Biological And Psychological Perspectives On Genetic And Mental Disorders

1. Describe and the biological and psychological factors that contribute to crime and deviance within our society today. There are many factors that suggest that abnormal human traits tend to lead someone to the life of crime. The trait theories are divided into two groups – biological makeup and psychological ideals. The biological makeup tends to say that they the physical and mental makeup of someone tends to make them either lead a life of crime or know the difference. Cesare Lombroso studied “scientific” factors of crime and came up with some very interesting theories about the mental/physical aspects of criminal traits and activities.

Twin studies are a mainstay of the nature verse nurture debate because they allow researchers to conduct “natural experiments” on human beings. When researchers try to determine the relative importance of genetics and environment with regard to a certain condition, they have a hard time because they cannot generally get people with the same genes. This is where twin studies come in. Twins studies are part of the method used in behaviour genetics, which includes all data that are genetically informative. E.g. siblings, adoptees, pedigree data etc. Researchers use this method to estimate the heritability of traits and to quantify the effect of a person 's shared environment (family) and unique environment (the individual events that shape a life) on a trait.

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 biological theories are essential to the criminal justice profession so that they won't assume that a person's genetic characteristics cause a person to commit a crime. However, there are born criminals and “these types of criminals are the most dangerous, and can be identified through his or her stigmata or identifying characteristics” (Akers, Sellers, See, & Kieser, 2013, p. 10). Biological theories are the bases for severe criminal behavior mostly found among people who are born with an innate impulse to commit a

Biological hypotheses of wrongdoing spotlight on the physiological, biochemical, neurological, and hereditary elements that impact criminal conduct. In any case, such speculations likewise stretch the overwhelming join between a man's science and the wide traverse of social or ecological components that sociological hypotheses analyze. For instance, the three noteworthy sociological speculations of wrongdoing and misconduct—strain, social learning, and control—all clarify wrongdoing regarding social natural variables, for example, the family, school, peer aggregate, working environment, group, and society. Be that as it may, sociologists likewise perceive the essentialness of natural, mental, and related hypotheses of wrongdoing and also the significance of individual attributes, for example,

First, psychological theory suggests that a person’s environment and past can influence their ability and desire to commit crime while biological theory suggest a person’s DNA makeup could influence their ability to commit crime. “Biological theories within the field of criminology attempt to explain behaviors contrary to societal expectations through examination of

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

People perceive that crime, primarily violent crimes, such as murder, is the most serious crime society faces in modern times. This has led to efforts by many research groups to attempt to find the cause of such criminal behavior. The focus of such research is biological issues with the belief that a biological basis in criminals does exist and that understanding biology is useful when attempting to predict the individuals who may be predisposed to criminal activity in the future. Research in the 1960s suggested that males with an extra Y chromosome

However, while the overstimulation of the Id and the failure to acquire and develop the the Ego and SuperEgo leads to criminal tendencies, while aggression may be out of adaptive values, and while genetic studies have pointed towards the influence of genes and criminal behaviour, these theories alone are insufficient to account for crime. Evolutionary theory does not explain or predict for the extreme degrees of aggression in individuals nor has the genetic theory proven for 100% heritability; which raises the need for us to examine the Nurture camp of crime theories as well.

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

Based on the information provided in the assigned readings, I believe that there is a significant role that genetics has in criminality. I think that it needs to be pointed out that an environment has an effect on the way that an individual is raised and behaves throughout their childhood, adolescents and adulthood; however, the environment itself should not be considered the sole reason why an individual would display antisocial behavior. For example, as described in the readings, biological factors such as the size of the individual’s brain, the heart rate of an individual, abnormal levels of testosterone, abnormal levels of serotonin, and abnormalities in an individual’s functions or senses of the body, to name a few, can be early indicators

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.
