804 STROOP EFFECTS

The Stroop color-word test demonstrates a response-conflict phenomenon. Two versions are available: 1) The "Traditional" version presents color words in congruent or conflicting colors, and uses anagrams of the color words as control stimuli; 2)the "Modified" version, which can be used with either a color or a monochrome monitor, uses the number of stimuli in the display, and asterisks serve as control stimuli.
