Focus & Concentration

Exercises targeting sustained attention, selective focus, cognitive control, and visual processing speed. Use these during or before high-focus work sessions.

Stroop Test
A color word appears in a mismatched ink color. Click the ink color — not the word itself. Tests cognitive control and response inhibition.
Cognitive control 60 sec
Schulte Table
Numbers are scattered randomly across a grid. Click them in ascending order as fast as possible. Trains attention scanning and processing speed.
Attention scanning Timed
Visual Search
A grid of identical characters appears with one subtle impostor. Find and click it before time runs out. Gets faster each round.
Selective attention 12 rounds
Focus Hold
Keep your cursor locked on a tiny center dot while distractions fill the screen. Score is based on how consistently you hold focus.
Sustained focus 60 sec
Attention Span
A sequence of colored dots flashes one at a time. Decide whether a target color was in the sequence. Sequence length grows with accuracy.
Working memory 20 rounds
Best results: Do these in a quiet environment without other distractions. The goal is to tax your attentional system intentionally — that's where the training effect comes from.
