Aggression is a result of frustration. We have learned that in a hotel restaurant, we sit down and wait to be served, but in a burger bar, we line up at the counter. Fig. Twin studies compare how similar monozygotic and dizygotic twins are on a particular trait. Plomin, R., & Asbury, K. (2005). It looks at aggression as caused by a biological abnormality and doesn't necessarily acknowledge how this may interact with the environment and what other social and environmental factors are related to offending behaviour. 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. (1984) investigated the heritability of offending behaviour using an adoption study design. Low levels of serotonin result in reduced self-control and increased aggression. Mears (2013) believed that the code of the street is imported into prison and is the fundamental cause of aggression. True or False: Grove (1990) found significant negative correlations between genetic influences and symptoms of antisocial behaviour in twins reared apart. (1993) conducted an analysis of a large family in the Netherlands, a number of which had been responsible for various counts of anti-social and criminal behaviour including attempted rape, exhibitionism and arson. Male and female mice with and without the gene were tested. Biological Theories of Crime - Criminal Justice Often one person or a few people will behave in a certain way that others like so they copy. Active way: Temperament can also impact the person's choices for themselves. 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. Much of the evidence is only correlational and may not prove causation. Milgram believed that people are loyal to the hierarchy of the organization, but sometimes the hierarchy encourages cruel behavior. Case studies are uniquely specific to the small number of individuals involved and therefore lack representativeness. Some characters, and some types of behavior, are more likely to be copied because they are seen as attractive and appropriate, etc. Poole and Regoli 1983: Violence before the prison was the best indicator of violence inside prison. However, the correlations are low to moderate, even though the twins shared 100% of the same genes; this again indicates a significant contribution of environmental factors as well. Everything you need for your studies in one place. Females receiving testosterone became more aggressive. Procedure: Christiansen studied 85 mz (monozygotic twins) and 147 same sex dz (dizygotic) pairs that had lived paste the age of 15. Official websites use .gov Gen Psychiatry. First, we will provide a. Rude words and hand signs can change, so not evolutionary. Normally, we act in certain ways because we have been socialized to know what is right and wrong. Wolves, Stags, and Lions. 3 - Mednick et al. 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. Brunner et al.s (1993) research has been criticised for using a case study method. This is aggression between different groups, such as warfare and gangs. Christiansen (1977) examined over 3,500 twin pairs in Denmark and identified concordance rates of criminal behaviour. 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. 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. 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). Christiansen (1977) found MZ concordance rates of 35 per cent, compared with 13 per cent for DZ twins. It, therefore, contends that events and media images can stimulate related thoughts in the minds of audience members. Gen. Psychiatry. Blumer 1939: Circular reaction where the people add to the crowd, and the crowd fires up the people. Desensitisation can be monitored by physical indicators of stress, such as heartbeat and galvanic skin response. Once triggered, the FAP always ran its course to completion without any further stimulus. However, control females given testosterone as adults did not react in this way (Edwards,1968). These low rates indicate that biological factors are less important than we may suspect and environmental factors are more important than we first thought. The water level gradually fills up till you flush it then it has to be filled up again. https://doi.org/10.1177/0002716205277184, Reif, A., Rsler, M., Freitag, C. et al. Ethics and Gender: Critics feel this theory could be used to justify violence against women. Lea [1984] analyzed FAPs and identified five features: Tinbergen presented male sticklebacks with a series of wooden models of different shapes. These are both examples of demand characteristics. Research support for the role of serotonin Berman et al. Genetics are involved in causing neural vulnerabilities to violence and aggression. Christiansen (Eds.) The results could be due to social learning since the twin sets and families concerned are all occupying the same environment. Others may include feeling uncomfortable [eg. You MUST revise everything because the exam board could choose any question. Edited by Sarnoff A. Mednick and Karl O. Christiansen. Fig. Berkowitz (1989 ) updated version is known as Negative affect theory. Frustration is just one factor. The Phineas Gage study provides evidence that brain damage may have an effect on personality, including aggression. Aim: To see identical twins would both become criminal Atkin [2003] found that priming was more pronounced when the media was more realistic. 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. In January 2012, there was a short question (4 marks) that just said; Describe one experiment which investigated Institutional Aggression. New York:Gardner Press. Heredity & Environment: Are environmental factors a greater cause of aggression? criminality- twin studies (Christiansen 1977) Term 1 / 2 procedure Click the card to flip Definition 1 / 2 studied 3586 pairs of twins in Denmark identical twins= monozygotic twins non-identical twins= fraternal or dizygotic twins Click the card to flip Flashcards Learn Test Match Created by Jpicko98 Terms in this set (2) procedure The MAOA gene controls dopamine and serotonin and links to aggressive behaviour. That was only one experiment not the whole theory. 