Characteristics[ edit ] Some commonly found characteristics of serial killers include the following: They may exhibit varying degrees of mental illness or psychopathywhich may contribute to their homicidal behavior. Individuals engage in paraphilias which are organized along a continuum; participating in varying levels of fantasy perhaps by focusing on body parts partialismsymbolic objects which serve as physical extensions of the body fetishismor the anatomical physicality of the human body; specifically regarding its inner parts and sexual organs one example being necrophilia.
The Psychology of serial killers There are many different levels of criminal psychology. There are some criminal, or forensic, psychologist that focus mainly their research on serial killers.
This time between the murders often makes the killings not seem connected. Depending of course, on the method used to murder the victim. In most cases the serial killer's victim don't personally know the killer. This implies that a serial killer's motive is more psychological than material.
Studying the Brain of Serial Killers: As research continues in the field, it is more commonly believed that the symptoms manifested by serial killers - regardless of their classification - are the result of brain abnormalities.
For instance, using medical imaging techniques, neuroscientists have discovered that the brains of psychopaths have noticeably thinner tissue in key subcortical areas. These regions span what doctors call the limbic system. It also spans other structures, such as the orbitofrontal cortex and the temporal pole, that are adjacent to the limbic system.
These regions of the brain are collectively known as the paralimbic system, and believe it may hold the key to understanding psychopaths.
This is because the paralimbic system controls basic emotions such as fear, pleasure, anger — and handles decision making, reasoning and impulse control. If this tissue is damaged or underdeveloped, then that person may have a decreased ability to register feelings or assign emotional value to experiences.
It explains a great deal about the behavior of psychopaths, who have great difficulty feeling emotions. Freud, a more classic form of psychoanalytic theory, described the id as the part of the mind that regulates instinctive impulses and primary processes. The ego, Freud said, mediates between the conscious and the unconscious and is responsible for a sense of someones personal identity.
And the superego acts as a self-critical conscience, reflecting the social norms learned from parents, teachers and other authority figures. In psychopaths, an abnormal paralimbic system could weaken the ego, which would allow the id to direct behavior, leading to the need for immediate gratification.
Other abnormal brain functions could also compromise the superego, allowing an individual to harm others in their pursuit of self gratification without experiencing feelings of guilt or remorse. The Serial Killer Environment: Everything we need to know about serial killers can't simply be explained by biology.
Data shows that information hardwired in DNA only accounts for 50 percent of the variability among people who exhibit adult antisocial traits.
Basically, genetics can only account for so much. A persons environment has equal importance in shaping how a person develops. Many, but not all, serial killers suffered some kind of trauma in their childhood.
Childhood trauma played a key role in the lives of numerous serial killers. John Wayne Gacywho murdered 33 young boys, suffered greatly at the hands of his abusive father.
Gacy was brutally beaten and saw his beloved dog shot while he watched. Aside from physical abuse, he withstood verbal assaults, listening as his father called him "sissy" and "worthless.

Although they were rescued by their mother, the trama they shared from the incident must have been significant. Sometimes, the abuse isn't so obvious. Jeffrey Dahmermurdered 17 people in the late s and early s, seemed to have a normal childhood. He was described as happy and bubbly, although court records state that Dahmer was a withdrawn child who was fascinated with dead animals.

Reports say he may have been sexually molested by a neighbor boy in He also may have also been traumatized, at age 4, by an operation for a hernia. Most children can endure such abuses without suffering long-term psychological damage, others can't.
Those who can't, often fail to develop an appropriate "attachment" to their caregiver. Without that connection, children may never learn to trust the people around them.
Instead, they turn inward, creating a fantasy world that becomes their source of gratification. Usually when challenged, they react violently and never feel sympathy or remorse for the harm they cause.
