There are, in general, two types of memory books: scientific studies of memory or self improvement books.
One of my hopes for this blog is to bridge the gap between these two types of literature.
This means that I take seriously many popular books on memory improvement. Writers such as Harry Lorayne, Domonic O’Brien, and Tony Buzan are not scientists but they have made real contributions to memory improvement and should not be ignored. When Harry Lorayne wrote that “all knowledge and learning is based on connecting new things to things you already know” he was writing from his own experience and from the tradition of memory self-improvement. Yet, his observation is in keeping with the findings of modern memory science. More over, Lorayne and others have demonstrated remarkable feats of memory that demand explanation and are worthy of scientific investigation. For example, Domonic O’Brien, once memorized 316 random digits in five minutes. His ability to memorize cards is so good that he has been banned from many casinos.
My only criticism of these popular books is their almost exclusive reliance on mnemonics. Now, mnemonics are a powerful technique that I use all the time, and I will certainly feature them in this blog. However, there are other techniques that are less well known, particularly spaced repetition learning that help us remember many things that are not easily handled by mnemonics. You can try out spaced repetition learning at Memrise.
