Ac 4.1 Criminological Theories Informing Policy Development Flashcards
Biological theories informing policy Development -
What is The theory for brain chemistry?
Crime is due to low levels of serotonin
↓
Criminals lack vitamins and minerals which alters brain chemistry
Biological theories informing policy Development -
What is The linked policy for brain chemistry?
Changing neurochemical levels By giving them vitamin and mineral supplements
Changed individuals diets to increase serotonin → given chocolate, oily fish and nuts
Biological theories informing policy Development -
What are The strengths of this policy?
Clear evidence of effect - 26% improvement
Researchers used A placebo so we know it isn’t just The ‘placebo effect’
Has other experiments to back up results
Easy to impliment in prisons
Biological theories informing policy Development -
What are The weaknesses of this policy?
Expensive For prisons to provide these types of foods
People in The real world eat what they like - difficult to impose once out of prison
Not 100% effective so must be only factor
Biological theories informing policy Development -
What is The theory For genetics?
Inheritance of genes could explain Human behavioural characteristics
Reinforces biological determinism - biology contributes to Social problems
Biological theories informing policy Development -
What is The linked policy genetics?
Eugenics
Steracisation of People with now-desirable traits
Criminals can’t have children in case of criminal offspring
Biological theories informing policy Development -
What are the strengths of this policy?
Can be used To protect People from themselves
Biological theories informing policy Development -
What are the weaknesses of this policy?
Can’t be morally justified
Assumes biological determinism
Twin studies prove its Not just genetic factors
Not justifiable because baby hasn’t been born let alone committed A crime
Not easy to apply
Can’t be used fairly
Complicated - how bad does crime need to be before implicated
Biological theories informing policy Development -
What is The theory For biological?
Born to be A criminal → biological determinism
Biological theories informing policy Development -
What is The linked policy For biological?
The death penalty
Biological theories informing policy Development -
What are The strengths of this policy?
Stops People being in prison fir long periods - may be cheaper
Morally some People justify A life For life ‘
70% of prisoners reoffend - safest For society to use death penalty on worst offenders
Biological theories informing policy Development -
What are The weaknesses of this policy?
USA murder rates are 25% higher in states that do have the death penalty than those that don’t
↓
Death penalty not a deterrent
Murder is often in The heat of The moment or because of drugs therefore People don’t consider consequences
↓
Not A deterrent
Morally Not justifiable to take A life
Other solutions can Help prisoners to G0 straight and avoid reoffending
Individualistic theories informing policy Development -
What is the theory for Social learning?
Operant conditioning
Operant conditioning is linked to reinforcement. Reinforcement - anything that strengthens A behaviour and increases The likelihood of it happening
Positive reinforcement -when behaviour leads to A consequence that is rewarding (getting sticker- adding pleasure)
Negative reinforcement - when behaviour leads to The removal of an unpleasant consequence ( turning off alarm removes unpleasant sound - removing displeasure)
↓
Both increase chances of behaviour
Punishment - unpleasant consequence, removal of something nice or adding something bad.
↓
Reduces Chance of behaviours
Individualistic theories informing policy Development -
What is The linked policy For Social learning theory?
Behaviour modification- token economy
Reward System where rewards are provided For positive behaviour
Token is given For desired action, which is later exchanged For A treat
Positive reinforcement
Treats- family visits, weekly spending allowance, Personal clothing, leisure activities
Individualistic theories informing policy Development -
What are The strengths of this policy?
Good use of positive reinforcement that helps control behaviour in prisons
