Bandura et al. Flashcards
What were the 4 hypothesise?
- Observed aggressive behaviour will be imitated, so children seeing aggressive models will be more aggressive than those seeing non-aggressive models
- Children seeing non-aggressive models will be LESS aggressive than those with no model
- Children are more likely to copy same-sex model
- boys will be more likely to copy aggressive behaviour than girls
What is the aim of Bandura et al?
To investigate whether children would learn aggression through observation of an aggressive model, and would reproduce this behaviour in the absence of the model, and whether the sex of the model played an importance.
Which of the learning approach assumptions does Bandura et al. come under?
Social learning Imitative learning: The learning of a new behaviour which is observed in a role model and imitated later in the absence of the model.
What experimental design was used in Bandura et al?
Matched threes - held in a pilot observation prior to beginning the experiment, to match children’s natural aggression so that they could be evenly distributed between levels of the IV
Inter-rater reliablity = 0.89
rated on extend to which Pp displayed:
- physical aggression
- Verbal aggression*
- aggression towards innatimate objects*
- aggression inhibition*
What were the IV’s in Bandura et al?
model type: Aggressive model; non-aggressive model
model gender: same gender as child (F or M); opposite gender as child (F or M)
Learner gender: Boy; girl
What was the DV in Bandura et al?
The aggression of each child, measured through controlled observation in room 3.
How many children were in the sample of Bandura et al?
72
36 F; 36 M
What sampling technique was used in Bandura et al?
Opportunity Sampling - Nursery attached to Stanford University
What age range were the children in Bandura et al?
37 - 69 months
Pre-test procedure
Natural observation in Pp’s nursey by the experimenter and a teacher who knew them well
rated on 4 5-point scales (0-4) on:
- Physical aggression
- Verbal aggression
- aggression towards inanimate objects
- aggression inhibition (anxiety)
How were Pp allocated equally to each level of IV?
- 12 boys and 12 girls assigned to control groups - no model
- 6 Pp of each gender were then separated into aggressive same sex model, aggressive non-same-sex model, non-aggressive same-sex model, and non-aggressive non-same-sex model.
What happened in room 1 in Bandura et al?
Both experimenter and child (1 at a time) entered the room. The child was shown to a corner of the room with a variety of toys.
The Model (aggressive or non-aggressive, or no model) was then shown to the opposite corner of the room with separate toys to play with
lasted for around 10 minutes
What toys were in room 1 or Bandura et al?
Child: small table, stickers, potato prints
Model: 5ft bobo doll, mallet, tinker toy set, small table & chair
Aggressive procedure in room 1
Model assembled tinker toys for about a minute, before commencing aggressive behaviour towards bobo doll.
eg.
- sitting on bobo doll
- hitting bobo doll with mullet
- tossing doll up and kicking it
- punched doll’s nose
- verbal aggressive: “kick him!” “pow”
- Verbal non-aggressive: “he sure is a tough fella”
What happened in room 2 in Bandura et al?
Each child, one at a time was bought into another room, where they were introduced to some “relatively attractive toys” for the child to engage in.
After approx. 2 minutes of the child being engaged, the experimenter tells the child these toys are actually not for them, and are being saved for others.
