Pavlov (1927) Experiment with Salivation in Dogs Flashcards
Background - Was investigating digestive process and functions within the cerebral cortex of the brain where reflexes were thought to occur and
dogs had to be fed before - salivated at footsteps and lab coats
What did Pavlov do to establish how the salivation and lab coats were linked?
He limited the direct contact that the dogs had with the experimenter and tried to introduce a neutral stimulus - metronome
When did Pavlov present the metronome?
Before the food appeared
Pavlov concluded that
environmental stimuli that previously had no relation to a reflex action, through repeated pairings, could trigger a salivation reflex
How many times did Pavlov find he had to pair the neutral stimulus and the food?
around 20 times
Pavlov found that
the dogs soon associated the ticking from the metronome with the presentation of the food and began to salivate at the ticking alone
Results from Pavlov’s experiments are
objective and scientific as Pavlov isolated the dogs therefore controlling the potential effects of any extraneouas variables on the conditioning process
Many of the expriments were repeated on multiple occasions where
Pavlov continually found that conditioned stimuli would produce a conditoned response, making it more reliable
Pavlov made assumptions about the pathways that existed and were being made in the cerebral cortex, without
being able to study the brain directly, therefore, his conclusions at the time may not have been completely accurate
Pavlov made the assumption that human reflexes would be conditioned in the same was as those in a dog so it is hard to
generalise his findings to humans as there are differences between the two. Although, classical conditioning is used to treat alcoholism so could be applied to humans
Used an artificial setting so
lacks ecological validity
Neutral stimulus?
metronome
Food?
Unconditioned stimulus
After several pairings the neutral stimulus becomes the
conditioned stimulus
The salivation becomes the
conditioned response
