Additional criticism can also be noted in the way, “legislators refused to replace a system of penalties with measures of social defense” (Horn 2003, p. 133). Biological Theories of Crime. Why Some Biological Explanations for Deviancy Have Been Discredited Biological Theories. Francis Galton’s theory, which is the eugenics system failed to solve or reduce crime or modify any form of antisocial behavior. The Biology of Deviance Abstract The objective of this writing is to provide careful examination of Adrian Raine’s compilation of biologically theoretical ideas in his book, “The Anatomy of Violence: The Biological Roots of Crime” (2013). The link was demonstrated experimentally in humans by John Mann, Victoria Arango & Mark Underwood (1990) who administered the drug dexfenfluramine to 33 adult males and found that males, but not females, reported greater feelings of hostility and aggression on a post-administration questionnaire. Interestingly, Christian Keysers (2011) found that criminals with psychopathic tendencies only empathised (with a person in a film) when asked to. The table left shows the percentage of sons who have criminal records and whether the biological and adoptive parents also have a criminal record.Â The correlation with having just a biological parent with a criminal record is almost as strong as having both a biological and an adoptive parent with criminal records.Â Michael Bowman (1996) found someÂ similar patterns in Sweden – also shown in the table left – from examining 913 women and 862 men from the Stockholm Adoption Study.Â While the sample sizes of these studies are Â impressiveÂ – especially Mednick, Gabrielli & HutchingsÂ – they are it is still vulnerable to accusations of cultural bias as the sample came from just one smallÂ part of Europe. They found elevated dopamine and reduced serotonin, indicating the ratâs brain chemistry had changed to facilitate the increased aggression required of it. Hermon, Z., Friedman, E., & Rocca, S. (2007). However, a meta-analysis by Angela Scerbo & Adrian Raine (1993) of 29 studies on anti-social children and adults published before 1992 found different results. The West and Russia: a Divergence of Values? In summary, there does seem to be a genetic influence in criminality but studies are contradictory (and sometimes confusing!) Epidemiological evidence that genetic factors contribute to criminal behavior come from three sources: family, twin, and adoption studies. Biological Theory of Crime Biological theories of crime are widely associated with Cesare Lombroso, one of the founding fathers in the discipline of criminology. Again, this could be an epigenetic effect. Robert Plomin (2001) argues that even identical twins are treated differently by their parents and, therefore, environmental factors can confound assumptions about MZ concordance rates. Interesingly tly Cases et al Â found that disabling the MAOA gene on the X chromosome of XY male mice made them highly aggressive – as per the ‘warrior gene’ effect. Cases et all were then able to restore the male mice to ‘normal’ behaviour by restoring the function of the MAOA gene on their X chromosome. Almost inevitably such studies have proved highly contentious, provoking heated debate. New York: Praeger. Prior to Lombroso’s Biological theory of crime, Cesare Beccaria and Jermey Bentham had introduced the Classical School of Crime. Take your favorite fandoms with you and never miss a beat. However, it may not be the lack of serotonin itself which is the key factor but, rather, the consequent increase in the density of serotonin receptors. The first real modern Biological theory of crime was that of Italian army doctor Cesare Lombroso (1876) who considered criminals to be evolutionarily backward. Some biosocial theorists believe that biochemical conditions – including those acquired through diet – can control or influence violent behaviour. As the influence of genes is regulated through various environmental stimuli, it may be that genetic potentiality for âcriminal behaviourâ is inhibited in some by their experiences and facilitated into development in others viaÂ different environmental experiences. The Biological Theory of crime is based on the concept that criminals were born to be criminals biologically. There are a limited number of studies looking at adoption of children from parents with criminal records. For example Lombroso describe an atavistic criminal as one who possesses primitive traits that can be linked to evolutionary times. This study suggests that lower serotonin levels (due to depleted tryptophan) made it more difficult for the prefrontal cortex to regulate the emotional responses generated by the limbic structures. However, some traces still