Biological Theory Of Antisocial Behavior

This can be applied to the behaviors of criminals. According to Fishbein (1990, pg.37), “behavior [is] primarily attributed to inherited predispositions and genetic influences.” Nurture is the environmental influence that shape human behavior (Fishbein, 1990, pg.37). Human genetics and environmental factors contribute to the uniqueness to a person’s behavior. However, there are underlying qualities in a criminal’s historical background. Aspects of the nature and nurturing of a criminal behavior includes some problems with earlier biological explanations and some recent biological explanations which have overcome the weaknesses of

The same psychiatrist, Johnathan H. Pincus examined 14 other death row inmates who had murdered when they were under the age of 18 and realized that they all had the same factors of neurologic damage, abuse, and paranoid thinking (Pincus, 29). A study done by Lisa Marshall and David Cooke shows the differences between the childhoods of psychopath criminals and non-psychopath criminals. They used the Psychopathy Checklist-Revised and the Childhood Experience of Care and Abuse to show how much the environment your surrounded with as a child can affect your adult life. Not only did they study the results of familial childhood factors such as neglect, physical abuse, and psychological abuse but they also looked into societal factors such as negative school experience and negative school performance. Results showed that “Inadequate or incompetent parenting leads to insecure attachment bonding that forecasts low levels of empathy, compliance, cooperation and self control.” (Lykken,199). The most obvious differences in the childhoods of psychopath criminals and non-psychopath criminals were in parental discipline, parental neglect, and negative school performance. (Marshall and Cooke, The Childhood experiences of psychopaths). Another environmental factor that should

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

Biological factors alone are not a sufficient reason why crime occurs. An example would be looking at testosterone and adult deviance. Most studies have shown no correlation with circulating testosterone and behavior. However, there is significance to examining biological factors. The answer lies in the fact that biological explanations of crime understate the important role of social conditions. (Conklin, p 93). When looking at biological and social combined, there is a moderately strong relationship between testosterone and social integration while growing up. Social integration can be fragmented due to less social opportunities by being in lower-class status, unmarried, and an unstable work history. (Conklin, p 96).

Genetics and behavior relations has been a controversial topic for several years, however, as time has passed so has the demand for proof or disproof of the relationship. One of the most important reasons for the need to define this relationship is to uncover the truths behind violent or delinquent behavior. Also, it is important that we can weed out people who make false claims that their genes are responsible for their actions in order for us to appropriately distribute penalties or treatment. Another reason is that if we do find truths to these claims we can find ways to treat these behaviors for better outcomes. Though many studies have been conducted to reveal associations, more research is yet to be done that explores all connections and detailed backgrounds of those involved in the studies. To begin validating our theories, we must use genotyping, which is the comparison of an individual’s genetic make-up through exploration of their DNA sequence then comparing it to the DNA sequence of another individual or a reference sample. Utilizing genotyping, we are able to view the alleles an individual inherited from their parents (slide 4).

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

Antisocial behaviour (ASB) broadly encompasses human character traits and behaviours that are generally viewed as unpleasant or immoral, such as reduced empathy, aggression and violence. Consequently, ASB is unconducive to forming healthy interpersonal relationships and functional living and on a large scale is socio-economically detrimental to societies. Therefore, research into ASB’s aetiology is important for potentially informing its prevention and management and in turn reducing its negative outcomes. This essay investigates the possible causal role of prefrontal cortex (PFC) dysfunction and structural abnormalities in ASB, focusing on specific PFC subregions; as well as the roles of other brain regions, genetics and the environment. It argues that there is significant evidence that the dysfunction of several brain regions, including the PFC and areas of other lobes, can lead to ASB. The underlying reason(s) for the dysfunction may be brain damage and/or genetic and environmental influences.

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

The principles of the biological theories allow us the understanding that all biological theories should evaluate common factors that relate to each other from one biological theory to the other (Schmalleger, 2012). The first parts of the biological theory assess the importance for the theories to make a connection between criminal behavior and the human brain and a person’s personality and the studies of neurology and neurochemistry. This meaning that a person’s ability to control antisocial behavior stems from their environment and the and family genes gives the person directly into right and wrong. There is also a standard that should evaluate the connection between different groups such a sex and racial makeup that that of criminal behavior as well as human instinctive behavior (Dretske, 2014). The link between the evolutionary development of a person criminal behavior or ability to

Biosocial theories believe biological or genetic risk factors along with their environment impact an individual’s predisposition to engage in criminal behavior throughout their life. The biological risk factors tied with their environment can also impact an individual’s predilection to develop antisocial behavior or tendencies, violent or aggressive behavior, impulsivity, lack of social responsibility and their ability to learn complex behavior patterns. Several empirical studies regarding biosocial theory and its components will be reviewed within this paper followed by an explanation as to why a policy in policing and corrections with its basis in biosocial theory would not be effective.

One researcher studied a theory relating to sociopaths and their antisocial behavior. This specific study proposed a theory that a primary sociopath is lacking in moral development and does not feel socially responsible for their actions. This type of sociopath is a product of the individual's personality, physiotype, and genotype, which supports the theory that a person’s genotype is the significant factor in the development of criminality. There is a secondary sociopath that develops in response to his or her environment because of how and where they were raised. Living in an urban residence, having a low socioeconomic status, or poor social skills can lead an individual to being unsuccessful in reaching their needs in a socially desirable way, which can turn into antisocial or criminal behavior. This supports the theory that the environment is the significant factor in the development of criminality. With these studies, it shows that both the genetic make-up of an individual as well as the environment play an important role with what kind of person they are going to be as an adult.

One factor that influences the likelihood of criminal behavior involves a person’s genetics. Certain inherited behaviors can lead people to be more likely to have criminal behaviors. Stated in the article "The Criminal Mind,” Arian Raine explains, “More than 100 studies of twins and adopted children have confirmed that about half of the variance in aggressive and antisocial behavior can be attributed to genetics.” (Raine). Aggressive and antisocial behaviors are found in many criminals. Research proves that these behaviors can be due to genetics, and this makes these behaviors a genetic influence to criminal behavior. Additionally, anybody can be a criminal, but gender plays a role in their chances as well. In the article “Born

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.

For the most part, biological theories of crime and deviance have had an unsuccessful and undistinguished career among sociologists. The Italian physician Cesare Lombroso suggested that someone who is born criminal possesses atavism or primitive evolutionary characteristics that produced violent, savage, and apelike tendencies in humans (Goode, p. 27). In addition, biological theories of deviance see crime and deviant behavior as a form of illness due to pathological factors to certain individuals. The biological theory is another example of Charles Whitman actions. Smart, strong, and talented, Charles Whitman seemed like a perfect all-American boy stereotype.
