Describe positron emission tomography (PET) and explain how it can be useful in the study of brain functioning.
victims closely resembled a woman he was engaged to and then was dumped by. Some psychologists also believe that mutilations are a wish for the killers to re-enter and explore the mother’s body. This also goes back to the childhood of the serial killers. The hatred these killers have for their mother has to be linked to some type of abuse they were exposed to as a child (Wilson & Seaman, 1983, 6). The frustration/aggression hypothesis was also derived from Freud. He believed that aggressive energy build-up must be periodically released before it reached dangerous levels. If it were not released then it would lead to certain acts like serial killing. Others believe that such frustration dissipates naturally without violent acts, and that the theory cannot help in explaining serial murder (Horse, 2001, 5). The development approach is what I talked about at the beginning of the paper. I am going over this theory repeatedly because this is what I believe makes these monsters and I think it can be stopped. This approach goes into more depth about the childhood symptoms. This approach talks about the childhood behavior of bed-wetting, arson and torturing of animals. The bed-wetting is said to be a form of sadistic and hostile rebellion towards parents. Fire setting is associated with violence and torturing animals is a further form of rebellion against keeping pets as cherished friends (Mukherjee, 1998). Physical abuse as a child also plays a prominent role in the development of a serial killer. This abuse creates mistrust, an inability to establish meaningful personal or sexual relationships, feelings of low self-worth, lack of social skills, a sense of helplessness, inability to make decisions, and inability to plan life goals. The sexual abuse will make a person withdrawal into a fantasy life. To protect themselves from going crazy, the people being abused may pretend that the abuse is actually happening to someone else. After a person is abused so long, their fantasy world becomes reality and the killings could start.>GET ANSWER
