A child perceives things and learns with a sense of touch. Early intellectual growth arises first and foremost out of the child's physical interactions with objects in his environment.
Children do not know to discriminate in objects, even in genders. As they grow, the child develops a sense of gender identity, thinks of himself or herself as a boy or a girl, and begins to relate to others differently according to their gender. They learn how to dress and decide what to wear. For example, a 5-year-old boy will not feel comfortable if he is dressed in frock or any other feminine dress.
Every shrink should read Intro to Objectivist Epistemology by Ayn Rand (http://www.amazon.com/Introduction-Objectivist-Epistemology-Expanded-Second/dp/0452010306/ref=sr_1_19/104-4077040-3689513?ie=UTF8&s=books&qid=1176735232&sr=1-19), and then every shrink should also read by environmental psychologist J.J. Gibson (http://en.wikipedia.org/wiki/J._J._Gibson) called The Ecological Approach to Visual Perception (http://www.amazon.com/ECOLOGICAL-APPROACH-GIBSON/dp/0898599598/ref=pd_bbs_sr_1/104-4077040-3689513?ie=UTF8&s=books&qid=1176735095&sr=8-1). Especially since both predate much of the article's discussion on human development and learning. :3
