2 AGGRESSION - What is aggression? Imagine you are writing a dictionary for GCSE psychology students. How could you explain aggression? When we have discussed your responses make sure you have written a good definition in the glossary. Now read the following examples and state whether you think they are aggressive acts or not: A woman shouts at her boyfriend in the street for looking at another woman; A soldier shoots an enemy dead; A driver gesticulates at another on the motorway for pulling out in front of her; A young boy spits on another as he walks past; A man pushes his wife because she gets in his way. Aggression can be physical It can also be verbal Can you think of some examples of both? In this topic we will focus on the kind of aggression that is intentional and destructive. What causes this behaviour? What role do parents play? How can aggression be reduced? Biological explanations Do you think that people are born with an aggressive manner, or do they learn it as a result of their environment? : Before you go on, write down what you think makes a person aggressive. Try to think of four or five different explanations. 2

3 From a biological perspective, researchers have looked at the role of the...,... and... in aggression. They believe that these are important factors in our biology that can affect our behaviour. The Brain - Part of the brain called the... influence things such as..., and... - The part of the brain that controls the behaviours and stops us being aggressive is the affecting both these parts of the brain may lead to abnormally high levels of aggression. Case study of aggression Charles Whitman climbed up the clock tower at the University of Texas on August 1, 1966 and shot 12 people with a high-powered rifle. He had also killed others including his mother, and left a letter asking for his brain to be examined after his death, to find out what was making him kill. A post mortem revealed he had a tumour pressing on the part of his brain that causes aggression, the amygdala in the limbic system. Clip of shooting Letter from Charles Whitman How does the example of Charles Whitman support the idea that aggression could be due to a person s biology? Can Charles Whitman be held responsible for his behaviour? How do you think the law should treat people who are violent if it is not their fault? Write down your answers. 3

4 The biological approach also indicates that the higher levels of certain chemicals or hormones are linked to aggression. For example: Hormones Males are Males have more than females. As a result, this hormone is thought to be the cause of This has been supported by findings that have higher levels of testosterone than. Chromosomes Humans have in each cell, half of which we inherit form our mothers and half from our fathers. The 23rd pair, for instance, determines whether we are (XY) or (XX). If one of these pairs I damaged in anyway, or if we have more chromosomes than normal, we may show certain or may suffer with certain. Some occur spontaneously; others may occur if the mother while, for instance. It used to be believed that males with an extra chromosome in the (XYY) may result in the person being. These people tended to be extremely tall and male. This is not now found to be true. What other reason do you think may have caused the abnormal behaviour in this group of people? 4

5 PSYCHODYNAMIC EXPLANATION The main focus of this approach is that aggression is innate (inborn). One of the explanations put forward from this Approach is the frustration-aggression hypothesis. Freud suggested that we have an unconscious drive that causes aggressive behaviour. Our aggressive behaviour is caused by an internal force, or instinct, which he called Thanatos. It is this that drives us towards selfdestruction. All the time this instinct is building up inside us, it creates pressure, until sooner or later we cannot control it and it makes us do something aggressive. Dollard et al (1939) argued that, although we might have an aggressive instinct building up inside us, Freud was wrong to suggest that it would suddenly spill over into aggressive behaviour for no reason. They said it needed something to trigger it off. They proposed the frustration-aggression hypothesis. People are motivated to reach goals but, if they are blocked, then frustration occurs. EXAMPLE: if a task is too difficult or someone stops us from doing something we will become frustrated and then, because we are frustrated, we behave aggressively. Can you think of an occasion when you were frustrated? Did it result in you behaving aggressively? This explanation argues that aggression may be delayed or directed onto a target other than the cause of the frustration. An example of this is scapegoating, when aggression is turned onto an individual or group that is not the cause of frustration but is a safe target, because it is less powerful and not likely to retaliate. Read the following scenario and identify the scapegoat; Nicholas has had a bad day at work. He was supposed to meet his target of selling a certain number of ice creams But it has been raining all day and people haven t been to the beach where he parks his van. On his way home the car in front of him is driving very slowly; Nicholas beeps his horn and shouts at the driver as he overtakes. 5

6 In groups see if you can come up with an example of someone experiencing frustration through a blocked goal which, then leads to an act of aggression on a scapegoat. Not everyone who experiences frustration goes on to behave aggressively, can you think of reasons why? Make a note of these on some rough paper first So, what can we conclude about the relationship between frustration and aggression? Frustration... What other feelings, other than aggression do you think that frustration might lead to? KEY STUDY Berkowitz (1968) Aim: Can people learn to associate stimulus such as guns with anger or releasing anger? Method: 6

