He noticed that memory for learned material decreased over time (see also forgetting curve).

The forgetting curve describes the exponential loss of information that one has learned.

With this data, he traced learning and forgetting curves.

First, arguably his most famous finding, the forgetting curve.

He plotted these results on a graph creating what is now known as the "forgetting curve".

He was known for the discovery of the learning curve and the forgetting curve.

The forgetting curve hypothesizes the decline of memory retention in time.

According to these findings the forgetting curve begins with an initial plateau, a period where the language competence is not affected at all.

The Ebbinghaus forgetting curve is the name of his results which he plotted out and made 2 conclusions.

Like the forgetting curve, the learning curve is exponential.

The "forgetting curve" helps to explain why we so often remember nothing shortly after cramming intensely for an exam.

From this he discovered the Forgetting curve and the Spacing effect, two of his most well-known contributions.

The latency function relates to the forgetting curve.

From his discovery regarding the "forgetting curve", Ebbinghaus came up with the effects of "overlearning".

The recall or forgetting curve illustrate that each item in a cluster typically requires about the same amount of time to recall.

"What you really need is a cultural shift, what I call a 'forgetting curve,' instead of a 'learning curve.'

The forgetting curve orientates on the typical forgetting curve by Ebbinghaus.

Using information immediately after receiving it enhances information retention and lessens the forgetting curve (the rate at which we no longer retain information in our memory).

This effect is shown in the forgetting curve developed by Hermann Ebbinghaus, who established the hypothesis of the exponential nature of forgetting.

Since then, numerous studies have established that not only are both meaningful and nonsense "words" easily forgotten, but that both their forgetting curves are exponential with time.

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.

Some of the techniques have existed since ancient times (e.g. Mnemonics) whilst others are a result of more recent scientific research (e.g. Forgetting Curves).

A Flashbulb memory is said to be less accurate and less permanent than photographic memories, but its forgetting curve is less affected by time in comparing to other types of memories.

However, unknown remains if the curve that follows this plateau might be exactly like the "normal" forgetting curve of language learners with a lower proficiency level (Weltens & Cohen 1989: 130).

Most people have no memory prior to three years of age, and few memories between three to six years of age, as verified by analysis of the forgetting curve in adults recalling childhood memories.
