Criminal Behavior Essay -- Biology, Ellis and Walsh

Many scholars have attempted to explain reprehensible conduct by identifying a familial trait or other biological causes or indicator for criminality (Cullen and Agnew, 2011). Ellis and Walsh (2011) argue that while there is not a single criminal behaviour heritable trait, there are genetic trait that are associated with crime. They further suggest that these traits might provide evolutionary advantages to their holders in some circumstances. For example, traits such as deception and cheating would likely be evolutionary advantageous to maximizing a males reproductive capabilities. Ellis and Walsh suggest that these traits might be genetically inherited. This theory of genetic influence does not however suggest that behaviours are genetically determined. Behaviours are still assumed to be learned, with specific genetic traits influencing this process (Ellis and Walsh, 2011).Rowe (2011) suggests a too biologically driven theory. He argues that through their impact upon the central and autonomic nervous systems, genetic traits and biological harms can influence personality traits including those which are associated with criminality. In support of this notion are studies that have linked levels of testosterone and aggressiveness, low heart rate and criminality, weak skin conductance and criminality, as well as brain scathe and lack of moral judgement (Rowe, 2011).Caspi, et al. (2011) present the theory that there are three super-traits which have various relationships with crime. The three super-traits they discuss are constraint, negative emotionalism and positive emotionality. They note that the constraint and negative emotionality super-traits are related to self-control and with it criminality. This suggests that some indi... ...larly intimates. Both the methods and attributes associated with the crime are suggested to be learned. Learning of criminal and anti-criminal behaviour is thought to be similar to learning of other behaviours and attitudes in which the learner assimilates into the culture they are surrounded by (Sutherland and Cressey, 2011). This theory is similar to the Shaw and Mckays comment for criminality, but also ventures into the methods by which the attitudes are actually developed. Andersons description of a culture of violence, that establishes a code of the street provides a vivid example of both(prenominal) the environmental conditions described by Shaw and Sutherland and Cressey as well as the learning processes described by Sutherland and Cressey. These clearly environmental and learned factors somewhat weaken the arguments of biological causes presented earlier..
