Developmental Area Flashcards
What were banduras hypotheses
- children exposed to aggressive model would reproduce aggressive acts resembling those of the models
- observing non-aggressive adults would inhibit children’s behaviour and they would display less aggression than control groups who did not witness any model
- children would imitate behaviour from same sex models more than opposite sex models
- boys would show more aggression than girls, particularly in male aggression role model condition
What was banduras sample
72 children enrolled at Stanford University (even girls and boys)
Aged 37 to 69 months
What was the experimental design bandura
Matched groups
Matched on mean age, gender split, mean aggression rating, plus a control group
How was mean aggression rating of children in banduras obtained
2 observers, watched children in social interactions at nursery Rated on 5 point scales -physical aggression -verbal aggression -aggression towards inanimate objects
Checked for inter rated reliability, 51 scores correlated
-aggression inhibition
What was stage one of banduras study
-individually taken to room, shown high interest toys: potato printing and stickers
-model sat with bobo doll & mallet
-child told those were models toys only
Non aggressive model - ignored bobo
Aggressive model - player with tinker for 1 min, then bobo doll
How long were the children in each stage for in banduras
1-10mins
2-2mins
3-20mins
What happened in stage two of banduras
-arousal
Child taken into small room with lots of attractive toys: fire engine, train, spinning top
Told he/she could play, but once they settled told they were the very best toys saved for the other children but there was other toys in other room
What was stage 3 of banduras
Toys (same as first room ) set up in same place for each child
Aggressive toys-bobo, mallet, dart guns
Non aggressive toys-crayons, farm animals
20min child allowed to play while being observed through one way mirror , every 5 seconds note made of behaviour shown
Some results of banduras study
Imitation of physical aggression with aggressive model-girls-7.2, boys-25.8
Imitation of physical aggression non aggression model-girls-0, boys-1.5
Verbal aggression aggressive model- girls-2.0, boys-12.7
Were any hypothesis of banduras supported
- Reproduce aggression - supported by sig diff between means of 36.7 (boys) compared to 26.1
- Boys more aggression than girls - partially supported, physical aggression boys mean 38.2 girls 12.7
- Influence of sex of model - small group sizes didn’t allow sig diff
What is conclusions of banduras study
Observing behaviour would produce imitative behaviour which would not be expected if that behaviour had not been observed, moves on from skinners idea that behaviour is only shown if rewarded
Discuss ethics of banduras
- children themselves didn’t consent, and weren’t aware of right to withdraw
- teachers give consent in place of parents
- hard to debrief young children wouldn’t understand “don’t be aggressive”
- second arousal stage may be harmful causing anxiety in
- did consequences out weigh benefits brought by the study
Discuss validity of banduras
Controlled so little effect of extraneous variables
Toys in same place so not affected by first toy seen by child
Pre testing for aggression and matching eliminates participant variables
Discuss reliability of banduras
Highly replicable, as it was replicated 72 times
Sample not large enough to establish reliable effects as only 6 children in each condition
Discuss Population validity of banduras
Limited representativeness, may never have seen bobo doll and so just copied as didn’t know what else to do
Restricted sample, all parents may have similar characteristics such as socio economic status therefore children limited in representation of others
Only of children, are adults likely to imitate?
Discuss ethnocentrism of banduras
Only in America, different laws with gun ownership, affect likelihood of learning aggressive behaviour
If cultural norms always influence a child then study isn’t ethnocentric
How does bandura link to nature/nurture
Nature-boys more aggressive due to testosterone
Nurture-encouraging boys to play with trucks and guns not dolls
Nurture-environment influences behaviour
How does bandura link to freewill/determinism
Freewill-Physical aggression imitation of female model lower than male model, some choices by children as to what was acceptable way to behave
Determinism-testosterone predetermining normal levels of aggression in males, so more likely to display aggression
Why is bandura useful
- 1970s watershed, after 9pm classed as adult tv, as society accepted that tv can influence behaviour
- social learning theory used in society to impression behaviour or discourage it
Why does bandura fall into developmental area
Investigating how the environment around a child can influence the behaviour they end up adopting themselves
Why does bandura relate to behaviourst perspective
Believed that all behaviour is learnt, and developed SLT as an alternative to operant and classical conditioning
Why does bandura link to cognitive
SLT has cognitive processes
Attention-have to notice behaviour
Memory-retaining behaviour seen in order to reproduce
How does bandura link to key theme external influences
Demonstrates importance of environment in which child is brought up as the external factors will shape a persons behaviour
What was aim of Chaney
See if rewards could be used to increase health behaviours and if principle of reinforcement could be applied to health setting
What was chaneys procedure
- parents with children using normal inhaler recruited through gp
- parents contacted by phone, then visited at home
- given questionnaire about current inhaler and consent form
- given funhaler for 2 weeks
- at end of two weeks, revisited and given another questionnaire to complete
What did the funhaler look like
Inhaler with whistle and spinning disk, when child exhale the disk spin and whistle sound appears, long steady breath meant the best toy performance
What was chaney sample
32 Australian children, 22 boy, 10 girl
1.5 and 6 years old
Average duration of asthma for 2.2 years
