One subject spent 70 hours learning lists and relearning them after 20 min, 1 hour, 9 hours, 1 day, 2 days, or 31 days. The results are similar to Ebbinghaus' original data. We analyze the effects of serial position on forgetting and investigate what mathematical equations present a good fit to the Ebbinghaus forgetting curve and its replications. We conclude that the Ebbinghaus forgetting curve has indeed been replicated and that it is not completely smooth but most probably shows a jump upwards starting at the 24 hour data point.

Ebbinghaus forgetting curve describes the decrease in ability of the brain to retain memory over time. The theory is that humans start losing the memory of learned knowledge over time, in a matter of days or weeks, unless the learned knowledge is consciously reviewed time and again. A related concept to the forgetting curve is strength of memory , which states that the time period up to which a person can recall any memory is based on the strength of the particular memory.
The first study to hypothesize the forgetting curve was done in Mathematically, the formula that can describe the phenomenon is. R refers to memory retention, S refers to relative strength of memory and t refers to time. Hermann published is first study about the forgetting curve in German, which was later translated to be called Memory: A contribution to Experimental Psychology.
Ebbinghaus conducted a series of tests on himself, which included memorization and forgetting of meaningless three letter words. The results thus obtained were plotted in a graph, which is now referred to as the forgetting curve.
Ebbinghaus found the forgetting curve to be exponential in nature. After which, the declination of memory retention slows down again. In simple words, forgetting curve is exponential because memory loss is rapid and huge within the first few days of learning. But, the rate of memory loss decreases and the rate of much forgetting are much slower from then on.
Ebbinghaus also discovered another phenomenon called overlearning during his study on forgetting curve.
The basic idea is that if you practiced something more than what is usually required to memorize it, the effect of overlearning takes place. This means that the information is now stored much more strongly and thus the effects of forgetting curve for overlearned information is shallower.
Herman Ebbinghaus pointed out that different in memory performance between two different individuals can be explained by mnemonic representation skills. Ebbinghaus hypothesized that difference in memory strength between individuals could be somewhat triumphed over by simple training in mnemonic techniques. Two of the methods he asserted to be among the best ways to increase strength of memory are:. He believed that each repetition in learning leads to increase in the interval for when the next repetition is required.
It was later discovered that higher original learning also lead to slower loss in memory. For instance , taking time to repeat information every day during exams decreases the effects of the forgetting curve. According to research, information should be repeated within the first 24 hours of learning to reduce the rate of memory loss. Note: Not all memories follow the forgetting curve as there could be various other factors in play, such as noise and other environmental factors.
Because of their influence on what information is remembered, not all memories are affected by detrimental effects of interference. The greatest debate regarding the forgetting curve is about the shape of the forgetting curve when it comes to more significant notable events. Others, however, have made an argument that recollections of events recorded in different years have shown sizeable amount of variations.

5 Ways to Challenge the Forgetting Curve
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. The stronger the memory, the longer period of time that a person is able to recall it. A typical graph of the forgetting curve purports to show that humans tend to halve their memory of newly learned knowledge in a matter of days or weeks unless they consciously review the learned material. The forgetting curve supports one of the seven kinds of memory failures: transience, which is the process of forgetting that occurs with the passage of time.
Ebbinghaus forgetting curve
How often have you taken an online course and remembered every piece of information you consumed immediately afterward? Probably never. For learning and development professionals, this presents an obvious challenge. To tackle this challenge you need to understand what the forgetting curve is, and more importantly, the impactful tactics you can use to overcome it. If you lost that piece of paper, would you remember the phone number an hour later?
You probably won’t remember this, but the “forgetting curve” theory explains why learning is hard
