An autism diagnosis support method and system, and autism diagnosis support device capable of providing support to early detection and early definite diagnosis especially to autism of infants, on the basis of objective evaluation, are provided by using a conventionally proposed 'eye-gaze detection technique'. For example, a method for supporting autism diagnosis for a subject, uses an eye-gaze detecting unit (A) at least including a camera portion capturing an image of an eye of the subject, or an electrode portion to be mounted on a head of the subj ect and detecting a movement of the eye, or a display portion to be disposed at a position in an eye gaze direction of the subject. The method includes: displaying, on a screen of the display portion, a combination image for sequentially displaying at least two images including a predetermined human image (I) and a predetermined non-human image (II); and evaluating an eye-gaze position of the subj ect by detecting eye-gaze position information on the subject looking at the combination image in use of the eye-gaze detecting unit, then inputting the eye-gaze position information on the subject in an eye-gaze position information storing portion, and comparing, based on an eye-gaze position evaluation algorithm, the eye-gaze position information on the subject with eye-gaze position information on an individual with autism and/or a typically developing individual.
