Short Term Memory

We did an experiment in class to test out memory skills. Mr Anthony read out numbers and we tried our best to remember the digits. He first started out with 3 digit numbers and increased a digit every time. I could remember 8 digits and the average of the world is 7 plus minus 2. This was used to test our short term memory. We discovered that the hardest numbers to remember were the ones in the middle. This is because of the serial positioning effect. However we can increase our short term memory for numbers by a method call chunking. Chunking is way to group numbers and pick patterns to help us memorize more digits. Numbers are hard to memorize because they have no emotional or memorable attachment to it. And it also because there is no visual aids to help us out.
