Explain What Causes A Serial Killer's Desire To Kill

Serial murder is one of the most baffling crimes that occur in the U.S. and all over the world. Knight (2006) defines serial murder as the killing of three or more people over a period of more than 30 days, with a significant cooling-off period. The cooling off period may be weeks, months or even years long. Researchers have proposed various psychological, biological and sociological theories that offer a partial understanding of the nature of serial murder. Some propose that the basis for criminal behavior is a predisposition to violence as well as a mix between environment, personality traits and biological factors. Serial killers are predominantly male. Only 3 percent of serial murders are committed by women (U.S. News and World Report,

“Serial killers are human black holes; they scare us because they mirror us,” spoke Shirley Lynn Scott, known author and psychologist. This stands true throughout history, as most serial killers blend in with society. Serial killing is formally defined by the FBI as “a series of three or more killings, having common characteristics such as to suggest the reasonable possibility that the crimes were committed by the same actor or actors.” But what exactly drives someone to kill another human being? What plays as a more drastic motivator for their actions, nature or nurture?

Different personalities and mental illness effect people differently may help professionals detect killers before a major disaster. Also, it may be genetic in many families because of genes that develop more and more over time. Serial Killers may be more predictable than other types of killers because of their mental health. Another way a serial killer may be caught or predicted is through family genes and ancestry. A violent gene in distant family can help predict violent people. This paper and information is not meant to scary people or to make people stereotype a group of humans, it is meant for people interested in brain chemistry and to teach them something

According to studies led by King’s College researchers, it has been confirmed that “psychopathy is a distinct subgroup of antisocial personality disorder (ASPD)” (Gregory et. al n.p) and similarly to psychopathy, the more severe ASPD behavioral patterns are, the symptoms can be referred to as sociopathic or psychopathic. Furthermore, according to Nigel Blackwood, Ma, MD.MRCPsych, “MRI scans...found that psychopaths had structural brain abnormalities in key areas of their ‘social brains’” (Gregory et. al n.p). The areas of the brain, in which are deficient in psychopaths, are important when comprehending an individual emotions’, intentions, and moral

Several serial killers have a definitive and common personality profile. Almost every major social, biological, psychological behavioural influence that has been seriously suggested as playing a role in causing crime has been thoroughly thought as potentially

However, more recently, a study led by King’s College London has claimed that there are differences between the brains of psychopaths and other criminal offenders diagnosed with antisocial personality disorder. Dr. Nigel Blackwood who led the research is quoted as saying “We describe those without psychopathy as 'hot-headed' and those with psychopathy as ‘cold-hearted’.” This statement shows a clear distinction between what should be interpreted as a lack of self-control and ability to repress impulses and what should be diagnosed as psychopathy.
The study took MRI scans of 66 men, two thirds of which were offenders who had been diagnosed with antisocial personality whilst the other third were non-offenders considered to not have any personality disorders. Of the 44 offenders, 17 met the diagnosis criteria for psychopathy (ASPD+P) assessed by the guidelines stated in the DSM-IV. Researchers saw that the members of the study diagnosed as psychopaths had notably less grey matter in areas associated with moral behaviour and understanding other peoples’

This literature review focuses on serial killers from a psychological viewpoint while trying to answer the question, “Are serial killers born to kill or are they bred to kill?” Firstly, this review will define a serial killer and the different kinds of killers, then it will take a look at different case studies of children who fantasized about mass killing and identify similarities between the cases attempt to find a way to possibly prevent their fantasies from becoming reality. The debate of nature vs. nurture is also discussed as psychologists and researchers come to the conclusion that environmental factors play a bigger role in the developmental character of a person than genetics, but there is still no definite answer as to why some individuals grow up with the urge to murder other people and/or animals.

The brain can be affected by damage and cause behavior to be expressed differently in every person. Events such as a car crash or childhood abuse can affect brain development and function. Damage to certain areas of the brain can have a variety of effects. The hippocampus controls emotions and is associated with memory, and the frontal lobe is a brain cortex that controls motor functions, problem solving, memory, language, judgments, social and sexual behavior and impulse. When the frontal lobe or hippocampus is affected, a person’s emotion can be out of their control. In criminal cases, brain damage can affect the sentencing of a violent criminal, but to what extent should these abnormalities play a role in their conviction? Much research has been conducted in order to determine the effect that brain abnormalities should have on the conviction of violent criminals. A psychiatrist at New York University, Dr. Lewis, has conducted a study on death-row inmates, how their brains work and what affect the damage had on their conviction. By doing so Dr. Lewis paved the way for other researchers, such as Kent Kiehl and Jonathan H. Pincus to study the brains of violent criminals looking for a answer as to whether or not these criminals should be incarcerated. Over time research has been conducted focusing on mental illnesses and brain damage as the cause of violent acts instead of it being just premeditated murder. Many believe brain damage or mental illness should have no affect on

