BANDURA - SLT

what is the aim of bandura 1961

see whether aggressive behaviour could be acquired through observing and imitating an aggressive model and whether this is more likely with a same sex model

what is the procedure of bandura 1961

lab study 36 males and 36 females aged 3-6 years from the stanford uni nursery

matched pairs

placed in groups of 3 and randomly allocated one of these conditions…

1. aggression group- observed an adult kicking and shouting at bobo doll

2. non aggression group- observed an adult assembling toys

3. control group - children played alone

step1- in room playing

step2- deliberately frsutrated by being told the toys werent for them

step3- observed through one way mirror with the bobo doll

what were results from bandura 1961

children in aggression group more likely to imitate aggression than non aggression group

more likely in boys although not with verbal aggresssion

What were conclusions of bandura 1961

aggression can be acquired by observing and imitating an aggressive model.

its more likely boys to imitate a same sex model with physical aggression

what was the aim of bandura 1963

see whether filmed aggression can affect child’s aggressive behaviour as much as a live model

see whether a cartoon had the same effect

what was the procedure of bandura 1963

lab study with 48 males and 48 females from stanford uni nursery aged 3-6 yrs

randomly allocated to one of 4 conditions…

1. live aggression condition- children observed adult aggressing towards bobo doll

2. filmed realistic aggression- children watched adult aggress towards doll on screen

3. cartoon aggression condition- black cartoon cat aggressed towards bobo doll on screen

4. control- played with no model

step1- played no

step2- deliberately frustrated

step3- observed through one way mirror with doll

what were the results of bandura 1963

mean number of aggressive acts..

1. live=83

2. filmed=92

3. cartoon=99

4. control=54 significantly lower than observing groups

what were the conclusions of bandura 1963

exposure to live or filmed/ on screen aggression increases a child aggressive behaviour even if modelled by a cartoon

evaluate bandura (all studies)

+apply to social workers to better understand and intervene with children living with an aggressive parent/model to reduce imitated aggression in the future

-lab lacks ecological validity

+standardised controls such as using similar temperament kids from stanford uni nursery

-unethical to induce frustration and expose them to aggression

+generalisable as equal male and female ppts so representative of population

what was the aim of bandura 1965

to see if reinforcement and punishment of an aggressive model would influence the aggressive behaviour displayed by the observing children in response to frustration

what was the procedure bandura 1965

lab study with 33 girls and 33 boys aged 3-5 yrs from stanford uni nursery

all allocated to one of three conditions…

1. model-rewarded condition- 2nd adult seen to reward aggressive model by giving them chocolate

2. model-punished condition- 2nd adult seen to cold and slap aggressive model

3. no consequence condition- model neither rewarded nor punished for their behaviour

step1- play in room

step2- deliberately frustrated

step3- observed through one way mirror with bobo doll

what were the results of bandura 1965

model punished condition group much less aggressive and those in the model rewarded group were much more aggressive

however introducing the reward much more obviously increased aggression

what were the conclusions of bandura 1965

vicarious punishment reduces imitated aggression

however promise of reinforcement more more powerful influence on aggression
