Learning Theories Flashcards
Bandura (1961)
Aggressive VS non-aggressive role models.
72 children, 24 with aggressive role model, 24 with non-aggressive role model, 24 in control group.
Aggressive role model = verbal + physical aggression.
Little aggression in non-aggressive role model and control groups.
Male role models had bigger influence.
Bandura (1963a)
If children would be more aggressive when watching a film or cartoon.
96 children - 48 boys, 48 girls, aged 3-5.
Bandura concludes that children will imitate filmed aggression in the same way as live aggressive role models.
Bandura (1965)
To see when a role model is rewarded or punished and how likely the children are to imitate.
66 children - 33 boys, 33 girls, aged 3-5.
Children less likely to imitate if role model is punished, but can still imitate.
Can still imitate with no consequence.
Can still imitate if given incentives.
What is classical conditioning?
Learning by association.
Before conditioning — Neutral Stimulus -> No Response.
During conditioning — Neutral Stimulus -> Unconditioned Stimulus -> Unconditioned Response.
After conditioning — Neutral Stimulus -> Conditioned Response.
It is artificial.
What was the AIM of Watson & Rayner’s (1928) study?
To find out if classical conditioning works on humans.
More specifically, to find out if a fear responds can be conditioned into a 9 month old baby boy.
Also, to see if the fear response will be generalised to other animals and objects.
What was the SAMPLE of Watson & Rayner’s (1928) study?
One boy, 9 months old, Albert B.
He was 11 months old when the conditioning began.
His mother was a wet nurse at the hospital and Albert was chosen because he seemed healthy and quire fearless.
Opportunity sample.
What was the PROCEDURE of Watson & Rayner’s (1928) study?
9 months old — Albert was tested with a white rat, and other stimuli to see if he had a fear reaction. He didn’t; this shows they were Neutral Stimuli (NS). They also banged an iron bar to check his fear response, which he cried to; this shows the noise was an Unconditioned Stimulus (UCS) and crying was an Unconditioned Response (UCR).
11 months old — Albert was conditioned. He was shown the white rat 3 times, and it was paired with the iron bar. Albert whimpered & was presented with this again one week later.
What was the RESULTS of Watson & Rayner’s (1928) study?
Albert then whimpered when the rat was presented alone.
This suggests that the NS is now a Conditioned Stimulus (CS) and Albert’s crying is a Conditioned Response (CR).
They tested Albert’s reaction to other white fluffy things, and he showed similar fear responses to the rabbit and Santa mask. This is generalisation of response.
What was the CONCLUSIONS of Watson & Rayner’s (1928) study?
They had successfully conditioned Albert to fear the white rat and that his fear response generalised to other white, fluffy things and transferred to other situations (lecture theatre).
The conditioning lasted over a month, and Watson proposed the conditioned fear responses would stay with Albert for a lifetime.
Evaluation of Watson & Rayner (1928).
Generalisability — it was done on a single child, so it is unrepresentative as the baby may be unusual in many different ways. If Albert wasn’t a healthy child, then the results cannot be generalised to all children.
Reliability — it has standardised procedures and was carefully documentated and filmed, which means it can be easily replicated, and has inter-rater reliability.
Application — it has lead to research into therapies like systematic desensitisation, where the patient uses a fear hierarchy to approach their phobia.
Validity — the study has careful controls, e.g., Watson hiding behind a curtain while hitting the iron bar. However, it lacks ecological validity because Albert was in an artificial environment, taken away from his familiarity.
Ethics — the study is clearly unethical as they deliberately caused distress to an infant and continued when he was upset (ignored principle of reducing harm). Albert’s mother gave consent and was present the whole time (valid presumptive consent) and she was able to withdraw him, and in fact did so.
What is conditioned extinction recovery?
Extinction is when conditioned stimuli gradually lose their association with the original unconditioned stimuli and they revert back to being a neutral stimulus again.
Recovery is when an association has formed, and it is never truly forgotten. Even after extinction, a conditioned response can reappear.
What is stimulus generalisation?
Once a conditioned response is formed, there is a tendency for it to reappear in response to things other than the original conditioned stimulus.
What was the AIM of Ivan Pavlov’s (1927) study?
To find out if a reflexive behaviour can be produced in new situations through learning.
In particular, to see if associating a reflex with a neutral stimulus (a sound) causes learning to take place, producing a conditioned reflex in new situations.
What was the PROCEDURE of Ivan Pavlov’s (1927) study?
Variety of 35 dog breeds.
Pavlov placed each dog in a sealed room that didn’t;t allow the dog to see, hear or smell anything from outside.
Dog was strapped to harness to stop it from moving about and its mouth was linked to a tube that drained saliva away.
Dog salivated to food (control condition).
Dog didn’t salivate to tuning fork.
Pairs sound with food multiple times until the sound alone causes dog to salivate.
What was the RESULTS of Ivan Pavlov’s (1927) study?
After 20 trials of sound and food together, Pavlov would use just the sound and could produce saliva.
Pavlov found that the conditioned dog started to salivate after 9 seconds after hearing the sound, and by 45 seconds had produced 11 drops of saliva.
