Colour-Word Challenge

Test how well your brain handles conflicting information by identifying ink colors rather than reading color words.

About This Game

The Colour-Word Challenge is based on the Stroop Effect — one of the most replicated findings in cognitive psychology. Reading is an automatic process that interferes with the more deliberate task of naming ink colors.

What It Trains

• Inhibitory control: Suppressing automatic responses (reading) in favor of deliberate ones (naming color)
• Cognitive flexibility: Switching between competing mental tasks
• Selective attention: Focusing on relevant features while ignoring distracting ones

The Science

The Stroop Effect was first described by John Ridley Stroop in 1935. It remains a standard tool in neuropsychological assessment and research on executive function and attention. The interference effect is reduced in people with strong inhibitory control.
