Transcript of Science Project
2. Label each paper (#1-7) This will be its test number that it is recognized by
3. Cut the papers in to horizontal strips
4. Label each strip with a number (#1-10)
5. Label different envelopes (#1-7)
6. Put each set of 10 strips in to its respective envelope
7. Make an answer sheet for each envelope by typing the ink color of each word in order from strip #1-10
8. Print out all the answer sheets
9. Create two blank 20 x 7 spreadsheets to record task completion time and errors made during each test Some Things I Learned.. The Stroop Effect was first discussed in 1935
by John Ridley Stroop in an Experimental Psychology Journal The Stroop Effect Test.. Circular Warped Words Stroop Effect Test.. Purpose.. Procedures.. Materials.. I chose my topic because in the past I have been a volunteer in a Stroop Effect Experiment. My reaction time during the test always intrigued me. My experiment gives me the opportunity to test if it's possible to "cheat" on the S.E. Test by warping and manipulating how the word appears. More Materials... 6. Answer sheets for all 7 sets of 10 paper strips
7. 7 Envelopes to organize 7 sets of 10 paper strips
8. Written out instructions to read to all volunteers
9. Well-lit area
10. A table
11. 2 chairs Hypothesis... If there is some sort of manipulation or warping of a word, then it will decrease or eliminate the affects of the Stroop Effect on a test volunteer who takes the test. Conclusion... Backwards & Circular Warped Words Stroop Effect Test... Thank you for watching my
presentation 1. 20 Test Volunteers
2. Two 20 x 7 Blank Data Collection Sheets (To record: Task completion time and number of mistakes in each test
3. 7 sets of 10 paper strips that have different variations of the Stroop Effect Test (e.g. warped, backwards, matching or un-matching ink)
4. Timer App on iPod Touch 4th Generation
5. Pencil and Pen Pre-Experiment 10. Print out both spreadsheets
11. Label first spreadsheet (going vertically on the left: volunteer's name. going horizontally across the top: age, gender, test #1-7)This will be used to record task completion time
12. Label second spreadsheet (going vertically on the left: volunteer's name. going horizontally across the top: age, gender, test #1-7) This will be used to record errors made during each test 13. Find 20 test volunteers Experiment.. 14. Have the volunteer sit down at a table in a well-lit room
15. Place the first 10 strip set face down in from of them spread out from top to bottom going in chronological order
16. Read the pre-written instructions: "You have been given cards containing a sequence of words printed in colored ink. The ink colors used are red, blue, green, brown, and purple. The task is to call out the ink color of each word [or circle] as quickly as possible without making a mistake. Do you understand the instructions?" 23. Record their results on the two spreadsheets in pencil
24. Repeat steps 15-23 with all seven tests Result Charts The Stroop Effect stimulates 2 parts of the brain: the Anterior Cingulate Cortex and the Dorsolateral Preforental Cortex. Both of these parts of the brain are located in the frontal lobe In the end, my hypothesis was correct. In my data, as the non-matching color-word sets became more warped, the average task completion time and average number of mistakes made during each test depleted. 17. Open the timer app18. Let your volunteer know you are about to start the timer by saying, "Ready, set, go". 19. Start the timer 20. Read along on your answer sheet while your volunteer attempts to call off the ink color of each word on the 10 strips 21. Keep a tally of how many wrong answers the volunteer get wrong22. Stop timer when volunteer has completed the task of reading off the ink colors in the set of words Would anyone like to demonstrate?
