Stroop Test

The Stroop Color and Word Test was designed to differentiate between individuals who are non-brain damaged and individuals with brain damage. This brief five minute test is applicable for those between the ages of 15 and 90. This test remains a standard measure in neuropsychological assessment. It assesses cognitive processing and provides valuable diagnostic information on brain dysfunction, cognition, and psychopathology.

The Stroop Color and Word Test is based on the observation that individuals can read words much faster than they can identify and name colors. Whether the test is used as a screener or as part of a general battery, its quick and easy administration, validity, and reliability make it a highly useful instrument.

How to Use the Assessment
The Stroop Color and Word Test consists of a Word Page with color words printed in black ink, a Color Page with ‘Xs’ printed in color, and a color-Word Page with words from the first page printed in colors from the second page (the color and the word do not match). The respondent goes down each sheet reading words or naming the ink colors as quickly as possible within a time limit. The test yields three scores based on the number of items completed on each of the three stimulus sheets. An Interference score, which is useful in determining the individual’s cognitive flexibility, creativity, and reaction to cognitive pressures also can be calculated. A stopwatch is required to administer each test.
