EDIT: after reading this post, make sure you ready my last comment.
After experimenting for a few days with the method of loci, visual linking and pegs, I think the method of loci is a poor choice for everyday use. The method of loci’s main advantages over using pegs or visual linking, is that you can jump to any room, so you don’t forget the rest of the elements if one item cannot be recalled, and that it minimizes interference, as long as rooms have enough contrast between each other.
Regarding losing the rest of the items if the chain is broken, for everyday use, people don’t even learn hundreds of items, they learn dozens at most( including med students). You can still forget items with the method of loci, it’s just that the damage is diminished; but the damage is diminished with shorter chains already, and you’ll have pretty good recall just with pegs or visual linking. Thus the advantage the method of loci has when using small chains, is negligible.
About the minimization of interference, very very few everyday things are prone to the interference the method of loci helps with. When you are memorizing decks of cards, the method of loci helps because this deck of cards is just like the previous and the next one; just a deck of cards. You could assign a number to your attempts, or a mental image if you like, but I doubt any mnemonist has tried that, as the method of loci works just fine for this. The reason the method of loci is not required for everyday things, is that if you are, for example, memorizing the list of symptoms caused by X condition, there’s only one list for that condition; another condition will have a different list, and two medical conditions will never have the same name.
Thus, people who are not aiming to compete, should be directed to linking and pegs, NOT the method of loci, because their time and effort is better spent on those techniques as they require much less resources, will give the same result, and more people will be enthusiastic about learning more about mnemonics.
Mixing the method of loci with pegs or visual linking for everyday use is not the answer either. It gives you the disadvantages of the method of loci, without any extra benefits.
There is one exception though: repeated temporary storage. The method of loci can then be used with pre-made rooms, that are overwritten, therefore reducing the cost of the method of loci to a single one time big cost, and the minimization of interference is actually useful in this case. This can even be useful for long lists when you cannot write or type down the information, as long as you remember to dump the information later to clear the palace for later use.
You might say that the problem is that I’m a beginner with mnemonics, but I hypothesize that the cost of creating new rooms using the method of loci for non-temporary storage will increase when you run out of easily accessible palaces to use; so the cost creating new rooms with the method of loci is NEVER equal or less than the cost of pegs or visual linking, at non-beginner levels. I’m not sure if the cost of pegs or visual linking recall is smaller than the method of loci though, because the method of loci givesa visual context, which might be more efficient than no context at all.
Opinions?
