1. A method for diagnosing dyslexia by measuring contrast sensitivity for motion discrimination of a subject having a visual cortical movement system, said method comprising the steps of:

  • (a) displaying a background with a contrast and a spatial frequency;

    (b) displaying a test window within said background, said test window including a test pattern with a contrast and a spatial frequency, said test pattern replacing said background;

    said contrasts being within a range which stimulates the visual cortical movement system of the subject;

    said spatial frequencies being within a range which stimulates the visual cortical movement system of the subject;

    (c) moving said test pattern within said test window in either a first direction or a second direction;

    (d) receiving a signal from the subject indicative of either said first direction or said second direction;

    (e) modifying at least one of said contrasts or said spatial frequencies in response to said signal;

    (f) repeating steps (a) through (e); and

    (g) using the signals from the subject as criteria for forming a diagnosis of dyslexia.
