Paradigm overview
The Stroop Color-Word Test is a classic measure of cognitive inhibition and the automaticity of reading. Participants see color words (RED, GREEN, BLUE, YELLOW) displayed in colored ink and must identify the ink color while suppressing the automatic tendency to read the word. On congruent trials, the word matches the ink color (RED in red ink). On incongruent trials, they conflict (RED in blue ink). Neutral trials use non-color words (XXXX) in colored ink.
The Stroop effect (incongruent RT minus congruent RT) reflects the processing cost of inhibiting the overlearned reading response. The interference score normalizes this cost against the neutral baseline, providing a ratio-based measure of executive control efficiency.
The Stroop test engages the anterior cingulate cortex for conflict detection and the left inferior frontal gyrus for response inhibition. It is one of the most widely used neuropsychological tests, with over 700 published studies establishing its sensitivity to frontal lobe dysfunction.
Key scoring outputs
Congruent RT
msAverage RT when word meaning matches ink color.
Lower is better
Incongruent RT
msAverage RT when word meaning conflicts with ink color.
Lower is better
Stroop Effect
msIncongruent RT minus congruent RT. Primary measure of interference cost from automaticity.
Lower is better
Interference Score
ratio(Incongruent RT - Neutral RT) / Neutral RT. Ratio-based measure controlling for baseline processing speed.
Lower is better
Congruent Accuracy
proportionProportion correct on congruent trials.
Higher is better
Incongruent Accuracy
proportionProportion correct on incongruent trials. More sensitive than congruent accuracy.
Higher is better
