Explanation:

The Classic Conditioning was developed by Russian physiologist Ivan Pavlov. Pavlov experimented with a dog, a bell and a piece of meat. The physiologist noticed that when the dog saw the piece of meat, he salivated, which was called the unconditioned reflex. Classic conditioning also makes it possible to understand everyday things like the sound of an alarm clock, which for example. itself means nothing, but we relate that noise to the goal of waking up at a certain moment.

According to Pavlov, this is because our brains discriminate information, letting that information be specific to something specific. The opposite of discrimination is generalization.
