4 LO 5.1 Learning What is Learning? Learning – any relatively permanent change in behavior brought about by experience or practice. When people learn anything, some part of their brain is physically changed to record what they have learned. Any kind of change in the way an organism behaves is learning.

5 Pavlov and Classical Conditioning
LO Classical conditioning AP Key contributors to the study of learning Pavlov and Classical Conditioning Ivan Pavlov – Russian physiologist (person who studies the workings of the body) who discovered classical conditioning through his work on digestion in dogs. Classical conditioning - learning to make a reflex response to a stimulus other than the original, natural stimulus that normally produces the reflex. Copyright © 2011 Pearson Education, Inc.

7 Classical Conditioning Concepts
LO Classical conditioning AP Classical conditioning phenomena Classical Conditioning Concepts Unconditioned stimulus (UCS) - a naturally occurring stimulus that leads to an involuntary response. Unconditioned means “unlearned” or “naturally occurring.” Unconditioned response (UCR) - an involuntary response to a naturally occurring or unconditioned stimulus. UCS – ice cream UCR - salivation Copyright © 2011 Pearson Education, Inc. All rights reserved. Menu

8 Classical Conditioning Concepts
LO Classical conditioning AP Classical conditioning phenomena Classical Conditioning Concepts Conditioned stimulus (CS) - stimulus that becomes able to produce a learned reflex response by being paired with the original unconditioned stimulus. Conditioned means “learned.” A neutral stimulus can become a conditioned stimulus when paired with an unconditioned stimulus. Conditioned response (CR) - learned reflex response to a conditioned stimulus. Sometimes called a conditioned reflex. CS – ice cream truck CR – salivation when hear ice cream truck bell Copyright © 2011 Pearson Education, Inc. All rights reserved.

9 Acquisition - the repeated
LO Pavlov’s classic experiment in conditioning AP Classical conditioning phenomena Acquisition - the repeated pairing of the NS and the UCS; the organism is in the process of acquiring learning.

10 Classical Conditioning Concepts
LO Classical conditioning AP Classical conditioning phenomena Classical Conditioning Concepts Although classical conditioning happens quite easily, there are a few basic principles that researchers have discovered: The CS must come before the UCS. The CS and UCS must come very close together in time—ideally, only several seconds apart. The neutral stimulus must be paired with the UCS several times, often many times, before conditioning can take place. The CS is usually some stimulus that is distinctive or stands out from other competing stimuli. Copyright © 2011 Pearson Education, Inc. All rights reserved.

12 Classical Conditioning Concepts
LO Classical conditioning AP Differences between types of learning Classical Conditioning Concepts Stimulus generalization - the tendency to respond to a stimulus that is only similar to the original conditioned stimulus with the conditioned response. 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. Extinction - the disappearance or weakening 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).

13 Classical Conditioning Concepts
LO Classical conditioning AP Classical conditioning phenomena Classical Conditioning Concepts Spontaneous recovery – the reappearance of a learned response after extinction has occurred. Learning is a relatively permanent change in behavior. Higher-order conditioning - occurs when a strong conditioned stimulus is paired with a neutral stimulus, causing the neutral stimulus to become a second conditioned stimulus.

16 Conditioned Emotional Response
LO Conditioned emotional response AP Emotional learning… Conditioned Emotional Response 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. CERs may lead to phobias – irrational fear responses. Menu Copyright © 2011 Pearson Education, Inc. All rights reserved.

18 LO 5.3 Conditioned emotional response
AP …taste aversion, … Taste Aversion Vicarious conditioning - classical conditioning of a reflex response or emotion by watching the reaction of another person. Conditioned taste aversion - development of a nausea or aversive response to a particular taste because that taste was followed by a nausea reaction, occurring after only one association. Biological preparedness - the tendency of animals to learn certain associations, such as taste and nausea, with only one or few pairings due to the survival value of the learning.

19 Why Classical Conditioning Works
LO Classical conditioning Why Classical Conditioning Works Stimulus substitution - original theory in which Pavlov stated that classical conditioning occurred because the conditioned stimulus became a substitute for the unconditioned stimulus by being paired closely together. Cognitive perspective - modern theory in which classical conditioning is seen to occur because the conditioned stimulus provides information or an expectancy about the coming of the unconditioned stimulus.
