A method is presented to address quantitative assessment of word recognition sensitivity of a subject, where the method comprises the steps of: (1) presenting at least one scene to a subject on a display, the scene comprising a plurality of letters and a background; (2) distorting the scene; (3) moving plurality of letters relative to the scene, the movement being tracked by the subject via at least one input device; (4) receiving feedback from the subject via the input device; (5) quantitatively refining the received feedback; (6) modulating the movement of plurality of letters relative to accuracy of the received feedback; (7) calculating a critical threshold parameter; and (8) recording a critical threshold parameter onto a tangible computer readable medium. An apparatus for quantitative assessment of word recognition sensitivity of a subject comprising a display device, an input device, a control device, and a tangible computer readable medium. In its simplest sense, quantitative assessment profile of word recognition sensitivity by psychophysical responses is generated on a tangible computer readable medium.
