Theories of criminal behaviour Biological: Physiological Lombroso in 1876 argued that the criminal is a separate species, a species that is between modern and primitive humans. He argued that the physical shape of the head and face determined the "born criminal". These people were primitive and were unable to adapt to modern morality. His view was based on genetics. The atavist (primitive genetic form) and had large jaws, high cheek bones, large ears, extra nipples, toes or fingers, and were insensitive to pain. Lombroso went further and suggested that from the surveys he had carried out in prison, he could detect physiological differences between different types of criminal. Thus, murderers were said to have: Cold, glassy, blood-shot eyes, curly, abundant hair, strong jaws, long ears and thin lips Whilst sex offenders have: Glinting eyes, strong jaws, thick lips, lots of hair and projecting ears.' William Sheldon believed that people could be classified into three body shapes, which correspond with three different personality types. 1. endomorphic (fat and soft) tend to be sociable and relaxed. 2. ectomorphic (thin and fragile) are introverted and restrained 3. mesomorphic (muscular and hard) tend to be aggressive and adventurous. Sheldon, using a correlational study, found that many convicts were mesomorphic, and they were least likely to be ectomorphic (Sheldon et al 1949). Although Sheldon's work was criticised on methodological and subjective grounds (because he rated his subjects' body types himself) his theories were supported in the area of criminal behaviour by Glueck and Glueck (1956) who found that in a sample of delinquents 60% were mesomorphs, whilst in a non-delinquent sample only 31% were, and by Cortés and Gatti (1972) who found in a sample of 100 delinquents that 57% were mesomorphic compared with 19% of controls. Wadsworth (1979), in contrast to Sheldon's finding that large and muscular convicts predominate, found that British delinquents who committed serious crimes tended to be smaller than average and were late in reaching puberty! West and Farrington (1973) in their longitudinal study of London working-class boys, found no association between delinquency and body shape or size. Feldman (1977) points out that these relationships between shape and criminality can be explained by expectations. Such features might catch the attention of police or influence juries or sentencing. The mesomorph is more likely to use aggression because size is on their side. In 1939 Thornton showed 20 photographs of criminals to people who were asked to choose one of four crimes each of the criminals might have committed. He found that people could match faces to crimes more reliably than would have been predicted by chance. Bull (1982) achieved similar results, this time using photographs of non-criminal individuals but still producing an association between some faces and some crimes, which was stronger than could have been predicted by chance. Masters and Greaves (1969) surveyed the incidence of facial deformities in 11,000 prisoners and concluded that 60% of them had facial deformities by comparison with 20% in a non-criminal population. Genetic Jacobs et al (1965) suggested that men with the XYY syndrome were more aggressive than normal 'XY' men. XYY men are over-represented in the prison population. There are 15 sufferers per 1,000 in prisons and 1 per 1000 in the general population. XYY men have lower intelligence and it could be this that leads to aggression. A Danish study, which screened 4591 men for the presence of XYY, found only 12 cases (Witkin et al., 1976). Whilst these individuals were indeed more likely to be involved in crime than chance would have predicted (41.7% of them, by comparison with 9.3% of the XY individuals), it was not involvement in violent crime. Their conclusion was that the over-representation of XYY males in prisons and special hospitals was more likely to be the result of other characteristics - low intelligence and above-average height - and the social reaction that these characteristics may have produced. Neurophysiological Raine 1994 used PET scans to study the living brains of impulsive killers. Damage was found in the pre-frontal cortex, which controls impulsive behaviour. The task used involved sustained attention. It involved watching a screen for 32 minutes and responding every time a 0 appeared. Impulsive individuals also missed many of the 0s. Oddly enough, prefrontal under arousal has also been found in politicians! ADHD Another suggestion is that certain individuals, as a result of genetic predisposition or brain damage at birth, suffer from a cluster of symptoms which render them incapable of moral control and because of cortical underarousal, they are constantly seeking stimulation. The symptoms appear in early childhood and are subsumed in the term attention deficit hyperactivity disorder (ADHD). They include inappropriate degrees of inattention, impulsiveness, challenging behaviour and hyperactivity. The symptom cluster is also known as MBD or minimal brain dysfunction. Moir and Jessel (1995) have suggested that this brain dysfunction can account for impulsive