Hermann Ebbinghaus (24 January 1850 – 26 February 1909) was a German psychologist who pioneered the experimental study of memory. Ebbinghaus discovered the forgetting curve and the spacing effect .
Hermann Ebbinghaus hypothesized that the speed of forgetting depends on a number of factors such as the difficulty of the learned material (e.g. how meaningful it is), its representation and other physiological factors such as stress and sleep. He further hypothesized that the basic forgetting rate differs little between individuals.
Hermann Ebbinghaus began the scientific study of human memory with this treatise On Memory in 1885. [2] Ebbinghaus experimented on himself by testing his own ability to memorize lists of randomly arranged syllables presented at a regular pace of 2.5 syllables per second.
The Ebbinghaus illusion or Titchener circles is an optical illusion of relative size perception. Named for its discoverer, the German psychologist Hermann Ebbinghaus (1850–1909), the illusion was popularized in the English-speaking world by Edward B. Titchener in a 1901 textbook of experimental psychology, hence its alternative name. [ 1 ]
The phenomenon was first identified by Hermann Ebbinghaus, and his detailed study of it was published in the 1885 book Über das Gedächtnis. Untersuchungen zur experimentellen Psychologie ( Memory: A Contribution to Experimental Psychology ), which suggests that active recall with increasing time intervals reduces the probability of forgetting ...
Serial-position effect is the tendency of a person to recall the first and last items in a series best, and the middle items worst. [1] The term was coined by Hermann Ebbinghaus through studies he performed on himself, and refers to the finding that recall accuracy varies as a function of an item's position within a study list.

Hermann Ebbinghaus (1850–1909) Encoding is still relatively new and unexplored but the origins of encoding date back to age old philosophers such as Aristotle and Plato. A major figure in the history of encoding is Hermann Ebbinghaus (1850–1909). Ebbinghaus was a pioneer in the field of memory research.
Hermann Ebbinghaus is generally credited with developing the first sentence completion test in 1897. [2] Ebbinghaus's sentence completion test was used as part of an intelligence test. [2] Simultaneously, Carl Jung's word association test may also have been a precursor to modern sentence completion tests. Moreover, in recent decades, sentence ...
