The Stroop effect shows how automatic reading can interfere with color naming. This session includes a short practice block, then a scored main block mixing congruent and incongruent trials so you can see your interference cost.
How to play
- 1Complete a short practice block to learn the rule.
- 2In each trial, tap the ink color — ignore the written word.
- 3The main block mixes matching and conflicting word–color pairs.
- 4Review congruent vs incongruent speed and your interference cost.
Tips
- • Say the ink color quietly in your head before tapping.
- • Keep accuracy high — wrong answers weaken the interference estimate.
- • Compare set averages over days instead of one lucky round.
