Reading disorders are diagnosed and remediated in a subject by respectively measuring and improving contrast sensitivity for motion discrimination of the subject. A background (130) is displayed on a monitor (104) with a contrast and a spatial frequency. A test window (134) is superimposed over the background (130) and includes a test pattern (132) with a contrast and a spatial frequency. The contrasts and the spatial frequencies are within respective ranges which simulate the visual cortical movement system of the subject. The test pattern (132) is then moved within the test window (134). The subject provides a signal indicative of the direction of the subject believes the test pattern (132) moved. In response to this signal, the contrast of the test pattern (132), the spatial frequency of the background (130), or the spatial frequency of the test pattern (132) is modified, either by increasin g or decreasing its respective value. This process is then repeated a number of times, cycling through predetermined combinations of test patter ns (132) and backgrounds (130). Contrast sensitivity may be measured to determine whether a child is dyslexic. Repeated stimulation by t he methods and apparatus of the invention improves contrast sensitivity, thereby remediating dyslexia and improving reading ability.</SD OAB>
