The Ebbinghaus Forgetting Curve
The Ebbinghaus forgetting curve is a graph illustrating the principle of storage decay, which shows how memory for new information declines over time. The graph plots 'Retention (%)' on the y-axis against 'Elapsed time since learning' on the x-axis. It demonstrates a rapid initial loss of memory, which then slows and levels out. According to the curve, retention is 100% immediately after learning but drops to approximately 55% after 20 minutes and 40% after an hour. The decline continues to about 30% retention after 24 hours, eventually stabilizing at around 10% after 31 days.

The Ebbinghaus Forgetting Curve
Example of Transience: Forgetting a Book's Plot
Last year, a student thoroughly studied the details of a specific historical war for a final exam, learning key dates, battle locations, and commander names. Now, when asked about it, the student can only recall the general outcome and a few famous figures, but the specific, detailed information has become inaccessible. Which of the following best explains this common memory failure?
A student crams for a final exam in a subject they are not interested in. They perform well on the test but find that six months later, they can barely remember any of the specific facts or formulas they memorized. They only have a vague recollection of the general topics covered. Which of the following principles of memory best explains this experience?

Learn After
Four students are tasked with learning a list of 50 new historical dates. Student A studies the list intensively for three hours on a single day, a week before the final test. Student B studies the list for 30 minutes each day for the six days leading up to the test. Student C reviews the list for 10 minutes right after the initial lesson and then doesn't study again. Student D crams by studying the list for three hours the night before the test. Based on the established principles of how memory for new information declines over time, which student's study method is most likely to result in the highest retention of the dates one month after the test?
