Psychology Experiment. The study that is being replicated is the first experiment of J.R. Stroops The Stroop Effect, which involved the effect of interfering color stimuli upon reading names of colors serially.

Introduction

Introduction In a study of cognitive interference, J. Stroop was able to exemplify that when two stimuli are occurring simultaneously, brains will only be able to respond to one, and thus the verbalization process is compromised. Redding and Gerjets showed that manually responding to stimuli had a greater or lesser effect on the interference, showing that responding manually to a stimulus would be able to occur more quickly while making more errors. The study that is being replicated is the first experiment of J.R. Stroop's The Stroop Effect, which involved the effect of interfering color stimuli upon reading names of colors serially. Mr. Stroop placed colors into two groups; reading colors that were in a color that was not the same as the color of the word themselves, and reading color names printed in black. The result was that participants were able to say the word faster and with less errors in reading words written in black. Less interference allowed the participants to perform better. The aim of this experiment is to show that cognitive interference occurs when someone is faced with two stimuli at the same time. Method Design This experiment used a repeated measures design to show the effect the two different sets of words would have on the ability of a person to verbally respond. ...read more.

Middle

It is evident that it took longer to read each word; in the ones printed in black, on average, a participant would take .38 seconds, (rounded to the nearest hundredth) and would take .44 seconds per word on the words that were printed in colors other than that of themselves. Discussion In the original Stroop effect, J.R. Stroop used 100 words for the colors printed in black and the ones printed in colors; in this experiment, 36 words were used for each, so the time it took would evidently be longer with J.R. Stroop. In the experiment he performed, he saw it took each participant .41 seconds to read each word printed in black, and .43 seconds to read each word printed in color. In this experiment, the results were similar. On average, it took .38 seconds to read each word, in the words printed in black and .44 seconds to read the ones printed in colors. *To account for errors that were left uncorrected, a participant's time was divided by the amount of words of the sheet, 36, and for each word, that time was doubled, also done by Stroop. There is a slight difference in the quickness of reading the black words from this experiment to J.R. ...read more.

Conclusion

In the original experiment, when the color of the word was different than that of the actual word, it took the participants longer to read the set of given words. When the words were read in normal black ink, it took less time than in a color other than the word. The results of the experiment that you participated in coincided with the expected results.
