What is Hermann Ebbinghaus?
[[File:Ebbinghaus2.jpg|thumb|Hermann Ebbinghaus]] '''Hermann Ebbinghaus''' (24 January 1850 – 26 February 1909) was a [[Germany|German]] [[psychologist]]. Today, he is mostly known for his work regarding [[learning]] and forgetting. He was the first to do [[Experiment|experiments]] to explore how [[memory]] works. He first described the [[forgetting curve]], the [[learning curve]] and the [[spacing effect]]. The [[Ebbinghaus illusion]], which is named after him is related to the [[perception]], not memory. His son was the philosopher [[Julius Ebbinghaus]]. In 1896, he did a test on children in school: The pupils had to complete sentences, and their teacher had to rate each pupil, if the pupil was in the lowest, the middle or the highest third of all the people in the class. Ebbinghaus saw a relationship between the teacher's rating, and the result of the pupil, but he could not give a [[correlation]] (because he was lacking the tools to do so). This was possibly the first test of verbal [[intelligence]] in a group. Many of his experimental methods to rate memory performance are still in use. Ebbinghaus died of [[pneumonia]], when he was 59 years old. {{bio-stub}} {{DEFAULTSORT:Ebbinghaus, Hermann}} [[Category:1850 births]] [[Category:1909 deaths]] [[Category:German psychologists]] [[Category:Deaths from pneumonia]]
