pavlov Flashcards
what was pavlovs aim?
• wanted to study the cerebral cortex in dogs
• wanted to see if dogs could be classically conditioned
what was pavlovs procedure?
• paired a metronome bell (unconditioned stimulus) with food which triggered salivation (unconditioned response)
• dog eventually started to salivate at the bell (conditioned response)
how did pavlov control extraneous variables?
• built a chamber for the dog so they couldn’t hear footsteps
• followed a standardised procedure
how many times did conditioning occur for pavlov’s dogs to salivate?
• around 20 times
when did pavlov’s dogs start to salivate and for how long for?
• after 9 seconds
• after 45 seconds, 11 drops of saliva were collected
what were pavlovs weaknesses?
• low generalisability as dogs are very different from humans. humans are smarter as they have a more developed cerebral cortex than dogs
• low validity due to low ecological validity: the situation would not occur in everyday life
• low in ethics as it is widely considered unethical and inhumane
what are pavlov’s strengths?
• high applications for example pet training, advertising, education and mental health - lead to the development of S.D and flooding
• high reliability as he used a large sample size and tested on not just the metronome bell but buzzers and other stimuli too. he also used a standardised procedure.
• objective and credible results
