Classical Conditioning is a way that animals, including humans, learn to associate two things together. It's like when you hear a bell ring every time you get food. At first, the bell doesn't mean much to you. But if it keeps happening, eventually you start to link the bell with food. So, even if there's no food around, just hearing the bell can make you feel hungry. That's classical conditioning! It's about learning to connect two things in your mind.
