There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the Ballet Executive Scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of 0.80 and a split-half Spearman-Brown coefficient r[subscript SB] = 0.81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a Self-Regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF. (Contains 1 table and 1 note.)