7 Results: Conclusion: RESEARCH METHODS What research method does Berkowitz use? What is an advantage of using this method of investigation? What is the independent variable in this research? What is the dependent variable? Write a hypothesis for this investigation 7

8 Social learning explanation of aggression Social learning theory suggests that aggressive behaviour, like all other types of behaviour is caused by people seeing how other people behave, and copying it. As people experience new situations, they look to other people for guidance as to how they should act. This is called. For children, there are lots of new situations, so they are more likely than adults to copy what they see. This is know as. Social learning theory stresses the importance of indirectly learning through the experiences of others. This is called. We can learn new ways to behave just by watching what other people are doing. Can you identify some behaviours which are learned by children this way? Who s behaviour do you think they will imitate particularly? These people are called role models Who have been the role models in your life? The most important factor in whether we imitate behaviour or not is if we see the behaviour reinforced. Reinforced means... If a child sees the behaviour reinforced, it creates an expectation that they will be reinforced for the behaviour if they imitate it. It is this expectation that motivates the behaviour. 8

9 Identify how aggression can be learnt using the example of a child watching a film where the hero defeats the baddy by hitting him. Use the following words in your response: Monitoring, vicarious learning, role model, imitates, reinforcement. KEY STUDY Bandura (1961) Aim: Method: Results: Conclusion: 9

10 RESEARCH METHODS Read the investigation conducted by Patterson (1967) on page 168 of the text book. Identify what method of investigation is used. Now identify one advantage of using this method of investigation. Now identify one disadvantage of using this method of investigation. How does reinforcement explain why aggressive behaviour might take place in one situation not in another? In Read the information provided on real life cases. Do you think that social learning theory suggests that the media have an effect on aggression? You will have heard of cases where people have injured others and said that they were imitating a character in particular film. Do you think this could be true? In groups Suggest arguments for and against. WAYS OF REDUCING AGGRESSION 10

11 One of reasons for studying aggression is to identify ways in which it may be reduced. Biological approach suggests that aggression could be reduced through the use of surgery or chemicals. In groups discuss as many abnormal behaviours as you can think of that are treated in physical way. EVALUATION The psychodynamic approach see page 171 of the course book. Sport provides an opportunity for : But Freud also argued that simply watching competitive sport was also : Freud also argued that the of aggression This involves transferring aggression and This is called a defence mechanism. To avoid aggression against others, this aggression should be directed at objects: According to Berkowitz, is more likely to lead to if there is an. KEY STUDY Baron (1977) 11

12 Aim: To test whether there were certain factors that could reduce aggression. Method: Results: Showed that in the first three conditions drivers showed than when the woman was dressed Conclusions: RESEARCH METHODS Barons study is an example of a field experiment. Give one advantage and one disadvantage using a field experiment. See page for notes. EVALUATION see page 173 of course book. Identify one negative criticism the psychodynamic approach suggest as a way of reducing aggression. 12

13 Identify one positive criticism the psychodynamic approach suggest as a way of reducing aggression. In groups, think of the activities you do for pleasure. Do you think they help you to release you aggressive urges? Make a list of all the things the members of your group do. Then put them in order of which you think will help you to cope with your aggressive instincts the best. If your list is similar to other groups lists, put a list of the top five activities on the wall, together with an explanation of how they reduce aggression in people. The social learning approach to reducing aggression. See notes on page 173. According to social learning theory, and Bandura s research, if we see models for aggressive behaviour we should be But seeing models can also aggression. EVALUATION See notes on page 174 course book. Identify one problem of using punishment as a way of reducing aggression. Identify one way in which social learning theory has been useful in reducing aggression. SLT advises that, to reduce aggression, children should not be exposed to aggressive role models on television. Freud would advise that, through catharsis, watching aggressive role models will reduce aggression. Which of these two views seems right to you? Divide yourselves into two groups and have a debate about this issue. Glossary - write a definition for these key terms 13

16 Do you know the main features of these explanations of aggression? Biological, including the role of hormones, brain disease and chromosomal abnormality Psychodynamic, including the frustration-aggression hypothesis Social learning, including modelling, punishment and monitoring Examiners tip: This requires an understanding of theories, not studies. The next section requires an understanding of studies not theories. It is important to understand the difference between these two terms. Can you describe and evaluate studies of the development of aggression? This includes studies based on the following approaches: Biological Psychodynamic Social learning Examiners tip: Remember, when evaluating studies, you can make positive as well as negative comments. Can you describe ways of reducing aggression, based on these explanations? Biological Psychodynamic Social learning Examiners tip: Remember, the methods you describe must relate to the explanation named in the question. Can you evaluate the ways of reducing aggression based on these explanations? Biological Psychodynamic Social learning Examiners tip: You can suggest why these ways are successful or unsuccessful. 16
