Notes: Results from the CWIT, based on the Stroop effect. All variables were statistically equal between the pTMD group and the control group. Presented results are in seconds for S1, S2, S3 and S4. Additionally, two variables were calculated, including contrast inhibition (contrast S3), and contrast switching (contrast S4).
