Memory is the way in which a past experience affects how the mind will function in the present. There are two layers of memory: explicit and implicit. There are two key attributes of implicit memory that are critical to understand. First, implicit memories are created whether you are paying attention or not. In other words, when you were a child, you recorded tons of information about your environment without trying to. It just happened. Because that's how the brain works. Second, when you recall something that is stored in implicit memory, you do not have the sensation of recall. You don't have that sense in your body of "I'm thinking back in time and remembering something." When we leave home and set out into the world, we carry within us a storehouse of implicit memories. And those implicit memories tell us what to expect around every bend.
