Title: Forgetting
Content:  One of the first to study the mechanisms of forgetting was the German psychologist Hermann Ebbinghaus (1885). Using himself as the sole subject in his experiment, he memorized lists of three letter nonsense syllable words&mdash;two consonants and one vowel in the middle. He then measured his own capacity to relearn a given list of words after a variety of given time period. He found that forgetting occurs in a systematic manner, beginning rapidly and then leveling off. Although his methods were primitive, his basic premises have held true today and have been reaffirmed by more methodologically sound methods. The Ebbinghaus forgetting curve is the name of his results which he plotted out and made 2 conclusions. The first being 
Title: Forgetting
Content:  This method measures forgetting by the amount of training required to reach the previous level of performance. German psychologist Hermann Ebbinghaus (1885) used this method on himself. He memorized lists of nonsensical syllables until he could repeat the list two times without error. After a certain interval, he relearned the list and saw how long it would take him to do this task. If it took fewer times, then there had been less forgetting. His experiment was one of the first to study forgetting.
Title: Forgetting curve
Content:  From 1880 to 1885, Hermann Ebbinghaus ran a limited, incomplete study on himself and published his hypothesis in 1885 as Über das Gedächtnis (later translated into English as Memory: A Contribution to Experimental Psychology). Ebbinghaus studied the memorisation of nonsense syllables, such as "WID" and "ZOF" (CVCs or Consonant–Vowel–Consonant) by repeatedly testing himself after various time periods and recording the results. He plotted these results on a graph creating what is now known as the "forgetting curve". Ebbinghaus investigated the rate of forgetting, but not the effect of spaced repetition on the increase in retrievability of memories. Ebbinghaus's publication also included an equation to approximate his forgetting curve: represents time in minutes. Savings is defined as the relative amount of time saved on the second learning trial as a result of having had 
Title: Second-language attrition
Content:  Hermann Ebbinghaus contributed a lot to the research of the memory of the brain. He made the first empirical study concerning the function of the memory as to the storage and forgetting of information. His major finding was that the amount of learned knowledge depends on the amount of time invested. Further, the more time that is passing by, the more repetitions that are necessary. Resulting from the findings of Ebbinghaus, the first theory of forgetting was established, the decay theory. It says that if something new is learned, a memory trace is formed. This trace will decay, if not used in the course of time, and by decaying of this trace, forgetting occurs (Weltens 1987).

Content:  first. A savings of 100% would indicate that all items were still known from the first trial. A 75% savings would mean that relearning missed items required 25% as long as the original learning session (to learn all items). 'Savings' is thus, analogous to retention rate. In 2015, an attempt to replicate the forgetting curve with one study subject has shown the experimental results similar to Ebbinghaus' original data. Ebbinghaus' experiment contributed a lot to experimental psychology. He was the first to carry out a series of well-designed experiments on the subject of forgetting, and he was one of the first to choose artificial stimuli in the research of experimental psychology. Since his introduction of nonsense syllables, a large number of experiments in experimental psychology has been based on highly controlled artificial stimuli.
Title: Recall (memory)
Content:  loss occurred rapidly over the first few hours or days, but showed a more steady, gradual decline over subsequent days, weeks, and months. Furthermore, Ebbinghaus discovered that multiple learning, over-learning, and spacing study times increased retention of information. Ebbinghaus' research influenced much of the research conducted on memory and recall throughout the twentieth century. Frederic Bartlett was a prominent researcher in the field of memory during the mid-twentieth century. He was a British experimental psychologist who focused on the mistakes people made when recalling new information. One of his well-known works was Remembering: A Study in Experimental and Social Psychology, which he 
Title: Involuntary memory
Content:   Born in Bremen, Germany in 1850, Hermann Ebbinghaus is recognized as the first to apply the principles of experimental psychology to studying memory. He is especially well known for his introduction and application of nonsense syllables in studying memory, study of which led him to discover the forgetting curve and the spacing effect, two of his most well-known contributions to the field. Ebbinghaus was also the first to attempt a description of involuntary memory, stating that, "often, even after years, mental states once present in consciousness return to it with apparent spontaneity and without any act of the will; that 
Title: Hermann Ebbinghaus
Content:  In 1885, he published his groundbreaking Über das Gedächtnis ("On Memory", later translated to English as ''Memory. A Contribution to Experimental Psychology'') in which he described experiments he conducted on himself to describe the processes of learning and forgetting. Ebbinghaus made several findings that are still relevant and supported to this day. First, Ebbinghaus made a set of 2,300 three letter syllables to measure mental associations that helped him find that memory is orderly. Second, and arguably his most famous finding, was the forgetting curve. The forgetting curve describes the exponential loss of information that one has learned. The sharpest decline occurs in the 
Title: Amnesia
Content:  French psychologist Theodule-Armand Ribot was among the first scientists to study amnesia. He proposed Ribot's Law which states that there is a time gradient in retrograde amnesia. The law follows a logical progression of memory loss due to disease. First, a patient loses the recent memories, then personal memories, and finally intellectual memories. He implied that the most recent memories were lost first. Case studies have played a large role in the discovery of amnesia and the parts of the brain that were affected. The studies gave important insight into how amnesia affects the brain. The studies also gave scientists the resources into improving their knowledge about amnesia and insight into a cure or prevention. There are several extremely important case studies: Henry Molaison, R.B, and G.D.
Title: Forgetting
Content:  much of what we forget is lost soon after it is originally learned. The second being that the amount of forgetting eventually levels off. Around the same time Ebbinghaus developed the forgetting curve, psychologist Sigmund Freud theorized that people intentionally forgot things in order to push bad thoughts and feelings deep into their unconscious, a process he called "repression". There is debate as to whether (or how often) memory repression really occurs and mainstream psychology holds that true memory repression occurs only very rarely. One process model for memory was proposed by Richard Atkinson and Richard Shiffrin in the 1960s as a way to explain the operation of memory. This modal model of memory, also known as the
