Bilingualism, Culture, and Executive Functions: Is There a Relationship?

The relationship between executive functions (EF) and bilingualism has dominated debate in the field. This debate was characterised by optimism for a bilingual advantage until the last decade, when a steady stream of articles reported failure to find a consistently positive effect for bilingualism. In addition to addressing concerns about study quality, this turn of events has spurred research into other variables that may explain the conflicting findings. While recent studies have focused on sociodemographic variables and interactional contexts such as age, code-switching frequency, and socioeconomic class to account for various group and individual differences, the impact of culture is seldom scrutinised. This paper examines the possible effect of culture among bilingual studies on EF by first contextualising how bilingual EF are studied and outlining the absence of culture as a macro variable, followed by a discussion on how culture and language are often conflated. This paper directs attention to the small but emerging research that tracks the importance of culture as a separate variable from language. This review discusses why macro culture and individual monoculturalism or biculturalism need to be carefully elucidated as a factor that can interact with the bilingual experience in shaping EF.
