about people. They are mainly social tools. Visual and spatial abilities are
good for imagining and manipulating objects and for communicating information about
them. Are these talents programmed into their brains? In some of the newest and
most controversial research in neurophysiology, it has been suggested that when
it comes to the brain, males are specialists while women are generalists.
