This chapter summarizes 2 large international research projects, one dealing with gender stereotypes across 25 countries and the second with masculinity and femininity in the self and ideal self descriptions of individuals across 14 countries. Both gender stereotypes and self/ideal self descriptions show similarities across countries as well as differences. In both studies, the cultural nature of the differences becomes evident only when the country results are scored for their affective meaning, on the dimensions of favorability, strength, and activity. Affective meaning differences tended to be larger in socioeconomically less developed countries; they were also positively correlated with G. Hofstede's Power Distance measure. Differences in gender stereotypes and in self-descriptions were unrelated to Hofstede's Masculinity scores, except that in countries high on Masculinity, both gender stereotypes and men's and women's self-descriptions were less differentiated than in countries lower on Masculinity.