and seemingly irrational crimes, some of which involve violence. Moreover, they suggest that brain scans could identify the disorder in young children who are already showing behavioural problems and that treatment (Ritalin (a stimulant), biofeedback and parental training) could possibly prevent these children growing up to be seriously antisocial. Neurochemical The brain’s chemistry can be influenced by diet, for example, food additives, pollution or hypoglycaemia (low blood sugar levels associated with forms of diabetes). Dawn Stanton attacked her husband with a knife when hypoglycaemic. But not all diabetics without insulin act criminally. David Garabedian worked with strong pesticides and attacked and killed a woman where he was working. He was a quiet man who changed after the influence of the chemicals. The reason for the change was an increase in acytecholine in the hypothalamus. Brain chemistry in itself is not a sufficient explanation to account for all types of criminal behaviour. Individuals who take large amounts of steroids can become extremely violent (known as "roid rage"). Steroids, usually taken to increase muscle growth, also increase testosterone levels. Horace Williams, a body builder, beat a man to death after taking two thousand times the recommended dosage of steroids. Family studies: Can be used for Nature vs. nurture evaluation so provides both biological and environmental support. The Cambridge Study: problem families produce problem children Farrington, D.P. (1996) The Development of Offending and Antisocial Behaviour from Childhood to Adulthood. In Cordella, P & Siegel, L. (eds) Readings in Contemporary Criminological Theory. Boston: Northeast University Press. Aim: To describe the development of delinquent and criminal behaviour in inner city males, to investigate how far it could be predicted in advance, and to explain why juvenile delinquency began. The original study was begun in 1961—62: this is a follow-up study of 411 London boys, born mostly in 1953. Method: Design: This is a longitudinal study based on interviews and tests conducted at various ages over, to date, 24 years. Participants: The great majority of the sample was chosen by taking all the boys who were then 8—9 years old and on the registers of six state primary schools in one location in London. The boys were almost all white and predominantly from working-class families. Measures used: 1 Tests and interviews at school at ages 8, 10 and 14 years. Interviews in the research office at about 16, 18 and 21 and in homes at about 25 and 31. The tests in schools measured intelligence, attainment, personality and psychomotor skills. The interviews collected infor-mation concerning employment history, relationships with females, leisure activities such as drinking and fighting, and offending behaviour. 2 interviews with the parents about once a year from when the study began (when the boys were about 8) to when they were 14 or 15 years old, It was mainly the mothers who were interviewed. The parents provided information on family size, employment history, childrearing practices, degree of supervision and whether there had been any temporary separations. 3 Questionnaires completed by the boys’ teachers when the boys were 8, 10, 12 and 14. These concerned troublesome and aggressive behaviour, attainment, and truancy. Peers provided information on popularity, daring, dishonesty and troublesomeness. 4 Records From the Criminal Record Office to gain information on convictions of the boys, their parents, their siblings and, later, their wives or cohabitees. Minor offences such as common assault, traffic offences and drunkenness were not included in these statistics. Results: Statistics on crimes committed: 1 By the age of 32, 37 per cent of the males had committed criminal offences. The peak age was 17. Nearly three quarters of those convicted as juveniles were reconvicted between the ages of 17 and 24, and nearly half of the juvenile offenders were reconvicted between the ages of 25 and 32. 2 Offending was very much concentrated in families. Just 4 per cent of the 400 families accounted for 50 per cent of all convictions of all family members. 3 The worst offenders tended to be from large-sized, multi-problem families. 4 Most juvenile and young adult offences occurred with other people, but this co-offending declined with age. Co-offending with brothers was not uncommon when the siblings were close in age but co-offending with fathers (or mothers) was very rare. 5 The most common crimes in late teens were burglary, shoplifting, theft of and from vehicles, and vandalism. All of these declined in the twenties, but theft from work increased, 6 Self reports showed that 96 per cent of the males had committed at least one crime that might have led to conviction, so criminal behaviour was not deviant. Predictors of crime at age 8—10: 1 Antisocial child behaviour including troublesomeness, dishonesty and aggression. 2 Hyperactivity-impulsivity-attention deficit. 3 Low intelligence and poor school attainment. 4 Family criminality. 5 Family poverty, including low family income, large family size and poor housing. 