Focus
Focus tests measure how quickly and precisely you can direct your attention — like finding the one symbol that's different in a grid of near-identical distractors. Your score reflects both scanning speed and discipline: wrong clicks cost accuracy, so guessing doesn't pay.
Tests in Focus
Visual Search Test
Free visual search test. Find the odd symbol hidden in a grid of look-alikes across five rounds — measuring scanning speed and click accuracy.
Stroop Test
Name the ink color, not the word — the classic interference test of focus and cognitive control, scored on speed and accuracy.
Go/No-Go Test
Free go/no-go test. React fast to green, hold back on red — the classic impulse-control task, scored on go reaction time and inhibition errors.
Why It Matters
Visual search is what you do when proofreading a document, scanning a spreadsheet for the broken number, reading a dashboard, or finding a name in a list. Faster, more accurate scanning means fewer misses and less rework. Attention is also trainable: deliberate search practice improves how efficiently your eyes move and how well you ignore distractors.
