Daly and Wilson (2001) – ‘Risk-taking, intrasexual competition, and homicide’, Nebraska Symposium on Motivation 47, 1-36.

Background

This is the third study we look at from the ‘Biology’ section of ‘Turning to Crime’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘Gender.’

Daly and Wilson’s study focuses on gender differences in criminal behaviour. Typically there is an 80/20 spilt between the males and females who are convicted of committing crimes.

There are many explanations offered for this unequal gender divide in crime, including evolutionary explanations and social explanations.

The study took place in Chicago which has around 77 different areas, all of which have varying levels of social and economic prosperity.

Brunner et al,. (1993) – ‘Abnormal behaviour associated with a point mutation in the structural gene for monamine oxidase A,’ Science 262 (S133), 578-80.

Background

This is the second study we look at from the ‘Biology’ section of ‘Turning to Crime’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘Genes and Serotonin.’

How much do genes and neurotransmitters contribute to the development of criminal behaviour? As this study is from the biological section, you may not be surprised to find out that genes and serotonin are central to the study. “Studies of aggressive behaviour in animals and humans have implicated altered metabolism of serotonin, and to a lesser extent dopamine, and noradrenaline [also known as norepinephrine] .
