In early childhood and older adulthood, bilinguals generally show better performance on executive function tasks than their monolingual counterparts, but in the young adult population, these differences are infrequently observed. The aim of this inquiry was to compare performance on a modified flanker task for monolingual and bilingual adolescents, a time when the executive functions are still developing. The findings add to the growing body of literature examining bilingualism and executive control in the adolescent population.
