no. if you are right handed this is the normal,
your right brain controls less logical tasks, where verbalization doesnt occur. dont speak to anyone sketching while they are drawing as they cant do both.
your left side controls motor function, speaking, rationalization.
left handed people use both sides of the brain to do normal left side controls, and if your dysbraxic, the wiring is even more complex.
