I am not surprised by my discovery here; I know from past studies which parts of the brain control various actions and thoughts, so it was only logical to determine that these centers for violence and emotion would have to be altered in some way. However, it did intrigue me that different types of killers show different brain abnormalities. Although it makes sense to me now, it’s rather interesting that various effects on the brain can elicit such a wide variety of responses. It is also interesting that not one single factor can make someone a killer; if an individual has brain damage that predisposes them to a life of violence, a good childhood could counteract it. Aside from what makes a serial killer, once an individual is established as one, it also interests me to know what they think of what they do and while they are doing it. It interests me to know what thoughts run through their minds as their victims are begging for their lives. Do they enjoy the agony of their victims? Do they feel nothing but anger? No matter where their motivation comes from, either DNA or home life, their thought process and reasoning for their victims and various patterns have piqued my interest. My third question is: what does a killer’s general psychology consist of? According to the article “What a Killer Thinks,” by Dave Cullen, there are three categories of killer motivation: the psychopath, the delusionally insane, and the depressed. In serial killing, the motivation falls into the category of psychopaths. The psychology of these people are generally that they simply enjoy killing or feel a need to kill, which is why they murder so many people. According to the article, they state that “They seem to be born with no capacity for empathy,... ... middle of paper ... ...ks Cited Cullen, Dave. “What a Killer Thinks.” Newsweek6 August 2012: 1.

The motives and backgrounds of serial killers is a vexing topic. Not two people are the same, so therefore their motives differ. The different types of serial killers are: hedonistic, power seekers, gain, mission oriented, visionary, psychopathic, comfort, medical, organized, and disorganized. Motives of these murderers range from fear of being rejected, to “getting rid of what they deem bad,” or even to get sexual satisfaction from the suffering of their victims.
...theorize that serial killers have brain damage or other biological abnormalities that contribute to their actions. Damage to areas like the frontal lobe, the hypothalamus and the limbic system can contribute to extreme aggression, loss of control, loss of judgment and violence. Henry Lee Lucas, who was convicted of 11 murders, was shown to have extreme brain damage in these areas, probably the result of childhood abuse, malnutrition and alcoholism. Arthur Shawcross, another 11-time serial killer, was found to have had several brain injuries, including two skull fractures. While in prison, he suffered from headaches and often blacked out. Bobby Joe Long, convicted of nine murders, stated at one point, "After I'm dead, they're going to open up my head and find that just like we've been saying a part of my brain is black and dry and dead" [source: Scott].

