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…

Bilinguals sometimes outperform age-matched monolinguals on non-language tasks involving cognitive control. But the bilingual advantage is not consistently found in every experiment and may reflect specific attributes of the bilinguals tested. The goal of this dissertation was to determine if the way in which bilinguals use language, specifically…

The left inferior frontal cortex, the caudate and the anterior cingulate have been proposed as the neural origin of language switching, but most of the studies were conducted in low proficient bilinguals. In the present study, we investigated brain areas involved in language switching in a sample of 19 early, high-proficient Spanish-Catalan…
