An independent samplest-test was used to compare monolinguals and bilinguals cognitive flexibility and inhibitory control as measured by the Flanker Task, Simon task, and multitasking task. Therewas a significant difference between bilingual(M= SD= ) and monolingual(M= , SD= ) scores on the Flanker Task response timet( ) = ,p = . In addition, monolingual responses were significantly more accurate in the Simon Task(M = ,SD = ) compared to bilingual responses (M = ,SD= ),t( ) = ,p= . Bilinguals and monolingualsdid or did not differ significantly on the incongruent
