FAQ
- How is the score counted?
- Your score is the streak of correct go and no-go responses in one run.
- What counts as a miss?
- Tapping on red, or failing to tap on green in time, ends the streak.
- Does it get faster?
- Yes. Later signals give you less time, so impulse control matters more.
- Is this a clinical impulse-control test?
- No. It is a short arcade-style challenge, not a medical evaluation.
