I believe that human emotion is determined by the “hard wiring” of the brain. One good example is the criminal intent of particular individuals. It is actually interesting to know that anthropological research data shows that violence is an inherent conduct among the primate species (Walker, 2001). In society,
In the past few decades, neurobiologists have proposed that an individual’s condition, which encompasses empathy, morality and free will, is holistically influenced by the frequency of stimulation and assembly of the neurons of an individual. Such notion is contradictory to the concept of Cartesian dualism, which states that the brain and the mind are two independent entities that coordinate with each other.
To date, the accumulation of research reports from the field of neuroscience is gradually affecting the concepts and effectivity of the justice system because of the shifting in the concept of human behavior and response to different stimuli. Neuroscience has influenced our current understanding of the multiple factors that govern violent behavior among criminals. The 19th century classic report of Phineas Gage regarding the anti-social behavior that emerged after massive damage of the prefrontal cortex of his brain from a railroad accident is now considered as the birth of the field of forensic neurology (Harlow, 1848).
Today, computerized imaging of his fractured skull has shown that the autonomic and social nerve systems are the specific damages that were affected, thus resulting in a totally different individual. Such observation, together with research results gathered from war veterans, has led to the conclusion that violent criminal behavior is caused by injuries to the frontal lobe of the brain. It has then been proposed that injury to the prefrontal cortex of the brain causes a condition that has been coined as acquired sociopathy or pseudopsychopath (Blair and Cipolotti, 2000).
It is interesting to know that there is an 11% reduction in
The connection between the decreased expression of the monoamine oxidase A enzyme and reactive violence has already been established (Caspi et al. , 2002). Monoamine oxidase A is responsible for the catabolism of monoamines such as serotonin (5-HT). The working hypothesis currently accepted is that the prefrontal-amygdala connection is altered, resulting in a dysfunctional aggressive and violent behavior, resulting in criminality in particular individuals. The self-control theory as proposed by Gottfredson and Hirschi (1990) couples an argument regarding the driving force behind criminality and the features of a criminal act.
Gottfredson and Hirschi contend that crime is similar to other out of control and unlawful actions such as alcoholism and smoking because it generates in an individual a temporary yet immediate feeling of gratification. This kind of action is created by a condition that is characterized by low self-control. The authors claim that the condition of having poor self-control is an innate condition that is set in place during the early childhood at around 7 or 8 years of age. In relation to the mechanism behind criminality, the authors explain that crime is a straightforward action to results in gratification in an individual.
Such perception of crime is associated with a number of implications to the general theory of crime. Firstly, the general theory of crime presents that crime is an uncomplicated action that does not need any strategic preparation or intricate knowledge. Secondly, the general theory of crime is related to a number of elements that are included in the theory of routine activities because just like other uncontrolled acts, crimes are not planned and it is easy for individuals with low self-esteem to be easily motivated to commit such acts.
In addition, criminality is strongly influenced by external factors such as the scarcity of easy targets as well as the presence of associates that are capable of helping or even performing a criminal act. The theory of crime by Gottfredson and Hirschi regarding the early age of 7 or 8 also entails that the longitudinal analysis of crime is not necessary and that age-correlated theories of crime are confusing. The general theory of crime of Gottfredson and Hirschi also considers the fundamental argument regarding age and the unlawful act.
It is actually different from what is presented at general courses in criminology regarding the analysis of age-crime correlations and social factors that are related to crime. A distinction of the general theory of crime of Gottfredson and Hirschi is that the age-crime linkage is very different through time, location and culture that the age-crime correlation is irrelevant of any social explanation. Their general theory of crime also describes that criminals continue to perform unlawful acts of crime even during marriage and eventually end up as unmarried criminals.
The same thing goes with offenders who are currently employed—these individuals generally continue on as offenders and the only difference after some time is that they lose their jobs. The general theory of crime of Gottfredson and Hirschi thus presents an argument against the connection of crime with marriage and employment thus showing that a criminal is incompetent in maintaining a relationship in a marriage or a commitment to work because he is commonly known as person of very low command of his control.
Their presentation of the force behind criminality is thus focused on self-control and the authors point out that most investigations regarding criminality do not include this concept.
