EEG device	14-channel Emotiv EPOC
Experimental protocol	Psychotherapist conducts the HAM-A test for each participant and computes a total score that measures a subject’s anxiety severity. For each situation, the psychotherapist recites each situation for 15 s then the subject recalls and imagines for another 15 s. Then the subject is asked to rate his/her feelings during stimulation using SAM for 30 s. After the 6-min trials, the psychotherapist re-evaluated some elements of the HAM-A test to update the subject’s anxiety level
