Document Summary

Habituation a decrease in the strength of response to a repeated stimulus. Classical conditioning when an organism learns to associate two stimuli such that one stimulus comes to produce a response that was originally produced only by the other stimulus this form of learning occurs in most species. Pavlov was studying digestion in dogs by presenting dogs with different types of food and measuring. Acquisition refers to the period during which a response is being learned. **note: there are two terms for salivation: ucr and cr when the dog salivates to food, it is an unconditioned reflex (ucr), but when it salivates to a tone, it is a learned response (cr) Each presentation of the cs without the ucs is called an extinction trial. Even when a cr extinguishes, it can still reappear after a rest period without any new learning trials.
