Testing Predictions from the Hunter-Gatherer Hypothesis - 1: Sex Differences in the Motor Control of Hand and Arm
J. Whittaker: HGH = sex differences in task performance arose from natural selection favoring hunting-related skills in men and gathering related skills in women. Men should do better at throwing (arm muscles) and visual input from afar, women better at visual input from close, and fine hand manipulations. Test with computer cursor tracking test using hand or arm alone, and ball throwing and peg-board tests and find as predicted males do better with throwing and arms, females with hands and pegs. These tests correlate with non-motor word association test favoring females, and mental rotation test favoring males.
