Two quick games

  • Reaction time - wait for the screen to turn green, then tap as fast as you can. Five rounds; we average them in milliseconds. Many adults land around 250-300 ms on a phone or mouse.
  • Stroop focus test - colour words appear in the wrong ink (the word RED in blue). Tap the colour of the ink, not the word. Described by J. Ridley Stroop in 1935, it is one of the best-known tests of attention control.
