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 and unlearned response (and instinctual stimulus) 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 of being paired with and unconditioned stimulus (a learned stimulus) Conditioned Response ( CR ) : response that is similar or identical 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. “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 (cs) with a new unconditioned stimulis (ucs) for a response that is stronger than the conditioned response (cr) For little “Albert” we might pair the rat with cookies until he is no longer afraid of the rat Tell me a story about a time where you were classically conditioned… Apply all terms correctly. In Class Examples… 1. Clowns: 1. Ucs: killer clown 2. Ucr: fear 3. Cs: all clowns or clown related 4. Cr: fear Some things that we can understand through Classical Conditioning Operant Conditioning Definition: Learning in which the consequences of behavior lead to changes in the probability of the behavior’s occurrence There are four ways in which the consequences of our behavior can be influenced: 1. Positive reinforcement 2.
