Short Term Memory • Short-term memory allows one to recall something from several seconds Short term to as long as a minute without rehearsal. • George Miller in his paper ‘The magical number 7 +/- 2’ suggested that the store of Short term memory was 7 +/- 2 items. • Memory capacity can be increased through a process called chunking. 2. Long Term Memory • • Long-term Long term memory can store much larger quantities of information for potentially unlimited duration (sometimes a whole life span). Short-term memory is supported by transient patterns of neuronal communication, dependent on regions of the frontal lobe and the parietal lobe. Long-term memories, on the other hand, are maintained by more stable and permanent changes in neural connections widely spread throughout the brain

For intranets, usability is a matter of employee productivity. Time users waste being lost on your intranet or pondering difficult instructions is money you waste by paying them to be at work without getting work done. Current best practices call for spending about 10% of a design project's budget on usability.
