At every subway station, there is a black and white striped sign. It is in the exact same spot at every station. The conductor of the train must point to it at every station to prove that he is paying attention. They chose black and white because the contrast is very big, and easy for the eye to see.
Color contrast is used in our world in many ways.
Things such as traffic signs, and chalkboards in
classrooms have very specific contrast to make
it easier for the brain to understand.
1. Each student is brought to a quiet exam room (classroom).
2. Present 1st presentation (white on green)
3. Questions. (Test memory) measure time
4. 2nd copy
5. Questions. measure time
6. 3rd copy
7. Questions. measure time
8. 4th copy
9. Question. measure time
10. 5th
11. Question. measure time
12. Repeat for other 19 people
13. Score and insert results in data table.
In our experiment, we wanted to test the effect of color contrast on the human brain, and specifically, memory. Which color causes the most eye strain?
White on green is easier for people to read and is the easiest to memorize. We also predict that this is the reason why public signs such as road signs and blackboards are white(chalk) on green.
- quiet exam room
- stopwatch
- 10 male 7th graders
- 10 female 7th graders
- 5 presentations (different colors)
- 1st copy= white on dark green
- 2nd copy= black on white
- 3rd copy= white on black
- 4th copy= yellow on red
- 5th copy= orange on blue
- 20 words on each slide and 20 questions (yes or no questions. was this one of the words?)
- answersheet
In conclusion, we found that the girls
did better in our test. Also, the hardest
test in general was yellow on red. The
easiest one was white on black. This refutes our original hypothesis.
From the results, we can conclude that for the male students, yellow on red was the hardest for them to memorize, and for the female students, orange on blue was the hardest. The averages also show that girls do better in these memory tests. However, the times did not correspond with the scores. The times may not have been precise because the stopwatches were manually operated, and the stopwatch may have not started exactly when the question slides came on. Finally, when we paused the presentation right before the question slides came on, we had to explain what they had
to do. The time (pause) we took were different for
every student, which may have affected
our results.
