Abstract:

The aim of this experiment was to investigate the level of interference on attention when naming colors in conflicting word with the color and the color by itself.  The hypothesis was that the third stimuli would take longer than the other two. This experiment was to replicate John Ridley Stroop’s experiment “The Stroop Effect” in 1935. The experiment had three different stimuli. These stimuli consisted in several words that had to be read by the subjects as fast as they could. The experiment was conducted in the American School of Tegucigalpa. The last stimulus proved to be hardest for all of the students.

Introduction:

The aim of the study mainly was to investigate the level of interference on attention when naming colors in conflicting word with the color and the color by itself. The first stimulus consisted in names of colors written in black font on a white sheet of paper. The second stimuli consisted of the names of colors written in the same color as the name on a white piece of paper. In difference to the other stimuli, this one was the hardest one by the results; this stimulus consisted in the names of colors written in different font color and on a white sheet of paper. The experiment was conducted in the American School of Tegucigalpa and each student was taken out of their class for 5 minutes to perform the experiment. The study was being replicated because that is exactly what J R Stroop did when performing the original “Stroop Effect.”

Method:

Design: The experiment was conducted on a separate room that was deserted. There was only the presence of one participant and the conductors. We asked for permission of a teacher to use 18 of his students for one day to perform the experiment and each of the students were handed consent forms explaining the process and requiring to be signed by their parents if the participants were below the age of 16. Our independent variable was the third stimulus, which consisted of a word that meant a color, but it was written in an incongruent color to the meaning. There were 24 words on the paper. The dependent variable was the time it took the participants to name the colors.

Participants: All of our participants were from 10th grade and they were in the Biology class. We were on our G Period when we performed the experiment and most of the participants were between the ages of 14 and 15. We varied on the genders so we chose 9 males and 9 females for the experiment.

Materials:

  • Stimuli # 1 in black font color
  • Stimuli # 2 in colored fonts that matched with the names
  • Stimuli # 3 in font color that didn’t match the name
  • Stopwatch
  • Pencil and paper for notes and data

Procedure: 

  1. Choose wisely the ...
