This brain activity feature amount extraction method includes acquiring a combination of a plurality of data items in order of higher effectiveness for discriminating whether a subject is a healthy person or a non-healthy person, among the plurality of data items, on the basis of the index value serving as the index indicating effectiveness or non-effectiveness for discriminating the group of healthy persons and the group of non-healthy persons from each other, and displaying the acquired combination of the plurality of data items in order of higher effectiveness.

A tactile stimulus presentation device includes a stage, a contact member, a drive mechanism, an information setting part, and a control part. The stage includes an opening and an arrangement surface, the arrangement surface on which a body part of a subject is arranged thereon so as to close the opening. The contact member is for giving a tactile stimulus to the subject by being in contact with the body part of the subject arranged on the arrangement surface of the stage through the opening. The drive mechanism is a mechanism for holding the contact member and moving the contact member in a direction substantially parallel to the arrangement surface and in a direction substantially perpendicular to the arrangement surface. The information setting part is configured to set information to be presented by gibing tactile stimulation to the subject by tactile stimulation. The control part is configured to control the drive mechanism to present the information set by the information setting part by giving tactile stimulation to the body part of the subject arranged in abutment on the arrangement surface.
