What graphical representation illustrates the amount of forgetting over time after learning?

The forgetting curve is a well-established graphical representation that shows how information is lost over time when there is no attempt to retain it. This concept was introduced by Hermann Ebbinghaus through his experiments on memory, where he demonstrated that after learning, the rate of forgetting is initially rapid but then levels off over time. The curve typically reveals that most forgetting occurs shortly after the initial learning phase, which emphasizes the importance of review or practice to enhance memory retention.

In contrast, the retention curve focuses on the amount of information retained over time after a specific learning period, while the learning curve depicts the process of acquiring new knowledge or skills over time. A memory enhancement chart would not specifically illustrate forgetting; instead, it might focus on strategies or techniques to improve memory. Thus, the forgetting curve aptly illustrates the phenomenon of forgetting as time progresses after learning.
