Abstract
A method is presented to address quantitative assessment of spatial distractor tasks in a subject, where the method comprises the steps of: (1) presenting at least one scene to a subject on a display, said scene comprising a plurality of elements and a background; (2) modulating the saliency of a predetermined section of the scene; (3) receiving feedback from the subject; (4) superimposing an additional cue onto the scene; (5) generating a shift in attention of the subject; (6) receiving refined feedback from the subject; (7) quantitatively refining the refined feedback; (8) adjusting the motion associated with the scene relative to accuracy of the refined feedback; and (9) calculating a critical threshold parameter for the subject; and (10) recording the critical threshold parameter onto a tangible computer readable medium. An apparatus for quantitative assessment of spatial distractor tasks 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 spatial distractor tasks by psychophysical responses is generated on a tangible computer readable medium.
