Is there any solid research that shows a left/right mixed dominance is responsible for some physical uncoordination, dyslexia, handwriting problems, etc.?
GS8 writes left handed but does most large muscle activities right handed. His handwriting is a bit sloppy but can be very neat when he tries. He draws very well. Something I've noticed about his letter writing, he starts many letters from the right and draws to the left. I think it's because no one taught him how to make letters. He saw them, and wrote them. And since he's a lefty, it would be more natural to make a letter from the right to the left. He still reverses some letters, too. Is this unusual for 8.5?
