Spatial ability is located in both brain hemispheres for women but does not
have a specific measurable location as it does in males.
Only about ten percent of women have spatial abilities that are dynamic
as those of the best males. Around 90 percent of women have limited
spatial ability. Full stop.
To some people, this research may appear sexist, because 'we' have
strengths and abilities at which males and females excel and the pursuits
and occupations in which biology has given each clear advantages over
the other despite legislation to he contrary.
Spatial ability means being able to picture in one's mind the shape of
things, their dimensions, coordinates, proportions, movement, and
geography. It also involves the ability to imagine an object being rotated
in space, navigating around an obstacle course, and seeing things from
a three dimensional perspective. Its purpose is to work out the movement
of a target and know how to hit it.
Iowa State University professor of psychology Dr. Camilla Benbow analyzed the brain scans of more than a million boys and girls to study their spatial ability and reported that the differences between the sexes were already striking at the age of four. She found that while girls were excellent at seeing two dimensions in the brain, boys had the ability to see a third dimension , giving depth. On three
dimensional video tests, boys outstripped girls
in spatial ability by a ratio of four to one and the lowest scoring boys
often outclassed the best girls. For a total picture see brain scan studies from the Institute of Psychiatry, London.
Women simply do not have good spatial skills because they evolved chasing little else besides men...what's the problem....
Why women can't read maps is NOT the same as why men refuse directions..
"If men didn't design maps that way, we wouldn't have to turn them upside down,"
many women complain, even in basic Map Reading in the military.
