Title: Evolutionary Theory


1
Evolutionary Theory
  • ? Uses principles of evolution to explain modern
    human behavior
  • ? Rape
  • ? Cads and dads theory
  • ? Criticism
  • ? Difficult if not impossible to test
  • ? Evidence sometimes runs counter to predictions

2
Evolutionary Theory (2 of 2)
  • ? Rape
  • ? Evolutionary processes allow males who are
    pushy and aggressive in the pursuit of sex to
    pass on their genes successfully.
  • ? Cads and dads theory
  • ? Alternative strategies for reproductive success
  • ? Cadspretend caregivers who really want to
    reproduce with as many females as possible
  • ? Dadsinvest time and energy to help nurture and
    raise offspring

3
Summary
  • ? Many biological factors appear to be related to
    criminal behavior
  • ? Inherited?
  • ? Results of biological harms?
  • ? Biological factors contribute to criminality in
    certain environmental circumstances.

4
Biological Theories Criticisms
  • ? Ignores some types of crimes
  • ? White-collar
  • ? Organized
  • ? Political crime
  • ? Focuses on aggression or antisocial behavior in
    children and street crime in adults

5
Policy Implications (1 of 2)
  • ? Still fear of ethical problems
  • ? Biology not necessarily destiny
  • ? Provide unsound justifications for the control
    of minority populations
  • ? New eugenics
  • ? Gene therapy
  • ? Discrimination based on presence of biological
    risk indicators

6
Policy Implications (2 of 2)
  • ? The upside? Criminality as a public health
    problem
  • ? Prenatal care for at-risk mothers
  • ? Strengthen environmental counterbalances for
    children with biological risk indicators

7
Psychology and Crime
  • ? How does a psychologist or psychiatrist develop
    and understand the criminal mind?
  • ? What does psychology contribute to the study of
    the criminal mind?
  • ? What is the psychological approach to the study
    of crime?

8
Psychoanalytic Theory
  • ? Sigmund Freud
  • ? 18561939
  • ? Psychic Determinism
  • A CIGAR IS NEVER JUST A CIGAR

9
Freudian Elements of Personality
  • ? Conscious vs. Unconscious Mind
  • ? Id If it feels good, do it!
  • ? Superego conscienceStealing is wrong.
  • ? Ego psychological thermostat that regulates
    the wishes of the id with the social restrictions
    of the superego

10
Defense Mechanisms
  • ? Used to reduce anxiety
  • REPRESSION
  • RATIONALIZATION
  • DENIAL
  • PROJECTION

11
Freudian Explanations of Delinquency
  • ? Overactive Id
  • ? Delinquent Superego
  • ? Delinquent Ego
  • Crimes with special meaning
  • Translating psychoanalysis into rehabilitation?
  • Works for articulate adult neurotics who can talk
    out their problems

12
Policy Implications of Freudian Theory
  • ? Drawbacks
  • ? Almost impossible to test empirically (Cannot
    be directly observed and measured)
  • ? Still maintains a place in psychology of
    criminal behavior
  • Many concepts from Freud used in modern theory
  • LOW SELF CONTROL
  • PRO-CRIMINAL ATTITUDES

13
Principles of Learning
  • ? Three types of learning
  • ? Classical conditioning
  • ? Operant conditioning
  • ? Observational (vicarious) learning

14
Classical Conditioning
15
Principles of Learning
  • ? Positive reinforcement increases the target
    behavior by rewarding the individual
  • ? Negative reinforcement increases the target
    behavior by removing an unpleasant stimulus
  • ? Punishment reduces the odds of the target
    behavior being repeated

16
Principles of Learning
  • ? Delinquency tied to parents failure to
    effectively condition their children away from
    bad behavior
  • Inconsistent and harsh punishment (Glueck and
    Glueck).
  • ? Effective parenting (monitoring, punishing, and
    reinforcing behavior)?nondeliquent children
    (Patterson).
  • ? Parental behaviors may have few effects on the
    childs long-term development (Harris).

17
MOLECULAR GENITICS and PARENTING
  • Study Kids can carry genes magnifying parent's
    influence
  • The almost-famous 5-HTTLPR serotonin
    transporter-promoter gene, which governs the
    activity of the mood chemical serotonin in the
    brain and essentially comes in three varieties.
    About 1 in 5 children are born with a variant
    that, according to studies, makes them highly
    sensitive to the effects of neglectful,
    insensitive or abusive parents

18
Principles of Learning
GERALD PATTERSON AND FRIENDS
19
Observational Learning
  • ? Albert Bandura (Bobo doll experiments) most
    human learning is not based on trial and error
    (operant conditioning).
  • ? Effects on criminal behaviors are difficult to
    determine.

20
Media and Crime
  • ? Does media (TV and movies) influence
    aggression, violence, and criminal behavior?
  • ? Conducive to role modeling
  • ? Perpetrators not punished
  • ? Targets of violence show little pain
  • ? Few long-term negative consequences
  • Some evidence (but still debate)reducing
    exposure may reduce aggression

21
Policy Implications of Behaviorism
  • ? Criminals can learn pro-social behaviors to
    replace criminal actions.
  • ? Classical Conditioning ? Aversion therapy
  • ? Operant Conditioning ?Token economy

22
Cognitive Psychology
  • ? Humans ability to engage in complex thoughts
    influences behavior.
  • ? Cognitions (like behaviors) can be learned.
  • ? Focus on
  • ? Cognitive structure (how people think)
  • ? Cognitive content (what people think)

23
Cognitive Structure
  • ? Kohlberg's theory of moral reasoning humans
    advance through predictable stages of moral
    reasoning
  • ? Self-control
  • ? Ability to empathize
  • ? Ability to anticipate consequences
  • ? Ability to control anger

24
Kohlbergs Stages of Moral Development (1 of 2)
  • ? Stage 1
  • ? Right is blindly obeying those with power and
    authority.
  • ? Emphasis is on avoiding punishment.
  • ? Interests of others are not considered.
  • ? Stage 2
  • ? Right is furthering ones own interests.
  • ? Interests of others are important only as a way
    to satisfy self-interests.
  • ? Stage 3
  • ? Moral reasoning is motivated by loyalties to
    others and a desire to live up to others
    standards.

