L1 - Theories of Crime Flashcards
(92 cards)
What is a theory and who’s definition is used here?
Any description of an observed aspect of the world that may consist of a collection of inter-related laws or a systematic set of ideas - (Kukla, 2001)
What are 7 features of theories that they can be appraised on?
- Predictive accuracy and scope
- Internal coherence
- External consistency
- Unifying power
- Fertility/heuristic value
- Simplicity
- Explanatory depth
What is predictive accuracy/scope in relation to theory appraisal?
Whether the theory can account for existing findings
What is internal coherence in relation to theory appraisal?
Whether the theory can be falsified
What is external consistency in relation to theory appraisal?
Whether it’s consistent with other psychological knowledge.
What is unifying power in relation to theory appraisal?
Whether it unifies different aspects of research in innovative ways.
What is fertility/heuristic value in relation to theory appraisal?
Whether the theory can make new predictions/treatments etc.
What is simplicity in relation to theory appraisal?
Whether it makes few assumptions or not. An ineffective theory would contain many, special assumptions.
What is explanatory depth in relation to theory appraisal?
Whether the theory can describe deep, underlying mechanisms.
What is a psychological theory in relation to Forensic Psychology?
Explains why some individuals go on to commit crime, while others don’t. E.g. specific behaviour traits common among offenders -why do some people develop these traits and some do not?
Describe the sample in the 44 Thieves study.
44 juvenile thieves and 44 control youths
Describe the results in the 44 thieves study.
40% of juvenile thieves had experienced separation of 6 months or longer.
Only 2 individuals in the control sample had experienced separation of this length - just 4.5%.
1/3 of juvenile thieves were described as having affectionless personality
None of the control group were described as having an affectionless personality.
What are 4 weaknesses of the 44 thieves study?
- small sample
- retrospective acocunts
- inadequate control group - may have committed crimes but have not been caught
- lack of control for extraneous variables (effect of foster homes, etc)
Which studies demonstrated the effects of early separation on conviction rates?
- Newcastle Thousand Family Birth cohort study (Kolvin et al., 1988)
- Cambridge study (Farrington et al., 2009)
What did Kolvin et al (1988) demonstrate about the effects of early separation on conviction rates?
If you have experienced maternal deprivation or privation (parental divorce or separation), the risk of conviction is doubled (up to age 32).
What did Farrington et al (2009) demonstrate about the effects of early separation on conviction rates?
60% of boys who had been separated from their parent(s) before turning 10 were convicted before the age of 50. This is compared with 36% in boys who had not experienced separation.
What did Juby and Farrington (2001) show about separation?
That it may not just be about separation, but also what happens after. Much higher conviction rates if childhood has been disrupted, but the mother is not present, compared to when the mother is present.
According to Ward et al., (1996), which attachment styles link with specific types of offending?
Rapists and violent offenders are linked with having dismissive avoidant attachment styles.
Paedophiles linked with pre-occupied/fearful attachments.
What personalities might someone have if they formed dismissive avoidant attachment styles?
Avoids closeness and emotional connections. Distant, critical, rigid and intolerant.
What did Jeffrey (1965) say about crime and learnt behaviour?
Criminal behaviour develops through operant conditioning. Behaviour has been enforced in the past, or aversive consequences/punishments do not control or prevent future occurrences.
Why might criminal behaviour not be reduced through operant conditioning?
Jeffrey (1965) and Skinner would say that any aversive consequences/punishments for behaviour need to be immediate to have the best effects. With court proceedings and police investigations, it can often be months before any official punishment is received.
What is olfactory aversive conditioning in the reduction of paedophilic behaviour?
Pairing of unpleasant smells with pictures of children (or any behaviour/stimulus you want to reduce) in order to decrease attraction to them.
What is masturbatory re-conditioning in the reduction of paedophilic behaviour?
Conditioned to masturbate to pictures of adult women, rather than children.
What did Marshall (2006) study and what was found?
The reconditioning of sex offenders. Olfactory or masturbatory conditioning on Bill. Treatments worked and he went on to have romantic relationships with women.
