Chapter 7 Learning Classical Conditioning *The story of Pavlov and his dogs lead to a breakthrough in learning theory that is now called Classical Conditioning * Unconditioned Stimulus ( UCS ): stimulus that can elicit an unlearned response (an instinctual stimulus) (not learned) * Unconditioned Response ( UCR ) : an unlearned reaction to the unconditioned stimulus (an instinctual or inborn reaction) * Conditioned Stimulus ( CS ) : stimulus that elicits a response as a result o being paired with an unconditioned stimulus (a learned stimulus) * Conditioned Response ( CR ) : response that is similar or identical to the unconditioned response that is elicited by a conditioned stimulus ( a learned response) *Definition: a form of learning in which a previously neutral stimulus (CS) is paired with an unconditioned stimulus (UCS) to elicit a conditioned response (CR) that is identical to or very similar to the unconditioned response (UCR) Classical Conditioning Cont. = learning through association * “Little Albert” experiment (John Watson): paired a white rat with a frightening noise until the baby was conditioned to be afraid of the white rat on site (after 7 pairings) What’s the Unconditioned Stimulus? Loud Noise What’s the Unconditioned Response? Fear What’s the Conditioned Stimulus? White Rat What’s the Conditioned Response? Fear * Counterconditioning: the process of reversing classical conditioning by pairing the conditioned stimulus with a new unconditioned stimulus for a response that is stronger than

the conditioned response *For little “Albert” we might pair the rat with cookies until he is no longer afraid of the rat Rat becomes the UCS. ..Cookies become new CS h Tell me a story about a time where you were classically conditioned…Apply all terms correctly. h In Class Examples… *Some things that we can understand through Classical Conditioning… Fear responses Sentimental feelings Food likes/dislikes Responses to medical treatments (chemo) + sentimental feelings: UCS=falling in love UCR=feel good CS=song CR=feel good Fear Response: chucky UCS=killer doll/chucky UCR=fear CS=any doll CR=fear Chemo: UCS=chemo UCR=nausea CS=song/nurse CR=nausea + Operant Conditioning *Definition: Learning in which the consequences of behavior lead to changes in the probability of the behavior’s occurrence (all about consequence.
