Biological explanations of criminality - GCSE Psychology Wikia Mallick and McCandles found that people were much less aggressive when given a reason for their frustration. 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. Early twin studies e.g. Lange (1929) were inadequately controlled and lacked validity as to whether the twins were monozygotic or dizygotic as it was based on appearance . Its not just an environmental issue (Edwards, 1968). They have evolved ways of warning others to back off: Dogs bark and snarl, cats hiss, apes beat their chest, or wave sticks about. LS23 6AD 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). One strength of the genetic explanation of offending behaviour is that it is based on scientific studies and supported by empirical evidence. adoptees were most likely to offend if both their biological and adoptees parents had a criminal record. Study notes, videos, interactive activities and more! Mears (2013) believed that the code of the street is imported into prison and is the fundamental cause of aggression. One way in which genetics could potentially influence offending behaviour is by causing abnormal monoamine metabolism. The danger is that it justifies deviant behavior: Plenty of people suffer injustice or unfairness and do not turn to violence. Annals of the American Academy of Political and Social Science, 600, 8698. DNA provides instructions for general physical characteristics (e.g., height)and the process that occur within an organism (e.g. Get and keep a better share of resources. The main criterion is that benefits must outweigh costs. [Like a red rag to a bull!]. Priming means that a particular event, image, or even word may be associated with these thoughts. Twin Studies Evaluation - Advantages and disadvantages table in A Level Tends to overlook the effects of socialization and other environmental issues, such as environmental stressors. Desensitisation can be monitored by physical indicators of stress, such as heartbeat and galvanic skin response. Bushman [1998] Participants who had watched a violent film responded more quickly to aggressive words than those who had watched a non-violent film. Females receiving testosterone became more aggressive. 19 Union Square West, New York, NY 10003, United States. Therefore de-individuation need not always lead to aggression, Postmes & Spears (1988): Deindividuated people are not necessarily aggressive Crowds may be happy and good-natured as at pop festivals. New York:Rockefeller University Press. This is aggression between different groups, such as warfare and gangs. Exam Tip: Many criticisms can be made of the methodologies used in studying the link between Media and Aggression. 1 - Genetic explanations of offending behaviour investigate what genes are associated with offending. Supporters seem much more likely to misbehave when their team is losing. Adoption studies attempt to rule this out by looking at children who have been adopted and have therefore been raised by adopted parents where there is no genetic similarity. 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. Dolf Zillman suggested that if we survive the real-life danger, we feel good afterward [winners]. MALE MZ: 35%, MALE DZ: 13% FEMALE MZ: 21%. He found that if the model had a red underside, the stickleback would aggressively display and attack it, but no red meant no aggression. Bushman does not agree with the idea of Catharsis that aggression may lead to more aggression. Humans are certainly capable of developing new ways of expressing aggression such as cyber bullying! That was only one experiment not the whole theory. Males receiving testosterone suppressants became less aggressive. The appropriate conjunction between the words nature and nurture is not versus but and. Damage to the gene in so-called knockout mice raises aggression. A danger is that media violence makes children more desensitized and more hardened to acts of violence in real life. PDF Biological theories of offending - Psychlotron Rissman et al. They suggest that groups or sub-cultures come together because they have some sort of similarity (convergence) and then establish their own norms (emergent norms). Earn points, unlock badges and level up while studying. Prevent a partner from being unfaithful. Dabbs and Morris (1990) Blocked pathways to success study: When a rich boy with high testosterone came home from the army, he was less likely to get into trouble, but when a poor boy with high testosterone came home, he was more likely to get into trouble. Everything you need for your studies in one place. According to Mednick et al. (The cause may be abstract, too powerful, or unavailable.). Christiansen (Eds.) The researchers hypothesised that males in this family had a, 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. So, the level of aggression will depend on the following: Real-world application to explain mass killings Staub suggests that mass killings are often rooted in the frustration caused by social and economic difficulties within a society, leading to aggression against this group Can be applied to the Germans blaming the Jews for the loss of the war and the severe economic problems following it which suggests that widespread frustration, when manipulated by a propaganda machine, can have violent consequences for a scapegoat group. AO3 However criminality is not always the same as aggression. The human is conditioned to think in patterns that have been pre-programmed into the machine. Daly and Wilson: Male Male aggression among young men is common in all human cultures suggesting it is evolutionary. 2. 2023 Springer Nature Switzerland AG. Universal: all the animals in that species use the same type of threat. Christiansen (1977) found MZ concordance rates of 35 per cent, compared with 13 per cent for DZ twins. 1970. Berkowitz thinks watching violent movies could lead to storing schemas and cognitive scripts which involve aggression, e.g., the students in the Stanford Prison experiment had never been in a real prison but they may have had a schema based on movies they had seen. These are both examples of demand characteristics. Others may be jealousy, pain, and loneliness. 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. Mutations in humans can have the same effect (Deneris, 2003). By: Christiansen, 1977 Aim: determine the extent to which genetics may play a role in criminal activity. Support for Irwin and Cressy/importation model, Men who were members of gangs before they went to prison are more likely to be involved in violent offenses whilst in prison. (1976) Studied 1300 American children trick or treating on Halloween. West Yorkshire, Stop procrastinating with our smart planner features. Pinker (1997) states aggression evolved in men to compete for women. Banduras conclusions: Aggression is not inevitable. This is important as many adoptees remain in contact with their biological families or are selectively placed in adoptive families that are similar to their biological ones.

