Attention & Focus
Visual Search
A grid of similar marks appears. One mark is different. Tap it. Each level adds more items and a smaller difference. A miss ends the run. Short starts easier and stops sooner. Long keeps climbing.

Find the T among the L marks. Each level adds more items. A miss ends the run.
Pick a length
Short is a quick check. Long is the full run. Your best for each is stored on this device.
What this measures
Conjunction search is slower than pop-out. When the target shares colour with some neighbours and shape with others, you must inspect items instead of seeing the odd one for free. That serial scan is how you find a name on a list or a part on a bench. Load (how many items) and similarity (how close the lure is) both raise time. We grow both so the level number compresses search efficiency into one score. A miss ends the climb so guessing is expensive.
Where this shows up in real life
Finding the odd part on a bench, a name on a list, or a changed icon on a toolbar is conjunction search. Strategy beats staring.
How to improve
- Unfocus slightly and let the odd mark pop. Tight staring slows you.
- Sweep in rows so you do not recheck the same cell.
- On later levels the difference is tiny. Slow the sweep, do not tap at random.
- Sit square to the screen. Side angles hide contrast.
Frequently asked questions
What is a good visual search level?
Level 9 is a typical long-run stop. Level 12 and up means you still find the odd item when the grid is dense and the gap is small.
Is this the same as Color Perception?
Color Perception only changes shade. Visual Search changes shape, colour, or both, so you cannot rely on one channel.
Why do I stall on later grids?
The search turns serial. That is expected. Strategy (row sweep) beats raw speed once pop-out dies.
