Cognitive control
Today, psychologists often debate whether the Stroop effect results from priming mechanisms or cognitive control. Anything that reduces interference when an incongruent stimulus occurs immediately after an incongruent trial rather than a congruent trial, refers to conflict adaptation. By conducting various experiments, researchers have concluded that when the distractor and the target contained different features, or ink colors, there was no conflict adaptation in the Stroop task. The target refers to the ink color, and the distractor refers to the actual word. Another group of researchers studied conflict adaptation without using top-down processing of the current trial, but rather examined a series of trials separated from other expectancies, such as priming. Researchers who explored the conflict-monitoring theory, an alternate view of cognitive control in the Stroop task, found that after a series of congruent trials, participants would automatically assume congruency for next trial. However, a series of incongruent trials decreases the effects of congruency. . After more experiments testing the Stroop effect, psychologists came to the conclusion that there is no Stroop effect when only one letter of a neutral word is colored. They also determined that there is a Stroop effect when all the letters of the word are colored.

Working Memory Capacity with Stroop Interference

After various studies performed on congruency and the Stroop effect, researchers determined that the greatest interference came after congruent trials, rather than after incongruent or neutral trials. Furthermore, the interference following incongruent and neutral trials was the same. Cognitive control can function on multiple levels, and can be understood through bottom-up processing and item-by-item control, in addition to list-level or top-down processing. Cognitive control can result from identifying features, item-by-item, in the Stroop task.

Brain Activity During the Stroop Task

When people make decisions, their brain is actually gathering information from one stimulus versus another over a period of time, resulting in a final choice. The relative weight of the information at the particular stage in the decision-making process determines this choice. Once again, researchers determined that participants are more accurate when the semantic meaning of the word is congruent with the physical color of the word. Researchers studied brain activity during the Stroop task in order to examine the Dual Mechanisms of Control Account Theory, which infers that a reactive control strategy occurs in congruent conditions, and a proactive control strategy happens in incongruent conditions. However, the experimental results did not support the proactive mechanism aspect of the Dual Mechanisms of Control Account Theory. Finally, the data from the fMRI scans during an incongruent task in a "mostly congruent" context showed high activation in the front-parietal area of the brain. Cognitive control helps individuals organize their thoughts inside the brain. A major finding regarding facilitation performance showed faster responses and an increased activation inside the brain before a task begins. Brain imaging studies help psychologists understand conflicts in sets of tasks, switching tasks, and other obstacles within a task.

Multiple problems
I have multiple problems with your addition to the article, to the point that I had to revert it and move it to the talk page to discuss it and improve it before re-adding it.

Technical hints for sourcing
You have made a (small) mess with your system of adding sources. Each of your sources appears as a separate source each time you name it. Also if you take a look at some of the sources already in the article you will notice that they use templates, while you did not. I indicated you on the talk page how to create automatically references. Please do it.

I expand upon the example I gave you in the article talk page:

You added this which gives the following reference

You should have added the following to continue with the style already used in the article: which gives the following reference

Indeed, as I explained in the talk page, you can get all this automatically by simply pasting the doi into the template filler.

Regarding on how to use twice each reference you simply re-added each time the same reference, which leads to the duplication as here.

What you should do is to give a name to the reference which substitutes the first ref in the template as here:  (I chose Helloforexample so it is clear that the name does not matter). This will give the following ref. The next time you want to use the same ref you only have to add the following:  (important: notice the / symbol at the end); and voila: you have two links to the same source.

Content
I do not have the time to elaborate today, but the working memory and brain section are not up to the level of the article. Sources seem cherry-picked as seems content and conclussions.

My recommendation is that you get a more complete picture in one of the sections (probably the one on cognitive adapation), read more about it, add better sources to it and do not loose your force trying to reach too much. There is tons of research for example in brain mechanisms and in two months it is probably way beyond your capabilities to get a good grasp of it...--Garrondo (talk) 17:30, 22 March 2013 (UTC)
