Document Summary
Learning: process by which behaviour/knowledge changes as a result of experience. Pavlov observed that dogs salivated before they were even presented with the food. Considered that if salivation occurs in anticipation of food, then perhaps salivary response can be learned. Conducted experiments in which a metronome would sound before presenting food to the dogs. Discovered that the dogs would start salivating at the sound of the metronome. Classical conditioning (pavlovian conditioning): learning that occurs when a neutral stimulus elicits a response that was originally caused by another stimulus. Unconditioned stimulus (us): stimulus that elicits a reflexive response without learning. Unconditioned response (ur): a reflexive, unlearned reaction to an unconditioned stimulus. Link between us and ur in pavlov"s experiment is unlearned; dog"s parent did not teach it to salivate at food, it does this naturally. Ex. flinching (ur) in response to loud noise (us)