exist. Generally, the thought was that certain physical attributes were passed down from parent to child, making the child more at risk of committing crimes. HistoricallyÂ tryptophan, a serotonin precursor, has been given to juvenile delinquents and unpredictable institutionalised patients to reduce aggressive tendencies, leading Richard Davidson, Katherine Putnam & Christine Larson (2000) to suggest that serotonin may have an inhibitory function. Biological theorists would also endorse stricter penalties and better law enforcement techniques for crime control, but there are several methods of crime control that are specific to the biological theories of criminality. The findings from Donna Miles & Gregory Careyâs (1997) meta-analysis of 24 twin and adoption studies were more in support of Mason & Frick, finding genetic influence accounted for as much of 50% variance in aggression. A Spiral Perspective on Human Development..? From 182 MZ twin pairs and 118 DZ twin pairs – all male – they concluded that genes accounted for more than 40% of individual differences in aggression. Gerald Brown et al (1982) found that the major metabolite of serotonin tends to be low in the cerebrospinal fluid of people who exhibit impulsive or aggressive behaviour. Journal of Research on Crime and Delinquency, 28, 227−251. Charles Goring conducted a statistical study in which he set out to measure the accuracy of Lombeoso’s theory of crime, which was based under the notion of distinct physical differences between criminals and non-criminals. Social factors are a reflection of environmental sources of influence, such as socioeconomic status. For this theory of crime to be plausible, it must make a few simple assumptions about humanity. (Prior to Lombroso, crime and criminal behaviour were the preserve of religious and philosophical debate. There was a significant negative correlation between lesser volume and more anti-social behaviour and less control. Spiral Dynamics Leadership in the Integral Age, MeshWORKS â a 2nd Tier Perspective and Process, Aligning Neurological Levels â a Reassessment, Caregiver Sensitivity vs Temperament Hypothesis, Romantic Relationships: Economic Theories, Maintenance and Breakdown of Relationships, The Often Misunderstood Dynamics of Global Change, The EU: an Organisation divided by Values, Modernisation Theory vs Stratified Democracy. They showed certain ape-like characteristics or sometimes just âsavageâ features. Biological theories. This suggests very much that there is a genetic element in criminality.Â However, the sample sizes were rather small. Only when the Law of Diminished Responsibility is applied in cases of self-defence and mental illness – and in some countries (eg: France) ‘crimes of passion’ (temporary insanity) – is the defendant assumed not to have acted from their own free will. Lombroso’s major break came when he was instructed to perform a post-mortem examination on Guiseppe Villela, who had been imprisoned for theft. and participating in orgies. But a number of factors complicate such a simplistic understanding of crime … Criminology - Criminology - Sociological theories: The largest number of criminological theories have been developed through sociological inquiry.

In other words, some people intentionally seek out aggressive encounters because of the rewarding sensations, caused by the increase in dopamine from these encounters. In P. Cordella and Larry Seigel (Eds. There is also the labelling effect to be considered – that the police are more likely to suspect certain people of having been involved in an incident because they stereotypeÂ people with that build as more likely to be ‘criminal’. The biological theory for crime focuses on the likelihood that an individual will become a criminal. Andreas Reif et al (2009) investigated the relationship between impulsivity and variants of the NOS1 gene, using a sample of psychiatric clinics which included 182 criminals. Contributing to Criminal Justice. While Christiansenâs work is open to criticism – not least because the correlation was for property crimes, not other crimes – generally records of criminal and aggressive behaviour in adult twins show higher concordance rates for MZs. Lombroso’s biological theory of crime: The most vivid example of the biological determinism is the theory of Cesare Lombroso. Her publications include The Crime of All Crimes: Toward a Criminology of Genocide, The Criminal Brain: Understanding Biological Theories of Crime, and, with Michelle Brown, Criminology Goes to the Movies. Therefore, the main backbone elements of crime are personality traits of a potential criminal and the social conditions of life. Surprisingly the results concluded that when relaxed, the length in