Why this drill matters for sustained attention
- It trains you to keep focus steady while scanning crowded visual information.
- It reduces careless misses by forcing consistent attention across every row and column.
- It builds resistance to distraction because you must ignore non-target items repeatedly.
- It improves mental endurance, which helps you stay accurate under time pressure.