6 Poor parental child-rearing techniques, poor supervision, parental conflict and separation from parents. Conclusion: Any one of these factors independently predicts offending and the following suggestions are made as to the reasons for this. Children from poorer families are more likely to offend because, due to poor school attainment and an inability to manipulate abstract concepts, they are less able to achieve their goals legally. Impulsive children cannot see the consequences of their actions and desire immediate gratification. Children who are exposed to poor child-rearing practices, conflict or separation do not build up inhibitions against antisocial behaviour. Lastly, children from criminal families and those with delinquent friends develop anti-establishment attitudes and the belief that it is justifiable to offend. This research demonstrates that problem children grow into problem adults who in turn produce problem children. Sooner or later serious measures must be taken to break this cycle. Twin studies and adoption studies An 'MZ apart' study is when two monozygotic children have been brought up apart. If both turn out to be criminals then this would be support for the genetic explanation. The degree of similarity between two twins is known as the concordance rate. This rate can then be compared with dizygotic twins who are brought up together ('DZ together'). Looking at a number of studies the average concordance rate is 55% for MZ twins and 17% for DZ twins (Bartol, 1999). Evaluation 1 Different studies define criminality in different ways (e.g. traffic violations, military offences, treason during World war 2). 2 Quasi-experimental designs are not so controlled as experimental designs. 3 Age of separation of MZ twins. 4. Misclassification of twins as MZ or DZ. 5. MZ twins look alike and may therefore generate more similar social responses than DZ twins. This means that in addition to sharing the same genes, they may also share an almost identical social environment. 6. · MZ twins often have a very close: relationship and may therefore develop similar interests, which might include criminal behaviour. 7. · Very small sample size in some studies, because of the inherent difficulties in obtaining access to criminal twins. 8. · Variable definitions of criminal behaviour. Recent studies looking at measures of personality and intelligence in relation to MZ twins reared apart have found some striking similarities (Bouchard et al., 1990). A retrospective study by Mednick et al (1987) looked at court convictions in a small European country and found 14,000 adoptees amongst them. The criminal records of their biological and adoptive parents were then investigated. Many of the adoptees had criminal biological parents (particularly strong relationship for sons and fathers). There was no relationship in the types of crime committed. Where there was an improvement in social conditions there was a reduction in crime (going against the genetic explanation). Biological parents have Adoptive parents have % of sons with criminal criminal record criminal record record (Mednick 1987) No No 13.5 Yes No 20.0 No Yes 14.7 Yes Yes 24.5 Evaluation 1 2 3 4 Age of adoption Amount of contact with biological parents (contamination effect) Adoptive family selected to be similar to biological family. Small sample sizes. Psychological: Eysenck's Personality theory and crime Extraverts need excitement so they are more likely to seek crime in order to gain excitement. Eysenck proposed that extraverts do not condition easily. Whereas others would learn that crime does not pay through classical and operant conditioning, the extravert would not learn these associations. A third dimension was added; psychoticism. Those high in psychoticism are 'egocentric, aggressive, impulsive, impersonal, cold, lacking in empathy and concern for others, and generally unconcerned about the rights and welfare of other people' (Eysenck 1982). Eysenck predicted that criminals would score highly on extraversion, psychoticism and unstableness (Eysenck 1977). Much research has been generated in attempts to verify Eysenck’s prediction that criminals should achieve high scores in E (extraversion), N (neuroticism) and P (psychoticisin). Whilst there has been some support for an association between P scores and criminal behaviour, there has been little support for the configuration of E, N and P scores. Moreover, there has been serious criticism of the authority with which this particular theory has been presented when there are misgivings on any evidence for its theoretical foundation (Trasler. 