Test your selective attention by finding all the target symbols hidden among distractions — as fast as you can.
A grid of colorful symbols will appear. Find and click all the blue circles 🔵 as fast as possible while ignoring the distractions. Speed and accuracy both count.
A focus test — also called an attention or concentration test — measures your ability to selectively concentrate on relevant information while filtering out distractions. This cognitive skill, known as selective attention, is essential for productivity, learning, driving, and almost every complex task you perform daily.
Our focus test uses a visual search task. You're asked to find specific target symbols hidden among many similar-looking distractors. The faster and more accurately you locate the targets, the stronger your selective attention and visual processing.
When you start the test, a grid filled with colorful symbols appears. Among the distractor symbols are several blue circles — your targets. Your job is to click every blue circle as quickly as possible. We track how long it takes you to find them all and penalize incorrect clicks. The result is a focus score reflecting your speed and precision.
This task is based on the visual search paradigm widely used in attention research. It challenges your brain to suppress irrelevant information (the distractors) while actively scanning for targets — a core function of the brain's attention network.
Attention is highly sensitive to your mental and physical state. Lack of sleep, stress, hunger, and digital fatigue all reduce focus. Background noise and multitasking are especially damaging — research consistently shows that switching between tasks significantly lowers attention performance.
Focus can be strengthened through practice. Mindfulness meditation, regular breaks, reducing screen distractions, and attention-training exercises have all been shown to improve sustained and selective attention over time.
