February 7 th Lecture: Learning Defined : any relative permanent change in behavior that occurs because of experience Conditioning :a kind of learning that involves associations between environmental stimuli and responses Types of Conditioning Classical Conditioning: (Pavlov)- the organism learns to associate two stimuli, one produces a response that originally was only produced by the other classic example of dog/bell and salivation( and “the office” recreation of this) Unconditioned Stimulus (US): response which is unconditioned Unconditioned Response (UR): response that is automatically produced (salivate) Conditioned Stimulus (CS): originally neutral stimulus that elicits a behavior being paired with a unconditioned stimulus(bell) Conditioned Response (CR): response elicited by the conditioned stimulus(salivate to bell) Classical Conditioning #1-video about conditioning a blink response – woman blinks b/c of a bell because she associates with a puff of air Classical conditioning #2-video about dog on shock machine… metronome then causes dog to react defensively (shock is unconditioned stimulus, unconditioned response is defensive behavior, conditioned stimulus becomes metronome , conditioned response is defensive behavior to metronome) Practical Application of Pavlov and Classical Conditioning: Extinction:repeat the conditioned stimulus without the unconditioned stimulus over time and conditioned response will disappear Spontaneous Recovery: after a response has been extinguished it may spontaneously reappear after the passage of time with exposure to the conditioned stimulus Higher Order Conditioning: pairing a neutral stimulus with the conditioned stimulus will create another conditioned stimulus, although a weaker conditioned response. More likely to become extinct (food with bell, bell with light) Stimulus generalization: after a stimulus response becomes a conditioned stimulus

for some response, other similar stimuli may produce the same reaction Stimulus discrimination: one learns to realize the differences between similar stimuli(ex: fire alarm and alarm clock) Little Albert Movie- unconditioned stimulus was loud noise and response was startled noise, then conditioned stimulus was white rat and startled response to that (it generalized to a fur hat, and a bunny, all fuzzy things) Anticipatory Nausea and Vomiting –classically conditioned response, chemotherapy(UCS), Nausea(UCR), treatment room/needles(CS), nausea in response to the room(CR) ANV patients don’t respond well to anti-nausea drugs, responsive to some behavioral treatments (so the doctor isn’t always associated with bad things) Operant Conditioning/Instrumental Learning Behavior is dependent on its consequences Thorndike: Studied cats. Law of Effect:
