Memory
These are the tests where the number is a span — how much you could hold before it slipped. Timing hardware matters less here than it does for speed tests, because the quantity being measured is a count rather than a few hundred milliseconds.
What matters instead is exactly how a trial was scored and when it ended, so that is what these pages state. A span measured one way is not comparable to a span measured another, and we would rather be specific than impressive.
The longest sequence of block positions you can reproduce in order, presented at the rate the board-based research used — and reported as a screen score, not a clinical span.
Open tool →Number Memory TestThe longest string of digits you can hold and recall, presented one per second to match the research the score is compared against.
Open tool →How many words you can keep track of as seen or unseen before you slip.
The largest grid pattern you can reproduce after a brief exposure.
Numbered squares appear and hide; you tap them in order. How far you get.
