Hi Richard:

I recently trained myself to use the computer mouse with my left hand.

It took about one month to be able to proficiently use the mouse with my left hand to browse the web, or type.

It took about two months to use the mouse left-handed to work with complex graphics programs.

I am now totally ambidextrous when using the mouse. It feels comfortable and easy, too.

I notice that many very intelligent people, including my overachieving husband, a high-level executive, who try to do this, give up fairly quickly....frustration, perhaps....Or, lack of patience.

I also play the guitar, though, so perhaps that made it a bit easier, for me.

From my perspective, learning to play the guitar simply made it less difficult for me to believe that with time using the left hand, in certain applications, can become second nature.

As your article appears to suggest, I do believe that there is an obvious positive effect on cognitive functions after training the brain to use the left hand for complex activities.

It seems that I make connections more easily when problem solving, and summon more creative ideas more easily.

IME, based solely on my own personal observations, Switching back and forth between my left and right hand during the problem solving session or when needing to be creative, seems to amplify whole brain thinking, in a positive way.

Dear Shaun,

Thank you so much for sharing your observations with us.

My own experience, as well as those of my students and a careful analysis of the neurological iterature all confirm what you have found out for yourself.

I am quite certain that retraining your brain like this does indeed enable you to mobilize more of your cognitive reserves when you need them.

Kind regards,

Has there been any work done to explore the reasons why dominant handed people sometimes utilize the opposite(?) handedness when they do two handed activities, with special interest in golf? In reviewing your left handed sportspeople list for golfers, it is clear that some lh folks were converted to rh, Hogan, Jones maybe Miller and Price while Michelson and Weir are like me, rh but playing lh and unlike me are pros, tournament winners, Masters winners. My theory for years has been that that 2 handed activities have been misnamed for centuries. I write and throw and do almost every other one handed activity with my right hand. However, with all two handed activities, it is best when my left hand is low on the implement or tool or bat or club - the supposed left handed attitude. Consider, I set up with my right side towards the target, I set up on the right side of the ball, I turn into impact towards my right side, I work my right arm to the ball first, I transfer my weight from left to right thru the shots, if I draw a shot - it moves to the right....but I am supposedly playing left handed!? Convinced that this is, in fact, right handed. In my family, my right handed wife - plays right handed by popular convention, our older son is totally left handed one handed but plays right handed (or is he playing left handed?), our younger son is rh but plays left ( or is it right handed, like me?). In interviewing hundreds of lh(?) playing golfers over decades, I have found perhaps 6 that were truely left handed, one handed. I was tested with a gripper instrument by one of my instructors a few years ago as I bugged her with handedness questions. She claimed that the gripper clearly indicated that I am in fact left handed so it made perfect sense to her that I played left handed. Don't believe the testing, ie, perhaps I don't want to accept that I may be left handed. So....confusion reigns and does it really matter
