Sex-identification and sex-typing were examined in some Nigerian primary school children using Draw-A-Person. Subjects were from the Yoruba ethnic group. Sex-role differentiation in the Yoruba culture was outlined. The effects of sex and social class on sex-identification and sex-typing
were examined. The results suggest that Yoruba girls are less likely to show own-sex identification than Yoruba boys (p<.001) and that this tendency is more marked for low-income than ‘elite’ girls (p<.01). Regarding sex-typing, marginal sex differences were observed though
the number of drawings amenable for analysis was too small for meaningful statistical comparisons.
Measurement invariance of the World Assumptions Questionnaire across race/ethnic group, sex, and sexual orientation.
