Human Memory

In psychology, memory is an organism's ability to store, retain, and subsequently retrieve information.

There are two kinds of memories1. Short Term Memory

• Short-term memory allows one to recall something from several secondsShort term memory allows one to recall something from several seconds 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 memory can store much larger quantities of information for• 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

Usability

Usability is the “effectiveness, efficiency and satisfaction with which a specified set of users can achieve a specified set of tasks in a particular environment.” –I t ti l St d d O i tiInternational Standards Organization

• Minimizes burden• Minimizes burden.

• Reduces Workload.

Importance of Usability

If website is difficult to use.....................................

If the homepage fails to clearly state what a ff d h t d th

people leave

company offers and what users can do on the site.........................................................................

If users get lost on a website.................................people leave

they leaveIf a website's information is hard to read or doesn't answer users' key questions..................... they leave

The first law of e-commerce is that if users cannot find the product, they cannot buyit either.

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.
