Much of the evidence is only correlational and may not prove causation. (1976) Studied 1300 American children trick or treating on Halloween. MALE MZ: 35%, MALE DZ: 13% FEMALE MZ: 21%. This was used most frequently in order to explain the cause of crime through genetic reasoning. However, Berkowitz addressed these inadequacies by developing his negative affect theory. Genetics. One way in which genetics could potentially influence offending behaviour is by causing abnormal monoamine metabolism. The central idea of this theory is that humans have a natural tendency to be aggressive if they think they can get away with it. Heredity & Environment: Are environmental factors a greater cause of aggression? Christiansen (1977) examined over 3,500 twin pairs in Denmark and identified concordance rates of criminal behaviour. The experiment was in a lab which may lack ecological validity. Plomin and Asbury (2005) conducted a review that highlighted that, just as environmental research needs to consider the influence of genetics, genetics research needs to consider the role of the environment. Christies, N., J. Andenaes, and S. Skerbaekk. THESE DIFFERENCES ARE ANALYZED IN TERMS OF HEREDITARY FACTORS INTERACTING WITH SOCIAL ENVIRONMENTS THAT PROVIDE DISTINCTIVE PATTERNS AND DEGREES OF RESISTANCE TO DEVIANT BEHAVIOR. If the role of biochemistry can be understood, it can then be treated and managed But it is unethical to give drugs to humans to alleviate aggression as it could lead to social control This could be treated more ethically through diet and exercise which acts on neural mechanisms. What were the findings of Christiansen (1977) twin study? Fig. Canadian Journal of Counselling and Psychotherapy, 14(3).Retrieved from https . Deny own resources to children of rivals, To prevent other males from sharing the prime females. Brunner et al. Just because a trait is highly heritable in the population doesn't necessarily mean we can predict how much genes influence a trait in any specific individual. Bohman, M. 1978. The researchers found that the males had a genetic condition which became later known as Brunner syndrome (it is important to note that females only carry this condition, as it only affects the MAOA production gene on the single X chromosome in males). Gen. Psychiatry. Stop procrastinating with our smart planner features. Effects may involve a reduction in physiological arousal (e.g., heart rate) when exposed to real violence or a psychological response (e.g., having less sympathy for a victim). Then, we will outline how genetics link to neural explanations of offending behaviour. IN ORDER TO EVALUATE THE INFLUENCE OF BACKGROUND FACTORS ON THE CONCORDANCE RATES IN VARIOUS SUBGROUPS OF TWINS, IT IS NECESSARY TO COMPARE THE CONCORDANT PAIRS WITH THE TOTAL TWIN POPULATION WHEN THE TRAIT OCCURS WITH A RELATIVELY HIGH FREQUENCY, AS IS THE CASE WITH CRIME. Wright and Klee (1999): Societies will be more stable and peaceful if they have systems that allow clever or hardworking people to rise to the top. neurotransmitter activity), which can affect psychological traits. For example, if we have often seen clowns throwing custard pies at one another, then when we encounter a custard pie in real life, we may think about throwing it at someone. Animal studies show instinctive patterns of behavior, including aggressive behavior. The situational approach: prisons make people aggressive its the situation to blame. The General Aggression Model [Anderson and Dill]. Male sticklebacks will respond aggressively to the red underbelly of a rival male but not to a female who does not have the red underbelly. Therefore, the violence the children witnessed was on television and was against a doll, not a human. But 30 years ago parents, especially mothers, were blamed for their childrens autism. (2002): Interaction of MAOA problem AND abusive childhood led to aggression. We assume that our parents will feed us and our friends will be pleased to see us because that is what normally happens. Bandura states children learn by imitation and are more likely to copy depending on the following: Bobo Doll experiments: Children copied adults. E.g., Lack of self-control Delisi (2011); Impulsive, anti-social Wang & Diamond (2003). Christiansen found higher concordance rates of criminal behaviour among monozygotic twin pairs compared to dizygotic twin pairs. OF THE TWINS STUDIED, 926 BELONGING TO 799 PAIRS WERE FOUND IN ONE OR BOTH OF THE REGISTERS FOR CRIME WHICH WERE SURVEYED. The aim of the study was to investigate the heritability . Children learn aggressive behaviors through observing aggressive models. We call that a trigger. The researchers studied the cells of affected males and found negligible amounts of MAO-A activity, which indicated that the metabolism of monoamines in this population was abnormal. Kety, S.S., D. Rosenthal, P.H. Especially those involving violence, especially first-person shoot-em-ups, Grand Theft Auto is a very good example. Another situational argument is that the prisons themselves are dysfunctional. Bandura (1973) Frustration may lead to aggression if that has worked for someone in the past and they have internalized that way of dealing with problems. 