At a similar rate, with review after one day only one-half of the material that was reviewed will be lost. If reviewed again on day two, the amount lost is again divided by two. If reviewed six times in a thirty-two day period, the about retained will be more than ninety-eight percent and the amount lost will only be about two per-cent in the next thirty-two days versus fifty per-cent in one day. * * * * * Memorization Three common ways of remembering are: repetition, association, and exaggeration. [4] An similar skill is outlining, and samples of various outlining styles can be found in Appendix 1. Repetition is the key to long term memory. Physiologically, when brain cells are activated by the memory process, the nerve cell coating, known as the glial sheath, increases in thickness and becomes thicker and thicker with each repetition, strengthening the electrical pathway in brain that constitutes memory. In addition, when associations between parts of a thing remembered are formed, the nerve cell body sends out axon runners to other associated memory cells. These axon runners from one cell connect through synapses to dendrite runners on other cells. As the axon-dendrite pathway is used repetitiously, the surrounding glial cells become larger and more tightly wrapped around the electrically conductive axon-dendrite pathways, thereby transforming the memory from a short-term memory to a long-term memory.[5] Memories of similar objects reside in nearby regions of the brain, while memories of exotic or exaggerated objects are farther away. By forming memories with creative and unusual associations, many more pathways are established, much like a spider weaving a bigger and bigger web, in which each part leads to the center by many interconnected pathways. Memory links are also established when a variety of sensations and muscular activity are engaged. Indeed, some people seem to be more proficient at learning by either seeing, hearing or writing, but no one method can provide the more numerous pathways provided by all three in combination. Memory is enhanced not only by repetition, but also by association and exaggeration of certain features of the object. Many memories are recalled as series of objects. For instance, a memory device to remember four common logical fallacies is a picture of the Earth, with the green continents and blue oceans, viewed from outer space with a flight of white geese circling around it. This image is used to recall the statement "geese circle every continent." The first letters of that statement (gcec) stand for the logic fallacies of generalization, circularities, either/or, and cause and effect. (These fallacies are discussed in detail in a later chapter.)
