So you have worked hard to encode (via effortful processing) and store some important information for your upcoming final exam. How do you get that information back out of storage when you need it?<\/p>\r\n Retrieval<\/strong> is the act of bringing stored information back into conscious awareness. It\u2019s similar to reopening a file you previously saved on your computer: the information moves from long-term storage back into your active working space.<\/p>\r\n<\/section>\r\n Retrieval is essential for everyday functioning. Whether you\u2019re tying your shoes, driving a familiar route, or remembering how to complete a task at work, you rely on your ability to access information from long-term memory.<\/p>\r\n But here\u2019s the challenge: psychologists distinguish between information that is stored and information that is actually accessible.<\/p>\r\n Available<\/strong> information is the information that is stored in memory\u2014but precisely how much and what types are stored cannot be known. That is, all we can know is what information we can retrieve\u2014accessible <\/strong>information. The assumption is that accessible information represents only a tiny slice of the information available in our brains (Tulving and Pearlstone, 1966).<\/p>\r\n<\/section>\r\n Most of us have had the experience of trying to remember some fact or event, giving up, and then\u2014all of a sudden!\u2014it comes to us at a later time, even after we\u2019ve stopped trying to remember it. Similarly, we all know the experience of failing to recall a fact, but then, if we are given several choices (as in a multiple-choice test), we are easily able to recognize it.<\/p>\r\n There are three ways you can retrieve information from long-term memory storage: recall, recognition, and relearning.<\/p>\r\n Recall<\/strong> is what we most often think about when we talk about memory retrieval: it means you can access information without cues. For example, you would use recall for an essay test.<\/p>\r\n<\/section>\r\n Recognition<\/strong> happens when you identify information that you have previously learned after encountering it again. It involves a process of comparison. When you take a multiple-choice test, you are relying on recognition to help you choose the correct answer. Or let\u2019s say you graduated from high school 10 years ago, and you have returned to your hometown for your 10-year reunion. You may not be able to recall all of your classmates, but you recognize many of them based on their yearbook photos.<\/p>\r\n<\/section>\r\n The third form of retrieval is relearning<\/strong>, and it\u2019s just what it sounds like. It involves learning information that you previously learned.s; this is an example of relearning. Imagine that you took Spanish in high school, but after high school you did not have the opportunity to speak Spanish. Ten years later, you are asked by your company to work in their Mexico City office. In order to prepare yourself, you enroll in a Spanish course and are surprised at how quickly you are able to pick up the language after not speaking it for 10 years.<\/p>\r\n<\/section>\r\n What helps us pull information from memory? A key element is the presence of hints, or cues<\/em>, in our surroundings. Think of a song that brings back a rush of old memories the moment you hear it.<\/p>\r\n This phenomenon is governed by the encoding specificity principle<\/strong>: the manner in which we store information influences how we retrieve it. If a song is associated with a particular experience (like a memorable party), hearing it years later can trigger that memory. In an experiment, participants remembered words better when tested in the same location where they learned them, indicating that physical context can serve as a retrieval cue. Closely related to this concept are other types of situational-related memory cues, including:<\/p>\r\n But there's a catch about encoding specificity and dependent memories: if a cue is linked to too many memories, it loses its effectiveness. For instance, if you memorize a list of words and a single image of a penguin, the cue \"recall the image\" will help you remember the penguin. But if you mix 25 images into a 100-word list, the same cue won't be as useful. This phenomenon, known as the cue overload principle<\/strong>, shows the importance of distinctiveness in memory retrieval.<\/p>\r\n This leads to an interesting situation where recall can sometimes work better than recognition. This happens due to the encoding specificity principle. The cue \"George Bernard _____\" matches better with how you've stored the memory of the author compared to just the surname \"Shaw\". However, a common cue like \"William\" may not evoke \"Shakespeare\" due to the cue overload principle, since it's linked with many other famous Williams.<\/p>\r\n This phenomenon, called the recognition failure of recallable words<\/strong>, illustrates that the effectiveness of a cue depends on how the information was initially encoded. The most effective cues recreate the memory event. Sometimes, the actual memory target (like the surname \"Shaw\") is not the best cue. The success of recall depends on how the information was stored in the first place.<\/p>\r\n<\/div>\r\n<\/section>\r\n<\/section>\r\n<\/section>\r\n So you have worked hard to encode (via effortful processing) and store some important information for your upcoming final exam.
