Very detailed mind maps of Edexcel A level Learning Theories Psychology notes - these helped me get an A* at AS and predicted an A* for my A level
It includes the AO1 details of the studies and theories you need to know and also the AO3 evaluation
This is the whole package of learning theories ps...
SCOUT
• Takes place when two stimuli are repeatedly paired together Supporting Evidence:
Before Conditioning: UCS triggers a reflex response • Ivan Pavlov (dog experiment)
Unconditioned Unconditioned • Watson and Rayner (Little Albert)
Stimulus Response • Mirte Brom (Human sexual responses)
During Conditioning: The UCS and the NS are experienced close • Bagby (Fear of running water—foot got trapped near waterfall)

Criticing the evidence:
After Conditioning: The NS produces the same response as UCS so
it is not the CS and the response is the CR • Only explains how a limited range of behaviours can be
acquired
Conditioned Stimulus Conditioned Response
• Only explains acquisition of simple reflex responses
Other Theories
• Operant Conditioning
• When the CS is experienced without the UCS over a period of

time, the CR is extinguished.

• Generally responses are weaker than the original ones • Poor external validity (Pavlov’s dogs kept unnaturally)
• Empirical (observable) data

Generalisability:
• Exploring the role of conditioned reflexes in the eating
behaviour of dogs • Experiment conducted on dogs and there is a problem generalising the results of animal studies to
humans
• Exploring how salivation becomes associated with new
• However in Watson and Rayner’s study they found that classical conditioning does take place in
stimuli apparently unrelated to food and the
humans
properties of this association
Reliability:
• This is a reliable study because it has standardised procedures and it was carefully documented
• Pavlov did this experiment again and again over 25 years with different breeds of dog but with different
neutral stimuli– good test-retest reliability
• Done in a laboratory so the production of saliva could be • He got different researchers to observe the dog and measure of the saliva—
easily observed and measured either by volume or no. of good inter-rater reliability

Applications:
• Salivation was the dependent variable
• Further research into classical conditioning in humans e.g Watson and Rayner
• Took place in a sound proof chamber in order to minimise
the effects of extraneous variables such as noise
Validity:
• Pavlov established a baseline by measuring salivation in
• Reduced the impact of extraneous variables enhancing the internal
