About this test: This comprehensive assessment measures four core aspects of attention — how well you filter distractions, hold focus over time, control impulses, and scan visual detail.

Part 1 — Selective Attention (12 trials):

A color word appears (e.g. RED) printed in a colored ink
Ignore the word's meaning — tap the button matching the INK COLOR
Respond before the timer runs out; based on the classic Stroop task

Part 2 — Sustained Attention (40 digits):

Digits 1–9 flash one at a time
Tap the zone (or press Space) for every digit EXCEPT 3
When 3 appears, withhold your response; based on the SART format

Part 3 — Impulse Control (20 signals):

Green ● = tap (or press Space) as fast as you can while it is visible
Red ✗ = do NOT respond — resist the urge
Based on the classic Go/No-Go task

Part 4 — Visual Scanning (12 rounds):

Two target symbols are shown with a row of symbols below
Choose YES if either target appears in the row, NO if not
Both speed and accuracy count

Scoring: Your final Attention Score* combines speed and accuracy across all four sections. Impulse-control errors (responding when you should hold back) weigh heavily, because inhibition failures are the clearest sign of attention lapses. Each section also gets an individual rating with context.

*Attention Score is our own scoring system based on your test performance — it is not a standardized or clinically validated measure, and it cannot diagnose ADHD or any other condition.
