    Okay. So once you have something stored in memory, you need to access that memory, so we need to retrieve it. So retrieval is the process of finding information that was once stored in our memory. That can be a fairly convoluted process, right? So how do we actually do that? So there’s a couple of ways that we’ve categorized here and one is called free recalls. This is retrieval of items with no constraints. The example is just list recall, so I’m asking you to remember or just -- no one’s even prompting you and you’re just listing things. I’m going to list, you know, five friends that I have and I’m just going to start saying that, versus cued recall, where items are associated with cues which assist in the recall So I can say things like, you know, name five of your friends. And you’re -- you’ve been cued to recall something and then you’re going in and getting, you know, five cities and you’re naming five cities. Recognition is identifying specific information for a set of information, for example a multiple choice question. So, say, you have a question and there’s an A, B, and C. I’m actually giving you specific information, making you go in to access that. So you have to recognize what are the areas of my memory that I need to access, get that information, and then when you’re looking at the multiple choice answers, you’re able to determine, you know, do I know the answer to that? I’m going to go check the files in my long-term memory, access it, and then answer the question. Okay? So, three types of recall. Now, relearning is when you’ve actually learnt something and then you have lost it, so, learning information that was once...
