“…The facilitation effects for identical cognates observed in the pure list and the inhibition effects in the mixed list support this interpretation. This pattern of results for identical cognates further mirrors the findings of a recent fMRI study with the same set of cognates and interlingual homographs that was conducted in parallel with the present study (Peeters et al, 2019). In that study, identical cognates reliably activated the language control network (Abutalebi & Green, 2016) in a mixed list context, but not in a pure task situation.…”

“…This was exactly what was observed in the present study. As reported above, recent neuroimaging findings (Peeters et al, 2019) indeed reveal that non-identical cognates do not reliably activate the language control network in a mixed list context, whereas identical cognates do.…”

“…A reduced proportion of ‘no’ responses should increase the competition effects for interlingual homographs. To keep the participants alert under these circumstances and the experimental design compatible with an fMRI study that used the same materials and procedure (Peeters, Vanlangendonck, Rueschemeyer & Dijkstra, 2019; also see Vanlangendonck, 2012), we included trials in which no stimulus appeared in each task.…”

To test the BIA+ and Multilink models’ accounts of how bilinguals process words with different degrees of cross-linguistic orthographic and semantic overlap, we conducted two experiments manipulating stimulus list composition. Dutch–English late bilinguals performed two English lexical decision tasks including the same set of cognates, interlingual homographs, English control words, and pseudowords. In one task, half of the pseudowords were replaced with Dutch words, requiring a ‘no’ response. This change from pure to mixed language list context was found to turn cognate facilitation effects into inhibition. Relative to control words, larger effects were found for cognate pairs with an increasing cross-linguistic form overlap. Identical cognates produced considerably larger effects than non-identical cognates, supporting their special status in the bilingual lexicon. Response patterns for different item types are accounted for in terms of the items’ lexical representation and their binding to ‘yes’ and ‘no’ responses in pure vs mixed lexical decision.

“…Following brain damage, the competitive process (possibly of inhibitory nature) for lexical selection in the non-dominant language could be affected and this would explain why patients are more impaired in that language. Previous neuroimaging studies in bilinguals found mixed results: some that the control network described for language production (Abutalebi and Green, 2007, 2016; Calabria et al, 2018) is also active during word comprehension and recognition tasks (Peeters et al, 2019), but some other studies suggest that the overlap between the two system is only partial (Abutalebi et al, 2007; Blanco-Elorrieta and Pylkkänen, 2017).…”

Individuals with aphasia frequently show lexical retrieval deficits due to increased interference of semantically related competitors, a phenomenon that can be observed in tasks such as naming pictures grouped by semantic category. These deficits are explained in terms of impaired semantic control, a set of abilities that are to some extent dependent upon executive control (EC). However, the extent to which semantic control abilities can be affected in a second and non-dominant language has not been extensively explored. Additionally, findings in healthy individuals are inconclusive regarding the degree to which semantic processing is shared between languages. In this study, we explored the effect of brain damage on semantic processing by comparing the performance of bilingual individuals with aphasia on tasks involving semantic control during word production and comprehension. Furthermore, we explored whether semantic deficits are related to domain-general EC deficits. First, we investigated the naming performance of Catalan–Spanish bilinguals with fluent aphasia and age-matched healthy controls on a semantically blocked cyclic naming task in each of their two languages (Catalan and Spanish). This task measured semantic interference in terms of the difference in naming latencies between pictures grouped by the same semantic category or different categories. Second, we explored whether lexical deficits extend to comprehension by testing participants in a word-picture matching task during a mixed language condition. Third, we used a conflict monitoring task to explore the presence of EC deficits in patients with aphasia. We found two main results. First, in both language tasks, bilingual patients’ performances were more affected than those of healthy controls when they performed the task in their non-dominant language. Second, there was a significant correlation between the speed of processing on the EC task and the magnitude of the semantic interference effect exclusively in the non-dominant language. Taken together, these results suggest that lexical retrieval may be selectively impaired in bilinguals within those conditions where semantic competition is higher, i.e.,- in their non-dominant language; this could possibly be explained by an excessive amount of inhibition placed upon this language. Moreover, lexico-semantic impairments seem to be at least somewhat related to conflict monitoring deficits, suggesting a certain degree of overlap between EC and semantic control.

“…This issue is relevant in the broader context of the widely debated extent of overlap between brain networks and neurocognitive mechanisms functionally involved in executive control and language control. Neuroimaging work indicates that the language control network, which subserves control operations when bilinguals produce (Abutalebi & Green, 2008Luk, Green, Abutalebi, & Grady, 2012) and comprehend language (Peeters, Vanlangendonck, Rueschemeyer, & Dijkstra, 2019), overlaps with the network implicated in executive control more generally (e.g., Abutalebi et al, 2011;Blanco-Elorrieta & Pylkkänen, 2016, 2017Branzi, Della Rosa, Canini, Costa, & Abutalebi, 2016;De Baene, Duyck, Brass, & Carreiras, 2015;De Bruin et al, 2014;Coderre, Smith, Van Heuven, & Horwitz, 2016;Garbin et al, 2010;Grant, Fang, & Li, 2015;Green & Abutalebi, 2013). The exact degree of overlap, however, is under debate and views differ in whether they posit only partial overlap (e.g., Calabria, Baus, & Costa, 2019;Magezi, Khateb, Mouthon, Spierer, & Annoni, 2012;Timmer, Calabria, Branzi, Baus, & Costa, 2018;Weissberger, Wierenga, Bondi, & Gollan, 2012) or significant overlap between highly similar brain circuits (e.g., Abutalebi & Green, 2016;De Baene et al, 2015;Pliatsikas & Luk, 2016).…”

Bilingual switching between languages and listeners: Insights from immersive virtual reality

Perhaps the main advantage of being bilingual is the capacity to communicate with interlocutors that have different language backgrounds. In the life of a bilingual, switching interlocutors hence sometimes involves switching languages. We know that the capacity to switch from one language to another is supported by control mechanisms, such as task-set reconfiguration. This study investigates whether similar neurophysiological mechanisms support bilingual switching between different listeners, within and across languages. A group of 48 unbalanced Dutch-English bilinguals named pictures for two monolingual Dutch and two monolingual English life-size virtual listeners in an immersive virtual reality environment. In terms of reaction times, switching languages came at a cost over and above the significant cost of switching from one listener to another. Analysis of event-related potentials showed similar electrophysiological correlates for switching listeners and switching languages. However, it was found that having to switch listeners and languages at the same time delays the onset of lexical processes more than a switch between listeners within the same language. Findings are interpreted in light of the interplay between proactive (sustained inhibition) and reactive (task-set reconfiguration) control in bilingual speech production. It is argued that a possible bilingual advantage in executive control may not be due to the process of switching per se. This study paves the way for the study of bilingual language switching in ecologically valid, naturalistic, experimental settings. 1.1. Language switching: switch costs and reversed language dominance Bilinguals' ability to switch languages on the basis of an external cue has been investigated extensively in studies using the cued languageswitching paradigm (
