The Stroop Effect
In psychology, the Stroop effect is a demonstration of interference in the reaction time of a task. When a word such as blue, green, red, etc. is printed in a color differing from the color expressed by the word’s semantic meaning (e.g. the word “red” printed in blue ink), naming the color of the word takes longer and is more prone to errors than when the meaning of the word is congruent with its ink color. The effect is named after John Ridley Stroop who first published the effect in English in 1935. The effect had previously been published in 1929, but only in German. The original paper has been one of the most cited papers in the history of experimental psychology, leading to over 700 replications.
The effect has been used to create a psychological test which is widely used in clinical practice and investigation. The test has also been further modified to investigate very different phenomena.
Thank you this helped me with my Science Fair poject. Very useful. Great pictures by the way.
