Visual Search Test: Free Online Attention Test
Visual search is a core attention paradigm from cognitive science: find a single target hidden among distractors, as fast as you can. Playing it online practices and measures scanning speed and sustained attention. Free to play, scored instantly, no sign-up required.
A quiet round of Visual Search — Basic. When you start, everything else fades — just you and the task.
No sign-up needed. Press Esc to exit anytime.
Tip
It is never going to pop out. The target and the distractors are built from the same two strokes — a T and an L differ only in where the strokes meet — and every item is rotated at random, so no single feature separates them. Waiting for the T to announce itself burns the opening second of every round; start sweeping straight away.
Everything here is free
Every test, every difficulty, no limit and no account. If it is useful to you, you can chip in — entirely optional, and nothing changes either way.
Visual Search: what it is and where it comes from
What is a visual search task? Visual search is the paradigm behind Treisman and Gelade's (1980) feature-integration theory: you find one target among distractors, and the time it takes shows whether the target pops out on a single feature or has to be checked item by item. Focani's free browser version runs 8 rounds per session and needs no sign-up.

| Core dependent metrics | Completion time (s) · False alarms (commission errors) |
| Standard stimulus / trial parameters | Set size is varied systematically across many trials so that a search slope — milliseconds added per additional item — can be estimated. |
| This version | Basic — 8 rounds · Dense — 10 rounds |
| Browser adaptation notes | Set size is fixed within each difficulty here, so no slope is produced. The classic dependent variable of the paradigm is therefore not measured at all. |

How to play
- A field of items appears — mostly distractors and one target.
- Scan the field and click the target as quickly as you can.
- Avoid clicking distractors — misses lower your accuracy.
- Finish all rounds to see your time, accuracy, and score.
Visual Search tips
Ways to play it better — each one comes from how this version actually scores, not from general advice about concentration.
It is never going to pop out
The target and the distractors are built from the same two strokes — a T and an L differ only in where the strokes meet — and every item is rotated at random, so no single feature separates them. Waiting for the T to announce itself burns the opening second of every round; start sweeping straight away.
One sweep pattern, every round
The target lands anywhere with equal probability, so no corner has earned a second look before the rest of the field has had a first one. A fixed path costs less than re-checking places you have already been.
One wrong tap is unusually expensive
Accuracy is scored out of the rounds, not out of the items you looked at. On Basic — eight rounds — a single wrong tap takes eleven percent off the multiplier, close to three times what the same mistake costs on the Schulte Table's 5×5, where it is spread across 25 numbers. This is the one test here where being sure pays for itself.
One caveat worth knowing: a change of strategy moves your score for reasons that have nothing to do with attention. Your dashboard reads each session against your own recent ones, so if you adopt something from this list, give it a few sessions before reading anything into the trend.
Frequently asked questions
What is a visual search test?+
It's a task where you find a target among distractors. Researchers use it to study how attention scans a scene; here it's a quick way to train scanning speed and sustained attention.
What does visual search train?+
Scanning efficiency and the ability to stay focused while filtering out irrelevant items — useful whenever you need to spot the important thing in a busy field.
Is it free to play?+
Yes. Play and see your score with no sign-up; an account adds saved history and the leaderboard.
Is visual search testing related to peripheral vision training?+
They overlap. A visual search test measures how efficiently you scan a field, which draws on peripheral vision — you spot candidates in the periphery before fixating on them. If you want a drill that leans harder on peripheral vision specifically, try the Schulte Table, where you keep your gaze centered and locate numbers around it.
Where this fits
- Processing Speed Test — Target detection among distractors. Same eyes, different bottleneck: how efficiently you reject things that are not the target.
- Mind Wandering — Repeated rounds over a couple of minutes. Watch whether your later rounds slow down relative to your first ones.
