Human memory retention and its application to language learning

摘要

This invention deals with human memory retention and its application to language learning or any training process that requires memorization of the old information learned in the early time. A memory retention function with a form of R=A.t^(d-D) is used, where R is the percentage (%) of memory retention after a time span t for the content learned earlier, and d is the fractal dimension of the active dendritic neurons in human brain cell, that participate in the learning process, and D (equal either 2 or 3) is a physical dimension. The implication of this human memory retention scheme is that by repeated reviewing, more dendritic neurons become activated (i.e., cross-linked with nearby neurons having certain degree of prior knowledge) resulting in a larger d. This invention proposes a method to estimate the fractal dimension d from the memory activities for each user in language learning process, which provides a way to predict when next memory rehearsal (repetition) is needed before the earlier learned-information are likely forgotten.
