People with amnesia can even learn new facts and have their ability to recognize names55 and generate concepts56 improve in response to prior exposure, without having any memory of acquiring such knowledge. In fact, we are all in this position with respect to most of our semantic knowledge of the world. Do you remember learning the meaning of the word door? Probably not. How do you recognize it and bring its meaning to mind? You have no idea. These processes occur outside consciousness.57