25
Kohlbergs Stages of Moral Development (2 of 2)
  • ? Stage 4
  • ? Right is following the rules of society and
    maintaining important social institutions (e.g.,
    family, community).
  • ? Stage 5
  • ? Moral decisions are made by weighing individual
    rights against legal principles and the common
    good.
  • ? Stage 6
  • ? Moral decisions are based on universal
    principles (e.g., human dignity, desire for
    justice).
  • ? Principles are considered across different
    contexts and are independent of the law.

26
Cognitive Content
  • ? Rationalizations or denials that support
    criminal behavior
  • ? For example, a criminal thinks, Im not really
    hurting anyone.
  • Extremely common for sex offenders
  • ? Criminals are more likely to express such
    thoughts
  • Sociologists are often skeptical (time-ordering)
  • Psychologists NEGATIVE REINFORCEMENT
  • ?

27
Policy Implications of Cognitive Psychology
  • ? Cognitive theory translates easily into
    practice.
  • Cognitive skills programs teach offenders
    cognitive skills like moral reasoning, anger
    management, or self-control.
  • Cognitive restructuring attempts to change the
    content of an individuals thoughts.
  • ? Combination cognitive-behavioral have track
    record of success

28
Theory in Action
  • ? Multisystematic therapy (MST)
  • ? Creator Scott Henggeler and associates
  • ? Reduces criminal behavior
  • ? Comprehensive approach
  • ? Targets many areas for change
  • ? Uses many different techniques (not just
    cognitive-behavioral programs)

29
Personality and Crime
  • ? Crime and delinquency related to the presence
    of some personality trait
  • ? Personality trait a characteristic of an
    individual that is stable over time and across
    different social circumstances
  • ? Personality the sum of personality traits that
    define a person

30
Personality Traits and Crime (1 of 3)
  • ? A number of related traits combine to form
    super factors
  • ? Several different models
  • ? Five-factor model
  • ? Tellegens personality model
  • ? Recent studies use the Multidimensional
    Personality Questionnaire (MPQ)

31
Personality Traits and Crime (2 of 3)
  • ? Personality dimensions in the MPQ
  • ? Constraint
  • ? Traditionalism
  • ? Harm avoidance
  • ? Control
  • ? Negative emotionality
  • ? Aggression

  • ? Social potency
  • ? Well-being
  • ? Social closeness

33
Criminal PersonalityThe Psychopath
  • ? A distinct criminal personality
  • ? One of the oldest concepts in criminology
  • MORAL INSANITY

34
Antisocial Personality Disorder (APD) from
DSM-IV
  • 1. Disregard for the rights of others. At least
    three of the following
  • behaves in a way that is grounds for arrest,
    deceitful and manipulative, impulsive,
    aggressive, irresponsible, lack of remorse
  • 2. Age 18 or older
  • 3. A history of child conduct disorder
  • 4. Antisocial behavior not a product of
    schizophrenic episode

35
Psychopath is narrower concept
  • Hervey Cleckleys (1957) The Mask of Sanity
  • Key features Manipulative, Superficial charm,
    Above-average intelligence, Absence of psychotic
    symptoms, Absence of anxiety, Lack of remorse,
    Failure to learn from experience, Egocentric,
    Lack of emotional depth
  • Other Characteristics Trivial Sex life,
    Unreliable, Failure to follow a life plan,
    Untruthful, Suicide attempts rarely genuine,
    Impulsive, Antisocial behavior

36
HARE PCL
  • The Psychopathy Checklist
  • Interview
  • Measures different aspects of psychopathy (each
    scored on a 0-2 scale)
  • Has produced very interesting studies (difference
    between psychopath and non-psychopath inmates)

37
Policy Implications of Personality Theory
  • ? Personality traits consistently predict
    delinquency and crime.
  • ? Criticisms
  • Personality traits are often portrayed as
    impossible to change (See, Psychopathy)
  • What causes personality traits?

38
Intelligence and Crime
  • ? Feeblemindedness was once thought to be a
    cause of crime.
  • ? What exactly is IQ and how does it relate to
    criminal behavior?

39
A Brief History of Intelligence Testing
  • ? Binet started out like his peers Measuring
    peoples skull size
  • Not much differenceworried about bias in the
    tests
  • Developed a hodgepodge of tests measure
    identify learning disabled children
  • Not meant to be a measuring device for
    intelligence in normal students
  • Translated to English, used to identify morons
    and low grade defectives as part of eugenics

40
IQ and Crime
  • ? There is an IQ gap of 810 points between
    criminals and noncriminals, even when
    statistically controlled for race and social
    class.
  • ? IQ is not a very strong indicator of criminal
    behavior.
  • But, it does consistently predict

41
IQ and Crime
  • ? Travis Hirschi and Michael Hindelang
  • ? The Bell Curve
  • ?Direct effect
  • ? Most criminologists find evidence of indirect
    effects
  • IQ ? School, Peers, etc. ? Crime

42
Conclusion
  • ? The common emphasis of all psychological
    theories is on the individual.
  • ? Modern Theory
  • LEARNING
  • COGNITION and IQ
  • PERSONALITY
  • ? Many psychological theories translate well into
    treatment programs.
