The invention provides an attention ability testing device and an attention ability testing method. In the attention ability testing method, in a state of displaying a center figure (32) in a center area (26) of a display area (24) of a display (12), at least one of a center topic for changing the center figure (32) at a predetermined speed in an unstable manner and a peripheral topic for displaying a peripheral figure (34) in a peripheral area (28) of the display area (24) is randomly generated. The time from the occurrence of the central subject or the peripheral subject to the reception of a predetermined operation by the subject who has recognized the occurrence is measured as a reaction time, and the attention ability of the subject is evaluated on the basis of the reaction time.
