Account of the life and accomplishments of herman ebbinghaus

Precise, scientific study was occurring in several psychological laboratories, but this was essentially limited to tests of physiological processes such as reaction time and sensory perception See our profiles of Wundt and J.

The methodology he developed for doing this brought the study of memory out of philosophy and into the realm of empirical science. Some of his innovations, such as the use of the nonsense syllable, are still valuable tools in 21st century learning and memory research Boneau, 1998; Wozniak, 1999.

Like his peers who used introspective methodology, Ebbinghaus used his own experiences as a source of data. To test his own memory, he first created 2300 nonsense syllables, each consisting of two consonants separated by a vowel e.

These syllables were necessary for a controlled experiment because they were presumably free of any previously learned associations.

He learned lists of these syllables until he had reached a pre-established criterion perfect recalland then recorded how many he was able to retain after specific time intervals.

He also noted how many trials were necessary for relearning after the syllables had been forgotten.

  • Shortly after Ebbinghaus left Berlin in 1893, Dilthey published a paper extolling the virtues of descriptive psychology, and condemning experimental psychology as boring, claiming that the mind was too complex, and that introspection was the desired method of studying the mind;
  • Discourse on the nature of psychology[ edit ] In addition to pioneering experimental psychology, Ebbinghaus was also a strong defender of this direction of the new science, as is illustrated by his public dispute with University of Berlin colleague, Wilhelm Dilthey.

His first set of trials took place over the course of one year 1879-1880 and he replicated the experiments three years later. After a successful replication, he published the results in Memory: A contribution to experimental psychology 1885 Eliasmith, 2004; Wozniak, 1999. His experiments demonstrated empirically that meaningless stimuli are more difficult to memorize than meaningful stimuli; that is, it is harder to memorize material that does not have significance or relevance to the learner.

Second, his data revealed that increasing the amount of material to be learned usually dramatically increases the amount of time it takes to learn it.

This is the learning curve. Third, he established that relearning is easier than initial learning, and that it takes longer to forget material after each subsequent re-learning. This insight was later confirmed by other researchers e.

  • This, too, continued to be a success, being re-released in eight different editions.
