Sequence Memory
A clinical assessment of your sequential working memory and pattern recognition. Watch the grid light up — then repeat the exact sequence. Each round adds one more step.
Sequential Pattern Recognition
Watch the sequence · Repeat it back · Go as long as you can
01 /How to Play
- Click 'Begin Protocol' to start the assessment.
- Watch the grid — squares will light up in a sequence.
- After the sequence finishes, click the squares in the exact same order.
- Each correct round adds one more step to the sequence.
- One wrong click ends the test — your score is the longest sequence you completed.
02 /The Science
Sequential pattern memory — the ability to encode, retain, and reproduce ordered spatial information — relies on a distributed neural network involving the hippocampus, dorsolateral prefrontal cortex, and the supplementary motor area. This capacity is distinct from simple digit span and is more closely linked to procedural learning and implicit sequence acquisition. Research in cognitive neuroscience demonstrates that sequence memory underlies complex skills including musical performance, surgical technique, and programming. The visuospatial sketchpad, a component of Baddeley's working memory model, is the primary system engaged during this task. Sequence length at which performance breaks down is a reliable predictor of general fluid intelligence and attentional control.
03 /Pro Tips
- Verbalize the positions as you watch — 'top-left, center, bottom-right' creates a dual-coding memory trace.
- Chunk the sequence into groups of 3 once it exceeds 5 steps, treating each chunk as a single unit.
- Track the rhythm of the highlights — sequences have timing patterns your motor memory can exploit.
- Avoid blinking during the display phase — even a 200ms blink can cause you to miss a flash.
- After each round, mentally replay the full sequence before the next display begins to reinforce encoding.
