Test Your Memory: What Normal Scores Look Like

Baselines first, bragging later. Here is what typical adult scores look like on the classic tests, so your numbers mean something.

Digit span: 6 to 7 forward

Most adults recall 6 or 7 digits forward. Below 5 on a calm attempt is worth noting; 8 or more puts you in the upper range. Run the digit span test a few times and take your median, not your best; single runs are noisy.

Backward span: about 2 less

Typing numbers in reverse usually lands 2 digits under your forward span, so 4 to 5 is normal. A big forward-backward gap mostly means the reordering is eating your capacity, which is exactly what backward span exists to measure.

Spatial span: 5 to 6

On Corsi-style tasks people typically reproduce sequences of 5 to 6 positions. Path Trace runs a friendlier connected version, so scores there trend slightly higher; treat 7 or more steps as strong.

The chimp test: humble yourself first

Fresh players usually clear 5 to 7 numbers before the masking beats them. The chimpanzee who made this task famous handled 9 masked numerals at speed. Humans reach that with practice, which is the fun of it. Take the chimp test.

Reading your own results honestly

Measure on your median of 3 runs, rested. Tired scores measure tiredness.
Compare you-today with you-last-week, not with strangers online.
Expect fast early gains; those are strategy discoveries, not new hardware. The slower climb after week one is the real training signal.
One bad day means nothing. Trends over 5 or more sessions mean something.

A fair daily measurement

The daily test gives everyone on Earth the same three boards each day, so day-to-day comparison is clean: same tests, same difficulty, only you vary. Two weeks of daily results is enough to see a real trend line.

Span baselines: Wechsler norms; Corsi span: Berch et al., 1998; chimp comparison: Inoue and Matsuzawa, 2007.
