How is this different from Number Memory?

Number Memory shows digits one at a time; here the whole number flashes at once for one second, testing a slightly different encoding.

The brief exposure prevents sub-vocal rehearsal from inflating span, isolating transient encoding.

A span of 6 is around the typical range; 8 is exceptional per our estimated norms.

이 테스트가 측정하는 것

Transient Number Memory measures how many digits you can hold and reproduce after a one-second flash. It's a research-grounded short-term memory span task.

작동 방식

A number flashes on screen for one second, then disappears. Type it exactly. The length grows when you're right and shrinks when you're wrong. Two misses in a row end the test.

결과 계산 방법

Your primary score is the maximum span you reproduced correctly (higher is better), estimated against population norms.

정확도와 한계

Attention and input method affect results. This is a research-grounded task (Evidence C), not a clinical evaluation.
