Abstract Bilingual language control has previously been tested separately in tasks of language comprehension and language production. Whereas these studies have suggested that local control processes are selectively recruited during mixed-language production, the present study investigated whether measures of global control show the same dependence on modality, or are shared across modalities. Thirty-eight Dutch-French bilingual young adults participated by completing two tasks of bilingual language control in both modalities. Global accuracy on mixed-language comprehension was related to mixing costs on bilingual verbal fluency, but only when compared to the L2-baseline. Global performance on mixed-language production was related to forward (L1-to-L2) switch costs. Finally, a significant correlation was found between the mixing cost on verbal fluency and forward switch costs on the comprehension task. The results are interpreted as evidence for the involvement of monitoring processes in bilingual language control across modality. The results also highlight the relevance of language switch directionality.

In communication, different forms of language combinations are possible for bimodal bilinguals, who use a spoken and a signed language. They can either switch from one language to another (language switching) or produce a word and a sign simultaneously (language blending). The present study examines language control mechanisms in language switching and simultaneous bimodal language production, comparing single-response (German or German Sign Language) and dual-response trials (Blend of the German word and the German Sign Language sign). There were three pure blocks, one for each Target-response (German, German Sign Language, Blend), as well as mixed blocks, in which participants switched between all three Target-responses. We observed language mixing costs, switch costs and dual-response costs. Further, the data pattern showed a specific dual-response advantage for switching into a Blend (i.e., a dual-response trial), indicating the specific nature of a blended response in bimodal bilingual language production.

Accuracy Data

Aims: The present study aimed to investigate the effect of contexts (i.e., non-conflicting context versus conflicting context) on bilingual language switch costs during language comprehension. Methodology: Thirty-two unbalance Chinese-English bilinguals completed a modified comprehension-based language-switching task in two contexts. They made a judgement about the colour meaning of the word. In the non-conflicting context all words were presented in white ink, while in the conflicting context the words were printed in an inconsistent ink colour. Data and analysis: Reaction time and accuracy data were analysed using mixed-effects models. Findings/conclusions: Results showed that the switch costs were larger in the conflicting context than in the non-conflicting context. Further, in the non-conflicting context an asymmetrical switch cost with larger costs for the second language was observed as compared to symmetrical switch costs in the conflicting context. Originality: This is the first study that indicates that bilingual comprehension-based language control adapts flexibly depending on the context, just as during bilingual production. Significance/implications: These findings supported and expanded the classic adaptive control hypothesis.

Old Adults

Throughout adulthood, the brain undergoes an array of structural and functional changes during the typical aging process. These changes involve decreased brain volume, reduced synaptic density, and alterations in white matter (WM). Although there have been some previous neuroimaging studies that have measured the ability of adult language production and its correlations to brain function, structural gray matter volume, and functional differences between young and old adults, the structural role of WM in adult language production in individuals across the life span remains to be thoroughly elucidated. This study selected 38 young adults and 35 old adults for diffusion tensor imaging (DTI) and performed the Controlled Oral Word Association Test to assess verbal fluency (VF). Tract-Based Spatial Statistics were employed to evaluate the voxel-based group differences of diffusion metrics for the values of fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD), and local diffusion homogeneity (LDH) in 12 WM regions of interest associated with language production. To investigate group differences on each DTI metric, an analysis of covariance (ANCOVA) controlling for sex and education level was performed, and the statistical threshold was considered at p < 0.00083 (0.05/60 labels) after Bonferroni correction for multiple comparisons. Significant differences in DTI metrics identified in the ANCOVA were used to perform correlation analyses with VF scores. Compared to the old adults, the young adults had significantly (1) increased FA values on the bilateral anterior corona radiata (ACR); (2) decreased MD values on the right ACR, but increased MD on the left uncinate fasciculus (UF); and (3) decreased RD on the bilateral ACR. There were no significant differences between the groups for AD or LDH. Moreover, the old adults had only a significant correlation between the VF score and the MD on the left UF. There were no significant correlations between VF score and DTI metrics in the young adults. This study adds to the growing body of research that WM areas involved in language production are sensitive to aging.

Studies of bilingual speech production suggest that different executive functions (EFs) contribute to the cognitive control of language production. However, no study has simultaneously examined the relationship between different EFs and language control during online speech production. The current study examined individual differences in three EFs (working memory updating, inhibitory control, and task-set switching) and their relationship with performance in a trilingual language-switching task for a group of forty-seven native English (L1) speakers learning French (L2) and Spanish (L3). Analyses indicate complex interactions between EFs and language switching: better inhibitory control was related to smaller L1 switch costs, whereas better working memory was related to larger L1 switch costs. Working memory was also related to larger L2 switch costs, but only when switching from L1. These results support theories of cognitive control that implicate both global and local control mechanisms, and suggest unique contributions of each EF to both global and local cognitive control during language switching. Finally, we discuss the implications for theories of multilingual language control.

The Relationship

AbstractThis study investigates the relationship between mechanisms involved in language control within dual- and single-language contexts by examining whether they are similarly impaired in bilingual PD patients. To do so, we explored the performance of bilingual individuals affected by PD and healthy controls on two linguistic tasks: between-language and within-language switching tasks. We focused on switch and mixing costs as measures of linguistic control.The results indicate that, whereas larger switch costs were observed in PD patients, compared to controls, solely during the between-language task, larger mixing costs appeared during both the between-language task and the within-language task. These results are discussed within the framework of the dual mechanism hypothesis, which suggests that switch and mixing costs are measures of two types of control: specifically reactive and proactive control. Therefore, we conclude that reactive control for switching between languages is domain-specific while proactive control mechanisms are more domain-general.

The Cost

Previous language production research with bidialectals has provided evidence for similar language control processes as during bilingual language production. In the current study, we aim to further investigate this claim by examining bidialectals with a voluntary language switching paradigm. Research with bilinguals performing the voluntary language switching paradigm has consistently shown two effects. First, the cost of switching languages, relative to staying in the same language, is similar across the two languages. The second effect is more uniquely connected to voluntary language switching, namely a benefit when performing in mixed language blocks relative to single language blocks, which has been connected to proactive language control. If a similar pattern could be observed with bidialectals in a voluntary language switching paradigm, then this would provide additional evidence in favor of similar control processes underlying bidialectal and bilingual language production.

Experimental Group

In cued auditory task switching, one of two dichotically presented number words, spoken by a female and a male, had to be judged according to its numerical magnitude. One experimental group selected targets by speaker gender and another group by ear of presentation. In mixed-task blocks, the target-defining feature (male/female vs. left/right) was cued prior to each trial, but in pure blocks it remained constant. Compared to selection by gender, selection by ear led to better performance in pure blocks than in mixed blocks, resulting in larger “global” mixing costs for ear-based selection. Selection by ear also led to larger “local” switch costs in mixed blocks, but this finding was partially mediated by differential cue-repetition benefits. Together, the data suggest that requirements of attention shifting diminish the auditory spatial selection benefit.
