- accidental discovery of conditioned response in dogs while studying digestive glands; started with a mentalistic approach, but then turned to a more objective approach; tested multiple stimuli and and determined that many could produce CR if it didn't elicit anger or fear; collected saliva to determine how much and when dogs salivated

- presentation of CS and US together; after a number of pairings an association forms; long program; rigorous methodology

- designed cubicles to control for outside variables; researcher could operate CS, present food, and collect saliva without being seen by animal; constructed the "Tower of Silence" that eliminated noise, temperature extremes, odors, etc. that could influence animals
