What was discovered

While studying digestion in dogs, Pavlov observes that they begin salivating at a neutral stimulus (such as a sound) repeatedly paired with food, describing the conditioned reflex.

American psychologist Edwin Twitmyer published related findings a year earlier, without the impact of Pavlov's work.

What it led to

  • Experimental foundation of behaviourism (Watson, Skinner)
  • Behaviour-modification therapies
  • Neuroscience of conditioned reflexes and associative learning
