- 3What is the role of the limbic system?*There are several parts to the limbic system, located deep in the central area of the brain.
*However, the Amygdala plays a main role in aggression: it is said to be a good way of being able to predict someone's aggressive behaviour. - 4Describe some evidence to support the limbic systemGospic et. al
Procedure
*He provided support for this ideas using the ultimatum game.
*Participants asked to take money someone has split with them or leave it.
*Sometimes participants were given unfair splits.
Findings
*When pps rejected unfair offers their Amygdala were highly active.
*Also when pps given a benzodiapine drug (reduces arousal of ANS), halved number of rejections and decreased activity of amygdala.
Conclusion
*Amygdala highly linked to aggression. - 5What does serotonin do?Serotonin is a neurotransmitter that exerts a calming effect on the brain, inhibiting neurons from firing. Lower levels of serotonin are associated with less control in relation to aggressive responses. This has led to the claim that low levels of serotonin are linked to impulsivity and explosive acts of violence.
- 6What does testosterone do?*The male hormone testosterone is involved in the development of masculine features such as: muscles, facial hair ect.
*It also has a role in regulating social behaviour which has been supported in several animal studies in several different species to have an impact on levels of aggression - Virkkunen et al.
*Some evidence of this has been found in human population - found positive correlation between testosterone levels of criminals and their aggressive behaviour. - 7Evaluation
