Method and system for quantitative assessment of spatial distractor tasks

A non-transitory computer readable medium, said medium containing instructions executable by a processer to evaluate functional impairment in a brain of a subject, the steps comprising:

• 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:
• 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;
• and
• outputting said critical threshold parameter, said critical threshold parameter used in assessing, evaluating, or determining at least one functional impairment in a brain of said subject.
