ELI5: Explain Like I'm 5

Object association

Okay, imagine you have a toy car and a toy garage. When you put the car in the garage, they become associated with each other. They go together like mac and cheese or peanut butter and jelly. When you take the car out of the garage, they are no longer associated. Object association is like that, but with things that are not toys. It's when two or more things are linked together in some way. For example, a key and a lock are associated because the key opens the lock. Or, your toothbrush and toothpaste are associated because you use them together to brush your teeth. Object association is all around us and helps us make sense of the things we interact with every day.
