The Forgetting Curve
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. A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger th…
What is the forgetting curve in psychology?
The Forgetting Curve is an influential memory model. It shows how learned information slips out of our memories over time – unless we take action to keep it there. The steepest drop in memory happens quickly after learning, so it's important to revisit the information you've learned sooner rather than later.
How can I reduce my forgetting curve?
Use "Spaced Learning" The most important discovery Ebbinghaus made was that, by reviewing new information at key moments on the Forgetting Curve, you can reduce the rate at which you forget it! This approach is often referred to as "spaced learning" or "distributive practice." [4] ( See figure 2, below.)
Why is it important to forget things quickly?
The ability to forget helps us prioritize, think better, make decisions, and be more creative. Normal forgetting, in balance with memory, gives us the mental flexibility to grasp abstract concepts from a morass of stored information, allowing us to see the forest through the trees.
What is Ebbinghaus’s forgetting curve?
Hermann Ebbinghaus’s forgetting curve explains that we are unable to hold newly introduced information for a long period of time. In fact, the founder of this concept discovered that we start to forget what we just acquired as information, quite literally, immediately after we’re exposed to it.
What is the impact of the forgetting curve and how can it be addressed?
Reinforce The Training Regularly Ebbinghaus discovered that information is easier to recall when it's built upon things you already know. Every time you reinforce the training, the rate of decline reduces. The testing effect says that by simply testing a person's memory, that memory will become stronger.
What the curve of forgetting shows us about memory?
In 1885, Hermann Ebbinghaus hypothesized a phenomenon he named “the forgetting curve”, which shows how information is lost over time if we don't revisit or establish connections to it.
Why is forgetting important for learning?
Forgetting strengthens learning New research suggests that forgetting is part of the process of learning and memorizing. It allows for new information. It's your brain's attempt to process new information— as soon as you learn something new, your brain process it and works to sort out its importance.
What is the forgetting curve and who discovered it?
Ebbinghaus' Forgetting Curve, more commonly known as the forgetting curve, is a memory model. It shows how we lose information over time if we don't try to retain it. Understanding how the curve works can help you to take action and prevent yourself from forgetting new skills or information.
How do you use a forgetting curve to study?
The good news is that there are a number of methods you can use in your courses to help your learners challenge the forgetting curve.Spaced learning. To thoroughly understand what is learned, there are two important elements to consider. ... Make it accessible. ... Keep it engaging. ... Create a learning culture. ... Make it relevant.
What is forgetting curve with example?
Have you ever taken a course and already the next day felt like you forgot most of what you've learned? That's not surprising. Unless we consciously do something to retain newly acquired information, we are likely to forget it in a matter of days.
How forgetting affect learning?
As we have emphasized, because forgetting can enable learning, conditions of instruction that create difficulties for the learner, even slowing the rate of apparent learning, often optimize long-term retention and transfer; whereas conditions of instruction that make performance improve rapidly often fail to support ...
What are the two main reasons for forgetting?
There are two simple answers to this question. First, the memory has disappeared - it is no longer available. Second, the memory is still stored in the memory system but, for some reason, it cannot be retrieved. These two answers summaries the main theories of forgetting developed by psychologists.
How does memory and forgetting affect students?
Because of the demands of the classroom, children with working memory issues frequently make poor academic progress: they forget important task information, disobey instructions, and fail to finish activities.
Is the forgetting curve a theory?
The issue was hypothesized by Hermann Ebbinghaus in 1885, which is why it's called Ebbinghaus forgetting curve. 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.
Is the forgetting curve true?
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.
How can we prevent forgetting?
AdvertisementInclude physical activity in your daily routine. Physical activity increases blood flow to your whole body, including your brain. ... Stay mentally active. ... Socialize regularly. ... Get organized. ... Sleep well. ... Eat a healthy diet. ... Manage chronic conditions.
What is the curve of forgetting quizlet?
The Forgetting Curve is a graph that shows the pattern of forgetting that occurs over time. It shows that forgetting is rapid soon after the original learning and the rate of memory loss gradually declines over time.
What did Ebbinghaus mean by the term forgetting curves?
Ebbinghaus is known for his 'forgetting curve' which suggests that people tend to continually halve their memory of newly learned knowledge in a matter of days or weeks unless they actively review the learned material [9].
What are 3 memory tasks used in measuring forgetting?
