Measures the color-word interference tendency, that is the impairment of the reading speed or color recognition due to interfering information.
This Stroop interference test is a sensomotor speed test that measures speed in reading words and naming colors. Afterwards it also measures speed under conditions of color/word interference. The ability to control cognitive interference is usually assessed by means of tasks involving at least two competing information-processing pathways. The task normally requires the respondent to use the less dominant information-processing pathway in the face of interference from the dominant pathway. This test measures both speed in reading words and naming colors and speed under conditions of color/word interference. This also yields information about the respondent’s information processing and attention processes. The test is therefore particularly useful in clinical neuropsychology, but it is also used in safety assessments and sports psychology.
