Winter Quarter, 2008 Reading Guide for Chapters 6 and 7 pp. 200-283 Week 4 This sheet is fairly comprehensive, but you should always refer back to the official fair game sheet posted online. This section is one of the most important to make your own examples! In doing so, don’t just use the ones from the book, think of your own. 1. Chapter 6 – Learning a. Pavlov and Classical Conditioning i. Ivan Pavlov 1. role – Russian psychologist. Nobel Prize for research on digestion 2. unconditioned reflex a. in your own words – automatic connections between a stimulus and a response b. example – food and secreting digestive juices 3. classical conditioning a. in your own words – process by which an organism learns a new association between two paired stimuli—a neutral and one that already evokes a reflexive response b. example – 4. unconditioned stimulus (UCS) a. in your own words – stimulus that consistently, automatically elicits a particular response b. example – food; electric shock 5. unconditioned response (UCR) a. in your own words – response to UCS b. example – salivation; shrieking and jumping 6. conditioned stimulus (CS) a. in your own words – response to it depends on the preceding conditions b. example – metronome; warning signal for shock 7. conditioned response (CR) a. in your own words – whatever response the conditioned stimulus begins to elicit as a result of the conditioning procedure b. example – salivation that follows metronome; tensing of the muscles and lack of activity 8. acquisition a. in your own words – process that establishes or strengthens a conditioned response [CS predicts the UCS] b. example – 9. extinction a. in your own words – to extinguish a classically conditioned response, repeatedly present the conditioned stimulus (CS) without the unconditioned stimulus (UCS) [CS no longer predicts UCS] b. example – buzz & puff of air = close eyes. Repeated buzzer w/out air. Eventually dont blink 10. spontaneous recovery a. in your own words – temporary return of an extinguished response after a delay b. example – after a while, a buzz will make you blink 11. stimulus generalization a. in your own words – extension of a conditioned response from the training stimulus to similar stimuli b. example – scared of a wasp after a bee sting [resemblance] 12. stimulus discrimination a. in your own words – different responses because two stimuli predicted different outcomes b. example – bell that signals end of class vs. fire alarm ii. explanations for classical conditioning (contingencies) - the longer the delay between the CS and the UCS, the weaker the conditioning, other things being equal. There must be contingency or predictability between them. © Thai Chu 2008
