Table of Contents Back in 1885, the German scientist Hermann Ebbinghaus made the first experimental studies in remembering and forgetting. What he discovered then still holds true today—that using the common method of memorizing, we forget forty per cent within twenty minutes and seventy-five per cent by the end of the week! Doesn't it stand to reason, then, that if you are going to bother to learn things once, you might just as well go to a little extra trouble and protect your investment of time? You can do this easily by repeating briefly what you have learned once a day for a week, and then once a week for a month. |
