  1. 1. Color Schemes and the Stroop Effect Do different color schemes(cool, warm, pastel, primary) have an effect on how long it takes (measured in seconds) the test subject to complete the Stroop Effect? By Casey Reed
  2. 2. RationaleThis experiment was chosen because HumanBehavioral Science is an interesting topic and isrelevant to daily life, as the conductor and testsubjects of the experiment are human.Hopefully, the experiment accomplished showinghow the human brain responds to various colorschemes used in the Stroop effect.
  3. 3. ResearchThe Stroop Effect was named after J. RidleyStroop, who discovered the effect in the 1930s.The Selective Attention Theory says that aninterference occurs because naming colors requiresmore attention than reading colors does.Automatization is the instinct to only pay attention tothe meaning of a word. After reading for manyyears, when a person sees a printed word it is hard forthem to not read it.
  4. 4. HypothesisIf the five different tests of the Stroop effect has aneffect on the time it takes for the test subject tocomplete each test, then color schemes will effecthow the test subject performs as a result of theSelective Attention Theory.
  5. 5. HypothesisThe four different tests were modified by coloring thewords in each test with different colors. The first testwas the original Stroop test, the second test usedcool colors, the third test used warm colors, thefourth test used pastel colors, and the fifth test usedprimary colors

  7. 7. Procedure1.Welcome the participant and ask the participant to take a seat.2.Tell the participant what they will be asked to do: “I am going toshow you colored words. Do not pay attention to the meaning of theword, just say the color of the word. Try to go as fast as you can. youwill do this fifteen times, three times for each sheet. If you make amistake, you must correct it before you continue with the test. Tell mewhen you are ready to begin.”3.Show participant Test Paper 1 and say go; simultaneously start timer.4.Stop timer when participant completes Test Paper 1.5.Record time in chart6.Repeat steps 3-5 two times7.Repeat steps 3-6 with Test Papers 2-5 8.Thank participant for helping

  12. 12. ConclusionThe problem was “Do different colorschemes(cool, warm, pastel, primary) have an effecton how long it takes (measured in seconds) the testsubject to complete the Stroop Effect?” The problemwas answered as the data clearly showed that varyingcolor schemes affected the time it took for the testsubjects to complete the test.
  13. 13. ConclusionThe hypothesis was “If the five different tests of theStroop effect has an effect on the time it takes for thetest subject to complete each test, then colorschemes will effect how the test subject performs asa result of the Selective Attention Theory, and it wasproven correct because the research showed thateach individual Stroop test had a different averagetime, and some tests had much better averages thanothers .
  14. 14. ConclusionTest 5 had the smallest average time, and Test 4 hadthe largest. The average time it took to read test 4was 17.6 seconds. The average time it took to readtest 5 was 12.46 seconds.The experiment’s results showed that primary colorswere easiest to identify and pastel shades were thehardest.
  15. 15. ConclusionTo improve the experiment, one could create morecolor schemes and have more trials with morevolunteer test subjects. One could have acquire amore accurate time recording device.Many can benefit from the results of this experiment.Students can use the fact that can most easilyrecognize primary colors and use these colors tohelped them memorize things they may need toknow for school. Scientists can also use the results torecord the trends and compare it to other data.
  16. 16. ConclusionFor future research, scientists could narrow down thedifferent colors used in each test to provide moredetailed results. More trials could be taken from testsubjects of different ages to expand the results formore people.
