  1. Psychological Therapies

    There are several major kinds of therapies used. The first therapy is called behavior therapies. Behavior therapies are action therapies based on the principles of classical conditioning and aimed at changing disordered behavior without the concern for the original causes of such behavior. This therapy is based on the teachings of classical conditioning and operant conditioning. Behavioral therapists work to change problematic behaviors that have been trained through years of reinforcement. A good example of behavioral therapy would be a therapist working with a client to overcome a fear of heights.

    The researchers took blood samples before the monks ascended the mountain. The monks were exposed to the harsh autumn weather, did not speak or consume water or food. After approximately 48 hours, the monks began to hallucinate claiming that they saw ancient ancestors or they felt their presence. Immediately, blood tests were taken and stated that serotonin levels increased. They concluded that sensory deprivation triggered the release of serotonin.

Page 19 ________________ INTRODUCTION The reliability of eyewitness testimony has often been questioned in cases of crime and violence but yet the judicial system seems to ignore its flaws. Numerous psychologists have carried out experiments and studies regarding this issue. Eyewitness testimony has a large psychological background that judges, lawyers and the jury seem to ignore.
