Great explanation! I have a question regarding the typical scores clients achieve in the C-W stimulus task, where they have to name the color the text is printed in (not read the word). Specifically, I’m curious about what scores are commonly observed at the 45-second and 120-second marks. In my university assignment, it says that individuals who score below 99 raw within 120 seconds are suspected of having brain damage. However, I’ve administered the test to three clients, and none of them were able to achieve more than 70 raw score in the given time. Am I misunderstanding something about the scoring process? Would really appreciate your input!
At stoeltingco.com/stroop there are links to resources, such as presentation slides: stoeltingco.com/Psychological/media/Stroop_International_Neuropsych_Presentation.pdf. You can see average scores from the normative update sample. For C-W the mean is ~42 words in 45 seconds. That's almost a word a second, so only 70 in 120 seconds does sound low. There may be differences in the version you are using or in your administration procedures, if you are seeing this result from typically functioning individuals.
You should persist in saying “No” until the response is correct. There is no other way to mark errors, so this is how errors are accounted for. If someone persists in stating the wrong answer repeatedly, it is likely that there is some impairment that should be assessed separately.
The problem is that the tables in the manual are really confusing. For example, the table IV for obtaining the T scores are not clear on what is the “deviation score”? Could it be the residual score that we have to calculate and write on the booklet table? If so, why not just call it “residual score” so that it is consistent with what’s in the booklet? Or is the “deviation score” column on the table, actually the T-score? I cannot find the answer to this mystery!
@Livia Pontes, you are correct that the terms "deviation" and "residual" are synonymous here, that is, the difference between actual and predicted performance on each of the scales. Sorry for the confusion! There is a new normative update version that aims to clarify some confusing points with the scoring like this: stoeltingco.com/stroop.
Saloni, the procedure for calculating T-scores, along with the tables for doing so, is explained in the manual. Basically, for each of the three scales (Word, Color, and Color-Word), you will consult the appropriate table and obtain a predicted score for each scale, based on age and education. You will then subtract that predicted score from the actual score, calculating a residual. The equivalent T-score for each of those residuals is listed as a separate table. The Interference T-score calculation is similar, but the predicted score is based on Color and Word score. We also have a scoring application that will do all that for you, too: stoeltingco.com/stroop
Thank you Sir for such a elobrate vedio...can u tell me the reference of this procedure or any authicated article which tells us the same thing as u have shown in the vedio for citing in reasearch article
Hi @shivani soni, the manual is available for purchase by qualified mental health clinicians at: stoeltingco.com/stroop. A scoring application is available there, as well. There is a new video that provides instruction on scoring the test at: ua-cam.com/video/PWTLlkuJb0k/v-deo.html.

It really helped me... thank you so much
Glad it helped! Please let us know if any other questions come up: www.stoeltingco.com
@@StoeltingCoPsychology sure i will definitely ask you guys the questions because I often do experiments.
If a client gives an incorrect response after being cued "no" do you persist until they correct it or mark an error and continue?

Can you please share the pictures of the manual for write up
For instructions scoring and other calculations
