My niece and nephew

After reading the different theoretical approaches to gender development I thought of my own twin niece and nephew who are only four years old. My sister has never allowed for toy guns or toy weapons of any kind. However, my nephew Adrian as been fascinated with all types of play weapons regardless of her attempts. Ever since he was able to walk he would wonder around the yard collecting sticks to act as swords and guns. My niece on the other hand was completely disinterested in this sort of play. She enjoys setting up her doll house and play cooking while he searches for something to "blast" her with. Of course these preferences could not strictly be attributed to gender, but I've noticed many individuals claim that is the case. I've heard family members claim it is sheer biology, as in biological theories of gender, that he be more aggressive and she more sensitive. I've heard that he naturally enjoys sports and playing fireman, policeman, or soldier due to his gender while she plays mommy or chef. However, I find that psychodynamic theories and social learning theory can be applicable as well. They have learned in relation to each other and the world around them which has contributed to their gender identities. They role modeled after mom and dad, meanwhile always maintaining their own roles as the girl or boy, sister or brother, in counterpoint to each other. Also, they've been exposed to much learning in the media, story books, television and their experiences at preschool. I feel that simply stating their behavior is biological and "natural" ignores the myriad of interpersonal and cultural components to gender development.
