demenstration short term memory

Today we demonstrated the ability to remember things such as numbers using short term memories. We later were told to record the numbers that the teacher said. The capacity of human's average short term memory is around 7 characters (plus minus 2). We concluded that there are many ways to improve our memories such as putting the numbers in to chunks (chunking) or relate the facts to our self (self reference effect). We also learnt that we could use some mnemonic devices to help us remember.
