  • TIMING
    • CLASSICAL CONDITIONING
      • when a neutral stimulus is consistently paired with an unconditioned stimulus so that it eventually takes on the properties of this stimulus and is able to produce a conditioned response
        • classical conditioning involves involuntary behaviours
        • associating one thing with another thing
      • PAVLOV'S RESEARCH
        • dogs reacted with a stimulus that coincides with the presentation of food
          • concludes: animals learn through association
        • UCS = food
          • UCR = salivation
      • LITTLE ALBERT (WATSON + RAYNER)
        • initially 11 month old Albert showed no fear of white fluffy object such as rats + rabbits
          • researchers placed a white rat infront of Albert and as eh reached to stroke it a metal bar was banged loudly behind his head
            • overtime when Albert was then shown a white rat he would cry
              • this also happened when he was shown other white fluffy objects
                • fear response of white fluffy objects conditioned in Little Albert
              • fear response of white fluffy objects conditioned in Little Albert
        • helped support Pavlov's idea of classical conditioning
      • unconditioned stimulus causes a natural unconditioned response
        • a neutral stimulus is repeatedly paired with the unconditioned stimulus producing an unconditioned response
          • after conditioning, the neutral stimulus becomes the conditioned stimulus
            • the conditioned stimulus produces a conditioned response alone
              • CS = CR
            • NS --> CS
          • NS + UCS = UCR
        • UCS = UCR
    • EXTINCTION
      • CR doesn't become permanently established as response - CS can lose ability to produce CR
      • SPONTANEOUS RECOVERY
        • after extinction, if CS and UCS paired again, link made more quikly
        • STIMULUS GENERALISATION
          • Pavlov discovered that once an animal has been conditioned, they also respond to other stimuli similar to CS
    • if the time interval between NS and UCS is too great, conditioning doesn't occur
  • NS = bell
    • paired
      • UCS = food
        • UCR = salivation
      • bell (now CS) causes salivation (CR)
  • overtime when Albert was then shown a white rat he would cry
    • this also happened when he was shown other white fluffy objects
    • GORN - background music and participants picking a pen colour for a gift
      • extra examples
        • smelling a particular odour can bring back memories of a place or person
