Yesterday Kelly and I were brainstorming ideas for future posts. We peppered PJ, Kelly’s son, with questions because he is leaning towards being left hand dominant. We asked PJ if he would be our guinea pig. He, in the middle of playing a game on the iPad, without missing a beat answered with a wry smile, “Well, I like being a human.” He’s seven, quick as a whip. PJ has previously participated in our project and understands it’s importance to us. PJ explained that he used his left hand most of the time to touch the iPad to play his game but could use both hands if required. He also uses his left hand for moving his miniature Army men and Legos.
Studies show that the corpus callosum, the area that connects the right and left hemispheres of the brain, is larger in left handed people because they use both sides of the brain to process. Whereas right-handed people process with only the left hemisphere of the brain. Left handers outperform righties in playing video games and other tasks that involve handling a lot of information and stimuli. PJ could be an ace fighter pilot someday.
Sandy: My hope from using my left hand regularly for a year is to use more of my brain so both sides have equal amounts of stimulation. Maybe then I will be able to play video games without getting motion sickness.
Sandy’s year long journey – going from being a right-hander to left-hander, and Kelly’s parallel trip as a left-hander doing things as a right-hander.
