•There are three main types of memory: sensory, short term, and long
term.
•The short term memory, which is the focus of this experiment, can
store an item for roughly 20 seconds.
•Short term memory has a limited amount of storage. The most widely
accepted amount is 7±2 elements.
•An ‘element’ can consist of numbers, words, letters etc.
The purpose of the experiment is to find the best color for displaying text.
While the range of applications are limited to computerized displays and
items that mainly apply to short term memory, the results can still apply
to a wide range of situations. An initial application could be websites:
any information that needs to be remembered while someone is
navigating, such as directional information and instructions. This can be
expanded to games for quickly memorized instructions and directions
plus many other related uses.
There will be no difference in memorization
between the differently colored characters

•Digital projector
•Randomly generated letters
}
•Test
1. Create groups of randomly generated characters.
In this experiment, five groups of three letter-only
characters were used.
2. Display characters on the projector for ten seconds
then, remove the characters showing a blank
screen for ten seconds.
3. finally, instruct the subjects to write down as much
as they could remember.
4. Collect and record data.
Limitations:
This project only applied to a rather narrow range
of applications and situations. More experiments
would be helpful in understanding the effects of
color in long term memory, non-computerized
display situations, and a wider range of
representational options including background,
and font-type.
