At first, Ebbinghaus randomly made some English spelling words (which didn't actually exist) to test the forgetting rule. He regularly recalled the words he remembered, recorded the numbers of "memory" and "forgetting", and finally formed the forgetting curve that we all know.
But unfortunately, there is still much controversy about this forgetting curve. The main reason is that when Ebbinghaus did the experiment, the sample data was not comprehensive. He took the "meaningless" word memory as the sample of the experiment, but this sample data hardly existed in actual operation.
And everyone's memory has great individual differences. Even if there are enough sample data, the reference value of almost all experimental data will be questioned, because the subjects may not know whether they have "independently memorized" the memory content.
Maybe, you will find. When we remember something interesting, we will remember it very easily. For example, it is easy for us to remember the phone number of our lover or family, but it is difficult for us to remember the phone number of strangers. Or your favorite star, team, or even subject knowledge.
All these contents will break the model of Ebbinghaus curve, and it seems that the theory of Ebbinghaus curve will fail in these cases.
Even though many people are skeptical or scoff at Ebbinghaus curve, it is undeniable that it has become a recognized model in the field of memory.
Perhaps, you will be skeptical about this model, but inevitably, you can't find any other model that can better explain the law of forgetting except Ebbinghaus curve.
Just like we can look at the speedometer when driving. The principle of speedometer is calculated by on-board computer according to the wheel circumference and wheel speed, but we all know that the wheel circumference will be affected by tire pressure and vehicle weight, so it is not reliable strictly.
However, we can't find the second way, which is cheaper and more reliable than the current scheme.
This is why when we mention memory, we will mention Ebbinghaus curve.
Because, besides, we have no other data to explain the law between "memory" and "forgetting" more accurately.
Because everyone's interests and personal situation are different, the degree of memory is also very different.
Happily, in the field of memory, there are many memory methods that can help us remember. The most famous one is "Memory Palace". This method mainly uses homophonic method, substitution method, serial method, coding method, stake method and key method to memorize the contents to be memorized by sound, logic and image.
However, even if we remember in this way, we still only finish short-term memory. If you want to form a long-term memory, you still need to review the memory content regularly. At this time we refer to Ebbinghaus curve model.
In fact, whether Ebbinghaus curve is scientific or not is not important to us. Most importantly, it guides the law between "memory" and "forgetting" and points out the direction for our long-term memory.
For everyone, due to external or internal factors, everyone's Ebbinghaus curve will eventually form, but it doesn't really matter, because you also have your own Ebbinghaus curve. If you look carefully, you should not find a unique Ebbinghaus curve in every field of your knowledge.
