Criminal Psychology Whole Unit Flashcards
Understanding learning theories as an explanation of criminality
- Learning theories explain behaviour as a result of the experiences that we have
- These theories suggest that criminal behaviour can be explained as a result of learning, like any other behaviour we display
- e.g. if we can learn to behave well in school because we see older peers behaving well or we are rewarded for good behaviour
- Similarly, criminal behaviour can be a result of being rewarded or we can come from modelling the criminal behaviour we see in others
Operant conditioning as an explanation of criminality
- Burrhus Frederic Skinner (1948) developed a theory of learning called operant conditioning
- He believed that behaviours we display are likely to be repeated if they are reinforced or extinguished and not repeated again if we are punished.
- Operant conditioning explains that there are two types of reinforcement - positive and negative. This is the consequences of which encourage us to repeat a behaviour we have displaced
- In operant conditioning there is reinforcement (which achieves desired behaviour) and punishment (which achieves desired behaviour)
- Reinforcements work well when given when the behaviour has been displaced
- Operant conditioning also explains that punishment is a consequence of behaviour, which means we are less likely to repeat behaviour again
Positive reinforcement in terms of criminal behaviour
- We receive a pleasurable or rewarding consequence for our behaviour
- We are then likely to repeat the behaviour to get something nice again
- In terms of criminal behaviour, if someone receives praise from their family for fighting or for vandalism, or financial reward from committing fraud, then they are likely to commit the crime again
Negative reinforcement in terms of criminal behaviour
- When a behaviour we display is strengthened by the avoidance of an aversive or unpleasant experience
- We are likely to repeat a behaviour that gets rid of something unpleasant
- In terms of criminal behaviour, if someone is able to stop a bully by punching them, it is likely that they will use their fists to solve problems in the future.
Positive punishment in terms of criminal behaviour
- Receiving negative consequence for a behaviour, such as a child being told off by a parent for not keeping their bedroom tidy
- This is often the way that we treat criminal behaviour
- If someone does a criminal act and is fined or imprisoned, they are being positively punished
Negative punishment on terms of criminal behaviour
- Taking away something pleasant as a consequence of a behaviour that is not desired
- e.g. if a child is disruptive at a birthday party, which they are really enjoying, a parent can remove them from the party to sit in the corner
- In terms of criminal behaviour a person may enjoy being part of a gang
- The gang may start to vandalise public property but because the person does not want to join in, they are told to leave the gang
- The undesired behaviour of not vandalising property is punished
Operant conditioning in prison
- The state uses both positive punishment and negative reinforcement
- e.g. if someone commits fraud and is put into prison, they are receiving positive punishment for their actions
- When they are released from prison, they should avoid committing fraud because they do not want to be imprisoned again: this would be negative reinforcement
Types of positive reinforcement
- Operant conditioning explains that there are two types of positive reinforcers that can be used as a consequence for behaviour to strengthen behaviour
- Primary and secondary reinforcers
Primary reinforcers
- These satisfy a basic biological need, such as food and water
- e.g. A parent may reward the child with food treats for behaving well
- Although it is unlikely that most criminals commit crime for primary reinforcers, people who are in extreme poverty or are starving may resort to committing a crime, such as theft, in order to satisfy a basic need.
Secondary reinforcers
- There are common reinforcers, such as school, grades, and tokens
- These reinforcers often have no survival value, but we have learned to associate them with a primary reinforcer
- e.g. a credit card
- The card itself has no intrinsic value but it can be used to buy goods which are rewarding or satisfy a basic need such as food and warmth.
Strengths of operant conditioning in terms of criminal behaviour
- A strength of operant conditioning is that the theory can be used to explain a wide range of crimes. For e.g. it explains theft and how social approval can be a strong reinforcer in peer groups that encourage deviant behaviour through positive reinforcement. It can also explain murders such that a man may find out that his friend is stealing from him, he attacks him, and the friend dies. This is negative reinforcement as it removes the aversive situation
- Operant conditioning also explains that punishment can remove an undesirable behaviour. The is used in our criminal justice system - offenders are punished through the removal of their civil liberties.
