    • 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
