L18 - Aggression and Antisocial Behaviour Flashcards
Define aggression:
Intentional behaviour aimed at hurting others
What is instrumental aggression?
Aimed at achieving a goal - physical aggression
What is relational aggression?
Aimed at harming others’ interpersonal relationships
What is Antisocial behaviour?
Behaviour which violates rules or conventions of society
What are conduct problems?
Generic term to cover these types of behaviour
Are antisocial and prosocial behaviours direct opposites?
- Traditionally thought of as opposite poles of the same thing
- Correlated but distinct: diff developmental patterns and predictors and outcomes
What was a study looking at early aggression?
- Sharing tasks had the highest outcome in 18mo, but some aggression was seen in tugging/bodily force (low frequency)
- No gender differences at 18mo
What were the patterns of aggression with age?
- Aggressive behaviour starts early, seen at 18mo
- 18mo - 3yo = increase in physical aggression
- 3yo - childhood = physical aggression decreases
- Relational aggression increases from toddlerhood to childhood
- Antisocial behaviour increases into adolescence, peaking at 17-18yo
What is the continuity of aggressive behaviours? (Physical aggression)
- Physical aggression seen in most typically developing toddlers
- Small group of children continue to show physically aggressive behaviour throughout childhood
- Rates of aggression in childhood predict later antisocial behaviour
What was Moffit’s theory?
- People strat early on to have aggressive behaviours, and then have these behaviours for the rest of their lifetime (life course persistent)
- OR normative behaviour (adolescence limited)
What are gender differences in aggression?
- Males more likely to be aggressive than females
- Difference develops from toddlerhood, increases into childhood and adolescence
- Direct (instrumental) vs indirect (relationality) aggression
What are the importance of genetic factors?
- 40% of risk factors for aggression is due to genetics
- Seen within adoption studies - compare adopted parents (env) from bio parents and check their child’s criminality
- Found that when env is criminal and bio is fine = criminality = 7%
- But when bio and not env = 12%
- Both bio and env = 40% criminality
What are early and prenatal risk factors?
- Maternal age: younger parents = child aggression
- Parental antisocial behaviour
- Maternal Stress: Associations between maternal stress during pregnancy and child aggression, Plausible bio pathways and post-natal stress
What was a study looking at prenatal depression and antisocial behaviour?
Depressed mothers in pregnancy are more likely to be violent teenagers
What are individual factors?
- Temperament: Difficult temperament in infancy = later aggression/delinquency
- Aggressive behaviour in young children can also elicit poorer interactions and additional risk factor
