Learning part 1

Learning part 1

1. classical conditioning

   • prewired to respond to certain stimulus
   • UCR: unconditioned response; response never needed to learn
   • UCS: stimuli that never needed to learn to respond to
   • CS - by pairing a neutral stimulus with a UCR, the natural stimuli will start to evoke the same response as the UCR (CR)
   • Ivan Pavlov
     • discovered classical conditioning through his work with dogs
   • Unlearn:
     • extinction trials
       • presenting the CS in the absence of the UCs
   • spontaneous recover
     • once a CS has been extinguished, the CR could always reoccur
     • extinguished response will be less intense and easier to extinguish
   • pairing
     • backwards
       • precent UCS then CS; very poor
     • simultaneous
       • present CS and UCS at the same time; ok
     • trace
       • present CS, then the UCS so they don't overlap; pretty good
     • delay
       • present CS, a short time later such that they overlap present the UCS; most effective
   • first order conditioning
     • pairing a neutral stimuli with a prewired response (UCS-UCR)
   • higher order conditioning
     • pairing a secondary CS with the first CS, anything other than first order
       • CS2 - CR2, CS3- CR3

2. relatively permanent change in behavior based on experiences
