Do mnemonic strategies really work?
Certainly. Mnemonic strategies work. However, for the most part they are strategies that require a great deal of practice to master, and it is arguable whether the tasks they are suited for are really worth such an effort. For example, to go to the trouble of using the method of loci simply to save yourself the effort of writing a shopping list is fairly pointless. However, if you have a professional need to remember lots of names, mastering the face-name association strategy is probably worth the (not inconsiderable) effort.
