Go/No-Go Test
Most signals say go — a green pad you should hit as fast as you can. A few say stop. The catch is that the faster you commit to reacting, the harder it is to hold back, and pressing on red is exactly the slip this test measures. It's the classic response-inhibition task from attention research, punishing both hesitation (slow reactions, missed greens) and impulsiveness (pressing on red). Runs below 90% accuracy aren't scored, so mashing every signal won't earn you a time.
No personal best yet — finish a run to set one.
Green means press — as fast as you can. Red means do nothing and let it pass. 36 signals, short random pauses between them.