Researchers measure forgetting and retention in three different ways: recall, recognition, and relearning.
Who conducted the forgetting curve experiment?
Murre and Dros conducted a faithful replication of Ebbinghaus’ forgetting curve experiment, once again using a single subject.
What are reinforcement tools?
Reinforcement tools, such as Knowledge Guru, that are designed to help fight the forgetting curve and help learners remember things they need to know “cold”.
How to create a learning campaign?
At the most basic level, a learning campaign includes: 1 Cohesive branding and theme for the training initiative to generate excitement, motivation, and interest. 2 A clear value proposition for the learner, who should understand how the training connects to the bigger picture. 3 Timely reminders that are designed more like marketing messages than traditional emails from the L&D department. 4 Elements of “fun” incorporated throughout, whether that means a competition of some sort or the use of full-fledged learning games that connect to the campaign theme. 5 Online learning tools that are available on learners’ device of choice. 6 Reinforcement tools, such as Knowledge Guru, that are designed to help fight the forgetting curve and help learners remember things they need to know “cold”.
How long did Ebbinghaus study?
One of his studies lasted as long as seven months, and he repeated the same procedures virtually every day.
Why do trainers have to think beyond an event-based model?
Since the human brain is wired to forget without repeated exposure and practice, trainers have to think beyond an event-based model. This is why the concept of a learning campaign has been gaining in popularity.
Is the forgetting curve a sound concept?
The research (and our own experience) tells us that we can rely on it as a sound concept.
What is Hermann Ebbinghaus Forgetting Curve?
Hermann Ebbinghaus’s forgetting curve explains that we are unable to hold newly introduced information for a long period of time. In fact, the founder of this concept discovered that we start to forget what we just acquired as information, quite literally, immediately after we’re exposed to it. Unless we re-learn, note, practice, what’s new to us. We’ll completely remove it from our memories in a matter of days.
Why the Forgetting Curve Exist?
When it comes down to remembering new information, the most profitable habit you can cultivate is the habit of reexposing yourself to the thing you want to master.
Why Understanding the Forgetting Curve is Important?
What we have just learned is the following: The brain is hardwired to forget newly introduced information quickly because we’ll otherwise malfunction. We are constantly exposed to all kinds of new sensations. If the brain tries to store everything, we’ll literally choke. Since this is the case, we need to teach the brain that what we’re trying to learn is vital for our survival.
How to Overcome Forgetting and Strengthen Your Memory?
However, in the 21st century, your occupation requires you to constantly learn new things. You need to learn, hold, and practice new concepts so you can stay on top of your game.
How did Hermann Ebbinghaus come to this conclusion?
Hermann Ebbinghaus came to this conclusion after trying to memorize made words like “WID”, “ZOF and “KAF”. Then, he tested himself to see how many of these words he remembered. 2. The results were quite sad for humanity.
What are the questions to ask yourself?
Ask yourself these two questions: 1 What new did you learn? 2 What do you already know? 3 How the new info relates to what you know?
Why do people like how to videos?
Presentation: People love bite-sized how-to videos and guides for a simple reason: the brain loves these too. When something is easy to get, we actually get it. We feel like we are making progress and this positively contributes to our retention. So, if the person teaching us the material is able to properly present it, we’ll learn quicker. If the presentation is not engaging, our minds will wander.
What discovery did Ebbinghaus make?
The most important discovery Ebbinghaus made was that, by reviewing new information at key moments on the Forgetting Curve, you can reduce the rate at which you forget it!
What is Ebbinghaus's strategy?
Another strategy Ebbinghaus explored was "overlearning" – that is, putting in more than the usual amount of effort when you learn something. He found that doing this improved retention, and slowed the steep drop seen on the Forgetting Curve.
How did Ebbinghaus learn to remember?
Ebbinghaus experimented with his own ability to remember using a list of nonsense syllables, which he attempted to recall after different lengths of time. His experiences and results revealed a number of key aspects of memory:
What happens to retention after learning?
The biggest drop in retention happens soon after learning. This is reflected by the steep fall at the start of the Forgetting Curve (see figure 1). Without reviewing or reinforcing our learning, our ability to retain the information plummets. For example, you may leave a webinar or meeting with your head full of new facts and figures, only to find that you can remember very little of it just hours later.
How does sleep affect memory?
