What it practises
- Memory & thinking speed: Holding patterns, sequences and positions in mind while the game moves on.
- Decision-making & reaction: Reading a fast-changing scene and choosing a move under time pressure.
Practising a memory task makes you better at that task. We make no claim about memory in daily life.
Quick lesson: Learning a code
At first you look up every symbol in the key. With practice you remember the pairs and stop looking, which is quicker. Learning a few pairs at a time works better than all at once.
Check question
Why do people get faster at a symbol code as they play?
- The symbols get simpler
- The key gets bigger
- They remember pairs instead of looking
- The clock slows down
Answer: They remember pairs instead of looking. Remembering a pair is quicker than finding it in the key.
