Braun here from Human Precision. It supports comparison, navigation and ordered recall, but a short browser test samples only part of it. Here is the practical explanation and the limit that matters when using a browser test.
Visual memory is not one system
Visual sensory memory briefly preserves a rich visual trace, visual working memory keeps a smaller amount available for current tasks, and long-term visual memory supports later recognition. Human Precision’s tile-sequence task mainly samples short-term ordered visual recall.
Capacity is limited
Reviews of visual working memory describe strong capacity limits and continuing debate about whether information is stored in a small number of item-like representations or distributed as a flexible resource. Either way, adding more items generally reduces precision or recall.
Order adds another demand
Remembering which tiles appeared is different from reproducing the exact order. Sequence recall requires keeping both identity and position available. Human Precision increases sequence length across rounds and awards partial points before a sequence breaks.
Practice changes the task
Repeated play can improve familiarity, strategy and attention to this specific format. That does not prove a broad increase in memory capacity. Use practice to improve at the activity and compare conditions, not to make a clinical claim.
Try it in context
Take the free visual memory test, then use the Daily Precision test to see how memory compares with reaction, timing, accuracy, focus and rhythm. Continue with selective attention, because attention helps determine what enters memory.
Human Precision provides recreational browser measurements. Device latency, practice, attention and environment affect results. Do not use a score for medical, education, employment, driving or safety decisions.
