US- unconditioned stimulus- a stimulus that automatically leads to an observable response prior to any training. NATURAL STIMULUS (Presenting Food) UR- unconditioned response- the observable response that is produced automatically, prior to training, on presentation of an unconditioned stimulus. NATURAL RESPONSE (Salivating) CS- conditioned stimulus- the neutral stimulus that is paired with the unconditioned stimulus during classical conditioning (Ringing the Bell) CR- conditioned response- the acquired response that is produced by the conditioned stimulus in anticipation of the unconditioned stimulus. (Salivating) Forming the CS-US connection- CS should function as a signal that the US is about to occur Acquisition- conditioned response becomes stronger with repeated CS-US pairings. the more times a dog hears the CS(tone) paired with the US(food), the stronger the CR becomes Extinction- CR diminishes when the CS is presented repeatedly without the US Spontaneous Recovery- CR that has disappeared in extinction is recovered spontaneously with the passage of time. after extinction, a dog no longer responds to the CS. after a rest period the dog will again respond when presented with CS Stimulus Generalization- when a new stimulus that resembles...
