Unit 6: Criminal Psychology Flashcards
What are the causes of criminal behaviour?
nature (genetics)
nurture (upbringing)
What is social learning theory?
adaptation of behaviour to match your social circle (observation and imitation)
What is operant conditioning?
learning from the consequences of your actions
How can criminal behaviour be learned?
from being rewarded or from imitations
What did Skinner (1948) do?
he developed the operant conditioning theory. he believes there are 2 types of reinforcement (positive + negative). he used animals to show how they can learn behaviours with reward.
What does reinforcement do?
encourages us to repeat behaviours we have displayed
What is positive reinforcement?
receiving something pleasant for a behaviour so we repeat it again
What is negative reinforcement?
the avoidance of something unpleasant so we repeat it again
What is punishment?
consequence of bad behaviour aimed to teach them not to repeat it
What is positive punishment?
receiving something unpleasant for a behaviour so we don’t repeat it again.
it is adding a stimulus to decrease bad actions.
What is negative punishment?
removing something pleasant so we don’t repeat the behaviour again
What are primary reinforcers?
a reinforcer that satisfies a biological need.
committing crime for basic needs like food/water
What are secondary reinforcers?
a reinforcer of no survival value, but we have learned to associate it with a primary reinforcer
such as grades and stickers (have no survival value but learned to value itself)
What are reinforcers?
in positive reinforcement you gain something pleasurable to influence you not to repeat said behaviour again. the pleasurable things you get are reinforcers. Such as snacks, stickers and grades.
What are the strengths of the operant conditioning theory?
the theory can be used to explain a wide range of crimes
punishment can remove undesirable actions
What are the weaknesses of the operant conditioning theory?
it cannot explain all crimes, neglects personality type and genetics
some behaviours are produced without reinforcement/punishment, neglects other motivations to commit crimes
What is social learning theory?
behaviour is learned through the observation and imitation of role models
What is modelling?
learning through paying attention to a role model, retaining and reproducing it
What is the identification and modelling process?
ARRMI
attention, retention, reproduction, motivation, identification
What is vicarious reinforcement?
watching a role model getting rewarded for something and after observing them you are motivated to do it too.
What is a role model?
a person whom we admire and share similar characteristics to.
What are the strengths of the social learning theory?
lots of evidence to support theory (bandura)
observational learning main explanation of children behaviour
theory explains how those exposed to criminality become criminals
What are the weaknesses of the social learning theory?
such studies only measure short term effects on children
some behaviour can’t be explained through observational learning
What is the background to the Bandura study?
he was interested in sex-appropriate behaviour, children tend to be rewarded for sex-appropriate behaviour and punished for the opposite which are reinforced through childhood.
What are the aims of Bandura’s bobo doll study?
will children imitate aggression of a role model, will sex of role model affect children imitation, will sex of child influence likelihood of aggressive behaviour
What were the participants and sampling in Bandura’s bobo doll study?
72 children, 36 girls and boys each
all between 37-69 months and recruited from stanford university nursery
they were all randomly allocated to conditions
What type of experiment was Bandura’s bobo doll study?
laboratory experiment, independent measures design procedure
What is the procedure for Bandura’s bobo doll study?
What are the results for Bandura’s bobo doll study?
children exposed to aggro role model displayed more aggression than the non-aggro role model
boys more likely to imitate aggression from same sex-aggressive model, girls more likely to copy verbal aggression from same sex role model
girls spent more time playing with dolls and tea sets while boys played with guns (aggressive)
What is the conclusion of Bandura’s bobo doll study?
children learn through observation in the absence of reinforcement
provides evidence for social learning theory
children learn aggression from role models specifically of the same sex
What are the strengths of Bandura’s bobo doll study?
controlled environment and standardised procedure means replicable and reliable data
children matched in groups according to their normal aggression levels so data cannot be affected by specific children who are naturally more aggressive
What are the weaknesses of Bandura’s study?
unfamiliar environment and children might guess aims of experiment and give demand characteristics
researches exposed small children to aggression ignoring long term effects (breaks ethical rules by not protecting participants)
What is the background of Charlton’s study?
the island st helena was a small british colony which didn’t have access to TV (mainland television channels). charlton wanted to see the effect of TV on behaviour
What were the aims of Charlton’s study?
to investigate the effects of television on children’s behaviour, particularly aggression.
What was the procedure of Charlton’s study?
- researched went to the island in 1994
- recorded behaviour of children 4 months before satellite TV was introduce
- video cameras were to observe children (3-8 years) over a 2 week period
- researchers recorded 256 minutes of children freeplay and their playground behaviour
