NEW! The Stroop Color and Word Test aids in diagnosis of brain dysfunction and the evaluation of stress, executive functions, and cognitive abilities. The Stroop phenomenon is useful in the identification of a number of significant disorders and has been recommended as a test for ADHD, dementia, and traumatic brain injury and to ascertain the degree of independence likely to be achieved by individuals with frontal lobe disorders. The cognitive dimension tapped by Stroop is associated with cognitive flexibility, resistance to interference from outside stimuli, creativity, and psychopathology--all of which influence an individual's ability to cope with cognitive stress and process complex output.

Since it requires only five minutes to administer, the Stroop Color and Word Test is an exceptionally useful screening instrument, which may be used alone, or as part of a larger screening battery. The Stroop is used extensively in research, particularly in clinical trials, as a well-research instrument sensitive to comparing changes in functioning between experimental and control groups.

Test structure

  • Each Stroop Test Booklet consists of three basic parts: Word Page--the names of a color printed in black ink; Color Page--semantically meaningless symbols (X) are printed in colored ink; and Color-Word Page--comprises the words from the first page, printed in the colors from the second page, with the restriction that the word and color do not match.
  • The task is to look at each sheet, and move down the columns, reading words or naming the ink colors, as quickly as possible, within a given time limit.
  • The test yields three scores, and Interference, based on the number of items completed.
