I am currently doing some research about human emotion based on EEG classification.
I do an experiment in that I show subject a picture about 3 state of emotion and record their EEG signal. I split my experiment into 3 set, each set I change record order (for example: Set 1: emotion 1, 2 ,3 ; Set 2: emotion 2, 3, 1 and Set 3: emotion 3,1,2).
I have a question that at different record time (or at different set) does the EEG signal perform on same task have the same characteristics with order set.?
I have this question because I hear that people always change state of mind at different time.
Thank you very much.
