Document Summary
They believed that structural changes lead to behavioural changes in humans. Hormones affect development of the cns not only in humans but other species too. Up until 23 -24 years old the brain and body are still plastic- we are still learning. You can eliminate the gonads and take away hormones and look at their development. We can see areas in the brain that are associated with brain development. Boys prefer toys like trucks where girls like dolls- gender development. The question slide: one way to separate human culture/society from physiological development is by looking at other species (they don"t have our culture, but they have the same hormones and there are gender differences) 98 percent the same genes compared to other species to humans. Female monkeys like dolls like humans and males like truck. Monkeys show the same type of behaviour that humans display so it"s probably physiological in nature.
