Unit 2 - Classic Developmental Core Studies Flashcards
How does ‘external influences on children’s behavior’ relate to the developmental area?
The idea that children learn from the environments that they are in reflects the assumptions made in the behaviorist perspective
Summarise the background of Bandura’s study
- Behaviorists believe all behaviors can be explained of learning from the environment
- Bandura developed the ‘social learning theory’ which claims the people can learn through observation of adult role models and subsequently imitate their behavior
What was the aim of Bandura’s study?
To see whether children will imitate aggressive behaviour when given the opportunity, even when they saw the behaviors in a different environment and the role model was no longer present
What were the four hypotheses of Bandura’s study?
- Subjects exposed to aggressive role models would reproduce the aggressive acts
- Observing non-aggressive role models would have an inhibiting effect on the subsequent behaviour
- Subjects will imitate the behaviour of a role model of the same sex to them
- Boys are more likely to imitate aggressive behaviour than girls are
Describe Bandura’s sample
72 children from Stanford Nursery school (36b 36g)
aged 37m - 96m and average was 57m
What sampling method did Bandura use?
Oppurtunity
How did Bandura pre-test for the study?
To control for aggression, children were individually assessed on their levels of aggressiveness. They were rated by the the nursery school teacher and the experimenter on 4 rating scales:
- Psychical aggression
- Verbal aggression
- Aggression towards objects
- Aggression inhibition
What were the results of the inter - rater reliability for Bandura’s study?
0.89 - suggests a high level of inter - rater reliability between two observers and consistency.
What was Bandura’s experimental design?
Matched Pairs Design - children out into triplets and then randomly assigned to aggressive model, non - aggressive model or no model (control)
What were the 3 IV’s of Bandura’s study?
- participanst gender
- model gender
- model behaviour
What were the 5 model conditions of Bandura’s study?
- Aggressive female
- Non - aggressive female
- Aggressive male
- Non - aggressive female
- Control
In Bandura’s study what was stage one of the procedure in the aggressive models condition?
- Child was taken individually into a room
- Child taken to a table which had toys like stickers and potato printing
- Model sat at a different table with a mallet and bobo doll and played with them for 1 minute
- Model turned to the bobo doll and punched it, sat on it, struck it with the mallet, tossed the doll up, kicked it about the room. Repeated three times
- Model also dispersed verbally aggressive behaviour like “Hit him down”, “Sock him in the nose”, “pow”
- Model dispersed two non - aggressive comments “he keeps coming back for more” and “he sure is a tough fella”
In Bandura’s study was was stage one of the procedure in the non - aggressive model condition?
- Child was taken individually into a room
- Child taken to a table which had toys like stickers and potato printing
- Model sat at a different table with a mallet and bobo doll
- Model played with the non - aggressive toys and ignored the bobo doll
In Bandura’s study what was stage one of the procedure in the control condition?
They had no prior exposure to the adult models
How long did stage one of Bandura’s procedure last?
10 minutes
What was stage two of the procedure in Bandura’s study?
- Child taken to another room by the experimenter
- Child could play freely with attractive toys like spinning top and trains
- Once settled the experimenter said that they were her best toys and no just anyone could play with them
Why was it necessary for the experimenter to upset the child in stage two of the procedure in Bandura’s study?
Research proves witnessing aggression reduced immediate aggression and you need to get the child aroused and angry to give all groups equal chance of showing aggression
How long did stage two of Bandura’s procedure last?
2 minutes
What was stage three of the procedure in Bandura’s study?
- Child taken to another room with new toys - some non - aggresive (tea set, crayons) and some aggressive (mallet, bobo doll, dart gun)
- Child unknowingly observed by experimenter doing ‘work’, researcher and model behind one way mirror
- Child observed for 20 minutes and behaviour recorded every 5 seconds (240 pieces of data)
- Experiment was double - blind
How long did stage three of Bandura’s procedure last?
20 minutes
How was inter - scorer agreement found in Bandura’s study?
Half the children had their behaviour observed in the third stage by a second observer. The results were compared for consistency and found to be good - indicating high reliability
What were the 3 observation categories in Bandura’s study?
- Imitative behaviour
- Partial imitative behaviour
- Non - imitative aggressive behaviour
What was in the imitative behaviour category in Bandura’s study?
- Imitation of physical aggression - striking bobo doll with mallet, sitting and punching doll, tossing doll
- Imitation of verbal aggression - “Hit him down”, “Pow”, “Strike him down”
- Imitation of non - aggressive verbal responses - “He keeps coming back for more” and “He sure is a tough fella”
What was in the partial imitative behaviour category in Bandura’s study?
- Physical aggression - strikes objects with mallet except the bobo doll, sits or lays bobo doll on side but not aggressive towards it
What was in the non - imitative aggressive behaviour in Bandura’s study?
- Punches bobo doll - strikes, slaps or pushing aggressively
- Non - imitative physical / verbal aggression - physically aggressive acts towards objects other than bobo doll, hostile remarks “cut him”, “stupid ball”, “horses fighting, biting”
- Aggressive play - shoots darts or imaginary fire and aim
In Bandura’s study, how was hypotheses one proven?
1. Subjects exposed to aggressive role models would reproduce the aggressive acts
The results for physical and verbal acts are much higher
ie. Girls with aggressive female - 5.5 and 13.7
Girls with non aggressive female - 2.5 and 0.3
Boys with aggressive male - 25.8 and 12.7
Boys with non aggressive male - 1.5 and 0
In Bandura’s study, how was hypotheses two proven?
2. Observing non-aggressive role models would have an inhibiting effect on the subsequent behaviour
The results for physical and verbal are much lower
ie. Girls with aggressive female - 5.5 and 13.7
Girls with non aggressive female - 2.5 and 0.3
Boys with aggressive male - 25.8 and 12.7
Boys with non aggressive male - 1.5 and 0
In Bandura’s study, how was hypotheses three proven?
3. Subjects will imitate the behaviour of a role model of the same sex to them
Yes - majority showed that
ie. Boys with aggressive male - 25.8 and 12.7
Boys with aggressive female - 12.4 and 4.3
In Bandura’s study, how was hypotheses four proven?
4. Boys are more likely to imitate aggressive behaviour than girls are
Boys showed higher physical aggression
ie. Boys with aggressive male - 25.8
Boys with aggressive female - 12.4
Girls with aggressive female - 5.5
Girls with aggressive male - 7.2
Girls showed higher verbal aggression
ie. Girls with aggressive female - 13.7
Girls with aggressive male - 2
Boys with aggressive male - 12.7
Boys with aggressive female - 4.3
Outline some of the qualitative findings in Bandura’s study
- Girls saw aggression as a male behaviour
ie. “That ain’t no way for a lady to behave”
“That girl…was just acting like a man”
- Both genders thought aggressive behaviour was acceptable
ie. “He’s a good fighter like Daddy”
What did Bandura conclude about his study?
- Role model was a stranger to child, so shows you can learn through imitation
- Observing behaviour produces imitative behaviour which would no have been expected if the behaviour hadn’t been observed
- Moved on from Skinner’s View that behaviour needs to be rewarded as children had no rewards
Was Bandura’s study ethnocentric?
Yes as other cultures may act or be brought up differently to not reproduce the aggressive behaviour
