  Vanderbilt University Register: Stroop effect helps put Vanderbilt on psychology map
That is the essence of the Stroop effect, which was discovered in the 1930’s by John Ridley Stroop as part of his doctoral thesis in psychology at George Peabody College for Teachers, which is now part of Vanderbilt.
In the realm of cognitive psychology, the Stroop effect and the variations that have been developed on the original theme have found increasing importance because they represent a unique window into the interplay between mental processes that are automatic and those that are under conscious control.
Stroop was born in 1897 on a farm in Hall’s Hill, the fifth of sixth children.

 STROOP LAB
The primary purposes of the lab are to replicate and investigate the Stroop Effect.
The classic demonstration of the Stroop effect is produced when one tries to name the color of the ink in which a word is printed when the word itself is the name of a color other than that of the ink (Reed, 1988).
Stroop effect Describe briefly the method of the current experiment Describe potential results, such as ³If subjects experience Stroop interference, then we would expect to observe...², for both of the major investigated effects (i.e., replicate major effect and impede reading of words).

 Psychology 132 - Stroop Effect
It is also interesting to note that Stroop developed his color word-task less from an interest in stimulus-naming time than from an interest in interference between conflicting processes.
There are a number of theories regarding the Stroop effect; however, the discussion here will focus on attention as it applies to two types of cognitive processes: automatic versus controlled processes.
From this traditional view point, the Stroop effect is a relatively clear example of competition between an automatic (color word reading) and a controlled (ink color naming) processes.

The effect is made more interesting by the fact that, when asked to read the word in the incongruent condition (e.g., saying "green" to the word GREEN printed in red ink), there is virtually no decrement relative to the usual control (i.e., saying "green" to the word GREEN printed in standard fl ink).
J. Ridley Stroop and Zelma Stroop are buried in Woodlawn Cemetery in Nashville, Tennessee.
Stroop's dissertation research was carried out in the Jesup Psychological Laboratory under the supervision of Professor Joseph Peterson, who was clearly influential in Stroop's choice of a dissertation topic (see the footnote and introduction to Stroop, 1935a).

 The Reverse Stroop Effect
In the Stroop (Color) condition of this experiment, participants were required to respond to the color that the target word was printed in, ignoring the word itself (which named a different color).
Although some Stroop interference remains, it is clear that it is inconsequential relative to the Reverse Stroop effects.
The nearest predecessor of the present effect is probably the work of Flowers (1975), discussed earlier, in which a Reverse Stroop effect was demonstrated.

Münsterberg (1892) studied the inhibiting effects of changes in common daily habits such as opening the door of his room, dipping his pen in ink, and taking his watch out of his pocket.
441) concluded that "the interference effect of an association bears a constant relation to the practice effect, and is, in fact, equivalent to it." Both Bair and Culler found that the interference of the opposing habits disappeared if the habits were practiced alternately.
This suggested a comparison of the interfering effect of color stimuli upon reading names of colors (the two types of stimuli being presented simultaneously) with the interfering effect of word stimuli upon naming colors themselves.

Their idea is that in the classic Stroop effect, the variation or discriminability of the word is greater than the discriminability of the color.
According to the introduction of Stroop effect above, the reason for this is because English has not been "automated" enough to me. So I decide for the first experiment, I am going to extend the traditional Stroop effect study to another language; more specifically, to compare the result of bilingual people in two different languages.

This removed the essential conflict that usually occurs within the brain during the Stroop test, allowing participants to identify the color of the characters on the screen as efficiently as if they were simple blocks of color.
Besides putting a dent in the inviolability of the Stroop effect, the findings may have implications for research into other areas of suggestion and attention.
This seems to be a top-down effect that may be able to override a whole range of impulses," he said.

 Demo of Stroop Effect
John Ridley Stroop first reported this effect in his Ph.D. thesis published in 1935, commonly known as "Stroop Effect":
The reaction time is an indicator of the "attentional process" in the brain – it increases with attentional fatigue and/or inattentiveness.
Thus, Stroop Effect is widely used to indicate mental process of attentional fatigue and/or the decreased ability to inhibit ongoing competing conflicts often associated with ADHD.

Virzi & Egeth (Memory & Cognition, 1985) developed a model of the Stroop effect using the concept of a translation mechanism.
Thus, the Virzi & Egeth (1985) model is expanded in the diagram below to delineate the localization of the neural processors involved in the Stroop effect.
The present "synaptic distance" model can be tested by using a Stroop task in which the words UP and DOWN are shown in a top or bottom position either in the left or right visual field (RVF and LVF boxes).
