Ch.9 L.1 September 30, 2011 Unit 4 Learning and Cognitive Processes Chapter 9 Learning: Principles and Applications Lesson 1 Classical Conditioning Objectives: Describe the principles of classical conditioning Outline the techniques of classical conditioning Sep 269:33 AM 1 Ch.9 L.1 September 30, 2011 Learning What is learning? How do we know that learning has occurred? What factors, other than learning, can influence performance? Sep 269:37 AM 2 Ch.9 L.1 September 30, 2011 Learning Learning can be defined as a relatively permanent change in behaviour that results from experience Sep 269:48 AM 3 Ch.9 L.1 September 30, 2011 Classical Conditioning Classical conditioning is a learning procedure in which associations are made between a natural stimulus and a learned, neutral stimulus. Neutral Stimulus a stimulus that does not initially elicit a response (tuning fork) Unconditioned Stimulus (UCS) an event that elicits a certain predictable response without previous training (meat) Unconditioned Response (UCR) An organism's automatic (or natural) reaction to a stimulus (salivation) Conditioned Stimulus (CS) An ordinarily neutral event that, after training, leads to a response. Conditioned Response (CR) The learned reaction to a conditioned stimulus Sep 269:45 AM 4 Ch.9 L.1 September 30, 2011 Classical Conditioning Sep 269:39 AM 5 Ch.9 L.1 September 30, 2011 Principles of Classical Conditioning Generalization When an animal responds to a second stimulus similar to the original CS, without prior training (dogs responded to an oval as well as a circle) Discrimination The ability to respond differently to similar but distinct stimuli. (dentist's drill, other drills) Extinction The gradual disappearance of a CR when the CS is repeatedly presented without the UCS. (eg car accident) how can this be applied to daily life? Think of examples from your own experience in which you have developed a conditioned response Conditioned Stimulus Conditioned Response Similar Stimulus Sep 2610:07 AM 6 Ch.9 L.1 September 30, 2011 Classical Conditioning and Human Behaviour We have Watson and Rayner's experiment with little Albert and the rat (1920). For this experiment, identify: UCS UCR CS CR How did this experiment also show the principal of generalization? Mowrer's "bell and pad" how does this use classical conditioning? Sep 309:46 AM 7
