Psychologists through th yars hav possssd knowldg on criminal bhaviour through xcuting psychological rsarch. Numrous psychologists hav mbarkd on studis but th focus is on four particular studis chosn for dpr analysis. Firstly, Shldon had a thory of criminal bhavior that highlightd th significanc of physical apparanc. H trid to find a corrlation btwn a prsons body build (somatotyp) and criminal bhavior. (Taylor et al., 54)
There are three basic body types, Endomorph who has a pear shaped body with wide hips, a rounded head and a lot of fat on the upper arms and thighs. A Mesomorph who has a wedge shaped body, wide shoulders and narrow hips, a massive cubical head and heavily muscled shoulders, arms and legs. Then lastly an Ectomorph who has narrow shoulders and hips, a narrow chest and abdomen, thin arms and legs and a high forehead and receding chin. Conversely, one of the biggest criticisms of his study was that not any one person is completely 100 percent one of these body types. Some people are meso endo morph where they would be tall and muscular. He believed that somatotype was linked with a persons temperament so an endomorph would be relaxed, endomorphs tend to be restrained and a Mesomorph energetic and adventures. Considering this he then came to the conclusion that with the Mesomorph being adventurous this would lead them to participate in criminal activities. His study raises the problematic issue of self-fulfilling prophecy. (Gottfredson, S. D., & Taylor, R. B., 48) This is where people label people as to what they believe they should be like. For instance as he believes Mesomorph’s are going to be more aggressive, being included in criminal activity then he may be influenced towards portraying them as more criminally natured than they truthfully appear to be. To test his theory he obtained evidence using studies in which the somatotypes of college students and delinquents were assed from photographs. Each photograph was rated for Mesomorphy on a scale of 1 to 7 with 1 lowest and 7 highest. His findings showed that the delinquents had on average a higher Mesomorphy rating than the college students with a mean score rating of 4.6 compared to 3.8. These findings therefore support the theory that Mesomorphy is associated with criminal tendencies. He also found that some criminals did not fit the mesomorph somatotype. This would suggest that it is indecisive from this study there is any correlation between the two, meaning that another perspective may have to provide answers in explaining criminal behaviour.
Bandura suggests violent behavior is learned and not inherited, supporting the theory of nurture over nature. (Taylor et al., 71) The aim of the study was to see if children would imitate aggressive behavior when given the opportunity after observing role models showing aggressive behavior. The children were exposed to aggressive behavior in the form of the role model beating up a bobo dole. The role model would then leave the room and psychologists observed the children to see what their reaction would be. He was trying to discover if violent behavior could be “copied" and so learned and not inherited which many other psychologists believed. The results of this study have permitted psychologists to learn much about why violent behavior is carried out. He found that children that had been exposed to violent behavior showed more aggression than children that hadn’t been exposed.
Children who saw the aggressive role model usually showed more imitation of the role model in verbal and physical aggression than those children who hadn’t seen the aggressive role model. These children showed low levels of aggression and were relaxed which shows in this case it appears violent behavior has been leant and copied by being exposed to it. Yet as ever there are problems. There is a case to argue that this isn’t a true representative of how children would react to real people as his only used dolls meaning the study lacks ecological validity. If Bandura however was to conduct his experiment on real people, ethics would hinder the study, so this goes far to show the difficulty experienced in trying to conduct ethical studies.
Lombroso suggests that criminals were genetically born into criminals and could be distinguished by strong characteristics such as heavy brows, strong jaw lines and lower than average intelligence. he said that murderers had blood shot eyes, strong jaws and curly hair where as sex offenders were claimed to have thick lips and projecting ears. He tested his theory by studying criminals and there distinguishing features with. However he did not test any non-criminals in order to identify weather it is just criminals that had these features or if they were universal to all people weather they are offenders or not. Also he study was very unethical as it was labeling people in society as being something they may not have been. For example some one with projecting ears and thick lips would be labeled as a sex offender and so would be treated differently in society. This was just one of many problems with the study so all in all there is very little we can learn from this study as it had so many problems regarding it. However his study is not to be set aside, as it could have been the trigger in moving the study of criminal behaviour away from subjective, moral and philosophical comment and into scientific research opening up more avenues than he closes.
