Focus Meter

Master sustained attention with our Focus Meter—a comprehensive assessment measuring your ability to maintain concentration on specific tasks despite distractions and mental fatigue. In our notification-saturated digital age, the capacity to filter noise and sustain focus determines productivity, learning efficiency, and professional success.

How It Works: You'll see a 10×10 grid filled with random digits. Your task is finding and clicking all instances of a specific target digit before it changes every 15 seconds. Across 90 seconds and 6 progressively challenging levels, the visual complexity increases—more numbers, higher density, faster changes—testing how well you sustain focus under mounting cognitive load and time pressure.

The Neuroscience of Sustained Attention: Sustained attention activates your brain's prefrontal cortex (executive control), parietal lobe (attention direction), and locus coeruleus-norepinephrine system (arousal maintenance). Research by Michael Posner shows sustained attention capacity predicts academic achievement, work performance, and resistance to distraction. Unlike selective attention (focusing briefly), sustained attention measures endurance—how long you maintain focus quality before fatigue degrades performance.

Why This Matters: Modern work demands deep focus amid constant interruptions. Can you maintain concentration during long meetings? Study for extended periods? Complete complex tasks requiring sustained mental effort? Filter relevant information from visual noise? Your sustained attention determines productivity in knowledge work, learning retention, creative problem-solving, and any task requiring prolonged concentration. Studies link weak sustained attention to productivity losses, learning difficulties, and vulnerability to distraction.

Professional Applications: Programmers maintain focus during debugging, researchers sustain attention analyzing data, students concentrate during study sessions, medical professionals stay alert during procedures, and knowledge workers resist digital distractions. Your ability to "resist the scroll" directly impacts output quality.

Build Focus Stamina: Complement this with our Cognitive Stamina Test for mental endurance, or try the Stroop Test for interference control.

Performance Insights: Receive accuracy metrics, speed analysis, consistency measurements across the 90-second span, distraction resistance scores, and evidence-based strategies for improving sustained attention through meditation, environment design, and attention training protocols.
