Criminal behaviour is a complex phenomenon and so has no individual explanation. Psychology; the scientific study of the human mind and behaviour, has therefore attempted to explain crime and deviance through its several approaches. The two major contributing approaches to the explanation of criminal behaviour that will be discussed in this essay are the bio-psychological and behavioural approaches. Biopsychology is focused primarily on the idea of genetics and the neuropsychological/neurophysiological as the determining factors in behaviour. It very much takes the side of nature in the nature vs nurture debate. According to this approach the majority of the individual’s personality, cognitive as well as physical capabilities and most other …show more content…
This takes preference in the nurture side of the nature vs nurture debate. According to the behavioural approach all behaviour is determined by external factors and the way in which the environment (including other people) constantly influence behaviour. Most contemporary psychologists adhere to a compromise between these two approaches in explaining criminal behaviour (and indeed all behaviour). It has been established that biological and behavioural factors contribute to all behaviour, it is merely a matter of discovering the ratio of contribution between these biological and behavioural factors. Nevertheless some psychologists stand wholly to their own particular perspective using the evidence acquired from their own particular research. Research into the explanation for criminal behaviour has been ongoing since the 19th century. Credit is given to Cesare Lombroso as the first to study criminal behaviour in depth. In 1876 he argued that the criminal was “a separate species” and developed a curious theory based on the physical characteristics of criminals. His theory that physical characteristics are the determining factor for the predisposition of criminal behaviour is an example of the bio-psychological approach to criminal …show more content…
Identical/monozygotic twins share the same DNA and non-identical/dizygotic twins share half. Therefore the concordance rate of criminal behaviour between these two types of twins should offer insight into the role of genetics in criminal behaviour. Johannes Lange was the first to conduct twin studies in relation to criminality. In a 1929 study of 13 pairs of identical twins and 17 pairs of non-identical twins he found a concordance rate of 77% for the former and 12% for the latter. His results were criticised due to the small size of the sample. However, though not as high, subsequent studies have still revealed a considerably higher criminal concordance rate among identical twins. This shows at least to some extent that genetics does play a role in criminal

Crime causation began to be a focus of study in the rapidly developing biological and behavioral sciences during the 19th century. Early biological theories proposed that criminal behavior is rooted in biology and based on inherited traits. Cesare Lombroso (1836-1909), an Italian army prison physician, coined the term “atavism” to describe “the nature of the criminal”...
People are uniquely different and because of this reason, they do have different behaviors. Crime is one kind of behavior that an individual can engage in. They are punishable by the law and may be prosecuted by the state (Helfgott, 2008). There are different theories existing that try to explain the actions of criminals. They deeply explain what causes an individual to commit a criminal activity. This paper discusses some examples of the biological theories, social theories and psychological theories of crime.
Trait theory views criminality as a product of abnormal biological or psychological traits. It is based on a mix between biological factors and environmental factors. Certain traits alone cannot determine criminality. We are born with certain traits and these traits along with certain environmental factors can cause criminality (Siegel, 2013). According to (Siegel, 2013), the study of sociobiology sparked interest in biological or genetic makeup as an explanation for crime and delinquency. The thought is that biological or genetic makeup controls human behavior, and if this is true, then it should also be responsible for determining whether a person chooses crime or conventional behavior. This theory is referred to as trait theory (Siegel, 2013). According to Siegel (2013), due to the fact that offenders are different, one cannot pinpoint causality to crime to just a single biological or psychological attribute. Trait theorist looks at personal traits like intelligence, personality, and chemical and genetic makeup; and environmental factors, such as family life, educational attainment, economic factors, and neighborhood conditions (Siegel, 2013). There are the Biosocial Trait theories an...
Cesare Lombroso, medical criminologist, headed the school. Enrico Ferri and Raffaele Garafolo were Lombroso’s disciples, both of whom also headed, as well as had their own opinions on the biological crime theory. Lombroso argued that “criminality was a biological trait found in some human beings” (Boundless, 2015, 1). Today, the biological theory emphasizes the relationship between genetics and crime. The biological theory of crime has evolved over the years in the sense that, initially, the theory was primarily based on physical features. In contrast, it is now primarily based on genetics. As technology has also evolved as well as our knowledge on genetics, this only makes sense (Boundless,
Nature versus nurture has been argued in attempt to understand how criminals behave. The theory of what influences psychopath and serial killers’ violent and destructive pathways has not been agreed on till this day. Criminals such as psychopaths and serial killers have been researched for the past two decades. Scientists have found that genetics is a determining factor of who becomes a serial killer. It is important to understand the determinants involved within a serial killer, because if these social and environmental causes are discovered, they can be altered and controlled to reduce crime (Lykken, 1993). With more studies, we would therefore prevent mass murders and could assist in significant reductions of crime within society.
