1 Classical Conditioning Unit 7- Learning Lesson 1

2 Objectives Define learning and provide examples. Define learning and provide examples. Identify John B Watson, BF Skinner, and Ivan Pavlov. Identify John B Watson, BF Skinner, and Ivan Pavlov. Describe and apply the components of classical conditioning. Describe and apply the components of classical conditioning.

3 Warm Up Identify some of the things you’ve learned in the past few months. Identify some of the things you’ve learned in the past few months.

4 Learning Learning IS… Learning IS… A process leading to relatively permanent change in behavior. A process leading to relatively permanent change in behavior. Learning is NOT… Learning is NOT… Reflex: Reflex: Simple, unlearned behavior controlled by the ANS Instinct: Instinct: Inborn, complex pattern of behavior of a species

5 Behaviorists BF Skinner BF Skinner Behavior influenced by history of consequences John B. Watson John B. Watson Behaviorism Behaviorism Study of observable behaviors Study of observable behaviors

6 Behavioral Psychology Study of how our behavior results from stimuli in the environment and within ourselves. (Stimulus-Response Learning) Study of how our behavior results from stimuli in the environment and within ourselves. (Stimulus-Response Learning) Classical Conditioning Classical Conditioning Operant Conditioning Operant Conditioning Cognitive or Social Learning Cognitive or Social Learning

7 Think-Pair-Share “When I’m driving and see a stoplight turn red, I stop” “When I’m driving and see a stoplight turn red, I stop” Stimulus – red light Stimulus – red light Reaction – stop Reaction – stop Write down three more conditioned responses you do on a daily basis. Write down three more conditioned responses you do on a daily basis. Phone rings, pick it up Bell rings, you switch classes Teacher asks ?, you raise hand

8 Classical Conditioning Stimulus in environment triggers response in subject. Stimulus in environment triggers response in subject. Ivan Pavlov Ivan Pavlov (1849-1936) (1849-1936) Physiologist researching digestion in dogs Physiologist researching digestion in dogs

9 Activity PsychSim 4.0 “Classical Conditioning” PsychSim 4.0 “Classical Conditioning” This activity provides a review of Pavlov’s famous experiment on the salivary response in dogs, as well as the basic processes of classical conditioning: acquisition, generalization, discrimination training, and extinction.

10 Pavlov’s Experiment Before Conditioning (Pre-Learning) Before Conditioning (Pre-Learning) Ring tuning fork (NS)  No response from dog Ring tuning fork (NS)  No response from dog Food (UCS)  Dog salivates automatically (UCR) Food (UCS)  Dog salivates automatically (UCR) During Conditioning (Learning) During Conditioning (Learning) Ring fork (NS)  Present food (UCS)  Salivation (UCR) Ring fork (NS)  Present food (UCS)  Salivation (UCR) After Conditioning (Post-Learning) After Conditioning (Post-Learning) Ring fork (CS)  Salivation (CR) Ring fork (CS)  Salivation (CR)

11 Think-Pair-Share What other conditioned stimuli may have existed in Pavlov’s experiment? What other conditioned stimuli may have existed in Pavlov’s experiment?

12 General Principles of C 2 Acquisition Acquisition Time period it takes for NS to be associated with UCS Time period it takes for NS to be associated with UCS Generalization Generalization Stimuli similar to CS cause CR Stimuli similar to CS cause CR Discrimination Discrimination Distinguishing between different stimuli Distinguishing between different stimuli Extinction Extinction Disappearance of CR to CS Disappearance of CR to CS Spontaneous Recovery Spontaneous Recovery Previously extinguished CR returns suddenly Previously extinguished CR returns suddenly

13 Eye Blink Experiment UCS – puff of air in eye UCS – puff of air in eye UCR – blink UCR – blink NS – tone NS – tone CS – tone CS – tone CR – blink CR – blink

14 Emotional Conditioning John B. Watson John B. Watson Prove human emotional reaction was result of conditioning Prove human emotional reaction was result of conditioning Fear, rage, sadness Fear, rage, sadness Little Albert Little Albert http://video.google.com/videoplay?docid=- 8331168072486928717&q=Classical+Conditioning& hl=en http://video.google.com/videoplay?docid=- 8331168072486928717&q=Classical+Conditioning& hl=en http://video.google.com/videoplay?docid=- 8331168072486928717&q=Classical+Conditioning& hl=en http://video.google.com/videoplay?docid=- 8331168072486928717&q=Classical+Conditioning& hl=en

15 Albert Activity Set up experimental design. Set up experimental design. Give examples of generalization in experiment. Give examples of generalization in experiment. Cite criticisms of experiment Cite criticisms of experiment Identify ways researchers could help Albert get over his fears. Identify ways researchers could help Albert get over his fears.

16 Albert Answers Before: Rat  No Response Loud noise  Fear During: Rat  Noise  Fear After: Rat  Fear Generalization: Generalization: Rabbit Fur Coat Criticisms: Criticisms: Screwed up kid Didn’t fix him

17 Albert Answers Fixing Albert’s Fears Fixing Albert’s Fears Counter Conditioning: pleasant stimulus presented with fear object, re-condition Counter Conditioning: pleasant stimulus presented with fear object, re-condition Systematic Desensitization: gradually exposed to fear-evoking stimuli in pleasant circumstance Systematic Desensitization: gradually exposed to fear-evoking stimuli in pleasant circumstance Flooding: exposed to fear stimulus until response extinguished Flooding: exposed to fear stimulus until response extinguished

18 Other Examples Associate song with relationship…break up, song makes you sad Associate song with relationship…break up, song makes you sad Associate smells Associate smells Taste Aversion – Got sick eating spaghetti, can’t eat it anymore Taste Aversion – Got sick eating spaghetti, can’t eat it anymore
