摘要： A mental work load detector arranged to sense the electroencephalogram of a person and estimate a mental work load on the perceptual-motor system and a mental work load on the perceptual-central processing system separately from each other includes a electroencephalogram sensor arranged to sense the electroencephalogram of a rider, an eye fixation-related potential detector arranged to detect an eye fixation-related potential by analyzing the electroencephalogram and to detect a lambda response, an event-related potential measuring device arranged to measure an event-related potential in response to a sound from a speaker and to detect auditory p300, a lambda response comparator arranged to determine whether the lambda response has decreased, an auditory p300 comparator arranged to determine whether the auditory p300 has decreased, and a mental work load determiner arranged to determine that the mental work load on the perceptual-central processing system has increased if the lambda reaction and the auditory p300 has decreased and that the mental work load on the perceptual-central processing system has increased if the auditory p300 has decreased but the lambda response has not decreased.

摘要： Disclosed herein is a biofeedback device which separately extracts the .alpha. wave component and the muscle component included in the brain wave and, therefore, permits the user thereof through auditory perception of associated audio frequency sounds to recognize accurately the appearance in the brain wave of the .alpha. wave component or muscle component on the basis of the principle that exclusive perception of the sound associated with the .alpha. wave component indicates relaxation of the subject's mental state, exclusive perception of the sounds associated with the muscle component indicates tension of the subject's mental state or cephalic state and simultaneous perception of the sounds associated with both components indicates occurrence of a phenomenon having nothing to do with the responses for feedback training.
