Biological Explanations of Criminal Behavior

Biological Theories have been related to crime for a long time. The Biological Theory talks about how one’s brain has an impact on committing crime or not. Dr. Jim Fallon, a neuroscientist from California talks about the biological influences in a brain. He believes that the combination of three major aspects can determine whether someone is psychopathic or not. Fallon states a combination of genes, damage to the person 's brain and the environment surrounding the individual will have the biggest impact on a person (Fallon, 2009). A real world example of the biological theory in full effect was the crimes of David Berkowitz, aka “Son of Sam. Berkowitz was accused and found guilty of killing over 6 people in New York City. After being convicted and locked up for a few years, studies had shown that Berkowitz had been diagnosed with schizophrenia. Berkowitz also claimed that his neighbor’s dog, Sam had told him to do the killings as well (Biography). Comparing the Biological theory to my own life was pretty simple because there is a genetic factor that runs in my dad’s side and that is tempers. Tempers tend to flare fairly easy, and luckily so far there has no issues with the law, however like Fallon had said, with the right combination, anyone is possible to commit a crime at any time. I feel like in a biological theory, this would have a major impact on my life

Biological factors alone are not a sufficient reason why crime occurs. An example would be looking at testosterone and adult deviance. Most studies have shown no correlation with circulating testosterone and behavior. However, there is significance to examining biological factors. The answer lies in the fact that biological explanations of crime understate the important role of social conditions. (Conklin, p 93). When looking at biological and social combined, there is a moderately strong relationship between testosterone and social integration while growing up. Social integration can be fragmented due to less social opportunities by being in lower-class status, unmarried, and an unstable work history. (Conklin, p 96).

No one can be certain whether nature or nurture is the cause for criminal behavior. However, research has stated that it is more often an interaction between genes and the environment that predicts criminal behavior (Jones, 2005). Through a biological perspective, it is determined that criminal behavior is due to genetics and/or neurological conducts. It concludes that criminals are born due to their criminal traits being passed down through genetic or chromosomal mutation. Another explanation of criminal behavior within the biological perspective are the neurochemicals within our brains and body. There many regulated chemicals in the brain that determines thought process, perception and action. Like the arguments for genetic and chromosomal mutation, any abnormal anomalies or chemical imbalance can heavily impact behavior (Schram, 2018). This goes for any damages to some parts of the brain that controls emotions, reason and logic. Problems with the biological perspective are the following: 1. It provide little explanations for a small of minority of offenders with specific conditions (Levitt, 2013). 2. Disregard the effect of environmental influences and life experiences that also impact behavior. 3. Since criminality is based on biology, it is unchangeable, therefore, no one is to be blamed for their actions. Lastly, 4. Famous studies on biological factors of criminality (ex: the twin, family and adoption studies) maintained an intertwined relationship with social

The objective of this study is to examine whether it is nature or nurture who plays the most vital role in a human’s behavior, specifically an individual’s criminal behavior. Criminal behavior is defined as an act or failure to act in a way that violates public law. Some believe that criminal behavior can be identified as early as conception, meaning that criminal behavior is because of your genes. While others believe that one’s upbringing and social learning environment directly contributes to the individual’s criminal behavior. This paper will provide the history on the ongoing debate of nature vs. nurture and answer the question of whether it is

The biological theories are an essential to criminal justice professionals to explain why the genetic characteristics of the human being's body chemicals and evolutionary aggressive criminal conduct have been proposed as explanations for crime; however, to distinguish criminals from non-criminals without adding the value judgment. (Bohm & Vogel, 2011) “Biological theories can be understood as a broad, science-based, anthropological approach to understanding criminality” (Swan, 2017, para. 4). It is important to understand the body type based on the functions of the brain. Therefore, there are several different methodologies to describe the physical differences between criminals and non-criminals such as physiognomy, phrenology, criminal anthropology, the study of the body types, heredity, and scientific technologies that examine the brain function and structure to give the criminal justice profession another look into an individual before a biased take.

Criminals are born not made is the discussion of this essay, it will explore the theories that attempt to explain criminal behaviour. Psychologists have come up with various theories and reasons as to why individuals commit crimes. 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.

The principles of the biological theories allow us the understanding that all biological theories should evaluate common factors that relate to each other from one biological theory to the other (Schmalleger, 2012). The first parts of the biological theory assess the importance for the theories to make a connection between criminal behavior and the human brain and a person’s personality and the studies of neurology and neurochemistry. This meaning that a person’s ability to control antisocial behavior stems from their environment and the and family genes gives the person directly into right and wrong. There is also a standard that should evaluate the connection between different groups such a sex and racial makeup that that of criminal behavior as well as human instinctive behavior (Dretske, 2014). The link between the evolutionary development of a person criminal behavior or ability to

Genetic influences on behavior can affect the criminal justice system. If a person is convicted of a crime with a mental disorder they have diminished responsibility for the crime and may not be held accountable because of their behavior and since this is the case should then genes affecting your behavior be treated the same way(“Genetics and Human Behaviour: The Ethical Context”).

Another study that has been done was with separated twins. Each twin was raised in a completely different environment than the other. Genetically, they were both identical in every way, but the environment that they were raised in was very different. One twin was raised in a very hostile setting and slowly became violent as an adult while the other twin was

Researchers have also looked at criminal behavior from a genetic aspect. In fact, "behavioral genetic research has show that genes influence individual differences in a wide range of human behaviors -cognition, academic achievement, personality and temperament (including such traits as aggression and hostility), psychopathology, and even vocational interests and social attitudes" (Meadows, 2010, P.16). There may in fact be a connection between how an individual is wired and the behavior that results. This does not necessarily mean that some individuals are inevitably going to become a criminal. However, some individuals may simply have a greater tendency "to be more aggressive and thus less likely to control emotions absent some type of positive interventions" (Meadows, 2010, P. 16). Furthermore, genetic research looks at the heritability of certain disorders and specific genes that

According to the article "My Genes Made Me Do It” by Stanton Peele, Ph.D, and Richard DeGrandpre, Ph.D, “The goal of determining what portion of behavior is genetic and environmental will always elude us. Our personalities and destinies do not evolve in this straightforward manner” (Peele). Many factors can influence behavior, and behavior is not simple. It is very complex and can in some cases cause people to behave criminally. There are genetic factors that can influence a person’s behavior as well as environmental factors. All of these factors should be considered when looking at criminal behavior. The factors that affect a persons likelihood to commit a crime include genetic and environmental influences, but there are ways to prevent crime.

Behavioral neuroscience or biological psychology employs the principles of brain pathology to the study of human behavior through genetic, physiological, and developmental operations, as well as, the brain’s capacity to change with experience. Since the second world war, crime was largely attributed to mostly economic, political, and social factors, along with what psychologists termed at the time, the “weak character” of mental disturbance, and brain biology was rarely considered. However, new advances in neuroscience and technology have allowed a number of studies that link brain development, impairment, and injury to criminal violence. This emerging field of psychology explores the brain at a microscopic level, focusing studies on the roles that the brain’s neurons, circuitry, neurotransmitters, and basic biological processes play in defining and molding all human behavior.

20). This illustrates that not only is persons' genetics contributing to criminal behaviour 'but' also the environment in which the they are socialised can initiate deviancy.
