Traditional talk therapy focuses on the content of the story. Experiential therapy focuses on helping people get in touch with their core emotions. This modality can be especially effective for those who have experienced little change after long-term psychotherapy.
Although both types of therapy help you to recognize the thoughts in your head, experiential therapy aims to help you recognize the feelings associated with those thoughts. In order to heal the mind we need to experience the emotions brought on by the troubles we've faced.
