The Visual Processing Speed Challenge

Balloons appear after an unpredictable pause. One is red and carries a ring mark — that is your target. The rest are blue distractors. Tap the target as fast as you can. More distractors appear as you go.

• One practice round first. It is not scored.
• Then five scored rounds, roughly 30 seconds in total.
• Tapping before the balloons appear restarts that round.
• Tapping a blue balloon is recorded, and the clock keeps running.
