Demonstration 2: Words
Mr. Peter read out words and we were asked to remember them.
After hearing the first few words I kind of gave up since there were just too many of them, i thought. When the list of words ended, Mr. Peter asked how many people can remember each words. The graph of number of people who can remember words from the beginning to the end seemed like to form a curve going down and up. This is due to the position effect. That we tend to remember things near the beginning and the end.
However, I was able to remember "pineapple" this clearly shows that distinctive item are more easily registered into memory.
He also demonstrated dejavu effect. Because some of the words were related to sleep, some people, including I, imagined that we heard the word "sleep".
The average number of words people can remember was 7, again, which is the average number of information we can store at a time.