THE PAIRWISE RATE OF CONCORDANCE, WHICH HAS BEEN USED IN ALL THE PREVIOUS CHRIMINOLOGICAL TWIN TWIN STUDIES, IS FOR MONOZYGOTIC (MZ) MALES, 35 PERCENT; FOR DIZYGOTIC (DZ) MALES, 13 PERCENT; FOR MZ FEMALES, 21 PERCENT; AND FOR DZ FEMALES, 8 PERCENT. The general environment becomes dangerous and aggressive. FEMALE DZ: 8% Viewing violence may cause children to develop cognitive scripts which involve violence in dealing with situations. 35:176. E.g. Longitudinal Research in the Behavioral, Social and Medical Sciences, vol 2. Deterministic: Assumes humans have no choice and will follow primitive behavior patterns. Reductionist: Danger of seeing only biological and overlooking social psychology issues such as de-individuation. Zimbardo found that ordinary students became aggressive and cruel when they took on the role of prison guard. 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. 127. Genetic and environmental factors are impossible to isolate McDermott et al. 89. Giving testosterone to newborn female mice made them act like males with increased aggression when later given testosterone as adults. Kety, S.S., D. Rosenthal, P.H. Wolves, Stags, and Lions. Her Majestys Prison Woodhill: Major improvements at this prison included less noise, better ventilation, attractive views, and especially less crowding. This may have been the MAIN reason for aggression, as there was no other property worth fighting over as we evolved. Disinhibition can explain the effect of cartoon violence Children learn social norms through cartoon characters as the aggression they carry out is socially normative, especially when it goes unpunished Children learn that aggression is rewarding and achieves goals in a socially acceptable way, therefore, are more prone to copy it. 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. VAT reg no 816865400. Male and female mice with and without the gene were tested. 2 - One way of studying heritability is by conducting twin studies. This process is experimental and the keywords may be updated as the learning algorithm improves. Comparative much of the work on genes has been done on animals and may not apply to humans so easily. Bohman, M. 1978. Biological explanations of offending behaviour provide strong support for the nature side of the nature versus nurture debate.For example, research into families and twins, suggests that there is some genetic basis for behaviour, which has implications for our understanding of offending behaviour. Refusal to consider genetic factors in crime has had political overtones (Haller, 1968). Females given testosterone as adults did not react in this way, suggesting that testosterone masculinizes aggression systems in the brain at birth. Harris (1974) Found that people at the front of a cue were less aggressive if someone pushed in, whereas people at the back of a long cue felt a greater sense of frustration and, therefore, made a bigger fuss. With these particular questions, there is a sizeable risk that people dont understand the difference between the questions and then write about the wrong thing. Part of Springer Nature. Another situational argument is that the prisons themselves are dysfunctional. Abstract Biosocial Bases of Criminal Behaviour. (1984) Adoption Study Summary. In the late 70s, Karl Christiansen launched a large-scale study of 3,586 twin pairs in Denmark. 1968. For example, sexual jealousy may have evolved to ensure that men pass on their own genes rather than allowing other males access to their mate. Next, we will discuss studies that support genetic explanations of offending behaviour, including the Christiansen (1977 twin study) and Mednick et al. 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. BSc (Hons) Psychology, MRes, PhD, University of Manchester. In 1974, Karl O. Christiansen evaluated the criminal behavior of 3,586 twin pairs born in Denmark between 1881 and 1910. Its 100% free. Christiansen (1977) Aim: To see identical twins would both become criminal Procedure: He looked into the arrest records of over 3,500 twin pairs in Denmark and identified concordance rates of criminal behaviour of monozygotic (identical) twins and dizygotic (non-identical) twins (who share 100% and 50% of their genetic make-up respectively) Behaviorists believe learning occurs through experience followed by either punishment or reward. Biological explanations of criminality - GCSE Psychology Wikia Mallick and McCandles found that people were much less aggressive when given a reason for their frustration.
