Background:  The tendency to avoid negative emotions may occur in any psychological treatment process. In this regard, Robert Leahy reviewed this topic by presenting the model of emotional schemas. He believes that excitement is some sort of information. Excitements arise from the parallel processing of various information and most of them occur outside the scope of consciousness.
