Science Fair - Stroop Effect

  1. 1. By Haneen Yusuf
  2. 2.  I hypothesis when a word is written the same as its ink color, its color will be recognized and read easier and faster than a word written different as its ink color. I base my hypothesis on results of similar test I have taken.
  3. 3.  The purpose of this experiment was to test the difference in the time it takes for a person to correctly recognize the ink color of a word instead of reading the word itself. I became interested in this experiment when I heard of it and tried it myself. The information gained from this experiment will help others by showing them how their brains work.
  4. 4.  1 computer with color printer. Five sheets of cardstock. Five envelopes Both male and female volunteers to take a simple color – naming test.
  5. 5. 1. Print color words printed in matching color ink (red blue green black yellow).2. Print color words in different color ink (five examples of each different color (red blue green black yellow).3. Print words on cardstock (for sturdiness).4. Cut words in horizontal strips.
  6. 6. 5. Lightly label the back of the strips, and keep the two sets in separate envelopes.6. Perform this test in a quiet place with no distractions.7. Ask volunteers to call out the ink color as they read through the strips as quickly as possible without making mistakes.8. Time how long it takes for the volunteers to name the colors of the non-matching words.
  7. 7. 9. Time how long it takes for the volunteers to name the colors of the matching word.10. For half of the volunteers, reverse the order and have them name the colors of the matching word first.11. Calculate the average time to name the colors for each word list.
  8. 8. 12. Calculate the time difference for each volunteer (ex: non - matching word time minus matching word time).13. Calculate the average difference for the group of volunteers.14. Make bar graphs to illustrate results.
  9. 9.  The human brain is what makes each person unique. This project will test the difference in the time it takes for a person to correctly recognize the ink color of a word instead of reading the word itself. The procedure included testing volunteers’ ability to say words as fast as they can. The first set or words were written in the same ink colors as the word and the second set was written in the different ink color of the word. The results showed that the majority of the volunteers recognized the words with the same ink color faster than the different ink color.
  10. 10.  It took the volunteers almost twice as long to recognize the words written in the different ink color. This is known as the Stroop Effect. The major conclusion found in this experiment was that when the brain is trained to recognize words written in a certain way the words become a little more challenging to recognize those same words when they are twisted or written in a tricky way. Further studies could investigate if the brain could be trained to recognize two different things at the same time. This study could help educators decide which is the best way to teach children how to read better.
  11. 11.  The purpose of this project is to test the difference in the time it takes for a person to correctly recognize and read easier and faster than a word written different as its ink color. My results indicate that the words with the different ink color take longer to read. The most time the volunteers took while doing the experiment that was written in the different color of the word was about 17.2 seconds. The most time the volunteers took while doing the experiment that was written I the same color as the word was about 9 seconds.
  12. 12.  On average, volunteers had a harder time recognizing words that were written in different colors. Both male and female were not able to read the words as quickly as they did with the words with the same ink color. As shown in the graph, males read the words a little faster. When the volunteers tried the words with the same ink color, they did much better. Volunteers read the same ink color almost two times faster than the different ink color words. It should be noticed that some volunteers became frustrates whey they were reading the words with different ink color.
  13. 13.  Can the human brain recognize words that are written in different ink color as fast as words that are written in same ink color? When forty volunteers were shown six words, write in different colors, and asked to read the color, not the word, out loud, they were not able to recognize them as fast as they did when the words were written in the same ink color. It took the volunteers almost twice as long to recognize the words when they were “tricky”. Earlier studies have shown that the human brain is trained from a very young age to recognize words. The more often the brain sees certain words; the faster the person will be able to read it.
  14. 14.  Reputation also helps the brain recognize the word faster. When the color blue, for example, written blue, volunteers were able to quickly say blue because the brain recognized both the color and word the same. Now when the word white was written in a red color, white, and the volunteers were once again asked to say the color, it took them longer to ignore the word and only say the color. It is possible that people could recognize tricky words if they were given more time to study them. This study could have better controlled if the volunteers were given more than one try to say the words.
