Definition: forgetting mean failure at anytime to recall an experience, when attempting to do, or to perform an action previously learned.
Many Psychologists are interest in process by which forgetting take place, the researcher who found this field was Hermann ebbinghaus (1850-1909), he invented a lot of claptrap syllable in order to access a pure learning, one is the rate at which we forget. He used little or no meaning material because he knew learning new information is subjective by what we already know, therefore he decided to create a learning situation that were free of past knowledge.
The way we forget stuff is highly predictable, when we gain some new information or knowledge, the forgetting take place right away. Ebbinghaus found that he forgot significant amount of the information within 20minutes, almost half of the useless information was forget ton in an hour, and almost two third of the information was forgotten by the end of the day. In 1973 Yarn ell and lynch took this experiment further by experimenting football player immediately after the injury and after twenty minutes of injury. They discovered that immediately after the injury the player remembered what strategy they and their team player were using but after twenty minutes they could not remember anything about the strategy; it completely disappeared from their memory. This may be because of damage also known as amnesia.
Psychologist Hermann Ebbinghaus was also one of the first scientists to study forgetting. He performed experiments in which he took himself as a subject to test his memory, by using three letter nonsense syllabuses. He used different words to avoid similarities of words that he went through in past. And to this he tested his own memory for period ranging from 20minutes to 31days. His results plotted a curve, also known as ebbinghaus forgetting curve, which showed the relationship between forgetting and time. Due to this he found out
