Document Summary
Chapter 3- origins of criminal behaviour: biological factors. Many male children exhibit high levels of physical aggression in preschool. But show significant reductions of these behaviours as the school years progress due to effects of socialization and parenting. Social environment is the most important determinant of criminal behaviour. How much antisocial behaviour is influenced by genes. Deciding which specific genes cause anti social behaviour. Biopsychologists (psychologists who study the biological aspects of behaviour. Try to determine which genetic and neurophysiological variables play a part in criminal behaviour. Focus on examining the role genetics play in the formation and development of human and animal behaviour. Studies the structure and function of genes at the molecular level. Study how genes are transferred from generation to generation. From two different fertilized eggs, like siblings. Chorion is the outer membrane enclosing the embryo. Therefor some identical twins develop in slightly different prenatal environments. Monochrionic are more similar in personality and cognitive than dichorionic.
