Importance of imagery in maintenance of feedback-assisted relaxation over extinction trials

Two groups of 16 female subjects undergoing frontalis EMG feedback training were identified according to whether they used imagery or passive concentration to achieve relaxation. The ability of these 2 groups to maintain relaxation during extinction sessions 2 and 7 days after termination of training was then investigated. Although both groups were equally successful in relaxing the frontalis during training, the group using imagery was significantly more successful in achieving relaxation during extinction sessions.