Eysenck like Lonmbroso suggests that criminal behavior arises from particular personality traits, which thus means that he believes criminal behavior is inherent and not nurtured as people are born with particular personality traits. Originally he put forward that most of the differences between people could be reduced down to just two particular dimensions of personality, these being neuroticism and extraversion. A person with high neuroticism tends to have mood swings and depression where as a person with low neuroticism tends to be laid back and emotionally stable. A person with high extraversion tends to need a lot of stimulation from the out side environment and a person with a low extraversion tends not to need very much stimulation at all. It is important not to think as these two types as different people but just ways in which people can vary. To test these traits he devised a number of simple psychometric tests. He proposed that people with a high neuroticism would find it more difficult to learn socially appropriate behavior and so may become criminals. After he had carried out his tests he then introduced another personality trait, psychoticism. A person that was high in this would be cold, uncaring and aggressive and so there fore would be very likely to become a criminal. As with neuroticism and extraversion he believed this trait was very much genetic and not learned which again supports the nature over nurture argument. After carrying out his tests he concluded that there was a significant correlation between criminals and their extraversion, neuroticism and psychoticism. However many psychologists have argued against this and said the relation ship between offending and extraversion is inconsistent. His study has come up against many criticisms. One such criticism was it was a very crude way of testing peoples personality trends and many psychologists had doubts as to if it was valid and raised questions as to if he was testing what he though he was testing. On reflection, his theory of criminal behavior hasn’t been useful in describing how certain personalities might become involved in crime and is unfulfilling as a theory of criminal behavior. (Taylor et al., 39)
Every study had its positives and its negatives as a piece of psychological research. Sheldon’s study was very unethical due to labeling people to be murderers and sex offenders by the way they look. This would cause distress and harm to people and so ethical guidelines aren’t being followed. Lombroso also labeled people by distinguishing features such as jaw lines and ears, which would have caused the same harm to subjects. These studies are also reductionist as they have to isolate areas of psychology to measure the independent variables, meaning they fail to consider other factors involved, say in a cognitive perspective for instance. (Gottfredson, S. D., & Taylor, R. B., 74)
As Bandura’s and Lomboro’s studies were correlational research, it forced restriction where they could not establish a cause and affect, which lead to their being confounding variables. In these four studies each psychologist has his/her views on the nature vs. nurture debate. Eysenck supported the nature argument, as he believed that people’s personalites made them criminals born with certain personality traits. Sheldon also believed it was nature because people are born with certain body types and so he believed this affect the way they act in criminal situations. Lombroso also supported this in the same way, as the shape of your skull is very much a thing you are born with and he believed this was what affected someone’s behavior. Bandura supported the nurture argument and upon consideration I perceive this overall as the strongest piece of evidence suggesting that violent behavior is learned and not inherited The over-riding problem psychologist’s face when arguing criminal behavior is inherent rather than nurtured is proving what someone is born with and what they have develop through life. It is difficult to distinguish how particular bodies develop and how they could be changed through situations. It is argued that people’s somatotypes change if they become a criminal and the majority of criminals are mesomorph whilst prior to their criminal activity it wasn’t related to body shape. It can all point down to validity and if psychologists are really testing what they think they are testing. I personally perceive the way forward for society as being through the promotion of more positive role models for people to adhere to. Bandura has shown us how role models can affect behaviour so why should it not apply in a more positive direction, which is anti violent. The labeling of criminals also does little to help their re-entrance into society, and through the publicity and proactive application of rehabilitation criminals can be seen to make more of a life outside and would be less likely to repeat offences.
Social Deviance Theory is an important explanation in the theory of crime. Without this explanation, it would be impossible to explain a great deal of the factors involved in juvenile delinquency. Social Deviance Theory and Development Theories are the umbrellas under which other theories used to explain juvenile delinquency fall. Depending on the criminal and the type of crime committed, different theories are used. Social Deviance is acting against the norms of society. Development Theory deals with the manner in which a child develops into adulthood. This includes any insults or trauma, the individual's behavioral response, problems in school, problems in society, etc. When a child experiences trauma that child may act out. this acting out for attention can easily become delinquent behavior. Developmental Theory is not the only theory that explains crime. Social Deviance Theory is another theory that can explain crime, of which juvenile delinquency is a type. According to Hoffman, et al, (1997), R. K. Merton had certain psychological theories about crime and criminal behavior. In fact, "Merton recognized that a conceptional framework was needed to better explain social deviance and criminality" (180). Anomie is one kind of social deviance. Anomie represents social instability. The person's standards and values are broken or non-existent (Hoffman, et al, 1997). It is not surprising that many young people today have broken or non-existent standards. Both parents work, or there is only one parent. Some crime can be explained by developmental theory. Female delinquency is one that can. According to empirical research, interpersonal problems cause subjective strain or a response of distress. The literature concerning development points to the adolescent period as the time in which this behavior is particularly strong. Adolescents lack the skills that adults have available, such as coping skills, social supports, and coping resources. Males are not as concerned with interpersonal goals as females are. This points to the evidence that relational or interpersonal problems are more likely to lead to female deviance. This type of deviance manifests in delinquency (Agnew & Brezina, 1997). Many young people see themselves as mature, however, they are simply not mature enough for their coping mechanisms to have properly developed. This leads to problems. According to Thoits (1995), sociologists spend a great deal of time attempting to explain the deviant behavior of juvenile delinquency. Their etiological theories have generated extensive research in the areas of anomie theory, conflict theory, control theory, differential association/learning theory, and labeling theory, which are forms of Social Deviance Theory.
