Abstract
A physiological state determination device determines a predetermined physiological state of a subject. The physiological state determination device includes a brain function activation information detection unit, a face change information acquisition unit, and a physiological state determination unit. The brain function activation information detection unit detects brain function activation information corresponding to a physiological state. The face change information acquisition unit acquires face change information indicating a time-series change in face data of a subject. The physiological state determination unit determines the predetermined physiological state of the subject based on the brain function activation information and the face change information.
