In the past ten years, many scientists have studied the differences between men and women and they all got the same conclusion: men and women are different because their brains are different and this makes men and women see the world in different ways. Boys, for example, are generally better than girls at mathematical ideas involving objects and their relationships. Boys also are generally faster in response than girls of hand and eye movements in ball games. Girls, on the other hand, generally start speaking earlier and can see better in the dark and are better at learning foreign language than boys. What makes men and women better at one thing or another? The answer is the brain. The brain has two sides. The nerves on the left side are for mathematics, speech, reading, etc. , while those on the right side are for artistic creation and other senses. In men and women, different areas in each side of the brain develop differently. In boys, for example, it is the area for mathematics and in girls it is the area for language learning that develops better. Another interesting difference is that the two sides of a man's brain are interconnected by a smaller number of nerves than in the case of a woman, so the flow of information between them is more limited. Scientists think this affects some of our abilities. For a long time people believe that ______.
