Title: Evolutionary Theory
1Evolutionary 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
2Evolutionary 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
7Psychology 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?
8Psychoanalytic Theory
- ? Sigmund Freud
- ? 18561939
- ? Psychic Determinism
- A CIGAR IS NEVER JUST A CIGAR
9Freudian 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
10Defense Mechanisms
- ? Used to reduce anxiety
- REPRESSION
- RATIONALIZATION
- DENIAL
- PROJECTION
11Freudian 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 -
12Policy 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
13Principles of Learning
- ? Three types of learning
- ? Classical conditioning
- ? Operant conditioning
- ? Observational (vicarious) learning
14Classical Conditioning
15Principles 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
16Principles 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).
17MOLECULAR 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
18Principles of Learning
GERALD PATTERSON AND FRIENDS
19Observational 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.
20Media 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
21Policy Implications of Behaviorism
- ? Criminals can learn pro-social behaviors to
replace criminal actions. - ? Classical Conditioning ? Aversion therapy
- ? Operant Conditioning ?Token economy
22Cognitive 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)
23Cognitive 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
24Kohlbergs 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.
25Kohlbergs 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.
26Cognitive 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
- ?
27Policy 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
28Theory 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)
29Personality 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

36HARE 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)
37Policy 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?
38Intelligence and Crime
- ? Feeblemindedness was once thought to be a
cause of crime. - ? What exactly is IQ and how does it relate to
criminal behavior?
39A 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
40IQ 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
41IQ and Crime
- ? Travis Hirschi and Michael Hindelang
- ? The Bell Curve
- ?Direct effect
- ? Most criminologists find evidence of indirect
effects - IQ ? School, Peers, etc. ? Crime
42Conclusion
- ? 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.
