Southpaws Have a Different View

…The results, reported in Psychological Science, reveal some differences in the way left- and right-handed people perceive their arms. Left-handed volunteers judged both of their arms to be the same length, but right-handed participants underestimated the length of their left arm—they consistently perceived their right arms as being longer.

In addition, right-handed volunteers thought their right hands were larger than their left, when in fact, they were both the same size. When guessing how far they could reach with their arms, left-handed volunteers estimated they could reach equally far with both arms while right-handed volunteers predicted they could reach farther with their right arm.

These findings suggest that body maps in our brain may influence how we perceive our physical bodies—for example, if there is a lot of brain area associated with our right arm, we will view it being as longer compared to our left arm.
