1. An evaluation apparatus comprising:
a display;
a gaze point detection unit configured to detect a position of a gaze point of a subject;
a display controller configured to display, on the display, an evaluation image including a main target image, multiple sub target images, and an instruction information for instructing the subject to gaze at the main target image;
a region setting unit configured to set multiple determination regions for the multiple sub target images respectively;
a determination unit configured to determine whether the gaze point is present in each of the multiple determination regions based on the detected position of the gaze point;
an arithmetic unit configured to measure an arrival time from a predetermined time to a first arrival time of the gaze point at each of the multiple determination regions based on a determination result of the determination unit; and
an evaluation unit configured to evaluate that probability that the subject has attention deficit hyperactivity disorder is classified as high when an average value or a total value of all of the arrival times for all of the multiple determination regions is smaller than a predetermined threshold value as compared with the probability when the average value or the total value of all of the arrival times for all of the multiple determination regions is at or larger than the predetermined threshold value.
