Still others blame criminal behavior on the hierarchal make-up of society. that laws are specifically made by the aristocracy to rule over those in the lower social classes. Psychological factors and cognitive development also have been theorized to play a role in criminal behavior. The answer could be one or a combination of these theories. All economically deprived persons aren’t criminals and those that believe life has treated them unfairly or who have grown up around crime as a way of life, though they may be pre-disposed, do not necessarily resort to crime. This discussion briefly explains these theories for criminal behaviors in an attempt to display their similarities and differences and concludes with thoughts regarding how they may intertwine supplementing each other as an explanation.
Among the biological and physiological explanations for crime is the Behaviour Genetics Theory which postulates a biological explanation for crime. While the genetic make-up of an individual does not induce any specific actions, anti-social behaviour can be facilitated by neurotransmitters in the brain and hormonal imbalances which generate tendencies to act in a particular way. “Low self-control is strongly and inversely related to the neurotransmitter/neuromodulator serotonin, and that serotonin level is heritable” (Robinson, 2004). Abnormal serotonin levels have been shown to be an origin of criminal behaviours of all types of crime because an individual lacks the natural ability to control their impulsive thoughts thereby acting upon them. Everyone has thoughts they would never act upon. Those with this abnormality tend to act first and think later. Evidence compiled from studies has supported another link between a particular inherited mutant gene and criminal behavior.
