1. A method to evaluate functional impairment in a brain of a subject, said method comprising the steps of:

  • performing a spatial distractor tasks test, said spatial distractor tasks test assessing the combination of visual motion and visual form, said spatial distractor task test comprising the following steps executed on a processor;

    presenting at least one scene to said subject on a display, said scene comprising a plurality of elements and a background;

    modulating the saliency of a predetermined section of said scene;

    receiving feedback from said subject, said feedback associated with input device;

    superimposing at least one additional cue onto said scene, said additional cue associated with at least one distractor;

    generating a shift in attention of said subject from said predetermined section to said distractor;

    receiving refined feedback from said subject via at least one input device;

    quantitatively refining said refined feedback relative to said scene;

    adjusting the motion associated with said scene relative to accuracy of said quantitatively refined feedback, said adjusted motion associated with a predetermined target;

    calculating a critical threshold parameter for said subject;

    recording said critical threshold parameter onto a tangible computer readable medium; and

    using said critical threshold parameter in assessing evaluating or determining at least one functional impairment in a brain of said subject.
