The Biological reasons for aggression. New Title The Biological reasons for aggression.
The biological part… There are two areas of the brain that we need to look at. The Limbic system & Amygdala
The Limbic System The limbic system lies in the middle of the brain and is the area responsible for emotions such as survival, fear and aggression.
The Limbic System Additional Facts People with emotional disorders have been shown to have damage to their limbic system! The limbic system is made up of many structures that are jointly responsible recognising, controlling and producing aggression!
The Amygdala The amygdala is the part of the brain that recognises emotion – reading body language
The Amygdala The amygdala is the part of the brain that recognises emotion – reading body language
The Amygdala For example if someone smiles, we know they are happy and if they frown we know they are sad. When you see a frightened cat with its teeth showing and back arched this is amygdala showing its fear response.
The Amygdala ANIMAL STUDIES There is evidence that the amygdala is responsible for producing aggression. In animal studies they found that when the amygdala was removed the animals were calm and did not respond to threatening situations with aggression. Also damage to this part of the brain can cause increased levels of aggression.
The Amygdala HUMAN STUDIES Some studies have been done using humans… King (1961) described a case of a women whose amygdala when electrically stimulated during an operation which caused her to become threatening and verbally aggressive until the electrical current was turned off! In 1966 at Texas University Charles Whitman killed 13 people after he had killed his wife and daughter. He left a note asking doctors to examine his brain as he believed that something was making him overly aggressive. It was found that he had a brain tumour which was pressed against his amygdala!
Questions 1. What are the difficulties of researching human brain biology? 2. What are the strengths and weaknesses of the research conducted linking biology and aggression? Read page 95 and answer the questions in your book.
Homework Draw or print a picture of the brain highlighting the limbic system and amygdala and annotate (make notes) around it with evidence for a role in aggression from humans on one side, animals on the other.
