    Anything in the enviorment to which an organism might react.
  3. Response
    any behavior resulting from a stimulus
  4. habituation
    • decrease in reaction to a repeated stimulus
    • -simplest form of learning
  5. Classical conditioning
    A new stimulus begins to elict the same response as another stimuli when they occur together.
  6. Pairing
    learning occurs when the CS is paired reliably with the UCS
  7. Extinction
    decrease or dissaperance of the CS when it is no longer paired with with UCS. Doesnt mean forgotten.
  8. Spontaneous Recovery
    the return of the CS after a delay
  9. Stimulus gerneralization
    When stimuli similiar to the CS elicit a CR
  10. Stimulus Discrimination
    When a stimuli similiar to the CS does not elecit a CR
  11. Operant conditioning
    acquiring behaviors as a result of the outcome or consquence of those behaviors ( reward and punishment)
  12. Thorndike's law of effect

    Reinforcement after a fixed number of responses (money in soda machine)
  19. Fixed interval
    reinforcement after a fixed amount of time (baking cookies)
  20. variable ration
    Reinforcement after a varying number of responses (gambling)
