This tendency is described by the Ebbinghaus forgetting curve. Spaced learning is much more effective than massed learning where we try to cram all the information into a short period of time. In fact, the massed learning technique turns out to be hugely counterproductive. Spaced learning, on the contrary, enables us to better manage the information that is retained and increase our long-term productivity.
It leads to a better overall learning experience and ultimately allows us to reshape the forgetting curve. What is the Ebbinghaus Forgetting Curve? The Ebbinghaus forgetting curve is a graphical representation of the forgetting process. The curve demonstrates the declining rate at which information is lost if no particular effort is made to remember it. The forgetting curve was defined in by German psychologist Hermann Ebbinghaus in his book Memory: A Contribution to Experimental Psychology.
He was the first psychologist who systematically studied memory and learning. Ebbinghaus recorded his findings mathematically in an attempt to discover patterns of forgetting and memory retention. He plotted his results in a graph that we know today as the forgetting curve. Rate of forgetting Ebbinghaus found that the forgetting curve is exponential in nature.
It starts off very steep—the amount of retained knowledge drops dramatically soon after we acquire new information. In fact, most of the forgetting occurs within the first hour of learning. Without any additional work, we will quickly forget most of the content of a course, for instance. A week later, it will be as if the learning had never occurred at all.
Fortunately, there is a point at which the forgetting rate starts to decline at a slower pace. After a day or so, it usually levels off. This is when we can partially absorb essential details and remember them for some time. In other words, the day after taking a course, we will retain only a few details but we will be able to remember them for several more days. Still, this rate can be influenced to a certain extent by factors such as: prior knowledge of the subject the complexity of the material meaningfulness of the information the way the information is presented individual capability physiological factors including lack of sleep and hunger psychological factors like stress and anxiety Overcoming the Forgetting Curve While some aspects that contribute to the speed of forgetting cannot be changed, Ebbinghaus proposed the use of two methods when we purposefully acquire new skills or knowledge: mnemonic techniques and repetitions.
Implementing these strategies can help us overcome the forgetting curve. This strategy is based on creating associations with something that is easy to remember. For example, mnemonics use images, emotions, patterns, or rhymes like the alphabet song, to help us absorb the information more efficiently. Repetitions of information Ebbinghaus showed that repeating and reviewing the acquired knowledge helps strengthen our memory.
It is clear from the forgetting curve pattern that the initial repetition of the information should ideally occur within the first day of learning. But this is not enough. Each time we revisit the same material, we retain larger chunks of information.
As a result, the forgetting curve will start flattening out at a much higher level. That means we will forget at a slower pace. In order to retain knowledge and fully embed the learned material into our long-term memory, we have to periodically review the information. Research indicates that a minimum of three reviews is necessary for obtaining the best results. Ebbinghaus argued that each subsequent repetition increases the time needed before the next one.
This is called spaced learning. Spaced Learning For Ebbinghaus, overcoming the forgetting curve had more to it than just simple repetitions. Repetitions have to be spaced for optimal effect. Repeating new facts many times within an hour is not useful in overcoming the forgetting curve.
At the same time, if the information is repeated too infrequently, retention and recall will fail. In this case, we will have to start the learning process all over again. However, when the material is being repeated at strategically spaced intervals, the brain reconstructs the memory and strengthens it in the process.
These specific time intervals between multiple learning sessions are essential. They allow the brain to recover between repetitions and consolidate the learning. We can recall information and concepts better if we learn them in the course of several spread-out sessions. It is not necessary to review the information in exactly the same way in which the initial learning occurred.
Presenting the same concept in a slightly different form like a video or exercise is just as efficient in strengthening the memory and overcoming the forgetting curve. Related posts:.

Ebbinghaus Forgetting Curve
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. History The first study to hypothesize the forgetting curve was done in 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.
