The role of sex hormones and brain activity in risk-taking and antisocial behaviour in adolescence
While there are a number of reasons to hypothesise that circulating testosterone performs an important role in many risky behaviours, the findings of empirical studies remain unclear. It is likely that testosterone levels interact with other factors in the environment and may be the consequence of behaviour as well as a cause. In this project students might measure levels of circulating testosterone in saliva and examine their function in contexts such as antisocial behaviour (aggression, delinquency), risky driving behaviour, or in sports performance. This work will happen in parallel to investigating the neural mechanisms, using EEG, that may mediate circulating testosterone effects on cognition and behaviour.