's (1984) adoption study. Springer, Dordrecht. Deterministic: Assumes humans have no choice and will follow primitive behavior patterns. Huge implications for society -provides the key to understanding the causes of good and bad behavior. By examining monozygotic (identical) twins and dizygotic (non-identical) twins (who share 100% and 50% of their genetic make-up respectively), concordance rates (i.e. The fearlessness Theory: Stress, caused by the hormone cortisol, may inhibit aggression through fear. New York:Gardner Press. [Linz 1989]. Will you pass the quiz? 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. During an action movie, we feel excited and stimulated. Women are less likely to be victims of domestic violence if they have several brothers in town, so aggression can be controlled. . One genetic abnormality affecting serotonin metabolism is the MAOA gene. Some of the most promising work involves the study of twins and adoptees. This was supported by a decreased concentration of 5-HIAA (a serotonin metabolite) in the participants' urine samples. Family studies are another way of investigating genetic links in offending behaviour. This is the same as happens when engaged in real acts of violence. A schema is a model of what we think normally happens. How do adoption studies investigate heritability? These results indicate similarity in terms of antisocial behaviour among the twins. It appeared to suggest that emotional areas of the cortex are to some extent switched off during the game, perhaps an adaptive mechanism that permits an animal to focus on survival. DNA provides instructions for general physical characteristics (e.g., height)and the process that occur within an organism (e.g. 1977a. Tihonen et al. (1984)study? Adverse childhood experiences were found to affect violence only in individuals with a shorter version of this gene (Reif et al., 2007). (1983). Some institutions have harsh living conditions, such as prisons, army camps, and refugee camps This is less of a problem if the deprivation is for a good reason; if you were on a round the world yacht race or a mountaineering trip you have positive attitudes to keep you going. Christiansen, K.O. PDF Biological theories of offending - Psychlotron 1 - Genetic explanations of offending behaviour investigate what genes are associated with offending. To gain marks for criticizing the studys methodologies, the criticism must be contextualized: i.e., say why this is a problem in this particular study. The central idea of social learning theory is that people do not need rewards to learn aggression, they may copy the behavior of others, but this is less likely if they see the other people being punished. This helps us to see if there is any genetic link, in spite of the shared environment. These may be live models, such as parents, or symbolic models, such as characters in the media. This deprivation causes stress and frustration, which leads to an aggressive sub-culture. 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). Displaced Aggression [Dollard 1939] You cant kick the boss, so you kick the cat. Like Lornez, Dollard thought that getting aggressive cleared the mind of frustrations [a Catharsis], and life could then go on as normal. A NUMBER OF DIFFERENT CRIMINOGRAPHIC INDICES ARE COMPARED, SUCH AS TYPE OF OFFENSE, SERIOUSNESS OF SANCTION, NUMBER OF SANCTIONS, MAXIMUM PENALTY, AND CRIMINAL CAREER. 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. Exam Tip: If the question asks about Social Learning Theory, it is not enough only to write about the Bobo Doll experiment. What were the findings of Christiansen (1977) twin study? 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 . Karl Christiansen's (1977) found that of 3586 twins, 35% of male MZ twins; 13% of DZ twins and 21% of female MZ twins ; 8% of DZ twins committed crime (Google Books.2017).Advantages of this study is that there was a large sample of twins used compared to other twin studies. GENETIC EXPLANATIONS OF OFFENDING BEHAVIOUR (Twin Studies - Coggle Breland and Breland found that animals tend to revert to instinctive behavior regardless of training. 298 + index. 89. Make sure you know which is which. Comparative much of the work on hormones and neurotransmitters have been done on animals and may not apply to humans so easily. Contagion Theory : Starting point for deindividuation, Gergen 1973: Deindividuated persons in dark areas became more affectionate. Another situational argument is that the prisons themselves are dysfunctional. Five psychological theories could be mentioned to support the view that repeated exposure to video game violence may lead to real-life aggression: Everything you have ever learned about Operant Conditioning can be beautifully applied to this argument. The importation model does not really explain why some organizations act aggressively when they are made up of good people who are supposed to act sensibly. 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. 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. Some even used the prisoners as slave labor on prison farms. (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. This could transfer to seeking violence in real life. 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. Neuropsychopharmacol 32, 23752383 (2007). By studying identical twins reared apart, Grove (1990) wanted to investigate if their similarities remain even if they don't share their environment. neurotransmitter activity. 