Introduction: Many studies have revealed that drug addicted individuals exhibit impaired performance on executive function tests but a few studies have been conducted on executive functions of drug addicts in Iran. To contribute to this understanding, the present study was designed to assess some domains related to executive functions including cognitive flexibility, attention and speed of men...

BACKGROUND The Stroop Color-Word Test is a classic instrument for the assessment of selective attention and inhibition control and is a highly utilized instrument in research aspects of executive functions of the brain. The purpose of the present study was a preliminary standardization of Stroop test among Iranian bilingual adolescents. METHODS In this study, 150 subjects, including three gro...

BACKGROUND Attention Deficit/Hyperactivity Disorder (ADHD) is a common neurobehavioral problem in children throughout the world.

The Stroop Color-Word Test was administered to 1,856 cognitively screened, healthy Dutch speaking participants aged 24 to 81 years. The effects of age, gender, and education on Stroop test performance were investigated to adequately stratify the normative data. The results showed that especially the speed-dependent Stroop scores (time to complete a subtest), rather than the accuracy measures (t...

Previous studies on brain activity during the completion of the Stroop test focused mainly on finding differences between brain activity during the completion of the congruent and incongruent parts of the test. Based on the results of those studies, the key role of the DLPFC and the ACC was emphasized in solving the cognitive conflict accompanying the completion of the incongruent part of the S...
