Orbital FocusAttention Span Test
Try a short sustained-response task, then review your misses, false alarms, and response consistency. The result describes one run and is not a diagnosis.
Respond to every digit except 3
- Place one finger on the Space bar, or use the Respond button on touch devices.
- Respond once when any digit except 3 appears.
- Withhold your response when the digit is 3. The task lasts 2 minutes 30 seconds.
Choose a quiet moment. Switching tabs stops the run because hidden-tab timing would make the result misleading.
This visual, timed task does not provide an equivalent screen-reader measurement.

- 0
- False alarms on 3

The on-task score weights overall accuracy at 60%, correct withholding at 25%, and response-time consistency at 15%. It is a summary of this run, not a percentile.
What this task measures
This is a browser go/no-go task. You make frequent responses to ordinary digits and withhold the response when 3 appears. The result reports correct responses, misses, false alarms, median response time, and consistency across one 2.5-minute run. Those measurements can show that your performance changed during this task today.
What the score does not mean
The on-task score is not a clinical attention-span test, diagnosis, IQ score, age norm, or comparison with other people. It has no validated cutoff for ADHD, anxiety, sleep loss, or any medical condition. A keyboard, touch screen, display lag, unfamiliar instructions, noise, caffeine, sleep, pain, and simple luck can all move the result.
Use repeated runs only as a personal observation under similar conditions. A lower score is not proof that your attention span is damaged, and a high score does not rule out a real difficulty. If attention problems interfere with school, work, driving, safety, or daily life, discuss them with a qualified health professional instead of relying on this page.
How to get a cleaner personal comparison
- Use the same device and input method each time.
- Run the task in a quiet place with the tab visible.
- Write down sleep, time of day, and interruptions before comparing runs.
- Compare raw misses and false alarms, not only the combined score.
This is a visual timed task. Screen-reader timing does not provide an equivalent measurement, so the page does not claim that an audio-assisted run is comparable.
Take the result as a cue, not a label.
Choose one realistic duration, remove one distraction, and see how the next mission feels.

How to Fix Your Attention SpanAttention is not a single score you repair once. It is a behavior you can make easier with fewer cues, smaller starts, and blocks that grow only when you are ready.
The Pomodoro TechniqueThe classic cycle is simple: choose a task, work for 25 minutes, break for 5, and take a longer break after four rounds. The useful part is the visible finish line, not obedience to one sacred number.
