Demonstration 1: Short-Term Memory

We had an activity in class concerning short-term memory of numbers. Mr. Anthony said digits of numbers out loud, and we had to recall those numbers and write them down. The first group of numbers started with 3 digits, and with increasing group, one more digit is added.

I got all the numbers correctly until line four, which means the 6-digits of number while some classmates got lower (5 digits) and some got higher (7-9 digits).

To conclude the demonstration, Mr. Anthony explained about the capacity of a human’s short-term memory; it can only store 7 pieces of information at the same time—give or take 1 to 2 pieces. There are two ways to improve the capacity of short-term memory of numbers; the first is to relate those numbers into an event or anything that can related to, and the second is to chunk those information together into groups.
