  1. Ivan Pavlov ClassicalConditioning

  2. Anything that causes some kind of reaction Stimulus

  3. A reaction to anything Response

  4. Unconditioned =Unconditioned Stimulus (UCS) Response (UCR) Food Salivates Neutral = Neutral Stimulus (NS) Response (NR) Bell No Reaction Step One

  5. Pairing Neutral + Unconditioned Stimulus (NS) Stimulus (UCS) Bell Food =Unconditioned Response (UCR) Salivates Step Two

  6. Conditioned = Conditioned Stimulus (CS) Response (CR) Bell Salivates Step Three

  7. In A Clockwork Orange, a brutal sociopath, a mass murderer, is strapped to a chair and forced to watch violent movies while he is injected with a drug that nauseates him. So he sits and gags and retches as he watches the movies. After hundreds of repetitions of this, he associates violence with nausea, and it limits his ability to be violent.

  8. Real-Life Examples of Classical Conditioning • Drug Tolerance -- Drug Overdose • drug users become increasingly less responsive • to the effects of the drug • tolerance is specific to specific environments (e.g. bedroom) • familiar environment becomes associated with a compensatory response (Physiology) • taking drug in unfamiliar environment leads to lack of tolerance  drug overdose
