Speed Match
Cards fly past. Same as the one before, or different? You have 45 seconds and a combo meter.
How to play
- Remember the first card
- Every card after: tap Match or Different vs the previous one
- Correct answers build a combo multiplier
- Mistakes reset the combo and cost points
What it trains
Speed. This is a continuous 1-back: the lightest possible memory load, refreshed every second. What it actually trains is updating speed, the rhythm of writing a new item over an old one without losing either. Speed of processing is one of the abilities that ages earliest, which is why fast comparison tasks appear in nearly every cognitive battery.
Salthouse, 1996, processing-speed theory.
One honest tip
Answer on rhythm, not on certainty. At one item of load, hesitation is the only real enemy.
