Attention Span Test
Symbols flash on screen. Tap ● only — ignore everything else. 90 seconds. Stay focused.
TAP ● = HIT ✓
MISS ● = -1
TAP ■▲◆ = FALSE ALARM
01 /How to Play
- Targets will appear on screen at random intervals among distractors.
- Tap or click only the target — not the distractors.
- Maintain focus for the full 90-second session.
- Your score is accuracy % combined with reaction consistency.
- Attention lapses (missed targets or false alarms) are tracked separately.
02 /The Science
Sustained attention — the ability to maintain focused alertness over time — is mediated by the right prefrontal cortex and anterior cingulate cortex, with arousal modulation from the locus coeruleus-norepinephrine system. The Continuous Performance Test (CPT), on which this assessment is based, is the gold-standard clinical measure for ADHD screening. Attention performance peaks at ages 20-35 and shows gradual decline thereafter. Individual differences in sustained attention strongly predict academic and professional performance.

03 /Pro Tips
- Minimize external distractions before starting — close other tabs.
- Sit upright — posture affects alertness and prefrontal cortex activity.
- Avoid testing when fatigued — sustained attention is highly sensitive to sleep debt.
- Focus on consistency, not speed — accuracy matters more than reaction time here.
- If you notice your mind wandering, gently refocus without judgment.
