Michael Mann PSY2012 3-27-08 Chapter 5 Outline I. Definition of Learning II. Types of Learning A. It makes your mouth water: Classical conditioning 1. Pavlov and the salivation dogs * stumbled upon classical conditioning * classical conditioning - learning to make a reflex response to a stimulus other than the original, natural stimulus that normally produces the reflex a. Elements of classical conditioning 1. Unconditioned stimulus (UCS) * UCS- a naturally occurring stimulus that leads to an involuntary response 2. Uncondtitioned response (UCR) * UCR- an involuntary response to a naturally occurring or unconditioned stimulus 3. Conditioned stimulus (CS) * CS- stimulus that becomes able to produce a learned reflex response by being paired with the original unconditioned stimulus 4. Conditioned response (CR) * CR- learned relfec response to a conditioned stimulus b. Putting it all together: Pavlov's canine classic, or ding, dong, bell 2. Basic processes of classical conditioning a. Appetitive conditioning b. Aversive conditioning c. Extinction * the disappearance or weakning of a learned response following the removal or absence of the unconditioned stimulus ( in classical conditioning) or the removal of a reinforcer (in operant conditioning) d. Spontaneous recovery * the reappearance of a learned response after extinction has occurred e.

f. Stimulus discrimination * the tendency to stop making a generalized response to a stimulus that is similar to the original conditioned stimulus because the similar stimulus is never paired with the unconditioned stimulus g. Higher (second) order conditioning * occurs when a strong conditioned stimulus is paired with a neutral stimulus, causing the neutral stimulus to become a second conditioned stimulus h. External inhibition 3. Conditioned emotional responses: rats! a. Watson and Little Albert (CER and vicarious conditioning) * conditioned emotional response (CER)- emotional response that has become classically conditioned to occur to learned stimuli, such as a fear of dogs or the emotional reaction that occurs when seeing an attractive person * vicarious condtitioning- classical conditioning of a reflex response or emotion by watching the reaction of another person b. Other conditioned responses in humans * conditioned taste aversion- development of a nausea or aversive response to a particular taste because that taste was followed by a nausea
