Bilingualism is one of many phenomena that have received substantial attention in relation to human cognition; yet the findings have been diverse. The purpose of the present study was to examine the relationship between bilingualism and domain-general cognitive functions, looking at both behavioral and cortical differences in 70 college-aged participants. In particular, we investigated executive functioning, language processing abilities, and working memory, using the Stroop Task, the Lexical Decision Task, and the Sternberg Working Memory Task respectively, while brain activity was measured simultaneously using electroencephalography (EEG). Cognitive performance by linguistic status revealed no behavioral differences between monolinguals and bilinguals on the cognitive tasks. However, bilinguals did demonstrate significantly enhanced cortical reactivity in frontal regions (i.e., greater response amplitudes) on the decision-making task, but not the attention or working memory tasks, compared to monolinguals.