1987). Also, there is little evidence to support unstableness or emotionality and crime. However, Eysenck has provided a testable theory that has stimulated international research. THE FREUDIAN APPROACH The central concept of psychoanalysis, and the one that Freud first put forth, is the unconscious. The concept had been around before Freud, but he was the one that made the most out of it, arguing that traumatic experiences in early childhood left their mark on the individual despite the fact that the individual was not aware of these experiences. The idea of unconscious determination of behavior flew headfirst against the idea of free will, and was quickly jumped on by positivistic criminology. The next most important idea is conflict, and Freud postulated the existence of a three-part personality (an idea going back to Plato) consisting of id, ego, and superego which operated in constant conflict with one another (primarily between the id and superego) producing % of sons with criminal record (Bohman, 1995) 3 12 7 40 the basic problem of guilt which required the use of one or more defense mechanisms. The idea of personality conflict as a cause of crime became quite popular among both scientists and the general public. The id is a part of the unconscious that contains all the urges and impulses, including what is called the libido, a kind of generalized sexual energy that is used for everything from survival instincts to appreciation of art. The id is also kind of stubborn, for it responds only to what Freud called the pleasure principle (if it feels good, do it), and nothing else. The ego is the only part of the conscious personality. It's what the person is aware of when they think about themselves, and is what they usually try to project toward others. The ego is dominated by what Freud called the reality principle (an orientation to the real world in which the person lives). It is continually trying to mediate the demands of the id and prohibitions of the superego. The superego is a part of the unconscious that is the voice of conscience (doing what is right) and the source of self-criticism. It reflects society's moral values to some degree, and a person is sometimes aware of their own morality and ethics, but the superego contains a vast number of codes, or prohibitions, that are issued mostly unconsciously in the form of commands or "don't" statements. The superego is also somewhat tricky, in that it will try to portray what it wants the person to do in grandiose, glowing terms, what Freud called the ego-ideal, which arises out of the person's first great love attachment (usually a parent). The assumption is that children raised by parents experience love conditionally (when they do something right), and the child internalizes these experiences as a series of real or imagined judgmental statements. Guilt is a very common problem because of all the urges and drives coming from the id and all the prohibitions and codes in the superego. There are a variety of ways an individual handles guilt, and these are called defense mechanisms (see table for complete list). Desires of the id are diverted to healthy outlets Sublimation approved by the superego Desires of the id are stuffed back into Repression subconscious and the person denies they exist or engages in Freudian slips Desires of the id are followed impulsively to Regression escape from hearing the superego (reality) Anxiety about following desires of the id goes Denial/Intellectualization unacknowledged or treated unemotionally Prohibitions of the superego are applied as Projection standard for judging others and not oneself Prohibitions of the superego are so strong that Fixation the person develops fears/phobias Superego is so strong that the person continually Undoing makes amends or apologies for what they do Both id and superego are so strong that person Reaction formation does the opposite of both, sometimes identifying with aggressors Both id and superego are so strong and ego is so weak that person settles for second best or any Displacement available substitute (something better than nothing) Of the defense mechanisms, psychoanalysts have put forward displacement as their number one choice for explaining crime. A few criminologists have explored the others, most notably, reaction formation, but the list remains largely unexhausted because, essentially, the ideas are untestable. Freud also provided a theory of human development. These ideas revolved around his terms for the three stages of early childhood. The oral stage (age 0-2) is when a person develops their sense of satisfaction or satiation, of figuring out how much is enough (e.g. of food and drink) which has implications for much of an eater, drinker, or smoker a person is in adulthood. The anal stage (age 2-3) is when a person develops their sense of orderliness, of figuring out their preferred levels of cleanliness (e.g. as in toilet training). The genital stage (age 3-4) is when a person develops their sexuality, of figuring out their sexual preferences and whether they are capable of real love or not. Male children go thru what is called an Oedipus Complex (with a comparable Electra Complex in females). Both complexes involve sexual feelings for the parent of the opposite sex (and are called "inverted" complexes in cases of homosexuality), and how these feelings are resolved determines how capable the person is of real love later in life. The primary technique of psychoanalysis is transference, the process of the patient, through free association and "talk therapy", reenacting or reliving their early childhood experiences with the therapist. The therapist, in short, becomes a love object, for the patient, but without the therapist going too far or becoming too involved, which