This method is a mnemonic device adopted in ancient Roman and Greek rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero's De Oratore, and Quintilian's Institutio Oratoria).
[1] John O'Keefe and Lynn Nadel refer to:... "the method of loci", an imaginal technique known to the ancient Greeks and Romans and described by Yates (1966) in her book The Art of Memory as well as by Luria (1969).
In this technique the subject memorizes the layout of some building, or the arrangement of shops on a street, or any geographical entity which is composed of a number of discrete loci.
[4] Part of the competition requires committing to memory and recalling a sequence of digits, two-digit numbers, alphabetic letters, or playing cards.
[9] A study at the University of Maryland evaluated participants' ability to accurately recall two sets of familiar faces, using a traditional desktop, and with a head-mounted display.
The study found an 8.8% recall improvement in favor of the head-mounted display, in part due to participants being able to employ their vestibular and proprioceptive sensations.
[11][12] However, due to the strength of spatial memory, simply mentally placing objects in real or imagined locations without further elaboration can be effective for simple associations.
The purported advantage is to create towns and cities that each represent a topic or an area of study, thus offering an efficient filing of the information and an easy path for the regular review necessary for long-term memory storage.
In some cases it refers broadly to what is otherwise known as the art of memory, the origins of which are related, according to tradition, in the story of Simonides of Ceos and the collapsing banquet hall.
"[19] Skoyles and Sagan indicate that "an ancient technique of memorization called Method of Loci, by which memories are referenced directly onto spatial maps" originated with the story of Simonides.
[23] In other cases the designation is generally consistent, but more specific: "The Method of Loci is a Mnemonic Device involving the creation of a Visual Map of one's house.
"[24] This term can be misleading: the ancient principles and techniques of the art of memory, hastily glossed in some of the works, cited above, depended equally upon images and places.
In a classic study in cognitive neuroscience, O'Keefe and Nadel proposed "that the hippocampus is the core of a neural memory system providing an objective spatial framework within which the items and events of an organism's experience are located and interrelated."
The palace is built according to the rules discovered by Simonides of Ceos and elaborated by Cicero four hundred years later; it is airy, high-ceilinged, furnished with objects and tableaux that are vivid, striking, sometimes shocking and absurd, and often beautiful.