There are many motivations involved in serial killings such as the fear of rejection, power, and perfection. Most serial killer tend to be intensely afraid of rejection and are very insecure. They try not to cultivate a relationship with their intended victim so as to avoid the possibility of being abandoned, humiliated, or exposed. There are many serial killers who engage in intercourse - the ultimate form of intimacy - with their victims, and many times also with the corpse. In doing this there is no risk of rejection. Serial killers also find satisfaction in prolonging the suffering of their victims, giving them the feeling of power over the victim. In doing this the get to decide if and how the victim will either live or die.
Some psychologist believe that if a serial killer displays or kills his victims in such a way then it qualifies as fulfilling as sexual desire. These killers are usually diagnosed with a mental disorder referred to as sexual sadism. Psychologists refer to serial killers who kill in this manner as sexual sadist. A sexual sadist enjoys the ‘suffering or embarrassment of others to the point of arousal’ (Serial Killers and Sexual Sadism). Sociologists believe that a serial killer needs to “fulfil a sexual desire by turning a fantasy into a controllable reality” (Serial Killers: Nature vs. Nurture). Sadist crave the dominance and control over their victims because they feel as if they cannot control other aspects of their life. Another biological factor derives within the DNA of the person. Many killers have the “MAO-A gene (monoamine oxidase A). This gene, which has been the target of considerable research, is also known as the "warrior gene" because it regulates serotonin in the brain. Serotonin affects your mood — think Prozac — and many scientists believe that if you have a certain version of the warrior gene, your brain won't respond to the calming effects of serotonin (A Neuroscientist Uncovers a Dark Secret).” With this gene psychologist and scientist alike believe that this can foretell a serial killer before he becomes a serial
A serial killer is traditionally defined as the separate killings of three or more people by an individual over a certain period of time, usually with breaks between the murders. (Angela Pilson, p. 2, 2011) This definition has been accepted by both the police and academics and therefore provides a useful frame of reference (Kevin Haggerty, p.1, 2009). The paper will seek to provide the readers with an explanation of how serial killers came to be and how they are portrayed in the media. Several serial killers have a definitive and common personality profile.
It has been proven by psychologists and stated by serial killers that their childhood is one of the many problems they faced that led them to become serial killers. The childhood of a typical young boy would consist of loving parents, a stable home and having friends. As for serial killers, this is not typical at all. During the childhood of a serial killer, it is not uncommon that he or she was abused, raped, or even attempted suicide along with many other harmful acts that a child should not be faced with. There have been many studies on the childhood of serial killers, and how they grew up compared to other young children.
Serial killers are defined to “be driven by instinct and desire to kill.” In a study done in 2000, Dr, Richard Davidson says, “people with a large amount of aggression – in particular people who have committed aggressive murders or have a social disorder – have almost no brain activity in the orbital frontal cortex or the anterior cingulated cortex while activity in the amyglade continued perfectly. The orbital frontal cortex and the anterior congulated cortex control emotional impulses while the amyglade controls reactions to fear.” Davidson concludes his research claiming that although environment can and will affect a serial killer’s thoughts, it is a killer’s genetic makeup that inevitably creates murderous thoughts.
Serial killers have captivated the attention of scientists from the first signs of their existence to modern day. Interested by these killers’ inhumane actions, researchers set out to determine the cause of such graphic, horrific crimes. The brain has been brought into question regarding the motivation of these cold blooded killers. After extensive research, abnormalities of both the chemical composition and material makeup have been identified within the brains of numerous serial killers. These differences are more than mere coincidence, they are evidence that killers do not think in the same way. The killers’ drives and motives are irregular, just as their brains are. Not only are these variations interesting, but they are also crucial to the justice system in regards to the punishment of past, future, and present sequential murderers. It is important that as a society we learn the differences in the mind of a killer, and also recognize and understand them. A serial killer’s brain greatly differs in function from the average citizen’s brain due to physical variations in the brain and a different chemical makeup.
We can all agree that serial killers are unpredictable scary people but when it comes to why they kill, everyone has a different view. In my research paper I will get into the mind of a serial killer and try to figure out what exactly sets them into uncontrollable rage.
Serial killers have many frightening facets. The most frightening thing about them is that experts still do not know what makes a human become a serial killer. Many experts believe serial killers become what they are because they have a genetic disposition or brain abnormality while other experts believe that a serial killer is created by childhood abuse; and some other experts believe that it is a combination of both brain abnormalities and abusive childhood experiences that creates a serial killer. A murderer is considered a serial killer when they “murder three or more persons in at least three separate events with a “cooling off period” between kills” (Mitchell and Aamodt 40). When defining a serial killer, their background, genes, and brain are not mentioned; perhaps one day those aspects of the serial killer can be included.

'Serial murder'; has long been a term used to describe those human beings that repeatedly commit heinous crimes. It is rare that the average person probes the mind of a serial killer without bias. However, what lies behind the eyes of a serial killer deserves more than the cold hard look that society so often gives (Aaronson, Inter...
The brain is the most complex organ in the human body. Since the beginning of time, scientists and neuropsychologists alike have studies its composition and how it influences human behavior. However, no human behavior has baffled researchers more than serial murder. Serial killers are dangerous animals that act upon bizarre influences that have fascinated the human race for thousands of years. Many wonder what could cause a person to take the life of another innocent soul. Do internal factors cause them to do it? Is it their environment? What causes a serial killer to kill?
The nurturing of individuals plays a role in the making of killers, as 94% of serial killers had experienced some form of abuse as children and 42% have suffered severe physical abuse (Australian Institute of Health and Welfare, 2010). A child abuse is a determining factor, in which supports the idea that serial killers and psychopath, are influenced significantly by nurture (Australian Institute of Health and Welfare, 2011). In most cases social, cultural and physiological determinants all play a role in influencing serial killers to grow into a mass murderer. It is important that physiological and social determinants can be identified, so they could be altered for the purpose of preventing the number of crime.