In today’s society, one will find that there are many different factors that go into the development of a criminal mind, and it is impossible to single out one particular cause of criminal behavior. Criminal behavior often stems from both biological and environmental factors. In many cases criminals share similar physical traits which the general population do not usually have. For example criminals have smaller brains than properly adjusted individuals. However biological reasons cannot solely be the cause of criminal behavior. Therefore, one must look to other sources as to how a criminal mind is developed. Social and environmental factors also are at fault for developing a person to the point at which they are lead to committing a criminal act. Often, someone who has committed a violent crime shows evidence of a poorly developed childhood, or the unsuitable current conditions in which the subject lives. In addition if one studies victimology which is the role that the victim plays in the crime, it is apparent that there are many different causes for criminal behavior. Through the examination of biological factors, in addition to the social and environmental factors which make up a criminal mind, one can conclude that a criminal often is born with traits common to those of criminals, it is the environment that exist around them that brings out the criminal within them to commit indecent acts of crime.
In this article the two authors research the connection between genetic factors and criminal behavior. They look at the causes that make someone act in a criminal way. There are several factors looked at in connection to the cause such as social factors and environmental variables. The social factors being the more examined of the two. They hypothesized that other factors in performance or alone with environmental variables would lead to better understanding of why some people become criminal. The genetic factor of influence due to mental disorders was posed to have a slight role in affecting people to show criminal behavior. Another cause looked at was the combination of genetic and environmental factors, with a possible result of having a higher risk for criminal behavior.
Ceasare Lombroso is one of the first scholars that developed ideas to explain the reasons why some people behaved more deviant than others or committed crimes. Lombroso conducted research on several prisoners measuring facial features and skull size. He later published a book called “the criminal man in 1876” (Dwyer, 2001 p.15). Lombroso believed that there was two different types of human beings, those who had evolved properly and another which did not. They were more primitive an...
Theories that are based on biological Factors and criminal behavior have always been slightly ludicrous to me. Biological theories place an excessive emphasis on the idea that individuals are “born badly” with little regard to the many other factors that play a part in this behavior. Criminal behavior may be learned throughout one’s life, but there is not sufficient evidence that proves crime is an inherited trait. In the Born to Be Bad article, Lanier describes the early belief of biological theories as distinctive predispositions that under particular conditions will cause an individual to commit criminal acts. (Lanier, p. 92) Biological criminologists are expected to study the “criminal” rather than the act itself. This goes as far as studying physical features, such as body type, eyes, and the shape or size of one’s head. “Since criminals were less developed, Lombroso felt they could be identified by physical stigmata, or visible physical abnormalities…characteristics as asymmetry of the face; supernumerary nipples, toes, or fingers; enormous jaws; handle-shaped or sensible ears; insensibility to pain; acute sight; and so on.” (Lanier. P. 94). It baffles me that physical features were ever considered a reliable explanation to criminal behavior. To compare one’s features to criminal behavior is not only stereotypical, but also highly unreliable.
Crime is defined as an action or omission that constitutes an offense that may be prosecuted by the state and is punishable by law. The idea of the born criminal was introduced by Italian army physician Cesare Lombroso, he began to study delinquents in the 1860’s (p. 69); he believed that criminology was based on the individual criminal themselves. Lombroso collected the skulls of criminals, and it was believed that the key to criminality manifested in the deformities of the skull; these bumps and lumps were presumed to be the links to physical and mental illness. Classical criminology and positivist criminology, have influenced the current development of criminological theory.
This study includes the social and emotional setting of the criminal from a young age to their adult life. This also involves the examination of their ecological influences such as their economic status, heredities, family structure, and learning disabilities. In addition, criminal psychologists establish the mental state in which the criminal was in at the time which the delinquency occurred. This is important because understanding their mental state can help psychologists understand the person’s motives for committing this crime or precise act. Criminal psychology is vital in determining whether the person was in control of their mental abilities during the act of the crime, which is important in cases where senselessness is a defense from responsibility for their unlawful
These theories represent part of the classic psychological debate, nature versus nurture. Are individuals predisposed to becoming a criminal or are they made through their environment. There are various theories within the biological explanation as to why individuals commit criminal behaviour, these include: genetic theory, hereditary theory, psychosis and brain injury theory. In the next few paragraphs examples of each will be shown. The first theory to be explored is the hereditary theory, which stems from Cesare Lombroso (1876) father of criminology, (Feldman, 1993) whose studies were carried out by morphology.
Different schools of thought propose varying theoretical models of criminality. It is agreeable that criminal behaviour is deep rooted in societies and screams for attention. Biological, Social ecological and psychological model theories are key to helping researchers gain deeper comprehension of criminal behaviour and ways to avert them before they become a menace to society. All these theories put forward a multitude of factors on the outlooks on crime. All these theories have valid relevancy to continuous research on criminal behaviour.
I now know that criminology prefer to highlight the correlations between crimes’ social climates and criminals’ psychological states of mind. While some argues that criminal behavior is a result of individuals’ association with criminal peers, other claims that crime is a reflection of an individual’s genetic disadvantages. I have come to learn that there are no universally agreed formulas on decoding crimes and criminal behaviors. What we have, however, is a manual full of academic opinions and subjective views that have emerged alongside of the development of criminology. At the same time, the volume of conflicting perspectives that I have stumble upon in studying criminology reminded me again that the success of our current assessment models has yet to be determined. Thus, the study of criminology is an appropriate practice that will further prepare me to conduct meaningful research on legal studies and to provide accurate and in-depth findings in the near
