1. A method of assessing, diagnosing, or assessing and diagnosing a neurobehavioural disorder in a subject, comprising:

  • using a processor-based computational model to select one or more feature in a visual scene and generate a spatial map having first map values that are predictive of eye movement end points of a hypothetical observer relative to the one or more feature;

    recording the subject'"'"'s eye movements while the subject freely observes the visual scene; and

    generating second map values that correspond to the subject'"'"'s eye movement endpoints that do not rely on the subject performing a task;

    quantifying a difference between the second map values and a set of map values selected randomly from the first map values;

    wherein the difference is indicative of a neurobehavioural disorder in the subject.
