| Abstract | Unintentional movement "overflow" between the hands or "mirror movements" are common in young children, but are generally regarded as indicative of developmental delay in older children. This study was designed to investigate mirror movements in a sample of 23 very poor readers, ages 11-13, with learning disabilities, and in a control group of 48 normal readers, matched for age, sex, and handedness. Five rapid repetitive movements and eight slow finger-displacement movements were studied, and overflow to the opposite hand was quantified. A significant interaction of reading ability with type of movement was observed, with reading-impaired children making more mirror movements during slow finger displacements (but not during rapid repetitive movements) than normal readers. Reading-impaired children showed greater left-hand overflow and normal control children showed greater right-hand overflow overall. The two groups were differentiated by the pattern of overflow rather than the overall amount. It is concluded that dyslexic children were more likely than normal children to co-activate the left hemisphere whenever the left hand was used, and dyslexic children activated both hemispheres in circumstances where normal children did not.
