The independent variable is number of languages spoken and the dependent variable is the participants score on the Stroop task.

Demographic details were also reviewed in relation to gender, age, and the number of languages the participant spoke daily. The executive control was measured on using a Victoria Stroop Task. Results indicated a positive significant relationship between scores on the congruent and incongruent sub-trials of the Stroop task and the number of Languages a Person Spoke. (P = .017), (P=.036). There was a significant difference between the bilingual and monolingual group on the number of incongruent errors obtained by the participants (P=.027). There was a significant main effect of the Stroop task obtained (P=.003).
