Ebbinghaus

Von Hartmann's work, on which Ebbinghaus based his doctorate, did suggest that higher mental processes were hidden from view, which may have spurred Ebbinghaus to attempt to prove otherwise.

After eliminating the meaning-laden syllables, Ebbinghaus ended up with 2,300 resultant syllables.

Amongst his counterarguments against Dilthey he mentioned that it is inevitable for psychology to do hypothetical work and that the kind of psychology that Dilthey was attacking was the one that existed before Ebbinghaus's "experimental revolution".

A typical representation of the forgetting curve The learning curve described by Ebbinghaus refers to how fast one learns information.

Charlotte Bühler echoed his words some forty years later, stating that people like Ebbinghaus "buried the old psychology in the 1890s".

Ebbinghaus also described the difference between involuntary and voluntary memory, the former occurring "with apparent spontaneity and without any act of the will" and the latter being brought "into consciousness by an exertion of the will".

Ebbinghaus illusion : the orange circle on the left appears smaller than that on the right, but they are in fact the same size.

Ebbinghaus is also largely credited with drafting the first standard research report.

Ebbinghaus made several findings that are still relevant and supported to this day.

Ebbinghaus, p. 189 Zermelo and Fraenkel had corresponded heavily in 1921; the axiom of replacement was a major topic of this exchange.

Ebbinghaus studied the memorisation of nonsense syllables, such as "WID" and "ZOF" by repeatedly testing himself after various time periods and recording the results.

Ebbinghaus would memorize a list of items until perfect recall and then would not access the list until he could no longer recall any of its items.

Following this short stint in the military, Ebbinghaus finished his dissertation on Eduard von Hartmann 's Philosophie des Unbewussten main ( Philosophy of the Unconscious ), and received his doctorate on August 16, 1873, when he was 23 years old.

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

German psychologist Hermann Ebbinghaus (1885) used this method on himself.

Hermann Ebbinghaus in Connections in the History and Systems of Psychology (3rd Edition ed., pp. 211-216).

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).

However, Ebbinghaus himself would probably describe himself as a psychologist considering that he fought to have psychology viewed as a separate discipline from philosophy.

However, more than a century before Ebbinghaus, Johann Andreas Segner invented the "Segner-wheel" to see the length of after-images by seeing how fast a wheel with a hot coal attached had to move for the red ember circle from the coal to appear complete.

In 1885, the same year that he published his monumental work, Memory: A Contribution to Experimental Psychology, Ebbinghaus, H. (1913).
