The impact of bilingualism on the executive functioning constructs of inhibition, shifting, and updating remains unclear, with prior findings yielding inconsistent results. Several explanations for the lack of congruency have been suggested, including the dependence on observed variables, the impact of test modality on performance, and the need to…

Bilinguals are able to compose expressions across their languages with seeming ease. This phenomenon, commonly referred to as "code-switching," has challenged both theoretical models in linguistics as well as neurobiological models of language processing. And yet, our models of the bilingual brain and the language processing mechanism…

Previous research suggests that the bilingual experience controlling two languages may transfer to non-linguistic control tasks, resulting in a "bilingual advantage." If this is the case, there should be a neural basis for this transfer (i.e., a region of the brain involved in both types of control). The dorsolateral prefrontal cortex…

The current study aims to investigate how Field independent (FI) and Field-dependent (FD) cognitive styles modulate bilingual language control during a joint language switching task. The cognitive styles were measured by the Group Embedded Figures Test (GEFT). The FI group with a preference for autonomous information processing was sensitive to…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

A key index of top-down control in task switching--preparation for a switch--is underexplored in language switching. The well-documented EEG "signature" of preparation for a task switch--a protracted positive-polarity modulation over the posterior scalp--has thus far not been reported in language switching, and the interpretation of…

Recent research has shown that distinct event-related potential (ERP) signatures are associated with switching between languages compared to switching between dialects or registers (e.g., Khamis-Dakwar & Froud, 2007; Moreno, Federmeier & Kutas, 2002). The current investigation builds on these findings to examine whether contrastive and…
