What to test in Memory
The memory category includes spatial recall, ordered sequences, digit recall, and word recognition. Those tasks use different kinds of information, so one score does not summarize “memory” as a whole; the useful comparison is how your own results change within each challenge.
Visual Memory
Recall highlighted positions after a grid disappears.
Sequence Memory
Repeat an increasingly long ordered pattern.
Number Memory
Recall digit strings that grow after correct rounds.
Word Memory
Recognize whether a word is new or has appeared before.
How to compare your results
Use the same difficulty and avoid external notes or screenshots. Device size can change spatial tasks, while distraction and pacing can change recognition and sequence performance.
All Ruth Performance Lab scores stay in local browser storage. These challenges are recreational personal-performance tools, not medical, psychological, educational, or employment assessments.
Compete against your own baseline
These challenges are designed for repeat play. Device, browser and input hardware can affect results, so the most useful comparison is your own score history on a consistent setup.
All scores are stored locally in your browser. They are recreational measures, not medical, psychological or diagnostic tests.
