Principal Component Analysis Studies During Emotion Transformation

Using Principal Component Analysis( PCA) method,some emotion transformations are studied by EEG data. With the emotion transformation,most of right-handed woman subjects who have arousal e motion have a higher contribution rate of the first principal component,and a lower contribution rate of the second principal component,while the right-handed man do not a clear relations. By studying the contribution rate of each electrode in the first principal component,EEG load range for men is closer to the front of the head when the emotion transformation. So PCA can be used to distinguish right-handed woman emotion changes,while the right-handed man needs more research.