1977 length. Violent films led to increased activity in those areas which deal with emotion, arousal, and attention not surprisingly but also in the areas used to store episodic memory. Google Scholar Vger D., Leon D.Ischaemic heart disease and low birth weight: a test of the fetal-origins hypothesis from the Swedish Twin Registry. Brunner (1993) looked at a very large Dutch family with 28 males who had a history of rape, violence, and impulsive aggression associated with low levels of the MAOA gene. of the users don't pass the Genetic Explanations of Offending Behaviour quiz! One way in which genetics could potentially influence offending behaviour is by causing abnormal monoamine metabolism. The participants had a rare genetic condition, which only affects males and manifests as an inability to control aggressive behaviours. This could be more effective in certain types of people [not very intelligent, have no positive role model, feel hard done by in life]. Grove (1990) also wanted to investigate the genetic contribution to offending behaviour. Participants were subjected to a functional magnetic resonance imaging scan whilst playing a violent video game. Christiansen (Eds.) The desensitization argument suggests that if children watch too much violence on TV, they will be less scared and, therefore, more open to aggressive activity. Zelli [1995] found that cognitive priming could be used to make people suspicious of the intentions of others. In:S.A. Mednick and K.O. Monoamines include many neurotransmitters that facilitate communication between brain areas. Delisi (2004) found that gang members were NOT more violent than other prisoners. In the natural world, a certain level of natural fear should make people hold back from violent situations. Fig. Scandanavian Studies in Criminology. He defined psychopathy as follows: 1. These results indicate similarity in terms of antisocial behaviour among the twins. By: Christiansen, 1977 Aim: determine the extent to which genetics may play a role in criminal activity. (1984) adoption study summary. where researchers have access to extensive data on over 3,500 twin pairs. Karl O. Christiansen evaluated the criminal behavior of 3,586 twin pairs born in Denmark between 1881 and 1910. BMJ 2006;333 (7578):1095. How does genetics affect criminal behaviour? Prestige, Class and Mobility. Genes consist of DNA (deoxyribonucleic acid) strands. 345. This paper performs a critical review of twin and adoption studies looking at possible genetic factors in criminal and antisocial behavior. One strength of the genetic explanation of offending behaviour is that it is based on scientific studies and supported by empirical evidence. This suggests that testosterone masculinizes androgen-sensitive neural circuits underlying aggression in the brain. Similarity: boys will copy boys, family links and groups, etc. The serotonin deficiency hypothesis states that decreased serotonin disturbs the OFC and, therefore, reduces the inhibitory effect (of normal serotonin levels) with the consequence that individuals are less able to control impulsive and aggressive behavior. The twins were assessed through tests and interviews in terms of alcohol problems, drug problems and symptoms related to antisocial behaviour in childhood and adulthood. (Gardner Press, New York, 1977.) Buss himself always points out that we are not controlled by our genes; we have inherited the ability to learn and to choose. Frustration is any event or stimulus that prevents an individual from attaining a goal and its accompanying reinforcement quality (Dollard & Miller, 1939). ], Cognitive Priming: What connects to what in the brain [Berkowitz, Huesmann], Cognitive Scripts: A pattern of behavior we have ready to deal with certain situations. What are biological explanations of offending behaviour? B.A., History and Educational Psychology, University of Exeter. Here the institutional aggression was on the part of the guards rather than the prisoners. Why were the males studied by Brunner et al. Brunner et al.s (1993) research has been criticised for using a case study method. Some people retreat, back down, and hide in their cells. These twins were then cheked against Danish police records. Create flashcards in notes completely automatically. The number of hospitalizations in the previous 18 years was obtained through register linkage, thereby obtaining health information on 96% of the study population, including all . Drury and Delisi (2011). Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in Viewing violence may cause children to develop cognitive scripts which involve violence in dealing with situations. Twin studies have shown that twins have similar levels of aggression. Genetic Explanations of Offending Behaviour. Zimbardos experiment strongly supports the situational approach. Twin Studies . Individuals model aggressive acts in the game. Females receiving testosterone became more aggressive. THE PROBABILITY OF CRIME INCREASE FOR A TWIN WHOSE PARTNER IS CRIMINAL AS COMPARED TO THE GENERAL CRIME RATE OF THE TWIN GROUP IS CALLED THE 'TWIN COEFFICIENT.' [Linz 1989]. Genetic and environmental factors are impossible to isolate McDermott et al. A very good example would be the hippy culture of the 1960s. Mutations in humans can have the same effect (Deneris, 2003). Individual factors [Collins 1989] make disinhibition more or less likely: Disinhibition is less likely if Strong family norms against violence or when adults discuss issues from the film with their children. This was supported by a decreased concentration of 5-HIAA (a serotonin metabolite) in the participants' urine samples. The media gives aggressive behavior social approval, especially where effects on victims are minimized and appear justified. Behaviorists believe learning occurs through experience followed by either punishment or reward. 1 - Genetic explanations of offending behaviour investigate what genes are associated with offending. An official website of the United States government, Department of Justice. BSc (Hons) Psychology, MRes, PhD, University of Manchester. Genetic factors do not work in isolation but interact with environmental factors as well. Supports deindividuation theory. The MAOA gene codes for the production of the enzyme MAOA, involved in breaking down neurotransmitters in the synapse, especially serotonin. Lorenz said that all creatures build up a reservoir of Action Specific Energy you could call it pent-up aggression. When the Innate releasing mechanisms [IRM] trigger the Fixed Action Pattern [FAP] all the aggression is fired off. The conclusion here is that individuals can inherit genetic conditions which make them prone to offending behaviour. (Plomin & Asbury, 2005, p.86). Christiansen (1977) found MZ concordance rates of 35 per cent, compared with 13 per cent for DZ twins. Research support for disinhibition Berkowitz found that participants who saw a film depicting aggression as vengeance gave more fake electric shocks to a confederate The media disinhibited aggression by presenting it as justified and removing social constraints. One strength of the genetic explanation of offending behaviour is that it is based on scientific studies and supported by empirical evidence. percentages to show how many twin pairs share the behaviour under observation) can help to indicate a possible genetic tendency. (2008) established that variations in male testosterone levels are inherited and, therefore, genetic. Lorenz observed that most intra-species aggression consisted mainly of ritualistic signaling (e.g., displaying teeth) and rarely became physical. Bushman does not agree with the idea of Catharsis that aggression may lead to more aggression. Christiansen (1977) examined over 3,500 twin pairs in Denmark and identified concordance rates of criminal behaviour as follows: The findings are interesting as they indicate a degree of inheritance; however, there are some key points to consider. By registering you get free access to our website and app (available on desktop AND mobile) which will help you to super-charge your learning process. To see off predators: For example, a group of hissing geese can drive off a fox, even though the fox would probably win a straight fight. Research shows a correlation between serotonin and aggression risks oversimplifying the true mechanisms involved as other factors which influence or even cause aggression is overlooked The neural and hormonal regulation of aggression is almost certainly more complex than our current understanding. Some characters, and some types of behavior, are more likely to be copied because they are seen as attractive and appropriate, etc. Lea [1984] analyzed FAPs and identified five features: Tinbergen presented male sticklebacks with a series of wooden models of different shapes. This could transfer to seeking violence in real life. Research support for anonymity Zimbardo found that when asking females to elicit electric shocks to each other, more severe shocks were given in the deindividuated condition (participants wore hoods that hid their faces) than in the controlled condition (participants were introduced to each other and wore nametags) There is support for anonymity as a factor of de-individuation, causing aggression. Neural Explanations of Offending Behaviour. Brown (2001) holidaymakers became more aggressive when frustrated by delays. Twin studies - Christiansen (1977) Identical twins share all of their genes in common and non-identical twins have half of their genes in common. Universal: all the animals in that species use the same type of threat. Let's consider the example of the MAOA gene; while a shorter variation of this gene is independently linked to violent behaviour, it can also interact with one's nurture. Exam Tip: If the question asks about Social Learning Theory, it is not enough only to write about the Bobo Doll experiment. Poole and Regoli 1983: Violence before the prison was the best indicator of violence inside prison. 