The effect can be to make them feel that they must be stupid. This is why it is important for dyslexic children to receive as much praise, credits, certificates, gold stars, etc. as the other children. To complete a piece of written work in class is twice as hard as for a non-dyslexic child. It is also important for a dyslexic child to have art, crafts, physical education and sports during their week in school, as these are the only areas in which they may excel and experience a feeling of satisfaction in learning. On the contrary, given proper support, dyslexic students are perfectly able to go on to achieve good degrees at university and pursue successful careers.
People use both sides of their brains but have a bias towards one or the other.
Traditional academia is very left-brained with an emphasis on words, details and categorizing. The right side of the brain focuses on non-verbal and intuitive ways of working. If children have difficulty learning to tell the time, following instructions which involve left and right, learning the alphabet or anything which has to be remembered in sequence, they may well be right-brained. They are likely to be artistic and creative but disorganized at times. It is suggested that many learners with dyslexia have right-brained dominance.
