Question
Hermann Ebbinghaus’s experiment
✓
Answer
- The pioneer of experiments on forgetting was Hermann Ebbinghaus.
- He created several lists of nonsense syllables and learned them. A nonsense syllable is a set of three alphabets where two on both the sides are consonants and the middle one is a vowel, e.g. NOM, GEX.
- He checked his own recall at various periods of time.
- He found out that he forgot 40% of whatever he had learned in the first 20 minutes.
- After one hour, he forgot 60% while after nine hours he forgot a total of 70% of what he had learned.
- After one day, he could recall only around 30% of the material he learned. After that, his recall was steady for a long period of time.
- This experiment proved that we forget most of the things we learn in a short span.
