The sequence memory test measures visuospatial working memory — your brain's ability to temporarily hold and recall the order of visual events. A grid of squares flashes in a specific sequence. Your job: remember the order and click them back. Each correct round adds one more square to the sequence. Most people max out at 6–9 squares.
This test is fundamentally different from the number memory test (digit span), which measures verbal working memory. Sequence memory tests visuospatial memory — the same system you use to remember where you parked your car, navigate a new city, or track enemy positions in a video game.

What Sequence Memory Actually Measures
Sequence memory tests the visuospatial sketchpad — one component of Alan Baddeley's influential working memory model. Unlike the phonological loop (digit span), which stores verbal information through subvocal rehearsal, the visuospatial sketchpad holds visual and spatial information temporarily. It has limited capacity — roughly 3–4 objects for most people — and the contents decay within seconds unless actively maintained.
In the test, you are using both spatial memory (remembering where each square is) and temporal order memory (remembering when each square lit up). These are distinct sub-systems in the brain: spatial memory relies heavily on the hippocampus and parietal cortex, while temporal order memory depends more on the prefrontal cortex.
Typical Sequence Memory Scores
- 3–5 squares: Below average. Common with divided attention or fatigue. Consistent scores in this range may indicate weak visuospatial working memory — but this is highly trainable.
- 6–8 squares: Average range for healthy adults. Most people land here on their first attempt.
- 9–12 squares: Above average. Good visuospatial working memory. Common in people who play action video games or do visually demanding work (design, engineering).
- 13–15+ squares: Exceptional. Top performers use chunking strategies — grouping squares into patterns rather than remembering individual positions.
How to Improve Sequence Memory
Unlike digit span, which has a relatively hard ceiling, visuospatial sequence memory shows more plasticity with training. Three strategies help:
- Chunking. Group adjacent squares into shapes. Instead of remembering "top-left, top-middle, center" as three individual squares, remember it as an L-shape. This compresses 3+ items into one chunk.
- Verbal encoding. Assign numbers or labels to grid positions and subvocalize the sequence: "1, 5, 3, 2." This offloads some of the memory demand from the visuospatial sketchpad to the phonological loop — using both working memory systems instead of one.
- Daily practice. Like all working memory tasks, frequency beats duration. 5 minutes on the sequence memory test every day for two weeks typically adds 2–3 squares to your max. The improvement is specific to the task, but the cognitive strategy of chunking generalizes to other visual memory challenges.
