**We'd like to thank all of the judges we've met through the regional and national science fairs who posed some very interesting questions.**
Why did you pick these colors? [top]
We chose these colors because they are the main colors of the visible light region of the electromagnetic spectrum. We wanted the colors used to be simple and common.
Why did you hypothesize violet to score highest? [top]
After completing our preliminary research into color and how the brain was affected by it, we hypothesized that violet would score the highest because we thought that violet's high frequency would allow the brain to be more stimulated. Much as a person is generally more stimulated by someone who is yelling at them, than someone who is speaking in a monotone voice.
Why the time limit? [top]
We instilled the time limit for two reasons. We conducted our testings during school hours, thus, it would be unreasonable to let the students complete the tests as they were in the middle of class. Also, we used a time limit to keep the testings fair between students.
What variables did you control? [top]
As mentioned above, we controlled the timings of the tests. Also, we controlled the time of day that the tests were taken, all tests being taken a 10am. We controlled the spacing in between tests (1 week) and we controlled the academic standing of the subjects (all subjects were grade 9 academic level math students).
Where did you get the questions for the tests? [top]
We made up all of the questions used on the tests ourselves.
How did you keep the tests fair? [top]
We did not want to use the same test for all colors so we had to find a way to make all of the tests fair. To keep the tests fair, we used the same number of digits in each question. For example, the first question of all of the tests is a two-digit number multiplied by a one digit number and so on for each question of the test.
Why didn't you include white with your testings? [top]
Because we based our hypothesis on wavelength, we did not include white. White is a combination of all the spectral colors and does not have a specific wavelength.
How long did this project take to complete? [top]
Our project was started in October 2002, and was completed in April 2003.
What if Subject #001 is smarter than Subject #065? [top]
This does not matter at all. We were not measuring how smart each subject was, we only wanted to compare the results. A 20% student could have the same differences in score between colors as a 70% student. The differences in between colors were the only important parts.
What about pre-conditioning? [top]
Pre-conditioning is the belief that as someone performs a task multiple times, their skill level increases as the trial increase. To avoid this factor, we conducted the testings once a week. We did not want the tests to be given very closely together to avoid possible pre-conditioning.
If you could continue on with this project, what would you like to do? [top]
Our project could lead into many further studies. A few areas we would be interested in exploring further are:
- increasing number of subjects
- adding more colors, color combinations
- using white, black, gray tests
- using colored ink on white paper
- possible lab work with brain response testing
