The document reviews two examples of classical conditioning: 1) A girl who felt happy whenever she found strawberries in a brown bag her mother brought home every Monday. As an adult, she now feels happy when she sees a brown bag on a Monday. 2) A boy whose brother glued his goggles as a prank. He panicked when he couldn't remove them and ripped them off, removing his eyebrows. He is now afraid of goggles and similar items.