is called counter-transference. Without therapy, a person will engage in amateur transference with other people, a process whereby they play out a "script" or replay the same failed relationships over and over again. Freud never really had much to say about crime, other than it was most likely motivated by guilt, committed by people with overdeveloped superegos, and characterized by unconscious errors (Freudian slips) which appeared to represent a desire to get caught and be punished. The inconsistencies in this (is it Repression, Fixation, or what) is why it’s often said that there is no purely Freudian theory of crime (other than the idea the criminals want to get caught). It was up to the followers of Freud who revised his theories (the Neo-Freudians) to shed light on the psychoanalytic explanation of crime. One of the first neo-Freudians to do so was August Aichorn, author of Wayward Youth, who took the position that it was not overdeveloped superegos but an underdeveloped superego that primarily caused crime. He believed that some criminals, raised as children without loving parents or parents at all, developed unregulated ids. Others were overindulged at the oral stage and required different treatments. In any event, Aichorn's ideas popularized the notion that delinquents needed unconditional love rather than a punitive, institutionalized setting. The ideas of maternal deprivation or love deprivation as a cause of crime are still popular. Redl & Wineman were another group of neo-Freudians who studied Children Who Hate, and took on the Freudian notion of Oedipus Complex. According to orthodox Freudian theory, criminals should hate their fathers more than their mothers, but Redl & Wineman found that criminals hate both their parents, both father and mother. In fact, they hadn't gone through a genital stage at all. Their egos were therefore undeveloped, and with nothing to mediate between the id and superego, their personalities were nothing but an endless series of raging conflicts, and this is what they called the "delinquent ego". Healy provided what is perhaps the greatest contribution to Neo-Freudian theory. He clarified that Displacement was the most common defence mechanism used by delinquents. He discovered this by using the "life history" method at his psychiatric clinic in Chicago where he pioneered the process of a nurse taking vitals, a physician examination, a social worker taking a social history, a clinical psychologist testing, and a psychiatrist treating. He estimated that 91% of delinquents were emotionally disturbed, 50% because of a broken home, and the rest because of too much or too little parental discipline. Alexander and Healy (1935) suggested that children need to progress from the pleasure principal (being id dominated and therefore needing instant gratification) to the reality principle (where the ego is dominant). Criminals are those children who do not make this transition. According to Freud the child needs a stable home environment in order to successfully make this transition. Research has supported the fact that most criminals come from unstable homes. The reality principle was central in the explanation of crime offered by F. Alexander and Staub (1931) and F. Alexander and Healy (1935). The criminal from this perspective is someone who is unable to postpone immediate gratification in order to achieve greater long-term gains. In other words, the criminal is one who has failed to progress from the pleasure principle to the reality principle. The antisocial, criminal behaviour in adulthood is seen as a display of characteristics formed during childhood. Healy and Bronner (1936) applied another psychoanalytic concept, sublimation, to the explanation of crime. Sublimation is the process by which instinctual impulses are channelled into other thoughts, emotions, and behaviours. Thus the criminal act, it is argued, results from inner unsatisfied desires and dissatisfactions; these unsatisfied wishes, in turn, stem from a failure to experience strong emotional ties with another person, usually a parent. Thus the delinquency is an 'acting out' or sublimation of inner processes. Healy and Bronner provided evidence to support their theory with two groups of children from a child guidance clinic. Compared to a non-delinquent group, the children who had committed offences had less stable families and also showed greater signs of emotional disturbance. Other psychoanalytic explanations for crime have focused on the inability to control impulsive, pleasure-seeking drives (Abramson 1944); unconscious parental permissiveness which gives approval to delinquent behaviour, hence leading to a poorly developed superego and thereby a lack of control over antisocial impulses (Johnson and Szurek 1952); and acting out of feelings of oppression and helplessness (Halleck 1971). Redl and Toch (1979) and R.J. Marshall (1983) provide reviews of the psychoanalytic perspective on crime. John Bowlby (1946) (see Hodges and Tizard) studied 44 juvenile delinquents and compared them with non-criminal disturbed juveniles. 