How you feel affects how well you remember. Ebbinghaus believed that physiological factors, such as stress and sleep, play a significant part in how well we retain information. Many people experience this as a vicious cycle – they feel stress, which makes it harder to remember, creating even more stress. There's also strong evidence to suggest that sleep can help our brains to sort and store information.
Why is it important to revisit information you've learned?
The steepest drop in memory happens quickly after learning, so it's important to revisit the information you've learned sooner rather than later. After that, regular reviews will help to reinforce it. But you can leave longer and longer gaps between these review sessions. This is known as "spaced learning."
Why is memory important?
Memory is important for our survival. Our brains are good at storing information that helps us to avoid physical or psychological harm. We are particularly good at remembering the things that we need to know – details that are of vital importance to our survival.
What would happen if you didn't forget the forgetting curve?
If it wasn’t for the forgetting curve, your learners could take an eLearning unit once, and it would stick in their brains first time.
What did Ebbinghaus discover?
Once he’d discovered the exponential decline of memory, Ebbinghaus could identify the factors that contribute to it. The level of retention depends on a couple of things:
Why is gameplay important in learning?
Adding elements of gameplay to the learning is a great way to keep the learner involved and they might even enjoy the training !
Why is it important to reinforce training?
Every time you reinforce the training, the rate of decline reduces. The testing effect says that by simply testing a person’s memory, that memory will become stronger. Staging frequent training interventions as part of a learning campaign helps solidify the information through active recall.
How to improve recall in a learning campaign?
Staging frequent training interventions as part of a learning campaign helps solidify the information through active recall. 2. Improve Clarity. Make the information easier to absorb in the first place. If you learn something from an essay or an article, it’s easier to forget the meaning or miss it entirely.
What is Epic Meaning in training?
An off-the-shelf learning resource won’t have the same impact as a custom-made one. In every piece of training you produce , never forget the core purpose of your organization, what we call the Epic Meaning. This works in 2 ways: the more relevant the training, the easier it is to recall, and the common focus continually encourages the behaviors that are important to your business.

We Were Doomed To Forget
We’ve all been there. It might have been for a class, a presentation, a training course, a promotion exam, or even a recital. You might be diligently keeping up with the current research in your field. And you committed to study, knowing how crucial increasing your knowledge base is inside this increasing information boom.
What Happened?
The culprit is our schooling. We were doomed from the beginning. Most of us (except for the lucky few who grew up among psychologists) learned to study linearly. We were taught a chapter or two, then were tested, then moved on to the next, over and over again.
The Problem: The Forgetting Curve
It all starts with Herman Ebbinghaus, considered the father of modern memory psychology. He memorized series of syllables and charted his recall through a period of days and weeks. What he found was simple, but revolutionary: his memory deteriorated surprisingly rapidly. The chart is called the forgetting curve.
But There Is Hope: The Review Efficiency Effect
Relearning the material likely did not take as long as learning it initially. If it didn’t, a full week of studying would not be enough for months of learning. And we passed the exam.
Enter: The Spacing Effect
The spacing effect in action. Note how after each review, the curve becomes shallower.
Say Hello to Your New Superpower: Spaced Repetition
Spaced repetition is simply reviewing learned material in a specific schedule. This is your new superpower.
Who was Hermann Ebbinghaus?
Hermann Ebbinghaus was a German psychologist and philosopher most well-known for his research on the forgetting curve and the spacing effect. His groundbreaking work on the forgetting curve was published in his paper “ Memory: A Contribution to Experimental Psychology ” in 1885.
What is the Ebbinghaus forgetting curve?
In conclusion, the Ebbinghaus forgetting curve helps us to better understand the forgetting patterns of our memories. It shows that we tend to forget things very quickly but also that the effect can be combated through various methods such as spaced repetition, active recall, and mnemonics.
How to calculate Ebbinghaus curve of forgetting?
The formula with which the Ebbinghaus curve of forgetting is calculated is the following: R = exp (-t/S), with R symbolizing memory retention, t symbolizing time, and S the relative strength of the memory.
What is the Ebbinghaus curve?
This curve shows an astoundingly steep memory decline in the first 24 hours, followed by a slower decline in the days after that. Initially proposed by Hermann Ebbinghaus in 1885, the existence of this forgetting curve has been confirmed countless times by researchers across different fields. Most recently in 2013, 2015, 2017, and 2021.
Why can't we store memories?
