Here is a case of simple associative learning (stimulus to stimulus, with no specific response) that I think will give you a smile for your weekend. Imagine a dog (one of those little terriers about 8 inches tall – something like this one being placed for the first time in a yard with a two inch tall wooden fence. What do you think is the first thing he would do? Perhaps after briefly exploring the local smells, he would wander outside the fence. Walking over a two inch fence would not even be noticed, let alone a deterrent.
Associative learning is the process by which an association between two stimuli or a behavior and a stimulus is learned.
