Published in Memory.
A mnemonic (/nəˈmɒnɪk/,[1] the first “m” is not pronounced) device, or memory device, is any learning technique that aids information retention or retrieval (remembering) in the human memory.
Mnemonics make use of elaborative encoding, retrieval cues, and imagery as specific tools to encode any given information in a way that allows for efficient storage and retrieval. Mnemonics aid original information in becoming associated with something more accessible or meaningful—which, in turn, provides better retention of the information.
Commonly encountered mnemonics are often used for lists and in auditory form, such as short poems, acronyms, initialisms, or memorable phrases, but mnemonics can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous, or otherwise “relatable” information, rather than more abstract or impersonal forms of information.
