Document Summary
The early years of classical conditioning: pavlov discovered the fact that dogs secreted stomach juices in response to the sight of food through his studies of digestion. The classical conditioning paradigm: food = unconditional stimulus (us, salivation = unconditioned response (ur, tone = conditioned stimulus (cs, salivation = conditioned response (cr) Experimental situations: now we have conducted classical conditioning experiments with a variety of different species unlike pavlov that focused mainly on the salivation of dogs. Excitatory pavlovian conditioning methods: everything that we have learned so far are instances of excitatory pavlovian conditioning organisms learn a relation between a cs and us. Intertrial interval: the time from the end of one conditioning trial to the start of the next trial. Interstimulus interval: the time from the start of the cs to the start of the us in a conditioning trial, also called the cs-us interval.
