CRIM1000: Aggression and Developmental Theories
• Why is aggression important?
➢ Childhood aggression = strongest predictor of persistent anti-social behaviour over
life course.
• Aggressive-behavioural continuity (preventing incarceration)
➢ Home-based toddler sibling aggression. Can easily lead to participation in bullying in
early adolescence —> graffiti —> smoking (early adulthood).
➢ Different developmental stages
➢ Outcome we want to prevent: adult criminal behaviour, which leads to
incarceration.
• Definition: aggression
➢ Developmental stage: antisocial behaviour during childhood (2-11yrs).
➢ Harmful intentional behaviour
➢ Committed during aroused state
➢ Pereied as aersie y iti defiitio: Braie, 94.
➢ Encompasses: oppositional behaviour; noncompliance.
• Categories: proactive versus reactive
➢ Proactive: instrumental
➢ Reactive: hostile (in response to provocation).
➢ Overt vs covert
➢ Overt is direct physical/verbal aggression
➢ Coert is ore ofte see i girls. It is ore sutle. It is relatioal or soial
aggression.
➢ Behaviour co-occurrence: people can participate in more than one category.
• Hostile Attribution Bias
➢ Involves cognitive distortion
➢ Defied: tedey i aggressie kids to iterpret others ehaiours as aggressie,
ee if theyre eutral
• Early starters vs late starters
➢ Early starter pathway
❖ Kids display early signs of aggression. Higher risk of crime persistence.
❖ Exposed to coercive/ineffective parenting strategies at home
❖ At school, typically neglected by teachers and peers, leading to aggressive
kids gravitating to deviant peer group.
❖ Aggression escalates.
➢ Late starter pathway
❖ Delinquency peaks around adolescence
❖ Age out of it
• Origins of physical aggression (Tremblay)
➢ Innate, must be unlearned for kids to be properly socialised
➢ Emphasises importance of early intervention.
➢ Emphasises role of impulsivity/hyperactivity.
