- Procedure
- The metronome ticks at a steady pace when the food is being presented. The dogs associated the ticking with the food
- Pavlov introduced a metronome(neutral stimulus) which they hadn't been in contact with before
- Pavlov thought they were responding to the lab coats as they associated the food with the lab coats
- He found them salivating before being presented with the food
- The dogs were fitted with tubes which collected their saliva
- He wanted to find out about the digestive system and the cerebral cortex where inbuilt reflexes occur
- Russian Psychologist who used dogs in lab conditions
- Pavlov 1927 Salivation in Dogs
- Further Research
- Pavlov tested reliability by carrying out further tests
- He used different stimuli- vanilla, shapes, colours. He found that they could associate with different things
- The conditioned stimuli has to be presented before the pairing (it doesn't work afterwards) However there could be a second condition (buzzer)
- Conclusion
- Signalisation in the brain links the metronome to the food
- Natural inborn reflexes are needed aswell
- Extraneous variables can easily interfere with conditioning
- Evaluation
- Objective
- Reliable as it has been conducted more than once
- He made assumptions about the cerebral cortex (low accuracy)
- Hard to generalize (doesn't co-inside with humans)
- Np ecological validity, done in a lab
- Further Research
- Environmental stimulus that hadn't been associated before could now trigger salivation through conditioning. Conditioned stimulus (ticking) triggered a conditioned response (salivation)
- Pavlov found that pairing took around 20 times to be an association
- Salivation to metronome= conditioned/salivation to food=unconditioned