- It has also contributed to the development of behaviour management techniques such as token economies. These systems reward good behaviour in prison with tokens that prisoners can exchange for goods or treats.
Weaknesses of operant conditioning in terms of criminal behaviour
- A weakness of the operant conditioning explanation is that not all crimes are committed because of receiving reinforcement or punishment; it is often more complicated than that.
- It neglects other factors that can cause criminal behaviour such as the type of personality or genetics
- The behaviour can be reproduced in the absence of reinforcement or punishment. A big part of whether someone chooses to commit a criminal act can be due to the way they think or a different form of motivation than reward. if an employee feels as though they are not valued in their job, they may choose to steal stationary to get back at their employer.
Social learning theory
- Social learning theory is a social theory because it explains that we learn from one another, rather than directly from reinforcement or punishment
- Albert Bandura (1977) explains behaviour as a consequence of observing and modelling others around us
- This is known as observational learning
- We do not just copy anyone, we are motivated to copy those with whom we share similar characteristics. This person becomes a role model.
- From observing a role model, we can learn how to new behaviours are performed, this is known as modelling
- This may or may not lead to a change in behaviour
Modelling
Learning new behaviour through paying attention to, retaining and reproducing the behaviour of a role model
Observational learning
learning new behaviours through watching and modelling a role model
Role model
a person who we admire or with whom we share similar characteristics.
The identification and modelling process
- Attention
- Retention
- Reproduction
- Motivation
- Identification
Social learning theory as an explanation of criminality
- if a person is exposed to criminality, such as a child living in a violent household, then they are more likely to pay attention and retain this.
- Parents and television characters can be strong role models
- If a child is exposed to criminality they are ore likely to model the behaviour, particularly if the role model appears to be rewarded for their activities
Attention
in order to learn something new, you must be able to, and want to pay attention to it
Retention
- for learning to take place, you must be able to store or retain the new behaviour in your memory
reproduction
- to be able to model the new behaviour that you observed, you need to be able to reproduce it
- So you may watch a gymnast do a backflip, and you could have paid attention and retained the way in which the move was performed, but you will not be able to reproduce it without agility and practice
Motivation
- you are more likely to model a behaviour you have observed someone do if you are motivated to reproduce it
- This motivation can be intrinsic, in that you gain pleasure from copying it.
- It could also be that you see the role model receiving a reward for this behaviour os you copy it in order to receive the same reward.
- This is known as vicarious reinforcement
Identification
- identification occurs when you adopt behaviour, beliefs and values of the role model or group
- temporarily adopting the behaviour of a role model of group
Vicarious reinforcement
motivation to model the behaviours of other who we see being rewarded for their behaviour
strengths of social learning in terms of criminal behaviour
- There is a lot of evidence to support the social learning of aggressive behaviour. Bandura (1960s) conducted a series of experiments that exposed nursery-aged children to an aggressive role model. He found that aggression was copied, especially if the role model was the same sex as the child and if the role model was rewarded for their aggression
- Observational learning is one of the main ways that children learn new behaviour and can explain this behaviour in the absence of reinforcement. Some behaviour does not become learned through consequences
weaknesses of social learning in terms of criminal behaviour
- Although experimental evidence, such as the studies conducted by Bandura, shows how children learn aggressive behaviour from a role model, such studies can only measure the short-term effect. We cannot ethically test whether exposure to aggression can have long-term effects. Meaning that the theory cannot be tested in real-life situations
- Some criminal behaviour cannot be explained by observation learning. For e.g. murder is rarely witnessed in real life. It cannot explain opportunistic crime that has not been observed by the criminal. Similarly fraud is unlikely learning through observation as it is typically driver by financial gain.
