This standardised version of the Stroop consists of two parts. In the Colour Task, the individual reads aloud a list of 112 colour names in which no name is printed in its matching colour. In the Colour-Word Task, the individual names the color of ink in which the colour names are printed.
The SNST may be administered and scored by individuals with limited training. Interpretation of the resulting Colour and Colour-Word scores requires professional training in psychology, psychiatry or educational testing.
A stopwatch is required to administer each 2-minute test.
The SNST was standardised on 156 adults ages 18 to 79 years. Norms are provided for two age groups, 18 to 49 years and 50 years and older. The test correctly differentiates 79%-92% of brain-damaged from normal adults. Test-retest reliability is .90.
