7. Bandura et al. (1961) - Learning Approach - done Flashcards
Aim of Bandura (2)
To investigate whether a child will learn aggression by observing a model and if the sex of the model would matter
4 hypothesis of Bandura
- observed aggression will be imitated
- observed non-aggression will be imitated
- children is more likely to copy same sex model
- boys will be more likely to copy aggresion than girls
Meaning of imitative learning - Bandura et al (1)
learning new behavior through observing role model and imitating it later in the absence of the model
Research method and design of Bandura
Lab experiments and independent measures design
IV of Bandura (3)
- model type (aggressive and non)
- sex of the model (same or not)
- learner gender
DV of Bandura
behavior of the child
Sample of Bandura (5)
total: 72 children aged 3-6 years old
36 of each gender
from Stanford university nursery
opportunity sampling
What did they do before the experiment of Bandura (5)
the children were watched by an experimenter and teacher who knew them and rated on a 4 point scale on their aggression
then assigned into 3 groups with aggression matched
then some children were checked again and got similar results by other observers for inter rater reliability
annoyed the children deliberately - child was informed their ‘favorite toy’ was reserved for someone else after 2 minutes of playing
distribution of sample in Bandura (3)
12 girls and 12 boys were in control groups
24 each with aggressive and non aggressive
then 12 with different sex models - 6 boys and 6 girls
Procdure of Bandura (5)
Control - did not see any model –> just played
In the room there were Bobo doll, mallet, tinkertoy set
non aggressive - assembled the tinkertoy set for 10 minutes
aggressive - assembled the toy for a minute and then attacked the Bobo doll for 9 minutes. Verbal aggression was used as well: kick him
observed for 20 minutes through one way mirror
behavior was observed in 5 second intervals
Results of Bandura (5)
children exposed to aggressive behavior - imitated.
imitation was greater in boys than girls
boys - physical aggression
girls - verbal aggression
imitative aggression from boys - 25.8
imitative aggression from girls - 7.2
less imitative if it was different gender
conclusions of Bandura (3)
children are more likely follow same sex
boys are more likely imitate aggression more than girls
observed aggression is imitated
Strengths of Bandura (3)
+ Lab - control extreanous variables
–> they saw the model for the same exact time, model behavour was standardised- reliable and replicable
+ high inter rater reliablilty - 2 people were observing
+children were unaware they were being watched - increased validity –> less likely to show demand characteristics
Weakness of Bandura (3)
- only 6 children used in each condition (except control) –> small sample - hard to generalise, as well as they were all from teh Stanford university nursery - hard to generalise
- the reason the children acted may have been to demand characteristics - they may have thought the model wanted them to be aggressive
- no study done afterward to see if the aggressin stuck?
Ethics regarding Bandura (2)
- they were annoyed - physchologicaly distressing
- no consent or right to withdraw to the children - they may be physchologically distressed
