Today we did a small experiment on short-term memory. We were given sets of numbers verbally, after that we had to record what we heard on the paper. The digits increase as we progress. Out of a perfect 12 score, we found out that the class average is 7 ± 2 digits. During the experiment, it was very easy to do the first three numbers, but the fourth number start to bring some hesitation to some people. From number five onward, many people no longer look at ease. Most people end at around the fifth number , some went further.

We had reached a conclusion about the human memory
- It is easier to remember through the method of “chunking”, which is to group similar number sequences together.
- Human remember things more easily if the information appear to have some sort of meaning they can associate.
