Visual Memory Test
A spread of units flashes for under a second, blinks away, and comes back with exactly ONE unit changed. Click the impostor. Fields grow from 6 to 12 units — bigger fields are worth more.

What's a good score?
90%+ weighted — Exceptional — you photograph the field.
75–90% — Strong visual short-term memory.
60–75% — Typical for a first session.
< 60% — Common when tired — visual memory drops fast with fatigue.
What this test measures
This is a change-detection task — the lab’s standard probe of visual short-term memory, the buffer that holds “what the screen just looked like.” Most people reliably hold around 3–4 objects; the growing field sizes push past that ceiling on purpose.
For gamers, it’s the snapshot skill: the minimap glance you reconstruct two seconds later when you realize someone was missing.
Questions players ask
How many objects can visual memory hold?
The classic finding is 3–4 objects for most adults. Scores above that on larger fields usually reflect chunking strategies — grouping the field into patterns rather than storing units one by one.
Is visual memory trainable?
Performance on change-detection tasks improves with practice, and strategies like chunking transfer across similar tasks. As with all cognitive training, improvement is measured on the trained skills themselves.
Why do bigger fields count for more?
Catching a change in a 12-unit field is much harder than in a 6-unit field, so the score weights accuracy by field size — the same logic labs use for set-size effects.
