Chapter 5: Learning I. Learning a. Relatively permanent, change in behavior due to experience b. Not explained by i. Native response tendencies ii. Maturation iii. Temporary states (fatigue, drugs) iv. Stimulus in environment affects organism v. Response what organism does in reaction to stimulus vi. Consequence – after response vii.Stimulus-Stimulus Learning 1. Learning to associate one stimulus with another a. Thunder/lightning viii. Response Consequence Learning 1.

Digestion in dogs – salivary reflex d. Measured saliva e. Present food to dog and after a while, dogs salivated before food arrived f. Dogs were associating presence of food bringer (researcher) with food g. Unconditioned Stimulus (US)– Elicits unconditioned response i. Pavlov’s study – Food h. Unconditioned Response (UR) – occurs due to presentation of unconditioned stimulus i. Neutral Stimulus (NS) – doesn’t elicit unconditional response; becomes conditioned stimulus ( CS) j. Acquisition Stage – initial stage in classical conditioning; association between NS and US takes place; NS comes before US; should be ½ second apart k. Extinction - after CR is established, just CS is expressed, then CR is weakened l. Spontaneous Recovery – take time after extinction and then do CS alone and you get a small CR m. Stimulus Generalization – Tends to respond to stimuli similar to CS
