Therefore low levels of serotonin may lead to increased susceptibility to impulsive behaviour and aggression. Abstract. It prevents stimulation of the amygdala found in the brain’s limbic system, which when stimulated increases aggressive behaviour One test, therefore, is whether human neural crest cell biology exhibits similarities to … • The role of Genetic factors in aggression.

(8 marks + 16 marks) You should outline and evaluate the link between aggression and neurotransmitters such as serotonin and dopamine, and hormones such as testosterone and cortisol. The role of high testosterone. Found insideFindings show that neural processes underlying violence are complex and that there is no single mechanism in the brain that causes violence. The Role of Neural and Hormonal Mechanisms in Aggression . Formed from several structures in the brain including the amygdala and the hippocampus, concerned with motivation, emotion, learning and memory as well as instinctive behaviours such as aggression. 1 of 25. Serotonin – Psychologists believe that low levels of serotonin, known as the body’s natural ‘happy drug’, can lead to an increase in aggression levels. The use of model biological systems has been an important tradition in the study of neural mechanisms of learning. Serotonin and dopamine. StudyWise: A-Level Psychology Revision Outline and evaluate neural and/or hormonal mechanisms in aggression. Neural Mechanisms in Aggression and Aggressive Behaviour Agressive behaviour is that kind of behaviour when a person is very angry and has the intention to destroy, hurt something or someone.

This book brings together an international group of leading authorities to advance specific, testable hypotheses about the causes of conduct disorder and juvenile delinquency. suggest that the neural mechanisms involved in emotion regulation and cognitive control mediate the relationship between deficient self-control and aggression. 2234. There is also a less established link between dopamine and aggression. Like all behaviors, aggression represents the outcome of sets of biological and physiological processes emerging from the brain. Violent acts have a significant toll on human societies: annually over 1.6 million deaths worldwide occur due to human violence (Viding & Frith, 2006). The link between neural mechanisms, such as serotonin and dopamine and aggression can be criticised as being reductionist.
