Title: FORENSIC PSYCHOLOGY
1FORENSIC PSYCHOLOGY
- Turning To Crime
- CRIMINAL COGNITIONS
2Is crime rational?
- RATIONAL CHOICE THEORY says offenders weigh up
pros cons before offending - A COST-BENEFIT ANALYSIS
- Factors monetary gain, excitement, respect vs
shame, loss of freedom, fear - Some people have more to lose than others
3Do offenders think rationally?
- YOCHELSON SAMENOW (1977)
- Long-running study into criminal thinking at St
Elizabeths Psychiatric Hospital, Washington DC - Original sample 255 offenders
- Different races, social class, backgrounds
- In depth interviews, psychodynamic
4Criminal thinking errors 1
- Offenders make thinking errors different from
normal people - ? their cost-benefit analyses comes to different
conclusions - 40 different types of error
- CRIMINAL THINKING PATTERNS
- High expectations (search for perfection),
fearful of others, habitual lying, need for
power/control
5Criminal thinking errors 2
- AUTOMATIC THINKING ERRORS
- Lack of empathy/trust, doesnt accept
blame/responsibility, secretive - CRIME-RELATED THINKING ERRORS
- Offenders fantasise about certain crimes but
dont imagine consequences - YSs techniques led to creation of
COGNITIVE-BEHAVIOURAL THERAPY (CBT)
6Psychopaths
- Hervey Cleckley (1941) The Mask of Sanity
- Impulsive, callous, insincere no remorse or
empathy with victims - PRIMARY PSYCHOPATHS ? no fear
- SECONDARY PSYCHOPATHS ? compelled to take risks,
unstable life plan
7Violence Inhibition Mechanism (VIM) 1
- When other people are in pain (DISTRESS CUES),
normal people experience ancxiety and withdraw
(the VIM) - Biological mechanism, strengthened by parents
- Blair et al (1997) used Hares Psychopathy
Checklist (PCL) to identify 18 psychopaths
non-psychopaths in prison
8Violence Inhibition Mechanism (VIM) 2
- All men were matched for ethnicity, IQ and crime
(murder or manslaughter) - 28 slides 5 with distress cues
- 5 with danger
- Stress measured through SKIN CONDUCTANCE RESPONSE
(SCR) - Psychopaths showed less response to distress cues
and no different response to threatening images
9How does thinking develop?
- At A/S you were introduced to JEAN PIAGET
- Researched COGNITIVE DEVELOPMENT in children
- Maybe MORAL THINKING develops too.
10PIAGET EGOCENTRISM
- Piaget suggests EGOCENTRISM is seeing things only
from your own view
- Young children are MORALLY EGOCENTRIC
- Difficulty thinking about other peoples
feelings, intentions - Need for hard, fast rules
11PIAGET AUTONOMY
- Older children are AUTONOMOUS thinkers
- They consider other peoples intentions and
feelings - Importance of FAIRNESS and RESPECT
- Piaget interviewed children playing marbles
- Older ones could develop new rules!
12PIAGETS MORAL STAGES
- (1) PRE-MORAL JUDGMENT
- No idea about morals or rules
- Birth ? 5 years
- (same as SENSORI-MOTOR stage)
- (2) MORAL REALISM
- Egocentric stage rules are fixed
- 5-9 years
- (same as PRE-OPERATIONAL and CONCRETE OPERATIONAL
stages)
13PIAGETS MORAL STAGES
- (3) MORAL RELATIVITY
- Own internal morality can criticise rules
- 7 years
- (same as CONCRETE and FORMAL OPERATIONAL stages)
- Piaget gave children DILEMMAS to consider
- A boy deliberately causes small damage vs a boy
accidentally causes big damage - Which deserved most punishment?
14PIAGETS MORAL STAGES
- Stage 2 focus on CONSEQUENCES
- Punish boy who caused big damage
- Stage 3 focus on INTENTIONS
- Punish boy who caused deliberate damage
- CRITICISMS
- Eco Validity marbles????? Irrelevant!
- Validity did young children understand?
- Ethnocentrism culture-specific to West
15Introducing KOHLBERG
- Laurence Kohlberg (1927-87)
- American psychologist Harvard professor
- In youth, helped Jews escape Nazis by smuggling
them in banana crates! - Inspired by Piagets theories
16The Druggists Dilemma (1958)
- A woman was near death from a special kind of
cancer. There was one drug that might save her
that a druggist in the same town had recently
discovered
- The drug was expensive to make, but the druggist
was charging ten times what the drug cost him to
produce - 2,000 for a small dose
17The Druggists Dilemma (1958)
- The sick woman's husband, Heinz, tried to borrow
the money, but could only get 1,000 - He asked the druggist to sell it cheaper or let
him pay later. But the druggist said, "No, I
discovered the drug and I'm going to make money
from it - So Heinz got desperate and broke into the man's
store to steal the drug for his wife. - Should Heinz have broken into the laboratory to
steal the drug for his wife? - Why or why not?
