Hi Malkavian,
The short answer is yes, you can certainly train yourself to be
ambidextrous. The task of motor function is allocated to a specific area
of the brain called the motor cortex. Since our brains are divided down
the middle we essentially have two of these areas. The tricky thing is
that the motor cortex on the right side of the brain controls the left
side of the body, and vica versa for the left. Now, when we walk, we use
both legs equally well, or when we raise our hands both the right and left
can do this task equally. The difference becomes apparant when we use
fine motor skills, like writing, or throwing a ball. The reason we can
throw or write better with one hand is because we trained ourselves to do
it that way. Now, there is also a little bit of dominance going on there
too. You can start teaching a child to throw a baseball with his right
hand, but he may feel more comfortable doing it with his left. Why, who
knows? But there is something hardwired in most people that makes us
prefer one hand or leg over the other. We can train ourselves to perform
any task with the other hand though. For instance, I play the guitar and
have to use my left hand to fret the strings while my right hand either
plucks or strums. I have a left handed friend who has a lef handed guitar
and I can't play that worth anything because I have trained my hands for a
right handed guitar. But I am able to figure out where to put my fingers,
and with time I am sure that I could become adept at playing the other
way. As for how long it would take, that is up to each person
individually. Everyone has different speeds of learning a physical task
which also depends upon what that task is and the amount of practice. The
most important thing is that it is possible with lots of hard work. Good
luck,
Mark
