Reading is one problem facing children having perceptual lags in their development. Some children may reveal clinical evidence of brain injury while others merely show uneven developmental patterns on psychological tests. These children cannot respond to the usual methods of instruction presented during their early school experiences. The regular educational materials and methods are inappropriate for them and must be adapted to meet more primitive learning needs.
