Pavlov (1927) experiment Flashcards
what did Pavlov’s experiment explain
how can unconditioned stimulus elicits an unconditioned response
give 2 aims of the experiment
to study how the cerebral cortex works in making associations
exploring how salivation becomes associated with the new stimuli
how many dogs were used in total
35
describe the procedure
1) dog was restrained in a harness and isolated from distractions
2) NS presented (bell or buzzer) using a remote control, he presented the dog with food
3) a tube from the dog’s mouth carried salvia to a container, where it was measured
what was the NS
bell or buzzer
what was the UCS
food
what was the UCR
salivation
what was the CS
bell or buzzer
what was the CR
salivation
how many saliva drops had been collected after 45 seconds
11 drops
give 2 results from the experiment
conditioning is found the be sensitive to extraneous variables
signalisation in the brain that links the bell to food and gives us the reflex response
give 1 point around generalisability
low generalisability- humans are more complex- reduced credibility of results
give 1 point around reliability
high reliability- uses the same dog, consistency in results, improving accuracy
give 2 points of application
high application, led to further explanation of phobias, used to treat alcoholism
high application- aversion therapy for unwanted habits (smoking), led to using injections to make them sick whenever they are around habits
give 3 validity points
low ecological validity/ double steel doors/ lack of mundane realism
low task validity/ fed through remote control/ not accurate mundane realism
high validity/ repeated 20 times/ reduces anamolies
