Colour Conflict

Name the ink colour of a word, not the word itself. Trains the ability to keep the relevant feature in front and push a stronger habit aside.

How to play Colour Conflict

Selective attention

Choose the ink colour the word is printed in. Ignore what the word says.

  • A colour word appears, printed in a colour of its own.
  • Choose the ink colour, never the word meaning.
  • The buttons stay in the same positions for the whole set.

What Colour Conflict measures

A Stroop task. Reading is close to automatic, so a mismatched colour word competes with naming the ink. The gap between mismatched and matched trials is the interference cost.

What does the score mean?

Your score describes how you did on this task, on this day, at this difficulty. It is not an IQ score, a percentile or a medical measure. The headline number here is interference cost. Scores compare you with your own earlier sets, never with other people. Read more on what the exercises measure.
