Psychological differences between girls and boys which influence socialization of the young in their perceived gender roles are becoming highly important. The aim of the present research is to study these differences within the conceptual framework of BEM Gender Index. The
data was gathered through questionnaires completed by a sample group of over 500 high school students. The research findings demonstrate significant differences among girls and boys in such a way that gender beliefs among boys in comparison to girls were more non-stereotyped. If born again, girls
wished more than boys to have a different sex. This issue is an indication of girls being less content than boys about their sex. Considering that girls with active and social characteristics and behaviors, and boys with emotional characteristics and behavior were more frequently criticized, it seems gender
stereotyping is a prevailing practice in the society and getting away from it is considered an abnormality.
