The present invention to provide a method for determining positive and negative emotional states by using a relative power in a subband of a specific frequency band increases or decreases in the course of time. In order to realize the above object, the present invention determines positive and negative emotional states by using a relative power in a subband of a specific frequency band increases or decreases with the lapse of time. The present invention performs a Fourier transform for a unit time not an entire response time regarding a stimulus, and can be used in real time by using a time-frequency analysis method continuously executed with the lapse of time.
