P0347 - Validation and normalisation data for the Stroop, TMT and N-back tests in the Polish population

Abstract

Neuropsychological assessment of prefrontal cortex activity included several tests: The Stroop Color Word Interference Test is a method for the assessment of verbal abilities, attention, verbal working memory and executive functions, whereas Trail Making Test measures psychomotor speed, the ability to shift strategy, executive functions and visuospatial working memory. The N-back Test measures visual working memory and visuomotor abilities. Normalization of these tests for Polish population has not been done so far. The goal of the study was exploratory analysis of possible associations between performance of the Stroop Color-Word Interference Test, Trail Making Test and N-back Test in healthy subjects and basic demographic features. The study included 200 healthy volunteers (100 male, 100 female), aged 18-60 (mean 32±10,6) years.

Results:

Highly significant associations between age and performance on all tests was found. Additionally there was negative correlation between years of education and time of performance on the Stroop Test part A and also positive correlation between years of education and number of correct responses on the N-back Test.

Conclusion:

Obtained result are consistent with the findings of other normative studies for these neuropsychological tests: Bulock et al., 1996, Ivnik et al 1996, Hays 1995, and Smith 1996.
