Focus & Concentration Test
A clinical-grade Continuous Performance Test (CPT). Measure your sustained attention, reaction speed, and impulsivity over a 50-stimulus set.
🧠 Focus Assessment
Stimuli will flash briefly at random intervals. Press SPACEBAR (or tap the screen) ONLY when you see the Target. Ignore everything else.
What is a Continuous Performance Test (CPT)?
The Continuous Performance Test (CPT) is a standard psychological assessment tool used to measure a person's sustained attention, vigilance, and impulse control. Unlike simple reaction time tests, a CPT requires you to maintain focus over an extended period and make rapid "Go/No-Go" decisions.
In clinical settings, variations of this test (like the TOVA or Conners CPT) are often used as supplementary tools in the assessment of Attention Deficit Hyperactivity Disorder (ADHD) and other neurological conditions.
Understanding Your Metrics
To truly understand your focus profile, it is critical to look beyond just your overall score. The breakdown reveals exactly how your attention system is functioning:
| Metric | Meaning | High Values Indicate |
|---|---|---|
| Omissions (Misses) | Failing to click when the target appears. | Inattention or fading vigilance. Your mind wandered during the test. |
| Commissions (False Alarms) | Clicking when a non-target appears. | Impulsivity or hyper-anticipation. A failure of inhibitory control. |
| RT Variability (StdDev) | The standard deviation of your reaction times. Are your clicks consistently the same speed? | Erratic Focus. A high standard deviation means you are zoning in and out, rather than maintaining a steady state of flow. |
Focus Scoring & Ranks
Your overall Focus Score (0-100) is a composite metric that heavily penalizes Omissions and Commissions, while rewarding fast, consistent reaction times.
| Rank | Typical Profile |
|---|---|
| Zen Master (95-100) | Zero errors, highly consistent reaction times (low StdDev), deeply focused. |
| Sharpshooter (85-94) | 1-2 minor errors, strong inhibitory control, steady speed. |
| Operative (70-84) | Average focus. A few impulsive clicks or slight mind-wandering near the end. |
| Drifter (<70) | High omissions (zoning out) or high commissions (trigger-happy). |
Applications in Esports & Gaming
In competitive gaming (like CS2, Valorant, or League of Legends), raw reaction speed is less important than Inhibitory Control and Vigilance. A high Commission rate translates to shooting teammates or revealing your position too early. A high RT Variability translates to inconsistent performance — playing like a pro in one round, and throwing the next.
Frequently Asked Questions
Why are the intervals between flashes random?
If the interval was fixed (e.g., exactly 1 second), your brain would adapt to the rhythm and anticipate the timing, turning it into a rhythm test rather than an attention test. Random intervals force your brain to remain continuously vigilant.
Is this a diagnostic test for ADHD?
No. While this tool uses the exact same mechanics as clinical CPTs (like the TOVA or Conners CPT), it is for educational and self-improvement purposes only. It cannot be used to diagnose ADHD or any medical condition. Always consult a healthcare professional for diagnosis.
What is a "good" RT Variability?
A Standard Deviation (StdDev) under 50ms is excellent and indicates highly consistent, machine-like focus. Anything above 100ms indicates your attention is fluctuating significantly.
How can I improve my score?
Practice "Focus Stacking." Before starting, take three deep breaths, fixate your eyes slightly above the center of the screen, and actively tell yourself to inhibit the urge to click until you identify the target. Regular meditation has also been shown to improve CPT scores.
