AP PSYCHOLOGY-Period 4 CLASSICAL CONDITIONING & OBSERVATION/SOCIAL LEARNING REVIEW Classical Conditioning: - Learning in which a neutral stimulus (NS) is paired with something that automatically causes a response in the subject (UCS) until the neutral stimulus (NS) produces a response. *An example of classical conditioning was the coin shaking experiment that we did in class. Key Terms: -Unconditioned Stimulus (US or UCS) -Unconditioned Response (UR or UCR) -Conditioned Response (CR) -Conditioned Stimulus (CS) -Neutral Stimulus (NS) -Acquisition -Extinction -Generalization -Discrimination -Spontaneous Recovery Key Psychologists: -Ivan Pavlov- Pavlov’s dog -John B. Watson- Little Albert -John Garcia and Koelling study Classical Conditioning was identified by Ivan Pavlov. Pavlov conducted an experiment in which he taught dogs to salivate to a bell. Unconditioned Stimulus- a stimulus that unconditionally, naturally, and automatically triggers a response Unconditioned Response- the unlearned, naturally occurring response to the unconditioned stimulus Conditioned Response- the learned response to a previously neutral (but now conditioned) stimulus Conditioned Stimulus- an originally, irrelevant stimulus that after association with an unconditioned stimulus, comes to trigger a conditioned response (same as the NS) Neutral Stimulus- a stimulus which initially produces no specific response other than focusing attention (same as the CS) Classical Conditioning Formula: NS → nothing NS + UCS → UCR CS → CR Examples: 1.) 2.) A man has a terrible fear of snakes. Whenever this man is given a Dr. Pepper, he is shown a snake immediately following. Soon after, the man will begin to tremble with fear as soon as he sees a Dr. Pepper. NS= Dr. Pepper UCS= Snake CS= Dr. Pepper UCR= fear CR=fear Acquisition- learning begins with an association between a CS and a UCS Extinction- the process of unlearning a behavior (when CS no longer causes the CR) Generalization- the tendency to respond to a similar CS (dogs respond to all types of bells, not just the one they were trained/conditioned with) Discrimination- when the subject is trained to tell the difference between various stimuli Spontaneous Recovery- when the behavior resumes when the CS again is presented with the UCS after extinction and a rest period -John Garcia and Robert Koelling studied taste aversions. They performed an experiment showing how rats more readily learned to make certain associations than others. They used four groups of subjects in their experiment and exposed each to a particular combination of CS and US. The rats learned to associate noise with shock and unusual nausea. However, they were unable to make the connection between noise and nausea and between unusual-tasting water and shock. CS Loud Noise Loud Noise Sweet water Sweet water US Shock Radiation (nausea) Shock Radiation (nausea) Learned Response Fear Nothing Nothing Avoid water -John B. Watson conducted the Little Albert experiment. He classically conditioned and 11 month old baby to fear white rats. The baby was originally afraid of loud noises so Watson conditioned him to fear white rats by pairing the 2 together. Observation learning/Social learning: - When you learn by watching, observing, and/or imitating other (older siblings, famous people, parents, etc.) Key Terms: Key Psychologist: -Latent learning -Cognitive Map -Modeling -Vicarious reinforcement -Mirror neurons -Albert Bandura- BoBo Doll study Modeling- a form of learning where individuals act or perform by observing another individual Mirror Neurons- when you watch someone do something, then you go try it yourself Vicarious reinforcement- you are more likely to repeat behaviors that others get rewarded for performing Latent learning- learning that occurs but you don’t really know you’re leaning until you do it - Example: your mom drives to your grandma’s house every day while you’re in the car with her. One day, you have to drive there by yourself, and you already know the way even though you have never driven there before. Cognitive Map- mental representation of the layout of one’s environment - Example: when a friend asks you directions to your house you are able to create an image in your mind of the roads, places to turn, landmarks, etc. to explain how to get there. -Albert Bandura conducted the BoBo Doll experiment. Bandura had an adult and a child in a room. He had the adult pound, kick, and throw an inflated BoBo doll around the room while yelling “sock him in the nose…hit him…kick him…” While this was going on, the child was observing. After observing, the child was taken in another room with many other toys including the BoBo doll. The children who had witnessed the aggressive adult models displayed very similar aggressive behavior towards BoBo to that which they had observed. The children in the control group were much less likely to aggress against BoBo. QUIZ CLASSICAL CONDITIONING & OBSERVATION/SOCIAL LEARNING 1. Lisa normally feeds her cat canned cat food. She noticed that every time she uses her electric can opener, her cat comes to the kitchen. What is the conditioned stimulus? A) the cat food B) the sound of the electric can opener C) the cat coming to the kitchen D) Lisa 2. Who first identified the form of learning called classical conditioning? A) John Watson B) Ivan Pavlov C) John Garcia D) B. F. Skinner 3. Albert Bandura’s work evidenced that children who witnessed aggressive behavior on the part of adults would be likely to imitate the aggressive behavior later on. This phenomenon is known as A) modeling B) instrumental learning C) the copycat effect D) classical conditioning 4. Which classical conditioning term best describes the following scenario: Later in his classical conditioning experiments, Pavlov’s dogs began to salivate whenever they heard any sound similar to a bell, such as a doorbell or someone accidently clinking a water glass. A) discrimination B) spontaneous recovery C) unconditioned response D) generalization 5. A researcher who concludes that “people who watch graphic violence in films are more likely to behave in violent ways than people who don’t” is probably researching what kind of learning? A) latent B) behavioral C) observational D) insight 6. When a CS is not followed by a UCS, the subsequent fading of a CR is called A) discrimination B) generalizing C) delayed reinforcement D) extinction 7. The classic BoBo doll study, where a child punched a doll after seeing an adult do the same, was a demonstration of A) classical conditioning B) observational learning C) latent learning D) operant learning 8. Pavlov is to classical conditioning as ________ is to _________. A) Bandura; observational learning B) Skinner; latent learning C) Thorndike; modeling D) Garcia; computer assisted instruction 9. The sudden reappearance of a response after a period of extinction is known as: A) stimulus generalization B) extinction C) stimulus discrimination D) spontaneous recovery 10. In the experiment with little Albert, the conditioned stimulus was A) the mattress Albert sat on B) the loud noise C) the laboratory D) the rat Match the following terms with the correct definition. 1. Unconditioned Stimulus a. the learned response to a previously neutral (but now conditioned) stimulus 2.
