The Psych of Criminal Behaviour Flashcards
(107 cards)
Why is crime a concern for Canadians?
Public confidence in corrections is low
Media portrays crime inaccurately, emphasizing sensational cases
Crime has significant social and economic impacts
Need for evidence-based approaches to reduce reoffending
Why is public confidence in corrections low and how can it be improved?
Perceived ineffectiveness in reducing recidivism
Failure to address criminogenic needs (e.g., antisocial attitudes, peers)
Media could help by portraying accurate crime data and successful rehabilitation
Public awareness of effective interventions could increase trust
What are the characteristics of a typical offender?
Poor self-regulation
Substance abuse problems
Antisocial peer relationships
Problematic family background
What is the interdisciplinary approach to understanding criminal behaviour?
Combines psychology, criminology, and sociology
Cognitive social learning theory explains behavior via internal and external factors
Meta-analyses help identify effective interventions based on key risk factors
How is public perception of criminal justice shaped?
Media often emphasizes extreme cases
Public believes corrections are ineffective
Media and education should highlight ordinary crimes and successful treatments
What are the current crime trends in Canada?
Majority of crimes are non-violent and committed by ordinary individuals
Influenced by socioeconomic and mental health factors
Effective interventions focus on addressing criminogenic needs
What are the financial and social impacts of crime in Canada?
High cost to justice system, healthcare, and victim services
Harm to individuals and communities
Targeted interventions reduce reoffending and associated costs
What are the key biological factors linked to criminality?
Genetics (e.g., MAOA gene)
Neurochemistry (e.g., serotonin, dopamine)
Hormones (e.g., testosterone)
Psychophysiology (e.g., heart rate, skin conductance)
Interactions among subsystems
What does Life History Theory suggest about antisocial behavior?
Harsh/unpredictable environments → riskier strategies
Risky behavior may increase reproductive success
Lower parental investment, more impulsivity
Explains variability across individuals/societies
What are the challenges of applying Life History Theory?
Difficult to isolate all environmental factors
Complex interactions hard to measure
More longitudinal and experimental studies needed
Why do people view biological explanations of crime as deterministic?
Genes seen as unchangeable
Evolution linked to “hardwired” traits
Less belief in rehabilitation
How can we reduce deterministic thinking about biological theories?
Emphasize gene–environment interaction
Show compatibility with social/environmental interventions
Integrate biological and traditional theories
Why might females have greater resilience to aggression via MAOA?
MAOA is X-linked
Females have two X chromosomes
One functional copy can compensate for the other
Biological buffer against aggression/crime
What are the basic principles of evolutionary psychology?
Behaviors are adaptations to ancestral problems
Evolved psychological mechanisms guide behavior
Focus on survival, mating, status, resource acquisition
How does evolutionary psychology explain crime?
Crime may be adaptive in certain ancestral contexts
Aggression/theft helped secure mates or resources
Male-male competition, dominance strategies
How do biology and environment interact in shaping criminality?
Environment shapes gene expression (e.g., prenatal exposure)
Adaptive phenotypic plasticity (response to current conditions)
Biology sets potential, environment shapes outcome
How are biological and evolutionary theories compatible with traditional theories?
Evolution explains why, traditional theories explain how
Complementary perspectives (e.g., biology + social learning)
Broader understanding when combined
Not mutually exclusive
What do psychodynamic theories emphasize as causes of crime?
Inability of internal psychic forces to control antisocial impulses
Internal psychic forces include the id, ego, and superego, which develop through stages.
What are the two popular control theories in psychodynamic theories of crime?
- Hirschi’s social control theory
- Gottfredson and Hirschi’s general theory of crime
What does Hirschi’s social control theory suggest about crime?
People don’t commit crime because of bonds with society, including attachments, commitment, involvement, and belief in rules.
What is Gottfredson and Hirschi’s general theory of crime based on?
The degree of self-control gained from effective parenting practices.
Define classical conditioning.
Learning that occurs when an unconditioned stimulus is paired with a neutral stimulus, producing a conditioned response.
Define operant conditioning.
Learning that occurs by experiencing environmental consequences caused by behavior, such as reinforcement and punishment.
What does Sutherland’s differential association theory emphasize?
Criminal behavior is learned through interactions with others, especially with antisocial attitudes.