18The Moral Stages
- Answer not important what matters is REASONS
for answer - STAGE 1 (Obedience)
- Heinz should not steal the medicine because he
will consequently be put in prison which will
mean he is a bad person
- Heinz should steal the medicine because it is
only worth 200 and not how much the druggist
wanted for it Heinz had even offered to pay for
it and was not stealing anything else
19The Moral Stages
- STAGE 2 (self-interest)
- Heinz should steal the medicine because he will
be much happier if he saves his wife, even if he
will have to serve a prison sentence
- Heinz should not steal the medicine because
prison is an awful place, and he would probably
suffer in a jail cell more than his wife's death
20The Moral Stages
- STAGE 3 (conformity)
- Heinz should steal the medicine because his wife
expects it he wants to be a good husband
- Heinz should not steal the drug because stealing
is bad and he is not a criminal
21The Moral Stages
- STAGE 4 (law order)
- Heinz should not steal the medicine because the
law forbids stealing, making it illegal
- Heinz should steal the drug for his wife but
also take the punishment for the crime. Criminals
cannot just run around without regard for the
law
22The Moral Stages
- STAGE 5 (human rights)
- Heinz should steal the medicine because everyone
has a right to choose life, regardless of the law
- Heinz should not steal the medicine because the
scientist has a right to fair compensation. Even
if his wife is sick, it does not make his actions
right
23The Moral Stages
- STAGE 6 (universal ethics)
- Heinz should steal the medicine, because saving
a human life is a more fundamental value than the
property rights of another person - Heinz should not steal the medicine, because
others may need the medicine just as badly, and
their lives are equally significant
24Criticising Kohlberg
- This view of morality is too focussed on JUSTICE
- What about compassion?
- Kohlbergs student, CAROL GILLIGAN
- Too ANDROCENTRIC based on male attitudes
- Female morality based on relationships,
childbirth, dilemmas like abortion
25Link Between Morality Crime?
- A more fundamental question
- Some things are unethical but not illegal
- Eg adultery
- Others are illegal but not morally wrong
- Eg Cash-in hand work (tax dodging)
26Link Between Morality Crime?
- A vegetarian animal-lover?
- Level 6 rejects conventional morality
- Replaces with own views on value of human life
- Serial killers do this
- Most terrorists claim to have a superior moral
vision
27Do Criminals Think Differently
- In 1964 David Matza challenged the idea that
criminals think differently from normal people - Based on CONTROL THEORY
- We all have criminal thoughts tendencies a
dark side
- SUBTERRANEAN VALUES vs FORMAL VALUES
- Fun, freedom spontaneity
- Work, duty order
28Drift Theory
- Matza says we drift into and out of deviant
behaviour - Stealing sweets in childhood?
- Drug taking at college or at Glastonbury?
- Pinching biros from the office?
- Criminals differ only in time, place, frequency
29Drift Theory Mood of Fatalism
- So its normal to DRIFT into delinquency
- You feel small, helpless, pushed around
- MOOD OF FATALISM
- Typical in young adulthood
- Restore MOOD OF HUMANISM
- Assert yourself, get noticed, get respect.
Through crime?
30Drift Theory
- Matza interviewed young offenders
- Many respected law-abiding values
- They knew their own behaviour was wrong
- Matza argues they think like everyone else
- but they neutralise guilt
31Drift Theory Guilt Neutralisation
- Matza interviewed young offenders
- Many respected law-abiding values
- They knew their own behaviour was wrong
- Matza argues they think like everyone else
- but they neutralise guilt
32Drift Theory Guilt Neutralisation
- Denial of responsibility blame parents, school,
peers - Denial of injury nobody was hurt, only having
fun - Denial of wrongfulness the victim deserved it
- Condemn the rule enforcers police are corrupt,
teachers unjust - Appeal to higher loyalties break law to help
family or friends
33Drift Theory
- Matza argues that GUILT NEUTRALISATION shows they
have the SAME VALUES as law-abiding people - This has been criticised
- Takes offenders self-reports at face value
(naive) - Only accounts for delinquency
- What about career criminals?
- Strong link to LABELLING THEORY
