CLASSICAL CONDITIONING UNIT 7- LEARNING LESSON 1
2
OBJECTIVES Define learning and provide examples. Identify John B Watson, BF Skinner, and Ivan Pavlov. Describe and apply the components of classical conditioning.
3
WARM UP Identify some of the things you’ve learned in the past few months.
4
LEARNING Learning IS… A relatively permanent change in behavior. Learning is NOT… Reflex: Simple, unlearned, controlled by the ANS Instinct: Inborn, complex pattern of a species
5
BEHAVIORAL PSYCHOLOGY Study of Stimulus-Response Learning Classical Conditioning (Ivan Pavlov, John B Watson) Operant Conditioning (BF Skinner) Cognitive/Social Learning Theory (Albert Bandura)
6
CLASSICAL CONDITIONING Stimulus in environment triggers response in subject. Ivan Pavlov (1849-1936) Physiologist researching digestion in dogs

ACTIVITY 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. http://www.worthpublishers.com/kolb/content/psychsim/index.htm http://bcs.worthpublishers.com/gray/content/psychsim5/Classical%20Conditioning/Classical Conditioning.htm http://bcs.worthpublishers.com/gray/content/psychsim5/Classical%20Conditioning/Classical Conditioning.htm
8
PAVLOV’S EXPERIMENT Before Conditioning (Pre-Learning) Ring bell (NS) No response from dog Food (UCS) Dog salivates automatically (UCR) During Conditioning (Learning) Ring bell (NS) Present food (UCS) Salivation (UCR) After Conditioning (Post-Learning) Ring bell (CS) Salivation to bell (CR)
9
GENERAL PRINCIPLES OF C 2 Acquisition Time period it takes for NS to be associated with UCS Generalization Stimuli similar to CS cause CR Discrimination Distinguishing between different stimuli Extinction Disappearance of CR to CS Spontaneous Recovery Previously extinguished CR returns suddenly
10
EMOTIONAL CONDITIONING John B. Watson Prove human emotion was result of conditioning Fear, rage, sadness 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
11
ALBERT ACTIVITY Set up experimental design. Give examples of generalization in experiment. Cite criticisms of experiment Identify ways researchers could help Albert get over his fears.
12
ALBERT ANSWERS Before: Rat No Response Loud noise Fear During: Rat Noise Fear After: Rat Fear Generalization: Rabbit Fur Coat Scary, fuzzy mask Criticisms: Screwed up normal kid Didn’t fix him
13
ALBERT ANSWERS Fixing Albert’s Fears Counter Conditioning: pleasant stimulus presented with fear object, re-condition Systematic Desensitization: gradually exposed to fear-evoking stimuli in pleasant circumstance Flooding: exposed to fear stimulus until response extinguished
14
OTHER EXAMPLES Associate song with relationship…break up, song makes you sad Taste Aversion – Got sick eating spaghetti, can’t eat it anymore (Garcia effect – biological component to conditioning – adaptive)
15
HOMEWORK Classical Conditioning Examples In examples provided, identify UCS UCR NS/CS CR
