Attention Conflict
Suppress automatic conflicting response
About this trainer
Attention Conflict shows you a stimulus where two cues disagree, and your job is to respond to the one that matters while ignoring the one that distracts. A classic example is a colour word printed in a mismatched ink, like the word RED written in blue, where you must name the ink and not read the word, tapping the correct answer as quickly and accurately as you can.
What it develops
It trains selective attention and response inhibition, the ability to lock onto the relevant feature and override a stronger, more automatic impulse. You are practising the moment of catching yourself before the wrong, habitual answer slips out.
History
The genre grew out of two landmark experiments in experimental psychology. The colour-word version comes from John Ridley Stroop's 1935 interference studies, and the arrow and letter versions descend from the flanker task published by Barbara and Charles Eriksen in 1974. Both became staples of attention research and were later adapted into countless screen-based training games.
Who created it — and when
There is no single inventor of this exact game. It belongs to the conflict-task tradition in cognitive psychology, with the two best-known parents being J. R. Stroop, who published the colour-word interference effect in 1935, and B. A. and C. W. Eriksen, who introduced the flanker task in 1974.
How to train
Slow down just enough to keep errors low, because rushing into mistakes teaches the wrong habit. Name the rule out loud at first ("ink, not word"), keep your eyes on the target feature rather than letting them drift to the distractor, and once accuracy is solid, push for speed on the congruent and incongruent trials alike.
How long to practise
Short and frequent beats long and rare. Five to ten minutes a day, a few days a week, is plenty to build and hold a stable speed, and you will usually see your reaction time settle within the first week or two.
Evidence base
Evidence is strongest for exactly what you would expect — you get measurably faster and more accurate at conflict tasks themselves, and the interference cost shrinks with practice. Claims that this carries over to general attention, self-control in daily life or intelligence are much weaker; controlled studies, including a 2024 trial in children, repeatedly find little near or far transfer, so treat the grand promises with caution.
Recommendations
Chase a low, steady error rate first and let speed follow — a fast run full of mistakes trains exactly the reflex you are trying to suppress.
FAQ
Why do I keep blurting out the wrong answer even when I know the rule?
Because reading a word or following a crowd of arrows is automatic and fast, while applying the rule is deliberate and slower. That gap is the whole point of the exercise, and the practice is what narrows it.
Will this make me more focused in everyday life?
Honestly, probably not in a big way. You will clearly get better at conflict tasks like this one, but the research shows that broad carry-over to real-world focus is weak and unreliable, so enjoy it as targeted practice rather than a cure for distraction.
Should I aim for speed or accuracy?
Accuracy first. Once you are rarely making mistakes, gently push your speed; chasing raw speed before that just trains you to fire off the wrong, automatic response.
Variants
The colour-word Stroop, the arrow or letter flanker with distractors on either side, and number versions where size conflicts with value. Harder modes flip the rule mid-game, add a time limit, or switch which feature is the target so you cannot run on autopilot.