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. Universal: all the animals in that species use the same type of threat. It could be argued that some behaviors are learned in the environment but maybe not all. Preliminary Study of Criminality Among Twins (From Biosocial Bases of Monoamines include many neurotransmitters that facilitate communication between brain areas. They also have certain learned patterns of behavior The code of the Streets.. One strength of the genetic explanation of offending behaviour is that it is based on scientific studies and supported by empirical evidence. Christiansen, K.O. Individuals with elevated testosterone levels exhibit signs of aggression but rarely commit aggressive acts, suggesting that social and cognitive factors play a mediating role (Higley et al., 1996). One genetic abnormality affecting serotonin metabolism is the MAOA gene. Mistakes are instantly punished. The aim of the study was to investigate the heritability of criminal behaviour. Genetic Explanations of Offending Behaviour | Psychology | tutor2u This model brings together elements of Social learning and Cognitive Priming Theory and suggests that if we live in a violent environment such as a war zone, we will adapt to it; our thoughts, feelings, and actions will be based around violence, and that is how we will survive. Freud wrote about the build-up of sexual energy [Libido], and Lorenz applied a similar idea here. Test your knowledge with gamified quizzes. 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). Disinhibition explains that watching or playing violent media may change the standards of what is considered acceptable behavior. Most evidence linking low levels of serotonin and aggression is only correlational and does not indicate causality. Neural explanations describe behaviour in terms of abnormalities within the brain and the nervous system. The greater the number of people tended to correlate with the level of violence. (1976) Studied 1300 American children trick or treating on Halloween. 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. Ethology is where we learn about human psychology from studying other animals. Crowe, R. 1975. 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 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. The heritability of offending behaviour is supported by Christiansen's (1977) and Grove's (1990) twin studies and Mednick et al. 214 High Street, Supporters seem much more likely to misbehave when their team is losing. A cognitive script is a way of dealing with a situation. If so, the implications for our justice system can be quite severe, so it's important to assess the different genetic explanations of offending behaviour to truly explore what makes a criminal. To fulfil this aim, he conducted a study of twins who have been separated shortly after birth and grew up in different environments. Reductionist: Is this an over-simplification? 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. Creatures have evolved an instinctive response to certain signs. Tel: +44 0844 800 0085. 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.. date published. Innate: all the animals in that species seem to be born with it and dont have to learn it. 2. Set individual study goals and earn points reaching them. One way of studying heritability is by conducting twin studies. what christiansen was trying to find out he analysed pairs of twins in an effort to determine whether criminal tendencies might be inherited study - procedures monozygotic ( identical) twins where used as they share the same genes as they both developed from the same egg therefore if 1 twin is criminal, so should the other one However, we cannot rule out environmental factors. This theory fails to explain premeditated aggression and bearing grudges. Sign up to highlight and take notes. Zelli [1995] found that cognitive priming could be used to make people suspicious of the intentions of others. Getting a tough reputation is very important in order to get respect and not be a victim. [Like a red rag to a bull!]. Cause and effect Berkowitz argued that frustration is just one of many stimuli that cause negative feelings. Twin studies are a well known method for identifying a genetic basis of behaviour. Evolutionary Explanations of Human Aggression. There is a genetic link to criminal behaviour, but it is not entirely genetic. Irwin and Cressy 1962: People who are sent to prison already have well-established criminal behavior patterns. Twin studies - Christiansen (1977) Identical twins share all of their genes in common and non-identical twins have half of their genes in common. The selection component analysis, which as an essential device makes use of genotypic mother . Prestige, Class and Mobility. (Alcohol and/or drug abuse can be an expression of either a or b.) Presentation: How close, live, and immediate the violence was, Warmth: If the model was more friendly toward the subject. Strength RWA We can show more non-aggressive models and promote more prosocial behavior that is rewarded in the media. 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. Those under 15 were excluded. Stereotyped: behavior follows a certain pattern each time. 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). 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). Zimbardos experiment strongly supports the situational approach. Christiansen et al (1977) 5 terms emma_reed1709 WJEC Criminology, Unit 2, Twin Studies - Biol 6 terms emily_plested Psychological Explanations: Eysenck's Theory 10 terms Images charlotte_scollon Sets found in the same folder Types of Aggression 2 terms jack_squires3 1. Miller. That being said, those who had previously agreed with the concept of atavistic form, later retracted that assertion, but did go on to say that while it may not account for the whole criminal population, it could explain as much as a third of it (Lombroso-Ferrero, 1911). 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. The aim of the study was to investigate the heritability of criminal behaviour. Autism is caused by poor parenting, particularly by 'frigid mothers who reject their children. When we encounter the trigger, we may respond in the way we have been primed. Svalastoga, K. 1959. Here the institutional aggression was on the part of the guards rather than 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. In the late 70s, Karl Christiansen launched a large-scale study of 3,586 twin pairs in Denmark. If the geese survive, then the gene which led to that aggressive response will be passed on.

The controversy may also reflect the fact that, until recently, the evidence for genetic influences consisted mainly of twin studies, some of which were methodologically questionable.
