly above chance level in perception. No correlation between perception and production performance could be established in this group. The effect of language dominance alone could not explain the Spanish-dominant participants’ performance, but quality of Catalan input (native vs. accented speech) was identified as an important factor behind familiar-word production and the inaccurate representation of the target contrast in the lexicon of the bilinguals’ less-dominant language. More fine-grained measurements of experience-related factors are needed for a full understanding of the acquisition of challenging contrasts in bilingual contexts.

Preoperative Assessment of Language Dominance through Combined Resting-State and Task-Based Functional Magnetic Resonance Imaging

Brain lesions in language-related cortical areas remain a challenge in the clinical routine. In recent years, the resting-state fMRI (RS-fMRI) was shown to be a feasible method for preoperative language assessment. The aim of this study was to examine whether language-related resting-state components, which have been obtained using a data-driven independent-component-based identification algorithm, can be supportive in determining language dominance in the left or right hemisphere. Twenty patients suffering from brain lesions close to supposed language-relevant cortical areas were included. RS-fMRI and task-based (TB-fMRI) were performed for the purpose of preoperative language assessment. TB-fMRI included a verb generation task with an appropriate control condition (a syllable switching task) to decompose language-critical and language-supportive processes. Subsequently, the best fitting ICA component for the resting-state language network (RSLN) referential to general linear models (GLMs) of the TB-fMRI (including models with and without linguistic control conditions) was identified using an algorithm based on the Dice index. Thereby, the RSLNs associated with GLMs using a linguistic control condition led to significantly higher laterality indices than GLM baseline contrasts. LIs derived from GLM contrasts with and without control conditions alone did not differ significantly. In general, the results suggest that determining language dominance in the human brain is feasible both with TB-fMRI and RS-fMRI, and in particular, the combination of both approaches yields a higher specificity in preoperative language assessment. Moreover, we can conclude that the choice of the language mapping paradigm is crucial for the mentioned benefits.

Lingual Dominance and Symbolic Power in the Discourse of Using the PeduliLindungi Application as a Digital Payment Tool

This study uses a qualitative method with a 3-dimensional Critical Discourse Analysis approach to N. Fairclough's model and Pierre Bourdieu's constructive structural theory to dismantle linguistic domination and symbolic power. The object of the research developed; the researcher took an object published in the online media portal owned by Tempo.co with the title "The Reason Luhut Wants to Care for Protect as a Digital Payment Instrument. The researcher aims to dismantle the concept of symbolic power in the discourse of using the PeduliLindungi application as a digital payment instrument, to explain the language process as an instrument of power in the discourse of using the PeduliLindungi application as a digital payment instrument, and to explain the influence of language dominance on a person. Based on the results of the study, it can be concluded that language is not only a means of communication but in language, there is an ideology and power, from the discourse on the use of the PeduliLindungi application as a means of digital payment using symbolic power and language as an instrument of power. Luhut Binsar Pandjaitan uses language styles such as paralogistic sentences, repetition figureheads, and metaphors to convince and persuade the interlocutor in his language dominance strategy. The social irregularity in the text is the manipulation of information; his argument is in the form of hegemony which gives the impression that the ability to build premium products and the progress of the Indonesian nation is due to digital payments. From text analysis, Luhut Binsar Pandjaitan inserts ideology during the opening ceremony of the peak of Indonesian Creative Works on September 23, 2021. Luhut Binsar Pandjaitan uses his position as Coordinating Minister for Maritime Affairs and Investments to give his symbolic power.

“I can come up with more things when I’m happy, or especially when I’m angry”

This study examines language preferences to express anger and happiness among 15 Russian Australians belonging to the 1.5 generation, who acquired Russian as first language (L1) and English as second language (L2), after migration during childhood. While most research into these topics has focused on L1-dominant bilinguals, this study offers a novel perspective, as 1.5-generation migrants are generally L2-dominant or multidominant (L1+L2-dominant), and possibly L1 attriters. Semi-structured interviews were conducted and underwent qualitative thematic analyses. From the results it emerges that these speakers mostly express emotions in the L2 or both languages, in line with their language dominance, but their choices do not seem to relate to language emotionality, as the L1 maintains the highest emotional resonance for them. While research on multilinguals’ expression of emotions has mainly focused on anger, this study calls attention to the expression of happiness, and points to the importance of L2-dominant and multidominant multilinguals.

The acquisition of relative clauses by Spanish-Basque learners of L3 English: does dominance play a role?

Several studies in the area of third language acquisition (L3A) have considered various factors influencing this process, but the effect of language dominance has not been thoroughly examined. The main goal of this study is to investigate whether the acquisition of relative clauses (RCs) in L3 English is influenced by language internal factors, such as the syntactic features of the target language, or by external factors in the form of cross-linguistic influence (CLI). A total of 90 participants (40 Spanish-dominant, 40 Basque-dominant, 10 L1 Spanish-L2 English) and 10 native speakers of English completed a production and a comprehension task. Findings show that the L3 learners’ production of RCs seems to be driven by language internal factors, whereas their comprehension appears to be influenced by their previously acquired languages, mainly by Spanish. It is concluded that neither language dominance nor other traditionally considered factors play a determinant role in the acquisition of RCs in L3 English by these participants.

Bilingual Language Control Flexibly Adapts to Cultural Context

How does bilingual language control adapt to the cultural context? We address this question by looking at the pattern of switch cost and reversed language dominance effect, which are suggested to separately reflect reactive and proactive language control mechanisms, in the contexts with culturally-neutral pictures (i. e., baseline context) or culturally-biased pictures (i.e., congruent context where culture matched the language to be spoken or incongruent context where culture mismatched the language to be spoken). Results showed an asymmetric switch cost with larger costs for L2 in the congruent context as compared with the baseline and incongruent contexts, but the reversed language dominance effect was not changed across contexts, suggesting that cultural context plays a critical role in modulating reactive but not proactive language control. These findings reveal the dynamic nature of language control in bilinguals and have important implications for the current models of bilingual language control.

