In the first supernatural tradition, also called the demonological method, abnormal behaviors are attributed to agents outside human bodies. According to this model, abnormal behaviors are caused by demons , spirits , or the influences of moon , planets , and stars . During the Stone Age, trepanning was performed on those who had mental illness to literally cut the evil spirits out of the victim's head. Conversely, Ancient Chinese , Ancient Egyptians , and Hebrews , believed that these were evil demons or spirits and advocated exorcism . By the time of the Greeks and Romans , mental illnesses were thought to be caused by an imbalance of the four humors , leading to draining of fluids from the brain . During the Medieval period, many Europeans believed that the power of witches , demons , and spirits caused abnormal behaviors. People with psychological disorders were thought to be possessed by evil spirits that had to be exercised through religious rituals. If exorcism failed, some authorities advocated steps such as confinement, beating, and other types of torture to make the body uninhabitable by witches , demons , and spirits. The belief that witches, demons, and spirits are responsible for the abnormal behavior continued into the 15th century.  Swiss alchemist, astrologer, and physician Paracelsus (1493–1541), on the other hand, rejected the idea that abnormal behaviors were caused by witches , demons , and spirits and suggested that people's mind and behaviors were influenced by the movements of the moon and stars. 
UPDATE: This Abnormal Psychology course is uses the diagnostic criteria presented in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) published by the American Psychiatric Association in 2000. In May 2013, the APA released a new edition, the DSM-5 which has significantly impacted the multiaxial system presented in this series and has significantly impacted some of the diagnostic categories and diagnoses. An updated podcast series based on the new DSM-5 will be available Spring 2015. This course is intended to provide a survey of theories and etiology of abnormal behavior and its social significance; description of symptoms; consideration of techniques of therapy and theories of prevention. The material in this series related to mental health diagnoses is based on the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision which was published in 2000. The podcasts presented in this series will include live class recordings of lecture presentations and additional pre-recorded segments that focus on frequently asked questions and concepts that often provide a challenge for many students. These recordings may also be supplemented by PDF files or handouts designed to further enhance the student’s understanding of the field of abnormal psychology. These materials are intended to supplement the traditional classroom approach of my courses and to enhance the student’s learning experience. Target audience should include current students and others who wish to know more about the topic areas. The materials will not be textbook specific so that they will be useful to others. For HACC students, the purpose is to allow them an opportunity to review or catch up on lectures/class periods that they may have missed or misunderstood. For other learners outside of HACC, the purpose is to supply another resource for their learning that is both entertaining and educational. The course was originally recorded during the Fall Semester 2010 with some updates as necessary. Please send any suggestions/feedback to drbailey@. I hope you enjoy listening and thanks for exploring the world of abnormal psychology with me.
