The use of mental imagery and mnemonic devices as aids to information encoding and retrieval has been promoted by orators, teachers, and mnemonists for at least the past 2000 years (a comprehensive account of the history of mnemonic devices is given by Yates, 1966; a discussion of the nature of mnemonic devices is offered by Bellezza elsewhere in this volume; examples of mnemonic use in everyday contemporary life can be found in Furst, 1972 and Baddeley, 1976). Until recently, these claims were not widely accepted by the scientific commu nity because the evidence on which they were based was largely anecdotal. That is no longer the case. As the other chapters in this volume make clear, controlled experimental studies conducted over the past 20 years have substantiated the general claim that imagery and mnemonics facilitate the learning and recall of specific items of information and that these techniques can be taught to many types of people. |