1970. Festinger (1952) invented the term Deindividuation, defined by Fraser and Burchell (2001) as A process whereby normal constraints on behavior are weakened as persons lose their sense of individuality.. He found that if the model had a red underside, the stickleback would aggressively display and attack it, but no red meant no aggression. Once triggered, the FAP always ran its course to completion without any further stimulus. Genes consist of DNA strands. (2014) genetic analysis of nearly 900 offenders revealed abnormalities in two genes associated with a violent crime: Genes can also influence behaviour indirectly through one's environment. Socially sensitive It suggests that aggression is somewhat excusable and out of the control of the individual committing the behavior This has important consequences within the legal system Brings into question the credibility of the theory and makes it imperative that such socially sensitive research is not released into the public domain. A consistent pattern, lasting beyond 19 years of age, of im- pulse-ridden or acting-out behavior must be evident. fitness & diet camp. Appropriateness: If the behavior was appropriate. Adoption studies A key criticism raised by research into genetics is that it cannot rule out the effect of the environment. But could over-exposure to gaming have the same effects? Christiansen, K.O. Milgram believed that people are loyal to the hierarchy of the organization, but sometimes the hierarchy encourages cruel behavior. They screened 14,427 Danish adoptees to see if they had at least one court conviction and looked at whether their adoptive or biological parents also had any convictions. Study notes, videos, interactive activities and more! [1979] found that watching violent sports did not flush aggression out of the system but tended to increase it. Priming means that a particular event, image, or even word may be associated with these thoughts. The main criterion is that benefits must outweigh costs. Some even used the prisoners as slave labor on prison farms. Mullen (1986) studied lynch mobs. Neural explanations describe behaviour in terms of abnormalities within the brain and the nervous system. Copenhagen:Gyldendal. One genetic abnormality affecting serotonin metabolism is the MAOA gene. Moreover, the MAOA gene has been linked to impaired control of aggression. Adoption studies look at how similar the adoptees are to their biological versus adoptive families. Its a dispositional approach because everything depends on the attitudes of the prisoners. It was found that if a biological mother had a criminal record, 50% of the adopted children also had one by the time they were 18. The condition results in lower intelligence levels (the family studied had an average IQ of 85) and causes a deficiency in monoamine oxidase A (MAOA), an enzyme responsible for the metabolism of neurotransmitters such as serotonin (which has links to aggression). But this only applies to places with harsh conditions: E.g., in prisons, the army, refugee camps, etc. Exam tip the Brunner study can be used as an example of both genetic and neural explanations, as both explanations can be used to justify the conclusions drawn by the researchers. 1968. The appropriate conjunction between the words nature and nurture is not versus but and. Children observe aggressive behavior in others, but how they act may depend on what the consequences of aggression are, particularly for those they use as role models. Deiner et al. Giving the hormone testosterone to newborn female mice made them act like males with increased aggression when given testosterone as adults. Cause and effect Berkowitz argued that frustration is just one of many stimuli that cause negative feelings. Oxford:Pergamon. However, supporters of the nurture argument argue that to ignore the influence of external factors such as parenting, culture and social learning, misses crucial elements of explaining offending behaviour and it can therefore be considered reductionist.This is important to consider as while the evidence to support a biological basis for offending behaviour is strong, there are other elements to consider which reduce the effectiveness of the biological findings. This argues against de-individuation and the faceless crowd. Plomin, R., & Asbury, K. (2005). It does not imply aggression will result. Biosocial Bases of Criminal Behavior. General criticisms and/or strengths of theories and studies.E.g., Banduras Bobo Doll studies are laboratory experiments and therefore criticizable on the grounds of lacking ecological validity.. Upload unlimited documents and save them online. Genetic explanations investigate the heritability and genetic correlates of offending behaviour. (1984) showed that adoptees (sons) are more likely to offend if their biological father has a criminal record. Cannot generalize to humans We should be cautious about making such generalizations, especially to complex behavior like aggression, because humans can act upon free will, unlike animals Human aggression is extremely destructive, but we seem to have an element of control (our processing might not be automatic/innate) Aggression cannot truly be measured in animals because the intent is not known and cannot be communicated (may be