Why Do Psychopaths Have Normal Brain

When most people hear the word psychopath their mind forms a picture of a wild-eyed, rambling, lunatic who is often restrained in a straitjacket. The media has helped this belief along the way with slasher horror films and grisly CSI episodes depict these strange humans. However, the average psychopath is much harder to spot than most people believe. In fact, most of them are extremely difficult to distinguish from ordinary humans. They outwardly appear normal and many do not find it difficult to blend into common society. They can interact with others, hold successful jobs, and effectively keep themselves out of trouble. Most are not the sadistic killers many people think they are. Psychopaths are people born with problems (Bartol 105) or

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

One of the first things that come to people’s minds when they hear the word psychopath is Ted Bundy. Bundy spent most of the 1970’s killing 30 or more young woman who happened to resemble his ex-girlfriend in some way. The exact time and number of Bundy’s kills will likely never be known. Ted Bundy is what is considered a successful psychopath. Psychopathy is a form of antisocial personality disorder (ASPD). Not every person with ASPD is a psychopath, but every psychopath has ASPD. No one knows exactly what causes this disorder, but there has been some speculation over the decades. The two main ideas is that an genetic influence causes psychopathy or an environmental influence causes psychopathy. The neurotransmitter MAOA has been linked to several brain structural differences in the brains of a psychopath when compared to the brain of a non-psychopathic person. Multiple studies have linked childhood abuse to the psychopathy development. Both of these causes have been shown to influence psychopathy development but it is my hypothesis that genetics hold

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’

Psychopaths have been around for more than a century, and have found themselves to be able to make the public fear them. Belle Gunness, the Zodiac Killer, and John Wayne Gacy are all examples for the character traits compatible with psychopathy and have been able to provide more reason to the research of psychopaths. Statistically, psychopathy is found in three percent of the male population and in one percent of one percent of the female population. A psychopath’s behavior of exploitation, lying, recklessness, and arrogance has been studied to further understand how their brain structure is different in MRI scans and how they are able to use special abilities to catch its victims. Many research studies have been able to provide more information

Unfortunately, changing the biological composition of their brain is not as easily achieved. Studies have found multiple areas of interest when studying the brain structures in psychopaths. These minor differences provide a world of knowledge into what composes a psychopath. Since each area of the brain serves a specific function, determining the effects of abnormalities correlates to the area of interest. Due to the major costs associated with many tests, they are not performed unless indicated. Brain imaging research on psychopathy: Implications for punishment, prediction, and treatment in youth and adults provides us with the very new research that has been conducted on both adult psychopaths, and juveniles that display callous unemotional traits (CU) and have disruptive behavior disorder (DBD) (Umbach et al., 2015). Research done has not given conclusive results that fits for each and every psychopath, but an area of commonality is the amygdala. “In addition to their finding of significant bilateral volume reductions in psychopaths, Yang et al. (2009) identified localized surface deformations in four of the 13 nuclei: the basolateral, lateral, cortical, and central nuclei.” (Umbach et al., 2015, p.296). The paralimbic structure is seen as the emotion processing center of the brain, controlling all emotions including empathy and conditioned fear

Genetics do play a part in psychopathic tendencies, but also the environment you grow up in and what you are exposed to plays a role in it as well. For example, Ted Bundy. Crime Feed Staff (2015) discovered many troubling details about the way he grew up. He lived a childhood full of lies. He grew up thinking that his birth mother was his sister and that his grandparents were his parents only later to learn that his sister was actually his mother and that his grandfather was possibly his father making him a product of incest. There were many things that Bundy did as a child that showed his strange attraction to violence (p.1). Bundy was exposed to pornography as a young age and became addicted, he needed to fuel his addiction and his fantasies became so unbearable he turned it into his reality. Dr. Al Carlisle, the psychologist who evaluated Ted Bundy, concluded that “Because they have painful memories from abuse, disappointment, humiliation, frustration, or being bullied, they have turned to fantasies

Psychologist Donald Hebb once answered the question of nature vs. nurture by responding with a similar question, “Which contributes more to the area of a rectangle, its length or its width?” I find this to be a very interesting and true argument. As we know, a rectangle’s area can be determined by multiplying its length by its width, or vice versa. If either one of these variables is unknown, you cannot determine what the area is. They both have an equal contribution to the equation. Similarly, it is impossible to single out either nature or nurture as the reason that somebody becomes a psychopath. They both contribute equally to the equation.

This is the age of technology so there are a lot of developments in the study of the psychopathic brain. Researchers have been looking into the criminal mind, studying it and trying to find out what makes it tick? There is a huge debate in the scientific community on whether they can narrow a serial killer down to dysfunction in the brain or a specific gene that could possibly be inherited, or does it all comes down to simply being a victim of a bad situation? Science has a lot of good evidence to support its different ideas on what makes a person a serial killer. However, there are millions of variables that have to be taken into account. More to the point can we actually pinpoint with science out of thousands of variable studies whether a psychopath is born or are they made?

As read in the article Psychopaths Get A Break From Biology: Judges Reduce Sentences If Genetics, Neurobiology Are Blamed, published in Science Daily, judges say psychopaths should receive longer sentences than non-psychopathic people, yet believe psychopaths possess the same amount of free will. A study done in Utah by James Tabery, Lisa Aspinwall and Teneille Brown surveyed 181 judges from 19 states on how they would sentence psychopaths, and the results were simply paradoxical. Researchers gave all judges the same example of a case involving a psychopath as a defendant. This real-life case involved a psychopath brutally beating a clerk. One fourth of the judges were given genetic and neurobiological reasons for why the individual should

An associate professor of Psychology and Neuroscience from the University of New Mexico, and a District Judge from Denver, Colorado, wrote in an article, The Criminal Psychopath: History, Neuroscience, Treatment, and Economics, and stated that a big difference in psychopaths is that individuals with psychopathic personality, or psychopaths, have disproportionate impact on the criminal justice system (Kiehl and Hoffman, 2011). Psychopaths are 20 to 25 times more likely than non-psychopaths to be in prison and are four to eight times more likely to violently recidivate compared to non-psychopaths (Kiehl and Hoffman, 2011). Kiehl and Hoffman also noted that psychopaths are resistant to most forms of treatment (Kiehl and Hoffman, 2011). Kiehl and Hoffman noted in their writing that psychopathy is a constellation of psychological symptoms that typically emerge early in childhood and affects all aspects of a sufferer’s life (Kiehl and Hoffman, 2011). These symptoms can affect all of their life relationships with family, friends, school and

The researchers, based at King's College London's Institute of Psychiatry, said the differences in psychopaths' brains mark them out even from other violent criminals with anti-social personality disorders (ASPD), and from healthy non-offenders. The study showed that psychopaths, who are characterised by a lack of empathy, had less grey matter in the areas of the brain important for understanding other people's emotions.

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

There are various physical and behavioral differences between a psychopath and an average person. In the book The Social Brain: Evolution and Pathology, doctors of psychiatry Hedda Ribbert and Wulf Schiefenhövel explain psychopath’s core features as a lack of empathy, persistent disregard for the feelings of others, reduced emotion, and have autonomic hyperresponsivity to sad and fearful

The biology and environment play a huge role in these offender’s lives. The interaction between neurological and having a disadvantaged environment can put them at a higher risk of becoming an offender. These offenders can be seen as psychopaths because of the factors that are a play. Throughout their childhood they begin to have antisocial conduct. Then during adolescence they begin to have cumulative consequences and in adulthood they start to commit criminal behavior.
