Document Summary
Learning: process by which behaviour or knowledge changes as a result of experience. Classical conditioning: learning that occurs when neutral stimulus elicits response that was caused by another stimulus. Stimulus: external event or cue that elicits response: unconditioned stimulus (us): stimulus that elicits reflexive response without learning, unconditioned response (ur): reflexive, unlearned reaction to unconditioned stimulus. Pavlov - meat powder elicited unconditioned salivation. Neutral stimulus paired with and predicts unconditioned stimulus: tone was originally neutral because did not elicit response. Conditioned stimulus (cs): once neutral stimulus later elicits conditioned response because of it being paired with unconditioned stimulus. Conditioned response (cr): learned response that occurs to conditioned stimulus: to establish if conditioning takes place, cs must elicit salivation in absence of food. Salivation is ur if it occurs in presence of food (us), but is cr when it occurs after tone (cs) Connections between groups of neurons become strengthened during each instance of.
