Stroop Test

Identify the font color of each word, not the word itself.
Use the buttons or number keys 1–4 to respond quickly.

The Stroop task pits automatic reading against controlled color naming. Large gaps between congruent and incongruent reaction times usually mean extra effort to suppress the wrong response — a classic probe of selective attention and inhibition used in research since the 1930s.

FAQ

What does the Stroop test measure?: Primarily selective attention and response inhibition — how well you ignore an automatic process (reading) to name ink color.
Is this a medical test?: This is a self-assessment game, not a medical diagnosis. Talk to a clinician if you have clinical concerns.
