Try this letter memorization activity to employ a memory-enhancing strategy. So, if you met an interesting person at a party and you wanted to remember his phone number, you would naturally chunk it, and you could repeat the number over and over, which is the rehearsal strategy. Instead of trying to remember 5205550467, you remember the number as 52. Chunking is useful when trying to remember information like dates and phone numbers. Memorizing these facts is rehearsal.Īnother strategy is chunking: you organize information into manageable bits or chunks (Bodie, Powers, & Fitch-Hauser, 2006). You may recall that 6 x 6 = 36, 6 x 7 = 42, and 6 x 8 = 48. Think about how you learned your multiplication tables as a child. One strategy is rehearsal, or the conscious repetition of information to be remembered (Craik & Watkins, 1973). What are some everyday ways we can improve our memory, including recall? To help make sure information goes from short-term memory to long-term memory, you can use memory-enhancing strategies. In this section, we’ll look at some ways to help you remember better, and at some strategies for more effective studying. Most of us suffer from memory failures of one kind or another, and most of us would like to improve our memories so that we don’t forget where we put the car keys or, more importantly, the material we need to know for an exam. In this section, we will explain the general principles by which you can improve your own memory. He currently ranks second in the world, behind another German competitor, Johannes Mallow. Simon has been training his abilities for about 10 years as of this writing, and has risen to be in the top two of “memory athletes.” In 2012, he came in second place in the World Memory Championships (composed of 11 tasks), held in London. Twelve years earlier, before he started training his memory abilities, he had a digit span of 7, just like most of us. Instead, Simon has taught himself simple strategies for remembering that have greatly increased his capacity for remembering virtually any type of material-digits, words, faces and names, poetry, historical dates, and so on. So, does Simon Reinhard simply have a photographic memory? He does not. But in normal testing, no one gets 50 digits correct in a row, much less 240. That is why the first phone numbers were limited to 7 digits-psychologists determined that many errors occurred (costing the phone company money) when the number was increased to even 8 digits. After all, psychologists established many years ago that the normal memory span for adults is about 7 digits, with some of us able to recall a few more and others a few less (Miller, 1956). (No, he is not.) Second, Simon must have abilities more advanced than the rest of humankind. When most of us witness a performance like that of Simon Reinhard, we think one of two things: First, maybe he’s cheating somehow. His record in this task-called “forward digit span”-is 240 digits! In fact, Simon would have been happy to keep going. For a final trial, 50 digits appeared on the screen for 50 seconds, and again, Simon got them all right. Then came 30 digits, studied for 30 seconds once again, Simon didn’t misplace even a single digit. No one in the audience (mostly professors, graduate students, and undergraduate students) could recall the 20 digits perfectly. In the next phase, 20 digits appeared on the screen for 20 seconds.

After the series disappeared, Simon typed them into his computer. On the first round, a computer generated 10 random digits-6 1 9 4 8 5 6 3 7 1-on a screen for 10 seconds.

Memory is also a series of processes: how does that information get filed to begin with and how does it get retrieved when needed? In 2013, Simon Reinhard sat in front of 60 people in a room at Washington University, where he memorized an increasingly long series of digits. In some ways memory is like file drawers where you store mental information.
