Stroop Color–Word Interference Test
a three-part test in which (a) color names are read as fast as possible; (b) the colors of bars or other shapes are rapidly named; and, most importantly, (c) color hues are named quickly when used to print the names of other colors (such as the word green printed in the color red). The degree to which the participants are subject to interference by the printed words is a measure of their cognitive flexibility, selective attention, and response inhibition (or disinhibition). In clinical neuropsychology, this test is commonly used to assess dysfunction of the frontal lobes of the brain. Also called Stroop test. See also response conflict. [J. Ridley Stroop (1897–1973), U.S. psychologist]
