In just 5 minutes, the SNST briefly assesses cognitive processing and provides valuable information on brain dysfunction, cognition, and psychopathology—all of which affect an individual’s ability to cope with cognitive stress and process complex input. Results may highlight the need for more specific testing.

  • In the Color Task, the individual reads aloud a list of color names in which no name is printed in its matching color. In the Color-Word Task, the individual names the ink color in which the color names are printed.
  • Norms are provided for two age groups, 18-49 years and 50 years and older.
  • The test correctly differentiates over 79% of brain-damaged adults from normal adults. Test-retest reliability is .90.

Note: Stopwatch is required for administration.
