What it trains
This sprint leans on the scanning skills you use to find one thing in a busy scene.
- Visual search speed
- Selective attention
- Resisting visual clutter
Honest note: you mostly get faster at this exact task, and the score is not an IQ measure or a diagnosis.
Tips to spot more
A steady scanning pattern beats random darting.
- Sweep left to right, row by row
- Let the different shape of the T pop out rather than checking each cell
- Stay calm - rushing makes you miss the obvious ones
The honest way to read your score
Your best count is a personal benchmark, not a ranking against anyone else. Expect it to wobble day to day, and only compare yourself to your own past runs.