space between criminals’ toes had an interdigital space of 3mm greater than of that of non-criminals. Such physical anomalies included facial assymmetry, low sloping foreheads, large jaws, high cheek bones, large ears, long arms, thick skulls, dark skin and extra nipples, toes and fingers. Biological theoriesÂ tend to ignore such environmental and psychological factors though they may equally may play a role in explaining such behaviour. The researchers found a consistent trend of lower levels of serotonin in aggressive individuals. Wolfgang Retz et al (2004) looked at the relationship between violent behaviour and the variant gene 5-HTTLPR in 153 men attending psychiatric assessments with respect to criminal behaviour. The terms ‘‘biological’’ and ‘‘genetic’’ are often confused, in part due to the fact … This theory emphasizes punishment as the best means to deter individuals from committing crimes: Make the cost sufficiently outweigh the reward and individuals will decide that crime is not worth it. The effects on areas associated with learning could also mean lower IQ and, therefore, lower chances of employment and a higher risk of turning to criminal behaviour. Pp. Classical and Positivist Views of Behavior. There would be serious ethical concerns with deliberately breeding humans to see if more aggressive humans could be created; but Randy Joe Nelson (2006) has noted that selective breeding experiments can lead to more aggressive behaviour in animals. The terms "biological" and "genetic" are often confused, in part due to the fact that they represent overlapping sources of … Curt Bartol (1999) cautiously advises that mesomorphy may be related to teenage offences but not to adult ones. 65-84). In support of his theory, Cesare Lombroso conducted studies in which he measured the length in space from the first and second toes of criminals. Kirsti Lagerspetz (1979) demonstrated this in mice which she selectively bred over 25 generations. They also found that environmental/family influences lessened and genetic influence increased as people got older. Perhaps shedding some light on paedophilia, Boris Schiffer et al (2007) found male paedophiles had less grey-matter volume than comparison groups of heterosexual and homosexual men. Shortly before his death, Lombroso help his daughter Gina translate the text of Criminal Man for an English speaking audience. The study consisted of young girls viewing images of criminals and non-criminals the objective being to differentiate them based solely on facial features. Interestingly Solms associates the limbic systems with Freudâs impulsive and sometimes violent Id while Caspers et alâs fMRI scans seem to imply the limbic system is associated with the self-expressive vMEMES. The basic concept underlying this theory was that the humans did not act according to God’s will or under the influence of … Yaling Yang et al (2009) compared 27 psychopathic persons with 32 controls, using MRI scans, They found the psychopaths had 17.1% less volume in the left amygdala and 18.9% less volume in the right amygdala. Besides noting the abnormality in physical characteristics within criminals, Lombroso was also intrigue by the difference in writing styles. Genes and neurotransmitters ... Now, the conversation about crime and biological explanations focuses more on the relationship between genetics and crime than the relationship between phenotypic features and crime. The MZ twins had a concordance rate of 77% compared to just 12% of the DZ twins. From a study of more than 4,000 photos of student male physiques and 650 possible personality traits, Sheldon differentiated 3 main somatypes:-. One of the biggest critics of Cesare Lombroso was a prison medical doctor named Charles Goring. Such differences could lead to an increased risk of committing acts of extreme violence. Criminal behavior results from a complex interplay of social and biological factors. The theory primarily pertains to formal deviance, using biological reasons to explain criminality, though it can certainly extend to informal deviance. (Raineâs technique involved watching a screen for 32 minutes and responding every time a zero appeared – with the impulsive individuals missing many of the zeros. Biological theories of crime are different from classical theories, shifting the focus from the explanation of rational individuals to irrational and uncontrollable human behavior. Lombroso's Theory of Crime. Â Niels Birbaumer et al (2005) also found reduced amygdala activity in psychopaths undertaking a conditioning task, suggesting little fear or emotional response. Thus, particular types of criminals could be identified by the presence of certain features. LEARNING OUTLINE: The • Defi The • Descr 3.
