Memory Tests — Free Online Brain & Cognitive Tests

Working memory is your brain's ability to hold and actively manipulate information in the short term — the cognitive scratchpad that underpins learning, reasoning, and decision-making. It is one of the strongest predictors of academic performance, professional effectiveness, and general fluid intelligence. These memory tests measure different facets of working memory using paradigms drawn from cognitive psychology research.

The Number Memory Test measures your digit span — the longest number sequence you can hold in working memory and accurately recall. The average adult scores 7 ± 2 digits, a finding so robust it is known as Miller's Law. The Sequence Memory Test, inspired by the Simon game, measures visuospatial working memory — your ability to remember sequences of positions rather than verbal items. The Verbal Memory Test measures recognition memory for words, testing how many items you can correctly classify before an error occurs.

The Chimp Test is directly based on the landmark Ayumu study at Kyoto University, which showed chimpanzees outperforming humans in brief-display spatial memory tasks. The Mental Age Test combines multiple cognitive tasks to estimate which age group your performance most closely resembles.

All tests provide immediate results with benchmark context. Run multiple sessions over days and weeks to track how your working memory responds to training and lifestyle changes.
