pavlov

• initially bell wouldn't cause a response in the dog
• the dog would salivate when getting dinner
• before getting dinner Pavlov would ring the bell
• after repeating ringing the bell before eating the dogs will salivate at the sound of the bell which means they have become conditioned
• used a lab experiment
• a weakness of Pavlov's experiment is that if the conditioned response is presented on its own several times then the conditioning can be unlearned and become extinct
• a strength is that pavlov used a lab experiment which means it is standardised and can be repeated which increases the internal validity
• a weakness is that pavlov used dogs and humans so cannot be generalised
• a weakness is that the theory is deterministic because it does not take into account the idea of free will
