Measure visual search efficiency and signal detection in visual noise
Click the target (a polygon slightly different from a circle). Distractors are circles of the same color. The task lasts 30 seconds. After each click, the layout changes.
Press Start. Then click the target as fast as you can.
Your score reflects how well you keep clean hits while staying fast enough to find many targets in a short run. The most useful comparison is your own trend on the same device, not one isolated best attempt. This is a self-tracking task, not a clinical assessment.
This task samples visual filtering, selective attention, and quick target selection. You must scan a cluttered field, ignore distractors, and commit to the one item that breaks the pattern.
Repeated practice can support faster target detection, steadier visual search, and cleaner decisions under mild time pressure. If you want a broader attention routine, this pairs naturally with Flanker or Stroop.
Difficulty level, screen size, pointer precision, fatigue, and rushing all matter here. Easy uses fewer distractors and a clearer target, while harder settings increase clutter and make the target more visually ambiguous.
Visual filtering tasks are widely used in cognitive psychology because they stress target selection in the presence of distractors. That is why they fit well with articles on attention and distractions, practical guides on tracking cognitive progress, and open-access work on visual attention in search tasks.
At higher difficulty the target is more circle-like. Use a brief confirmation glance before you click.
Input latency, screen size, and pointer precision affect both speed and accuracy.
Hits drive points the most, but misses reduce your score. Aim for clean hits first, then push speed.

For training and self-tracking only; not a clinical or diagnostic instrument.
