Visual perception
Lefties may have a more balanced view of their bodies. When asked to visualize space, right-handers tend to be more sensitive to their right-side and perceive a puny "T. rex"-like left arm and a larger, longer and stronger right arm, Linkenauger said. Lefties have no such bias, which may come from a lifetime of having to navigate in a right-handed world, Linkenauger said.
