My wife overheard me talking today about this to a client in the store. Momma is a Speech Path. so she cruises home, and googles up this:
Not sure what here resource is:
In most (97%) right-handed people language is controlled by the left hemisphere. Left-handers have a more even distribution of language in both hemispheres. In 19% this is concentrated in the left hemisphere, and in 68% it is concentrated in the right hemisphere, the remainder have language processing in both hemispheres.
So if I'm Left-Handed, Does This Mean My Right Brain is Dominant?
No, hand dominance is not directly related to brain dominance. And, remember, just like you don't do everything with only the one hand, so your brain doesn't do everything with one side, although there is generally a preference. However, a significant number of artists have been and are left-handed, more than would be suggested by the one-in-ten occurence of left-handedness in the population. While those who are left handed do exhibit a greater propencity for right-brain dominance, being right handed does not preclude your right brain from dominanting.
But I would be derelict if I did not dial the story into the realm of engineers. Like engineering, woodworking is a left brain activity with a little right brain thrown in for creativity. What's more, Norm studied mechanical engineering and is keenly aware engineers are a big group among his viewers. Just before I interviewed him, he was having a discussion with a tool supplier about how finicky and precise retired automotive engineers are as tool buyers.
What a great wife! She tries to keep my obsessive compulsive nature in check.
