A method and system of organizing salient, aversive, and neutral stimuli in a visual display, deliberately separated by space and/or time, to better reveal attractors and aversions for a test subject observing the display, whose reactions are tracked using eye and gaze tracking, as well as other optional body parameters, all captured as data. The data is analyzed using rules and algorithms to characterize or diagnose the subject based on single test results, or comparison to prior test results, and comparisons to norms. The method and system may be employed on stand-alone, off-the-shelf electronic devices, including smartphones, tablets, laptops, and desktops, as well as on higher-end computers systems, specialized equipment, and cloud-based set-ups, allowing mobile or setting-based usage. Optional sensor inputs may be utilized for the optional inputs described above.
