Abstract
A method of making a judgment on emotional positivist or negativity of a person, comprises the steps of obtaining asymmetry ratio between the brain waves of the left and right cerebral hemisphere measured in a given unit time by means of electrodes attached to the left and right side of the scalp, calculating asymmetry ratio versus time at each frequency of the measured brain waves if the time taken for measuring the brain waves exceeds a given time interval, calculating an increase and a decrease of the asymmetry ratio of the previous step with time, and entering the increase and decrease into an artificial neural network to make a judgment on the emotional positivity or negativity.
