So where do these differences between male and female behaviour come from? Although it is ture that culture and upbringing play an important role, many scientists now believe that the answer also lies in the amount of the male and female hormones in the mother's body before a child's birth. Research has shown that this balance of hormones leads to three different types of brain: type E, type S and type B . Peeple who are born with a type S or male brain are generally interested in system: constructing and organising things and working out how things work. They tend to be good at working out where they are, from maps, making things from plans or collecting things. Others have a type E or female brain which means they are good at understanding other people's emotions and treating people with care because they are sensitive themselves. Others are born with characteristics of both these male and female brain - this is called the type B or balanced brain.
