What it practises
- Attention & focus: Picking out what matters, ignoring distractions and splitting attention between two things.
- Decision-making & reaction: Reading a fast-changing scene and choosing a move under time pressure.
Games reward short bursts of attention. Longer focus is covered separately under Sustained focus.
Quick lesson: Searching a busy scene
Something with a unique colour or shape “pops out” at once, however busy the scene is. When it shares each feature with the things around it, you have to check items one by one, so more items take longer.
Check question
Which target is quickest to find among 20 blue circles?
- A blue circle
- A red circle
- A slightly bigger blue circle
- A blue circle with a dot
Answer: A red circle. Only the red one has a feature nothing else has, so it pops out.
