Multiple studies, including the original experiments by Stroop, suggest that practice can decrease Stroop inference. This has implications for our learning skills, ability to multitask, and how we form habits.
Kahneman believes by understanding how our brains make connections, we can overcome them to reach more logical conclusions by calling on System 2, our controlled thinking, quicker. Exploring the Stroop effect continues to play a role in studies and experiments involving automatic and controlled thinking, selective attention, our cognitive processing, and more.
Even though the Stroop effect has never been definitively explained, it provides a tried and true benchmark for psychologists and scientists that has been referred to for many years. Does the study of cognitive processes interest you? Consider an online psychology degree from Lesley University.

Graduate School of Education. The issue about the role of reading ability on the SCWT performance cannot be adequately satisfied even if the Victoria Stroop Test scoring method Strauss et al.
In the light of the previous considerations, we recommend that a scoring method for the SCWT should fulfill two main requirements. First, both accuracy and speed must be computed for all SCWT conditions. And secondly, a global index must be calculated to relate the performance in the incongruous condition to reading words and color naming abilities. The first requirement can be achieved by counting the number of correct answers in each condition in within a fixed time Amato et al. The second requirement can be achieved by subtracting the W score and C score from CW score, as suggested by Caffarra et al.
None of the studies reviewed satisfies both these requirements. According to the review, the studies with Italian normative data present different theoretical interpretations of the SCWT scores. Amato et al. Slowing to a response conflict would be due to a failure of selective attention or a lack in the cognitive efficiency instead of a failure of response inhibition Chafetz and Matthews, ; however, the performance in the SCWT is not exclusively related to concentration, attention or cognitive effectiveness, but it relies to a more specific executive-frontal domain.
Indeed, subjects have to process selectively a specific visual feature blocking out continuously the automatic processing of reading Zajano and Gorman, ; Shum et al. The specific involvement of executive processes is supported by clinical data. Patients with anterior frontal lesions, and not with posterior cerebral damages, report significant difficulties in maintaining a consistent activation of the intended response Valgimigli et al.
Furthermore, Parkinson's Disease patients, characterized by executive dysfunction due to the disruption of dopaminergic pathway Fera et al. According to the present review, the heterogeneity in the SCWT scoring methods in international literature, and most dramatically in Italian literature, seems to require an innovative, alternative and unanimous scoring system to achieve a more proper interpretation of the performance in the SCWT.
Further studies are required to collect normative data for this scoring method and to study its applicability in clinical settings. Conception of the work: FS. Acquisition of data: ST.

Introduction The Stroop effect is one of the best known phenomena in cognitive psychology. The Stroop task In the Stroop task, people simply look at color words, such as blue, red, or green. Even though it was developed in the s, the Stroop task is still frequently used in cognitive psychological laboratories to measure how well people can do something that clashes with their typical response pattern. This task requires a certain level of "mental control".
That is, you need to be aware of the task you are doing now and ignore how you would normally respond to words. This requires "control" over your own default cognitive processing. The Stroop effect As you now understand, the Stroop effect is the degree of difficulty people have with naming the color of the ink rather than the word itself. This is mainly for practical reasons.
That is, it is easier to measure the exact time a button press takes place than to measure when people start saying a word using voice-key technology.
