Go/No-Go

How to Play

A shape appears on screen. If it's a circle (GO), press the button or Spacebar as fast as you can. If it's a square (NO-GO), don't press anything. This tests your brain's ability to inhibit impulses.

Tips

• Pay attention to shape, not color — both use the same colors
• False alarms (responding to squares) hurt your score more than misses
• Stay relaxed and focused — tension makes inhibition harder
