3. How Do We Learn? Learning is defined as a relatively permanent change in an organism’s behavior due to experience (nurture). Learning is defined as a relatively permanent change in an organism’s behavior due to experience (nurture). Most learning is associative learning: learning that certain events occur together. Most learning is associative learning: learning that certain events occur together. There are 3 main types of Learning: There are 3 main types of Learning: 1. Classical Conditioning 1.

5. Behaviorism focuses on Learning John Watson is generally considered the father of behaviorism. John Watson is generally considered the father of behaviorism. Behaviorism focused on: Behaviorism focused on: 1. Making psychology an objective science 2. Studying behavior without reference to mental processes (early behaviorists like Watson will ignore cognition but most recognize its importance today.)

6. John Watson: the Father of Behaviorism Focused on external behavior Focused on external behavior Believed Nurture was more important than nature. Believed Nurture was more important than nature. Give me a dozen healthy infants, well- formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select – doctor, lawyer, artist, merchant-chief and, yes, even beggar- man and thief….

7. Type of Learning 1: Classical Conditioning (Pavlovian Conditioning) Terms you must understand: Terms you must understand: 1. Unconditioned means it is unlearned and comes naturally. Ex: salivating when presented with food. 2. Conditioned means it is learned and the response does not come naturally. Ex: getting up when school bell rings. 3. Response: is a behavior done in response to the stimulus, like salivating. 4. Stimulus: external thing that may cause a behavior like a bell or food.

8. Father of Classical Conditioning is Ivan Pavlov Russian physician/ neurophysiologist Russian physician/ neurophysiologist Was studying digestive enzymes in dogs when he accidentally realized the importance of associative learning which would consume his research for rest of his life.

9. Classical Conditioning (Pavlovian Conditioning) Classical Conditioning is a type of learning in which an organism comes to associate stimuli. Ex: tone and food. Classical Conditioning is a type of learning in which an organism comes to associate stimuli. Ex: tone and food. Begins with a reflex which is unconditioned (unlearned) Begins with a reflex which is unconditioned (unlearned) A Neutral Stimulus is paired with a stimulus that evokes the reflex. A Neutral Stimulus is paired with a stimulus that evokes the reflex. Eventually the neutral stimulus alone will come to evoke the reflex. Eventually the neutral stimulus alone will come to evoke the reflex.

10. Pavlov’s Classic Experiment

11. Dog in Pavlov’s Apparatus

12. Pavlov took an untrained dog in a harness. Pavlov sounded a tone at certain intervals and every time the tone sounded he gave the dog food. The dog salivated when given the food. After several intervals, Pavlov would sound the tone and the dog would salivate even before the food was given to him. Pavlov took an untrained dog in a harness.

13. BEFORE CONDITIONING

14. During Conditioning

15. After Conditioning The process leading up to this is known as acquisition

16. Components of Classical Conditioning Unconditioned Stimulus (UCS) Unconditioned Stimulus (UCS) effective stimulus that unconditionally- automatically and naturally- triggers a response effective stimulus that unconditionally- automatically and naturally- triggers a response Food in mouth Food in mouth Unconditioned Response (UCR) Unconditioned Response (UCR) unlearned, naturally occurring automatic response to the unconditioned stimulus unlearned, naturally occurring automatic response to the unconditioned stimulus salivation when food is in the mouth salivation when food is in the mouth

17. Components of Classical Conditioning Conditioned Stimulus (CS) Conditioned Stimulus (CS) previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response Tone Tone Conditioned Response (CR) Conditioned Response (CR) learned response to a previously neutral conditioned stimulus learned response to a previously neutral conditioned stimulus Salivating to the tone Salivating to the tone

18. An experimenter sounds a tone just before delivering an air puff to your eye. After several repetitions, you blink to the tone alone.

19. Other Terms Pavlov Used To Describe Process of Conditioning 1. Acquisition 2. Extinction 3. Spontaneous Recovery 4. Generalization 5. Discrimination

20. Acquisition and Extinction Acquisition: the initial stage of learning, during which a response is established and gradually strengthened. When a neutral stimulus causes a conditioned response. When a neutral stimulus causes a conditioned response. Tone = Salivation Tone = Salivation Extinction: the diminishing of a conditioned response. When bell no longer makes dog salivate.

21. Spontaneous Recovery Spontaneous Recovery refers to the reappearance, after a rest period, of an extinguished conditioned response. Spontaneous Recovery refers to the reappearance, after a rest period, of an extinguished conditioned response.

22. Generalization vs. Discrimination Generalization: tendency for a stimuli similar to CS to evoke similar responses. Ex: doesn’t have to be same tone to make dog’s salivate…they generalize. Generalization: tendency for a stimuli similar to CS to evoke similar responses. Ex: doesn’t have to be same tone to make dog’s salivate…they generalize. Discrimination: the ability to distinguish between a CS and other stimuli that do not signal an UCS. Discrimination: the ability to distinguish between a CS and other stimuli that do not signal an UCS. Ex: dogs wouldn’t salivate to a whistle since it was too different from the tone. Ex: dogs wouldn’t salivate to a whistle since it was too different from the tone.

23. Effectiveness of Proper Conditioning Conditioning works best when a Conditioned Stimulus is presented before a Unconditioned Stimulus which is called forward conditioning Conditioning works best when a Conditioned Stimulus is presented before a Unconditioned Stimulus which is called forward conditioning Why do you think backwards conditioning (when Unconditioned stimulus is presented before conditioned stimulus) is usually ineffective? Why do you think backwards conditioning (when Unconditioned stimulus is presented before conditioned stimulus) is usually ineffective?

28. Criticism of Old School Behaviorists: They Ignore Cognition Studies proved that subjects attitudes did matter when attempting to create conditioned responses in them. Studies proved that subjects attitudes did matter when attempting to create conditioned responses in them. Ex: ½ told that being conditioned was wise, sensible, and intelligent while other half was told the reverse….positive instructions assisted conditioning while negative instructions undermined the process Ex: ½ told that being conditioned was wise, sensible, and intelligent while other half was told the reverse….positive instructions assisted conditioning while negative instructions undermined the process Drugs Drugs

29. Criticism of Old School Behaviorists: They Ignore Biological Predispositions Watson and Pavlov believed any animal (including humans) could be conditioned where ANY neutral stimulus paired with a unconditioned stimulus could easily produce a conditioned response.

31. Garcia’s Taste Aversion Studies Set up experiment with rats. Exposed them to sights, sounds, and tastes (CS) and later also gave them radiation or drugs that led to nausea and vomiting (UCR). Set up experiment with rats. Exposed them to sights, sounds, and tastes (CS) and later also gave them radiation or drugs that led to nausea and vomiting (UCR). Even if sickened hours later, rats avoided the particular flavor of water but did NOT develop aversions to the sights or sounds. Even if sickened hours later, rats avoided the particular flavor of water but did NOT develop aversions to the sights or sounds. Taste Aversion became known as the “Garcia Effect.” Taste Aversion became known as the “Garcia Effect.”

32. Importance of Taste Aversion Studies 1.) Violated behaviorists principle that any stimulus could serve as a CS. Flowers Flowers 2.) Shows that nature prepares the members of each species to learn those things crucial to their survival. 3.) Are exceptions to classical conditioning rules: UCS does not always have to follow CS immediately.

33. Some Real World Applications of Classical Conditioning 1. Crack cocaine users feel craving when they encounter cues associated with highs (people, places, etc). So drug and rehab counselors advise them to steer clear of these places and people…make new friends, move. 1.
