(from P.A.Wozniak, Economics of Learning)
The third technique based on capitalizing on previously established memories is the graphic approach. In previous sections, declarative memories and emotion memories have been employed. Graphic approach makes use of the powerful visual processing capability of the human brain. It has been discovered long ago that visual memories are by far more stable than verbal memories. Indeed, the core of mnemonic techniques makes use of the visual processing capabilities to enhance memory retention. In graphic approach, graphs, illustrations, photographs or video clips are used instead of verbal descriptions. As it will be shown later, textual representation of knowledge does not preclude graphic approach; nevertheless, it is usually a graphic figure that makes the most straightforward solution.
