Demonstration 1: Short Term Memory

This demonstration deals with our short term memory. I clearly indicates the capacity of our short term memory.

First, Mr. Anthony read out a three-digits number, then students would write that number down, showing that we remember the number. Then, one more digit will be added each time. The numbers went on to 12 digits. After the read out of numbers, the class compare what they wrote with the actual numbers that were read. All of the students can remember at least 5 digits and at most 9 digits, with the mean of 7 digits, the magic number "7"

This number 7 corresponds with the research that said that we can whole about 7 peices of information in our short term memory. the only way to imoprove this is to seperate the numbers into chunks. For example, chunk 19900730 into 1990 and o730. Then try to make sense of the numbers. 1990, my year of birth, 0730 my month and date of birth. This techniques of associating short term memory with long term memory will help improve our the capacity of short term memory.
