(Faculty.washington.edu, n.d) Most people would say that naming the color of incongruent color words would be easy. However, in 1935, John Stroop’s experiment demonstrated that it is harder than it looks. In 1935, John Stroop published his research “The Stroop Effect”. Ever since the article was published 500 studies were published but in different forms. The Stroop effect has been the main experiment and more research has used this experiment for different research purposes. The picture-word interference experiment is another version of the Stroop effect experiment and it is known as the best. For example, they would use a picture of an elephant, but they would insert the word horse in the center of the picture. They found some difficulty in reading the word inside the image; however, naming the image without the word was done easily. Another version of the Stroop effect experiment was the directional version. They would use arrows and words describing it in the opposite …show more content…
The healthy participants were tested healthy by using structural clinical interview. Any participants that had a history of mental disorder, besides the regular phobia and psychotic disorder in the first-degree family history, were excluded from the experiment. The single-trial Stroop and the card Stroop were both used in this experiment. They wanted to discover if the reaction time and the accuracy measure would have a different outcome with both groups When they carefully examined the previous card Stroop studies, it showed that there was a difference; However, in this research they failed in finding a difference in the reaction time using card Stroop with the schizophrenic patients. Moreover, there was a difference when measuring the accuracy rate, so this shows us in regard to the previous studies it is important to measure both accuracy rate and reaction time. (Perlstein et al, 1998) Another example is the study regarding the Stroop effect, there was two studies done using the Stroop test for patients with bipolar
