Thus, in this incongruent condition, participants are required to name the color of the ink instead of reading the word. Conversely, in the third table, named color-word (CW) condition, color-words are printed in an inconsistent color ink (for instance the word “red” is printed in green ink). Two of them represent the “congruous condition” in which participants are required to read names of colors (henceforth referred to as color-words) printed in black ink (W) and name different color patches (C).
In the most common version of the SCWT, which was originally proposed by Stroop in the 1935, subjects are required to read three different tables as fast as possible. It assesses the ability to inhibit cognitive interference, which occurs when the processing of a stimulus feature affects the simultaneous processing of another attribute of the same stimulus ( Stroop, 1935). The Stroop Color and Word Test (SCWT) is a neuropsychological test extensively used for both experimental and clinical purposes. Finally, we underline the importance of assessing the performance in all Stroop Test conditions (word reading, color naming, named color-word). We claim for an alternative scoring method which takes into consideration both speed and accuracy of the response. Furthermore, we discuss several normative scoring methods from the Italian panorama as reported in literature. Our findings show that while several scoring methods have been reported in literature, none of the reviewed methods enables us to fully assess the Stroop effect. We referred to both electronic databases (i.e., PubMed, Scopus, Google Scholar) and citations. We present a systematic review of studies that have provided normative data for the SCWT. The aim of the present work is to verify the theoretical adequacy of the various scoring methods used to measure the Stroop effect. The Stroop Color and Word Test (SCWT) is a neuropsychological test extensively used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute, well-known as the Stroop Effect. 3CiMeC Center for the Mind/Brain Sciences, University of Trento, Rovereto, Italy.2IRCCS Istituto Auxologico Italiano, Ospedale San Giuseppe, Piancavallo, Italy.1“Rita Levi Montalcini” Department of Neuroscience, University of Turin, Turin, Italy.Federica Scarpina 1,2 * and Sofia Tagini 2,3