But, without using methods such as spaced repetition or active recall, your brain will not be able to store that memory for long due to memory trace decay and interference. A process more commonly known as “forgetting”. The rate and speed at which forgetting takes place are often visualized as a curve: the Ebbinghaus forgetting curve.
Why is it easier to remember when you review information?
When you review information in a given interval, it’s easier to remember because each successive review goes over the same concepts over and over. This process reduces forgetting, improves retention over time, and takes advantage of the Ebbinghaus forgetting curve.
How long does it take for memory to decay?
It is characterized by memories going through an initial stage of rapid memory decline within 24 hours, followed by a slower rate of memory decay over the long term. This curve of forgetting shows us that: Forgetting is a natural and necessary part of life.
Why is forgetting important?
The importance of forgetting is a relatively new concept for science. Until about a decade ago, normal forgetting—in contrast to ‘pathological’ forgetting that occurs in disease and with aging—was seen a passive process that served no useful purpose. Then studies began to coalesce from numerous fields revealing that there are separate molecular ‘nano-machines’ within neurons—one for memory and the other for forgetting. These findings point to an active mechanism within our brain that helps us clear out unnecessary pieces of information so that we can retain the most relevant for long-term storage.
How to prevent PTSD from burning?
One of the conclusions I came to in the book is that the best way to prevent not just PTSD but any painful memory from burning too hot is to stay social, seek friendship and love, and engage with life. Social interaction appears to quell the part of the brain that stores too many emotional memories, tamping down the fire. That’s one of the reasons the absence of human contact has been of such concern during the COVID-19 pandemic. Isolation and loneliness are associated with so many adverse consequences, from depression, high levels of anxiety, and suicide rates to reduced immune and cognitive functions.
Why is it important to remember?
In a world buzzing with information, it is essential to be able to turn down the noise and discard useless details, so they don’t interfere with access to new learning or ideas . Without our awareness, and particularly during sleep, the brain is constantly sorting out which memories to keep and which can be purged and forgotten. The ability to forget helps us prioritize, think better, make decisions, and be more creative. Normal forgetting, in balance with memory, gives us the mental flexibility to grasp abstract concepts from a morass of stored information, allowing us to see the forest through the trees.
What is the brain on fire?
Post-traumatic syndrome disorder is a condition in which traumatic or terrifying memories remain embedded in the mind like shrapnel, impeding the brain's natural recovery. It is disease of too much emotional memory—a “brain on fire” disorder, characteristic of other psychiatric conditions, such as obsessive-compulsive disorder, anxiety disorders, and phobias. In these disorders, key brain regions get flooded with signals that fire persistently. Conversely, “brain on ice” diseases, such as Alzheimer’s or Parkinson’s, are characterized by disrupted neuronal networks that gradually degrade over time.
What is photographic memory?
Photographic memory, a memory system in which snapshots never fade, is something of a myth, more fiction than science. There are people who have highly superior memories for certain things, but not all things. For example, in rare condition known as or hyperthymestic syndrome (also known as Highly Superior Autobiographical Memory or HSAM), people can remember a vast number of life experiences in vivid detail (including inconsequential events like a trip to Target), but they’re not necessarily gifted in recalling all information, such as phone numbers or where they put their keys. Why would anyone want a photographic memory, one that gives equal access to misery and to joy? Never to forget—to hold onto hurts, petty resentments, and traumatic experiences—would be a burden, and at worst, imprison us with pain.
Who is the professor of neurology at Columbia University?
In Forgetting, Dr. Small, the Boris and Rose Katz Professor of Neurology at Columbia, where he also holds appointments in psychiatry and radiology, translates the current science of memory to explain why forgetting benefits our cognitive and creative abilities, and even our personal and societal health.
The Ebbinghaus Forgetting Curve
Replication of The Forgetting Curve
- As I was preparing for the Reinforcement 101presentation Leanne Batchelder and I gave at the LTEN Annual Conference and in a subsequent webinar, I found a fascinating study where the authors attempted to replicate Ebbinghaus’ forgetting curve. Jaap M. J. Murre and Joeri Dros published the results of their work in July, 2015. You can read the full paperif you are interested, …
from Learning Events to Learning Campaigns
- Whether it takes place live or online, most training is designed event-based. Learners log on, take training on X, log off, and move on with their lives. In a more expensive example, learners fly in, participate in a training event while multitasking and checking their phones, fly home, and move on with their lives. What do we really expect them to remember if this is the only planned trainin…