39% of the delinquents had experienced complete separation from their mothers for six-months or more during the first five years of their lives compared with 5% of the control group. Problems with Bowlby's research: unrepresentative samples, poor matching for control group, low reliability in the interviews with participants (Feldmann 1977). Also whether or not the effects are reversible are contested (see Hodges and Tizard). Koluchova (1976) studied a pair of Czech twins and reported that although they were severely neglected for the first 7 years of their lives they were deemed normal by the time they were 14 after being cared for. Clarke and Clarke (1976) studied children from deprived backgrounds using a longitudinal study and found there were many factors that contributed to the child becoming a criminal, not just whether or not they were maternally deprived. Psychoanalytic explanations are difficult to test. However, the effects of emotional or sexual abuse can well be believed when we find that 'serial killers' such as Frederick and Rosemary West suffered terribly as children (Wansell 1996). Out of 36 sex murderers interviewed in the USA 42% were found to have been sexually abused as youngsters (Ressler et al 1988). Dietz and Warren (1995) found that 76% of the 41 serial rapists that they interviewed were abused when young. Having said this though only about 10% of abused children go on to commit crimes. Psychoanalytic theory would predict that 'over-controlled' individuals could save up all their emotional turmoil and then explode into a torrent of violence! However, one of the essential assumptions of psychoanalytic theory is that females will have a less developed superego/conscience and will therefore commit more crime and this is simply not borne out by criminal statistics. Bandura's Social learning theory, instead of looking at how the past affects behaviour says instead that violent behaviour is modelled from others. This occurs mainly through media such as films and television. Social learning theory is an extension of operant principles. While operant theory maintains that behaviour is acquired through reinforcement and punishment from the environment, social learning theory holds that behaviour can also be learned at the cognitive level through observing the actions of other people. Once learned the behaviour may be reinforced or punished by its consequences like any operant behaviour. Bandura (1977) suggests that there are three aspects to motivation: 1. External reinforcement (as in operant theory) 2. Vicarious reinforcement – the observation of other people being rewarded or punished for their behaviour 3. Self-reinforcement – gaining internal satisfaction from an activity, which therefore motivates the individual to behave in a similar way in the future. Models who are regarded as successful or of a high status are more effective in motivating an individual to copy their behaviour. Observational learning is thought to take place primarily in three contexts: 1. In the family 2. in the prevalent sub culture 3. Through cultural symbols such as television and books (Bandura 1976). Learning theory and social learning theories of crime evaluation For · The theories are based on carefully conducted empirical research · They can help to explain why criminality does, to an extent run in families. · Males and females are socialised very differently, with females encouraged not be aggressive and to conform, males are encouraged to “stick up for themselves” and be independent. Against · The studies on which these theories are based are conducted in laboratories or other artificial environments in carefully controlled conditions. They therefore lack validity in that they may not be sampling behaviour as it occurs in real life situations. · The fact that criminal behaviour tends to run in families is not necessarily due to imitation but may be due to circumstances such as social deprivation, or to genetic propensity to behave in an anti-social way. · There are biological differences between men and women, especially hormonal ones, and this, rather than socialisation, may account for differential rates of crime between men and women. Sutherland (1939) The view that criminal behaviour, in common with all other behaviour, is learned was most clearly expressed by Sutherland (1939) in his theory of ‘differential association’, which states that: · criminal behaviour is learned; · the learning is through association with other people; · the main part of the learning takes place within close personal groups; · the learning includes techniques to carry out certain crimes and also specific attitudes and motives conducive towards committing crime; · the learning experiences — differential associations — will vary in frequency and importance for each individual; · the process of learning criminal behaviour is no different from the learning of any other behaviour. Sutherland also attempted an analysis of the gender differential in crime, arguing that boys are more likely to become delinquent than girls because they are less strictly controlled and are taught to be aggressive and active risk seekers, all characteristics likely to bring success in the criminal world and, indeed, in the world generally.
