EMG Induced from The Muscles near The Eyeball

Abstract

Up to this time a psycho-physiological indication corresponding to a subject's cognition has been sought for. From the object which the subject is watching and the speech and behavior in which he express his feeling as the result we have drawn deduction on his cognition, and pride to follow the relation between the cognition and the psycho-physiological response. At present, in order to know the object the subject is watching, the record of the shifting visual recognition by the method of corneal reflection is in use. But this method only shows which way the eyes are looking, and it is impossible for us to find out whether he is in visual recognition or not. By our experiment, examining by the indication of EMG the tension of muscles near the eyeballs which is supposed to be caused only when he is watching some- thing, we tried to find out if there is such recognition as above mentioned. The average ampliture per second of EMG at the time of visual recognition indicated a smaller value than at the time of unvisual recognition. From the fact, however, that the amplitude at the time of unvisual recognition for the two difficult themes indicated a large value, the examination of the theme and the amplitude of EMG, etc., has come to needed.
