AP PSYCHOLOGY

Detailed explanation-1: -In 1885, Hermann Ebbinghaus, a German psychologist who pioneered studies of memory and learning, developed his thesis of the exponential nature of forgetting and the speed with which information is lost when there is no attempt to retain it.

Detailed explanation-2: -Hermann Ebbinghaus (24 January 1850 – 26 February 1909) was a German psychologist who pioneered the experimental study of memory, and is known for his discovery of the forgetting curve and the spacing effect. He was also the first person to describe the learning curve.

Detailed explanation-3: -Memory experiments Ebbinghaus started by memorizing lists of words and testing how many he could recall. To avoid the use of association, he then created 2, 300 “nonsense syllables”, all three letters long and using the standard word format of consonant-vowel-consonant: for example, “ZUC” and “QAX”.

Detailed explanation-4: -Ecphory describes the memory retrieval process, and Semon argued that ecphory reflects the unique interplay between cues and stored memory traces at retrieval. He also coined the term engram’ to refer to such memory traces as biological entities; this may be considered his better-known contribution to the field5.

Detailed explanation-5: -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.
