The Forgetting Curve

The Forgetting Curve is a concept developed by German psychologist Hermann Ebbinghaus in the late 19th century to describe how memory retention declines over time. Ebbinghaus conducted experiments to measure how quickly we forget information after learning it, and his findings revealed a predictable pattern.

Key Points of the Forgetting Curve:

Rapid Decline in Retention:

After we learn something new, our ability to recall the information decreases rapidly within the first 24 hours. Ebbinghaus found that we forget about 50-80% of newly learned information within this period.

Exponential Nature: 

The rate of forgetting is not linear; instead, it follows an exponential decay. This means that after the initial rapid loss, the rate of forgetting slows down over time.

Influencing Factors: 

The speed at which we forget depends on several factors, including the complexity of the material, the way it was learned, the individual's prior knowledge, and the context in which it was learned.

Combating the Forgetting Curve with Spaced Repetition:

One of the most effective ways to counteract the forgetting curve is through spaced repetition. By reviewing information at strategically spaced intervals, we can reinforce our memory and significantly slow down the forgetting process. Each review resets the curve, making the decline in retention less steep with each repetition.

Practical Implications:

Understanding the forgetting curve is crucial for effective study habits. Instead of cramming all the information in one session, it's better to review material multiple times over a longer period. This technique helps to transfer knowledge from short-term to long-term memory, improving retention and recall.

By applying spaced repetition and acknowledging the natural tendency to forget, students can optimise their learning and retain information more effectively, ultimately enhancing their academic performance.
