Many systems of mnemonics are described in the literature. All their diversity is divided into two main types:
- Classical mnemonics, originating from the book “Ad Herennium” (86-82 BC);
- Pedagogical mnemonics, formulated by Peter Ramus (the end of XVI century, England).
Classical mnemonics has always based on the mechanisms of visual (imaginative) thinking, while pedagogical mnemonics does not use images and focuses on speech thinking. Typical techniques of pedagogical mnemonics include breaking the memorized material into small parts, followed by intensive repetition (or rote learning), then composing phrases by letters that are obtained from memorized numerical information. Then the search for patterns in the stored information begins, it is classified and systematized, and structural diagrams are compiled. A well-known phrase: “every hunter wants to know where pheasants is” refers to pedagogical mnemonics.