The question of whether or not man is predetermined at birth to lead a life of crime is a question that has been debated for decades. Are serial killers born with the lust for murder, or are their desires developed through years of abuse and torment? Many believe it is impossible for an innocent child to be born with the capability to commit a horrible act such as murder. But at the same time, how could we have corrupted society so much as to turn an innocent child into a homicidal maniac? Forensic psychologists have picked apart the minds of serial killers to find an answer as to what forces them to commit such perverse acts. Their ultimate goal is to learn how to catch a serial killer before

This documentary specifies that there is no easy answer to what is going on inside the mind of killers, and we cannot simply place these individuals into “neat diagnostic boxes” that explain why their actions turned so violent. However, the investigators present research studying different avenues regarding ways to “predict” the likelihood that an individual will commit violent crime, will maintaining that no method is perfect. Throughout the presentation, viewers are offered mountains of research highlighting a mix of nature and nurture ranging from neurologists from Harvard studying brain patterns affected by genetics, to psychologists studying maternal care and attachment during infancy.

Introduction: This investigation examines the biological causes for serial killers’ psychopathic tendencies and examines those same biological factors in both men and women to find the correlation between a higher rate of male serial killers and the biology behind their actions. It is imperitave to first know what a serial killer is, and what makes them such a cold fish. There are sections of the brain that do have control over a human being’s personality, where that individual can either develop into an average person or join the other one percent of psychopaths living in the world today (due to physical damage or chemical imbalance in the brain). These specific sections of the brain are different in males then in females, some components of the brain vary in size etc. between sexes. It is crucial to have all these pieces, with this information its then possible to form a conlusion to the surfaced question.

Though serial killer may have a fairly specific definition, there is no single precise profile for the serial killer. Each has a unique identity, set of motives and methods, and a unique psychopathology that would attempt to explain the mens rea, that is, the purpose or intent of the murder. “Psychological profiling is an investigative tool used strictly to answer the how of the crime, not the why” (Severence et al, 1992; Lanier and Henry, 1998). By examining the psychological make-up of the serial killer, it is often possible to explain the behavior, which might make it a useful tool in solving crimes.

Due to its primary role in processing memory and emotional reactions, over the last decade and a half psychologists have been linking the amygdala to psychopathy. It is involved in aversive conditioning and instrumental learning and is thus involved in all the processes that, when impaired, produce the same functional impairments displayed by psychopaths. Two famous studies conducted by Tiihonen and Kiehl respectively have confirmed this. Tiihonen used a volumetric MRI to test and confirm the positive correlation between low amygdaloid volume and a high degree of psychopathy in violent criminals (measured by the Hare checklist-revised) while Kiehl used a functional MRI to prove reduced amygdala response during an emotional memory task in individuals who scored high on the Hare checklist-revised. However, both these studies along with numerous others were conducted using violent offenders as subjects rather than individuals with psychopathy. Although many psychopaths do exhibit violent tendencies, not all violent offenders are necessarily psychopaths. A study conducted by Raine is one of the few that did focus only on individuals exhibiting psychopathy. In his study Raine was able to show reduced prefrontal grey matter in his test subjects. Unfortunately though, he was unable to differentiate between grey matter in different regions of the prefrontal cortex. It is however clear that there is one region of the frontal cortex that could be

It is very rare these days to turn on the news and not hear about a crime or a murder. Crime is a common occurrence yet many times it is difficult to understand how someone could bring themselves to do these things. It does seem to make any sense why a young handsome man from a good family would want to kill someone and then be able to go through with it. This leads one to wonder if the brains of people who behave in socially unacceptable ways are different from everyone else's brains. There is a substantial amount of evidence that suggests some criminals do have differences in their brains that most likely contribute to their behavior. Many of these individuals have Antisocial Personality Disorder and

Behavioral neuroscience or biological psychology employs the principles of brain pathology to the study of human behavior through genetic, physiological, and developmental operations, as well as, the brain’s capacity to change with experience. Since the second world war, crime was largely attributed to mostly economic, political, and social factors, along with what psychologists termed at the time, the “weak character” of mental disturbance, and brain biology was rarely considered. However, new advances in neuroscience and technology have allowed a number of studies that link brain development, impairment, and injury to criminal violence. This emerging field of psychology explores the brain at a microscopic level, focusing studies on the roles that the brain’s neurons, circuitry, neurotransmitters, and basic biological processes play in defining and molding all human behavior.