Biological explanations of criminality
- Biological explanations of criminality do not take learning experiences into account
- instead, they explain criminality as a result of our biological systems, such as our brain and nervous system, genes and hormones
- Biological explanations have been used to explain criminality throughout the history of psychology
- Early theorists believed that criminals had certain body types and facial characteristics that indicated whether they were criminal and what type of crime they would be likely to commit.
Genetic explanations for criminality
- Studies have found that criminality runs in families
- However, such evidence is undermined by the possibility that upbringing might account for these finds or that a social factor, such as poverty, may explain the tendency for criminality to run in families
Twin studies for criminality
- If monozygotic twins are both more likely to be criminals compared to dizygotic twins then there could be some evidence that criminality has a genetic basis
- Karl Christiansen (1977) found that 35% of identical male twins recorded in Denmark were both criminals compared to 13% of non-identical male twins
- For female twins, the figures were 21% of identical twins and 8% of non-identical twins
- However, identical twins are likely to be raised in a more similar way than non-identical twins (especially if they are a different sex)
- This shared upbringing could explain the slightly higher percentage of identical twins who are both criminals compared to non-identical twins.
Adoption studies for criminality
- One way to rule out the potential influence of upbringing is to use evidence from adoption studies
- Here, the biological and adoptive parents are compared to the child in terms of whether they have criminal records
- Assuming that the child has been adopted at an early age, we can then assume that any similarity between the biological parent and child is inherited
- Barry Hutchings and Sarnoff Mednick (1975) found that 21% of adopted children who went on to commit a crime had a biological father who was convicted of a crime
- This was compared to 10% of children whose biological father was not convicted of a criminal offence but the adoptive father had a criminal record
- However we should be wary of interpreting this as a biological basis for criminality because it could be some other tendency or attribute that has been inherited, which may explain why some adopted children turn to crime.
Personality Theory
- Our personality is the set of characteristics that determine what we are like
- Characteristics and qualities that make up someone’s individual character
- Some personality theories believe that our personality is a temperament, which has a biological basis
- These theories can explain how some personalities are associated with being a criminal, while others are not
- They suggest that a criminal personality trait is caused by internal, biological factors
Hans Eysenck
- Developed a personality theory and studied different personality traits and suggested that certain characteristic could be more prone to criminality
- 1964
Eysenck’s personality traits
- extraversion/introversion
- Neuroticism
- psychoticism
extraversion/introversion
- two extreme ends of one dimension of personality
- extraversion is being outgoing and sociable and is at one end of the dimension
- On the other end is introversion which is being reserved and quiet
neuroticism
- this refers to the nervous disposition of someone
- If they are stable, then they are calm and do not over-react in situations
- If they are unstable they tend to be highly emotional and quick to over-react
psychoticism
- this is a personality trait that shows a lack of empathy towards others
Measuring personality
- Each personality trait can be measured using a questionnaire devised by Eysenck.
- Its called the Eysenck Personality Questionnaire (EPQ)
- Each question in the EPQ measures the specific trains of extraversion/introversion (E), neuroticism : Stable/unstable (N), and psychoticism (P) which gives them a PEN score
The biological basis of personality in criminal psychology
- People with a high E score on the EPQ are believed to have a nervous system that has a low arousal level, so they seek external stimulation to raise their biological arousal level
- They do this by being outgoing and sensation-seeking.
- People with low E scores are believed to have a nervous system characterised by high arousal, so they avoid thrill and excitement in order to dampen their biological arousal level
- Unstable neurotics have a high N score and are believed to have a nervous system that responds very quickly under stressful conditions; they tend to over-react quickly
- In contrast, people with low N scores have an unreactive nervous sytem, meaning they are calm under stressful conditions
- Although Eysenck was less clear about the biological basis for psychoticism, he believed it was also linked to our biological make-up
- Having a high P score means that a person is cold, lacks compassion, and can be antisocial
Monozygotic twins
- twins developed from one fertilised egg that has split into two
- genetically identical twins
