  1. Classical Conditioning is
    a type of learning where a stimulus causes a response that was orginally cause by another stimulue
  2. Is classical conditioning voluntary or involuntary?
    involuntary
  3. Who was the Russian scientist that discovered the principle of classical conditioning and what was it?
    • Ivan Pavlov
    • dogs salivating right before food was placed in their mouths
  4. Classical conditioning can also be considered...
    stimulus generalization
  5. The conditioned stimulus (CS) (tone) come from
    the neutral stimulus (NS) (tone)
  6. An unconditioned stimulus (US) (meat powder) always elicits
    an unconditioned response (UR) (salivation)
  7. A conditioned stimulus (CS) (tone) always elicits a
    a conditioned response (CR) (salivation)
  8. In classical conditioning does the stimulus come before or after the response (behavior)?
    Before stimulus then response
  9. The behavior is _________ by the stimulus.
    ELICITED
  10. The response is like many other emotional responses...it is a
    reflect-like response
  11. The major difference between a CS (tone) and a UCS (meat powder) is that the UCS
    elicits the response of interest PRIOR to conditioning while CS does not
  12. How is classical conditioning used in advertising and how do it affect us? Give an example
    Advertisers pair their products with celebrities, attractive people etc. hoping that it will cause their products to make people have good feelings. Ex. Virginia Slims influences women smokers; Teenage mutant ninja turtles tv shows, they are put on sneakers and clothes making kids wanting to buy them
  13. How are phobias and classical conditioning related? Give an example
    • people's phobias are usually traced back to something terrible they experience when they were young. When they see the "something" later on it will trigger their fear automatically.
    • Ex. A girl upset her father when she was young and he hung her out the window of a 9th story building to punish her. She is now grown up and terrified of windows.
  14. A girl upset her father when she was young and he hung her out the
    window of a 9th story building to punish her. She is now grown up and
    terrified of windows. Explain what it the NS, CS, CR, UCS, and UCR
    • NS - window...there was no reaction before this incident
    • UCS - hanging out the window > UCR - fear of falling
    • CS - window > CR - fear of falling
  15. Aquisition is
    • the process in which a response was acquired through a pairing of the CS with and UCS
    • gradual approach
    • CS bell > UCS food = salivation
  16. Acquisition is forming a new response give an example
    • with dogs...
    • CS ring the bell > UCS give the dog food = dog salivates to bell b/c he thinks he will get food
    • over a number of trials the dogs salivation will level out b/c he knows that when the bell is rung he will get food so he salivates.
  17. Extiniction is the weakening of a conditioned response give an example
    • with dogs...
    • remove the UCS food and only ring the bell CS for a period of time the dog will eventually stops salivating to the sound of the bell b/c he is not getting any food.
    • ring the bell but no meat, ring the bell but no meat, etc and eventually the salivating will stop when the bell is rung.
  18. Spontaneous Recovery refers to the reappearance of a response that was was extinct after a period of nonexposure to the CS (the bell) give an example
    • in dogs...
    • the CS the bell will cause salivation in the dog after a period of not hearing it. The CS will not disappear all of a sudden.
    • When the dog hears the bell (CS) he thinks he will be getting food and starts salivating.
  19. Once a person or animal has learned, through classical conditioning, a response to a specific stimulus, they will respond in the same way to something that is similar to the original stimulus. What is this called? Give an example
    • Stimulus generalization
    • Little Albert > was conditioned to fear rats, he showed fear towards similar objects, all furry in nature.
  20. What is Operant Conditioning?
    learning in which responses are controlled by their consequences!
  21. Is operant conditioning voluntary or involuntary?
    involuntary
  22. Who discovered operant conditioning?
    B. F. Skinner
  23. Operant conditioning is all a matter of
    consequences
  24. According to Skinner, if a voluntary behavior leads to a good result the behavior is more likely to...
    be repeated
  25. Give an example of operant conditioning
    • If you speed >you get a speeding ticket
    • If you get a good grade on a test > your parents will give you $
  26. A stimulus is a _________ if it _________ the _________.
    • reinforcer
    • increases
    • behavior
  27. Acquisition and shaping in Operant conditioning is when... (give an example)
    • a reinforcer is given to shape to behavior of a desired response.
    • Teaching a dog to sit: Tell him to sit, when he doesn't push his back end down until he sits, then give him a treat. REPEAT this until he does it on his own. Still give him the treat for obeying.
  28. Extinction in operative conditioning is when...
    you take away the reinforcer and eventually the behavior disappears.
  29. A stimulus is a __________.
    reinforcer
  30. A reinforcer increases or decreases the behavior?
    increases
  31. Intermittent reinforcement is based on
    a fixed schedule of reinforcement
  32. A fixed ratio or fixed interval will produce ______ _______ to ________, b/c the person can predict when the next reward will be.
    lower resistance to extinction
  33. A variable ratio or variable interval will produce _______ _______ to ________, b/c the person cannot predict when the next reward will be given.
    higher resistance to extinction
  34. Both positive and negative reinforcers...
    increase behaviors
  35. Punishment does what with behaviors?
    decreases behaviors
  36. A positive reinforcer is anything _______ given to someone.
