Document Summary
Introduction: many criminogenic theories postulated biology to be the single casual agent for crime. Gall believed that a criminal could be identified by the shape of the skull and phrenology developed a massive following. Politicians abused the public"s lack of understanding with appalling consequences. Nature and nurture: the way a child"s personality responds to the environment is based on the child"s biology, puberty often results in behaviour changes and mood swings in adolescents. Adoption studies: the biggest concern with twin studies is the similarity of environments in which the twins live. The brain: criminal behaviour may be controlled by various factors, such as impulsivitiy, an inability to understand consequences, the need for immediate gratification, lack of empathy, anxiety, depression, or reduced cognitive ability. Serotonin dysfunction can lead to an increase in impulsiveness: dopamine is a neurotransmitter that creates the pleasurable sensations when we eat, experience feelings of love, and ave sex.
