Pavlov's (1927) Salivating Dogs
- Procedure
- Results
- Conclusion
- Evaluation
LAB used dogs test salivation reflex by counting drops of saliva that fell
created chamber to eliminate all other possbile stimuli + extraneous variables (+ valid)
with metronome, salivation started after 9 seconds and by 45 seconds = 11 drops
could be a secondary conditioning when the 1st conditioned stimulus is paired with another neutral (buzzer)
eletric buzzer 5-10 secs after food = no salivation but before and during meat did
signalisation that links metronome to the food gives reflex
when repeated, same but ANY external stimuli could disrupt process
individual differences play a part
impossible to look at cerebral cortex functioning - complexity about the paths that develop that are hard to study
repeated for reliability, continually found same results = reliable
unable to measure brain activity @ time so was assumed = unreliable
pavlov thought findings generalisable to humans (evolution theory was around) but significant cognitive differences
- BUT CC been used to treat alcoholism = applicable?
artificial = lacks validity
