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?
ACTIVITY:
Before you go on, write down what you think makes a person aggressive. Try to think of four or five
different explanations.

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.

ACTIVITY
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.

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?

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 self-
destruction. 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.
ACTIVITY
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.

ACTIVITY
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.
ACTIVITY
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?

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.
ACTIVITY
Can you identify some behaviours which are learned by children this way?
Who’s behaviour do you think they will imitate particularly?
ACTIVITY
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.

ACTIVITY
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.

WAYS OF REDUCING AGGRESSION
RESEARCH METHODS
ACTIVITY
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.
______________________________________________________________
_
ACTIVITY
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.
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.
ACTIVITY
In groups discuss as many abnormal behaviours as you can think of that are treated in physical way.

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)

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:
___________________________________________________________________________
___________________________________________________________________________

EVALUATION – see page 173 of course book.
Identify one negative criticism the psychodynamic approach suggest as a way of reducing aggression.
RESEARCH METHODS
Barons study is an example of a field experiment.
Give one advantage and one disadvantage using a field experiment.
See page 71-72 for notes.
13
Identify one positive criticism the psychodynamic approach suggest as a way of reducing aggression.
ACTIVITY
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.

ACTIVITY
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.

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
Can you describe and evaluate studies of the development of aggression? This includes studies based
on the following approaches:
◊ Biological
◊ Psychodynamic
◊ Social learning
Can you describe ways of reducing aggression, based on these explanations?
◊ Biological
◊ Psychodynamic
◊ Social learning
Can you evaluate the ways of reducing aggression based on these explanations?

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.
Examiners tip: Remember, when evaluating studies, you can make positive as well as negative comments.
Examiners tip: Remember, the methods you describe must relate to the explanation named in the question.
Examiners tip: You can suggest why these ways are successful or unsuccessful.
