Craparo, A. Schimmenti, V. Caretti (European Journal of Psychotraumatology, 2013) The source is a study done on a group of violent offenders from Italy in order to determine the effect of physical trauma/neglect in childhood on the development of psychopathic behaviour in adulthood. The source investigates 22 criminal offenders who, at some stage in their lives, have had a traumatic (physical) experience. The scientists conducting the experiment used the Hare Psychopathy Checklist—Revised (PCL-R) which measures the presence of psychopathic tendencies in an individual by “checking” a number of personality traits. The study found that the offenders who experienced early childhood physical trauma scored the highest in the Hare Psychopathy Checklist—revised test.
The connection loss can cause many problems for the serial killer’s thought process. A person’s negative emotions are censored by the prefrontal cortex which is then controlled by the amygdala. The amygdala responds to the emotion that is needed after the impulse reaches the prefrontal cortex. When the connection of the amygdala and the prefrontal cortex is low, the body has trouble processing negative emotions (Brogaard 2). The lack of negative emotions can make the serial killer lose the recognition of when they or someone around them needs empathy, is embarrassed or is hurt by others’ actions.
The creator of the Psychopathy Checklist-Revised, Dr. Robert Hare, wrote a book entitled Without Conscience: The Disturbing World of the Psychopaths among Us. In his book, he states that “…compared with other major clinical disorders, little systematic research has been devoted to psychopathy…” This just goes to show that there could possibly be even more to understand about psychopathy than what is already known by medical professionals today (Hare). However, from what is already understood today in regards to the cause of psychopathy, we have found that the cause is genetic and linked to abnormalities that appear in the brain.
Adrian Raine, criminologist and author of "The Anatomy of Violence: The Biological Roots of Crime," has said before, is a very important factor in criminal behaviour that affects about 75% of a person’s criminal activity. In his book, Raine explores the many evidences that lead up to biological and genetic influences on crime
Jails and prisons have a greater responsibility that incapacitation. The focus should be placed on factors that the most significant factors that are attributed to criminal conduct. After the determination of the risks of the offender, the focus should be placed on factors that are the most important influences that are attributed to criminal conduct. Many issues may be considered a factor; however, priority should be put on those that are known to reduce recidivism. According to O'Riordan and O'Connell (2014), personality factors are much more linked to a crime that socio-economical class (98).
The prefrontal cortex stops the violent impulses from becoming actions. Without a properly working prefrontal cortex, those violent impulses are carried out. The problem is that half of the serial killers have a different brain functionality, but the other half does not. That other half has the
Furthermore, the psychology of criminal behavior, psychology, and criminology all have a primary objective of achieving an understanding of the variation in the criminal behavior of individuals (Andrews and Bonta , 2010). Empirically, the study of variation in criminal behavior is done by the studying of covariates (Andrews and Bonta , 2010). The primary covariates that PCC studies are biological, social, and psychological (Andrews and Bonta , 2010). Although, criminology tends to assess criminality at an aggregate level, in comparison to the psychology of criminal conduct’s focus on an individual level. Additionally, a psychology of criminal conduct involves applying what is learned by the studying of psychological information and methods to the predicting and influencing the propensity of criminal behavior on an individual
Esbensin, Peterson, Taylor and Freng (2010) implies that “ young people who have committed serious violent offenses have the highest level of impulsive and risk-seeking tendencies.” Moreover, extreme violent criminal activity being performed in front of youth increases the risk of them performing acts of extreme violence themselves. Because youth see those acts as acceptable so committng those violent activities make youths to become ruthless. Smith and Green (2007) assert that violent activities becoming ruthless and the perpetrators even more ruthless.
Introduction The views over the mentally ill and their relationship to violence are negative to the public eye. The mentally ill are looked down upon the general audience causing the mentally ill to become its own stereotype. Although, the public eye may view the mentally ill as violent researchers have found nothing but the truth. The research actually does show a correlation between the two but has a few reasoning’s behind the numbers of violence seen in the mentally ill.
Where external and internal factors play a part and they are fated to be a criminal. The scientific grounds are offenders and people who have not yet offended can be given help, and they can be diagnosed by experts and receive treatment needed to not offend (Cavadino, 2007
"Some are highly predatory, highly psychopathic and have repeated offenses, making them more likely to re-offend," he explains. In the last 10 years, psychologists have made substantial advances in clearly identifying factors that increase an offender 's risk of committing an offense after release, Hanson says. These factors include the number of offenses, intimacy deficits, sexual