Language dominance affects auditory translation priming in heritage speakers

Late second language (L2) learners show translation priming from the first language to the second (L1-L2), while L2-L1 effects are inconsistent. Typically, late L2 learners are both less dominant in the L2 and acquire the L2 after the L1, making the relative contribution of language dominance and order of acquisition in these results unclear. Here, Cantonese heritage and native speakers are tested in an auditory translation priming paradigm. As heritage speakers first learn Cantonese (L1) but later become more dominant in English (L2), this profile allows for the potential dissociation of dominance and order of acquisition in translation priming. If order of acquisition is the primary factor, stronger priming is expected to occur in the L1-L2 (Cantonese-English) direction; however, if dominance plays a stronger role, priming is expected to occur in the L2-L1 (English-Cantonese) direction. Native speakers showed stronger L1-L2 priming, consistent with previous findings, while heritage speakers showed priming in both directions, but stronger L2-L1 priming. The current results suggest that language dominance is a primary factor in explaining auditory translation priming results and that order of acquisition also plays a role in bilingual lexical processing.

Assessing the evidence for asymmetrical language switch costs and reversed language dominance effects - a meta analysis

Two seemingly counterintuitive phenomena – asymmetrical language switch costs and the reversed language dominance effect – prove to be particularly controversial in the literature on language control. Asymmetrical language switch costs refer to the larger costs for switching into the dominant language compared to switching into the less dominant language, both relative to staying in either one language. The reversed language dominance effect refers to longer reaction times when in the more dominant of the two languages in situations that require frequent language switching (i.e., mixed-language blocks). The asymmetrical language switch costs are commonly taken as an index for processes of transient, reactive inhibitory language control, whereas the reversed language dominance effect is taken as an index for sustained, proactive inhibitory language control. In the present meta-analysis, we set out to establish the empirical evidence for these two phenomena using a Bayesian linear mixed effects modelling approach. Despite the observation of both phenomena in some studies, our results suggest that overall, there is little evidence for the generality and robustness of these two effects, and this holds true even when conditions – such as language proficiency and preparation time manipulations – were included as moderators of these phenomena. We conclude that asymmetrical switch costs and the reversed language dominance effect are important for theory development, but their utility for theory testing is limited due to their lack of robustness and the absence of confirmed moderatory variables.

Clinical Speech fMRI in Children and Adolescents

Purpose In patients with drug-resistant focal epilepsy, surgical resection is often the only treatment option to achieve long-term seizure control. Prior to brain surgery involving potential language areas, identification of hemispheric language dominance is crucial. Our group developed and validated a functional magnetic resonance imaging (fMRI) battery of four pediatric language tasks. The present study aimed at optimizing fMRI data acquisition and analysis using these tasks. Methods We retrospectively analyzed speech fMRI examinations of 114 neuropediatric patients (age range 5.8–17.8 years) who were examined prior to possible epilepsy surgery. In order to evaluate hemispheric language dominance, 1–4 language tasks (vowel identification task VIT, word-chain task WCT, beep-story task BST, synonym task SYT) were measured. Results Language dominance was classified using fMRI activation in the 13 validly lateralizing ROIs (VLR) in frontal, temporal and parietal lobes and cerebellum of the recent validation study from our group: 47/114 patients were classified as left-dominant, 34/114 as bilateral and 6/114 as right-dominant. In an attempt to enlarge the set of VLR, we then compared for each task agreement of these ROI activations with the classified language dominance. We found four additional task-specific ROIs showing concordant activation and activation in ≥ 10 sessions, which we termed validly lateralizing (VLRnew). The new VLRs were: for VIT the temporal language area and for SYT the middle frontal gyrus, the intraparietal sulcus and cerebellum. Finally, in order to find the optimal sequence of measuring the different tasks, we analyzed the success rates of single tasks and all possible task combinations. The sequence 1) VIT 2) WCT 3) BST 4) SYT was identified as the optimal sequence, yielding the highest chance to obtain reliable results even when the fMRI examination has to be stopped, e.g., due to lack of cooperation. Conclusion Our suggested task order together with the enlarged set of VLRnew may contribute to optimize pediatric speech fMRI in a clinical setting.

Proactive language control during bilingual sentence production

Aims and objectives/purpose/research questions: While evidence for proactive language control processes has been found during single word production, very little and conflicting evidence has been observed for such control processes during sentence production. So, the main goal of this study was to investigate whether proactive language control can occur during sentence production. Design/methodology/approach: To investigate proactive language control during sentence production, we relied on a description task in single and mixed language blocks. Data and analysis: Mixing costs and the reversed language dominance effect of language intrusions and filled pauses were used to examine proactive language control. Findings/conclusions: Evidence for proactive language control during sentence production came from the mixing cost effect observed with both language intrusions and filled pauses. Whereas no reversed language dominance effect was observed in mixed language blocks, a significant difference in language pattern was observed between single and mixed language blocks, indicating that proactive language control of the first language might be implemented in mixed language blocks during sentence production. Originality: Unlike the vast majority of studies investigating language control, this study relied on sentence production instead of single word production. Moreover, to the best of our knowledge, this is the first study to examine filled pauses to gain insight into language control. Significance/implications: These data indicate that proactive language control can be implemented during bilingual sentence production.
