Many people think that the hallmark of dyslexia is letter reversals, writing letters or words upside or backwards. Although many people with dyslexia have this problem, not all of them do. It is by no means the hallmark of dyslexia that many people believe it is. ALL children have trouble with letter reversals at a young age. Dyslexic children may do it more frequently and until older ages. Some will always struggle. However, the problem has more to do with directionality issues and the special way that the brains of dyslexics work. It has nothing to do with eyesight!
Research has shown that a person with dyslexia will generally have a larger right brain hemisphere than a person without dyslexia. Dyslexics tend to be strong right-brain thinkers. This is part of why they have reading problems – reading occurs in the left hemisphere. The right-brain is where we process a lot of creative and visual-spatial thinking.
When a child with dyslexia sees a letter, he often interprets it in three dimensions. Thus, a stick and a ball are always a stick and a ball, no matter how you look at them.
And a letter S is just a snake.
It is easy to see how any young child can reverse letters, but easier to see how a child with particularly strong visual-spatial skills might not be able to understand why it matters which way you put the “objects” that make up a letter.
But have no fear, it is usually fairly easy to teach them some tricks to keep those letters straight!
