He got interested in dyslexia from seeing many children with damage to the part of the visual system that senses movement, whose first inkling of trouble was that the world began swinging round crazily when they tried to read. With Sue Fowler, a brilliant orthoptist, who’d noticed the same kinds of symptoms in dyslexic children, he put forward the theory that their visual motion system may be impaired – the ‘magnocellular’ theory of dyslexia. Although the idea is still controversial, more and more people are accepting it now.
