Research on Psychopathy: A Personal Disorder Essay

When we look at how fragile each one of our lives are, we need to take a minute and realize the different characteristics that form us into who we are today. Studies have shown that there are characteristics within the behavior of an individual that can be linked to the specific behaviors demonstrated by an offender that would classify them as a psychopath. Along with other research that looks into an individual’s genetics to see if that plays a role in defining or making a psychopath. John Allen Muhammad, also known as the D.C. sniper, was labeled as a psychopath when he terrorized D.C. for two weeks, taking thirteen victims and killing ten of them. This paper will go over the behaviors that constitute psychopathy, and the behaviors that

(Gao, 2011). Henry Greenwald sums it up perfectly with this quote, “Usually when we talk about the psychopath we are talking about the unsuccessful psychopath. The reason why we generally do not discuss the successful psychopath is because we would then have to discuss many of the rulers of our world. This paper will delve into the biological explanations of psychopathy and how differences and dysfunctions in certain brain regions can result in the outward manifestation of these psychopathic traits. This paper will further address the non-criminal psychopaths and the criminal psychopaths, provide brain structures and functions that distinguish these subgroups and finally, will address biosocial factors that displace psychopaths towards the path of crime and

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

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’

Psychopathy, in both the mental health and criminal justice systems, has emerged as one of the most important clinical constructs of the 21st century (Hare, Clark, Grann, & Thornton, 2000, p. 623). Where clinically, psychopathy is traditionally described as a combination of inferred socially deviant behaviors and personality traits. Some traits and behaviors a psychopath is seen to possess are commonly known, for example, to being impulsive, selfish, aggressive, lacking remorse, shame, feeling for others, pathologically lying, and having asocial or antisocial behaviors (Hare, & Neumann, 2006, p. 59-60). One of the reasons as to why psychopathy has come to see an increase in the development of its theoretical and applied interest is the

Accordingly, there exists a small group of people who exhibit most-to-all of these specific and peculiar characteristics and behaviours. This particular group of predators presents numerous challenges to morality, safety and policy. For instance, because a "psychopath" may display a general coldness toward others, they are more likely to commit criminal acts, and afterward not respond to punishment or deterrent tactics. Hare’s psychopathy checklist when used as a tool to identify psychopaths prevents harmful exposure of non-psychopaths to this dangerous group of offenders. For this tool to work effectively there must not be significant overlap of the specific characteristics used in the PCL-R to identify psychopaths as in the general population of non-psychopaths. In other words, the psychopath must

Generally defined, psychopathy is a personality disorder that is characterized by a combination of superficial charm, strong antisocial behavior, and extreme sensation-seeking and impulsivity. Psychopaths make up approximately 15% of the prison population while between 50% - 80% of that prison population could be diagnosed more broadly with antisocial personality disorder (Ogloff, 2006). While the percentage of those diagnosed with antisocial personality disorder is high, the percentage of psychopaths in prison is extremely overrepresented compared to the average population which hovers between 1% - 4% (Ogloff, 2006). While it would be disingenuous to say that all psychopaths are dangerous, their overrepresentation in the population of violent

A scientific study in England compared the brains of psychopaths with a group of mice. The result of this experiment directly correlates with the mental and physical behaviors of psychopathic humans. One mouse

It is very rare to study something that is as fascinating yet as bewildering as the distinctive paradox, that is the human brain. Every individuals conflicting behaviour and elaborate character that make them the person they are must have a justification. I originally established a fascination in forensic psychology as I read about a sequence of homicides committed by Gary Ridgway, otherwise known as the “Green River Killer”. Upon discovery of this case, questions began to pervade in my head about what may be the cause for an individual to execute such things, and just how someone’s mind could be so peculiarly dissimilar to my own.

The concept of psychopathy originated in the 1800s to describe individuals that consistently failed to conform to societal norms and exhibited antisocial behavior that did not fit the concept of mental illness of the time period. While, psychopathy was a common term used to describe individuals suffering from this disorder other descriptions were coined such as “Pinel’s term “manie sans delvie” meaning mania without delirium in the 1700s, to describe patents whose ‘affective faculties were disordered’” or Pritchard’s term “moral insanity” (Ogloff 520). In the 1930’s Partridge argued that psychopathy was a social rather than a mental disorder and proposed that the concept of sociopathy be introduced as a more accurate description. The American Psychological Association adopted Partridge’s term for their Diagnostic and Statistical Manuel in 1952. However, in 1968 the American Psychological Association changed the diagnostic label from sociopath to “personality disorder, antisocial” for the Diagnostic and Statistical Manuel – II that continued through to the DSM - III in 1980 and the DSM - III-R in 1987 and the DSM - IV in 1994. Today the Diagnostic and Statistical Manuel categorizes antisocial personality disorder as a personality disorder and it is named as such. Unfortunately, not much research has been conducted

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.

“Psychopathy is a personality disorder characterized by an inability to form human attachment, aggressive narcissism, and antisocial behavior defined by a constellation of affective, interpersonal and behavioral characteristics, most of which society views as pejorative” [1]. Some of these characteristics include irresponsibility, grandiosity, cunning, deceitfulness, selective impulsivity, sexual promiscuity, lack of empathy, etc. People who are psychopathic display not only antisocial behavior but also emotional impairment such as the lack of guilt. They are able to prey on others using their charm, deceit, violence or any other methods that allow them to get what they want. A strong feature of most of the behavior

Psychopathy is a disease of the mind, in which the psychological state of someone has emotional or behavioral problems serious enough to require psychiatric evaluation. Psychopaths have no concern for the feelings of others and a complete disregard of any sense of social obligation. Psychopaths are characterized by lack of empathy, poor impulse control and manipulative behaviors. They use charm, manipulation, intimidation, and the use of severe to mild violence to satisfy their own needs.

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.