an act of survival, not aggression). I am primed to respond differently to the cricket ball. Annals of the American Academy of Political and Social Science, 600, 8698. These low rates indicate that biological factors are less important than we may suspect and environmental factors are more important than we first thought. Others may include feeling uncomfortable [eg. THE TWIN COEFFICIENT IS EXAMINED IN RELATION TO CERTAIN CHARACTERISTICS OF THE POPULATION GROUP TO WHICH THE TWINS BELONG, AND IT IS DEMONSTRATED THAT THE SPECIFIC TWIN MILIEU, WHICH IS A PRODUCT OF INHERITANCE AND ENVIRONMENT, HAS DIFFERING INFLUENCES ON MZ AND DZ TWINS PAIRS AS WELL AS ON PAIRS WITH VARYING ENVIRONMENTAL BACKGROUNDS. The genetic explanation of offending behaviour can be considered to be biologically reductionistic. https://doi.org/10.1038/sj.npp.1301359. If both identical twins are criminal this suggests a very strong link to criminality. This would support the FAP theory. There is a genetic link to criminal behaviour, but it is not entirely genetic. Offending behaviour refers to actions which are against the law. This may also apply to other groups and institutions; The army / Extreme political groups, / Street gangs. This strongly argues for the importation model, not the deprivation model. Berkowitz (1989 ) updated version is known as Negative affect theory. Frustration is just one factor. Over 10 million students from across the world are already learning smarter. Cosmides and Tooby, the Military Contract: Men will only fight if those who share the rewards also share the danger. This may have been the MAIN reason for aggression, as there was no other property worth fighting over as we evolved. A cognitive script is a way of dealing with a situation. Male and female mice with and without the gene were tested. The human is conditioned to think in patterns that have been pre-programmed into the machine. So individuals with lower levels of cortisol are less inhibited, more inclined to take risks, and act impulsively (Raine, 2002). Monozygotic twins are not only identical when it comes to their genes, but also share a similar environment growing up. Ethics and Gender: Critics feel this theory could be used to justify violence against women. Genetics are involved in causing neural vulnerabilities to violence and aggression. (1983). Deterministic: Evolutionary explanations may seem to suggest that aggression is natural, but Figuerdo [1995] suggests jealousy and domestic violence are context-specific, not inherent. They also have certain learned patterns of behavior The code of the Streets.. These keywords were added by machine and not by the authors. Crowe (1972) compared a group of adopted children whose biological mother had a criminal record, to a control group of adopted children whose biological mother did not have a criminal record. Features of dysfunctional Power Systems (Zimbardo). Biosocial Bases of Criminal Behavior. E.g., Fertile young women 10 times at risk of domestic violence. PubMedGoogle Scholar, Social Science Research Institute, University of Southern California, USA, Katherine Teilmann Van Dusen&Sarnoff A. Mednick&, Mednick, S.A., Gabrielli, W.F., Hutchings, B. When people are frustrated, they experience a drive (links to the psychodynamic approach) to be aggressive towards the object of their frustration, but this is often impossible or inappropriate, so the source of their aggression is displaced on something or someone else. Genetic Influences in Criminal Behavior:Evidence from an Adoption Cohort. This, in turn, led the people who had been primed to act in a more aggressive manner. A danger is that media violence makes children more desensitized and more hardened to acts of violence in real life. WHILE IT IS NOTED THAT CONCORDANCE RESULTS CAN BE NONCOMPARABLE DUE TO CHANGES IN THE PENAL CODE OVER THE YEARS, AS WELL AS IN THE ADMINISTRATION OF JUSTICE, IT IS CONCLUDED THAT NO RADICAL CHANGES TOOK PLACE DURING THE PERIOD COVERED BY THIS STUDY IN DENMARK. Social Cognitive Observational Learning Theory [an updated version of Bandura]. [2004] 35 studies examined Holst [1954] found that instead of getting it out of the system, aggressive action could feed back to make the person angrier and increasingly more aggressive. Twin studies compare how similar monozygotic and dizygotic twins are on a particular trait. Boston Spa, Gillingham, D. E. (2012). Acts of impulsive aggression, such as domestic violence, have a genetic link to the serotonergic system, suggesting that many genes may be involved in aggression (New et al., 2003). Anderson and Dill [2000] Found that playing a violent computer game led to more aggressive thoughts. Prospective Studies of Crime and Delinquency pp 3956Cite as, Part of the Longitudinal Research in the Behavioral, Social and Medical Sciences book series (LRBS,volume 2). (1993) conducted a family study to investigate the effect of the MAOA gene on behaviour. Comparative much of the work on hormones and neurotransmitters have been done on animals and may not apply to humans so easily. These ideas can be used as criticisms of de-individuation.
