SOCRATES is a mnemonic acronym used by emergency medical services, doctors, nurses and other health professionals to evaluate the nature of pain that a patient is experiencing. A mnemonic device is a mind memory and/or learning aid. Commonly, mnemonics are verbal-such as a very short poem or a special word used to help a person remember something-but may be visual, kinesthetic or auditory. Mnemonics rely on associations between easy-to-remember constructs which can be related back to the data that is to be remembered. This is based on the principle that the human mind much more easily remembers spatial, personal, surprising, sexual, humorous or otherwise meaningful information than arbitrary sequences.
