Sequence Memory
Remember an increasingly long pattern of button presses.
Aim Trainer
How quickly and accurately can you hit all 30 targets?
Number Memory
Remember the longest sequence of numbers you can.
Verbal Memory
Keep as many distinct words in short-term working memory.
Chimp Test
Test your working memory against primate capabilities.
Visual Memory
Remember an increasingly large spatial board of squares.
Typing Test
Measure how many words per minute (WPM) you type.
Mobile Typing

How Human Benchmark Works
Every test on Human Benchmark is designed with scientific methodology in mind. Take a test, get your result, and see exactly where you stand compared to the global population — all in under 60 seconds.
Take a Cognitive Test
Choose from 9 scientifically designed tests covering reaction speed, working memory, spatial recall, verbal recognition, motor accuracy, and typing fluency. Each test takes 30–90 seconds and uses established psychometric paradigms adapted for the web.
See Your Percentile Ranking
Your score is instantly compared against a global dataset of real test results. See your exact percentile — for example, a 220ms reaction time puts you in the top 15% of all participants worldwide. We use trimmed statistical distributions to exclude outliers and provide honest rankings.
Track Your Improvement
Create a free account to save your scores, track progress across sessions, and compete on the real-time global leaderboard. Research shows that consistent practice on cognitive tasks produces measurable improvement — our platform makes it easy to verify that for yourself.
Why Measure Your Brain with Human Benchmark?
Human Benchmark is the standard online platform for quantifying cognitive reflexes, perceptual speed, and memory capacity. Unlike casual quiz apps, our tests are built on established cognitive science paradigms — the same ones used in university research labs — and calibrated against a continuously growing global dataset.
Reaction & Motor Speed
Test how quickly your central nervous system processes visual stimuli through the Reaction Time Test and Aim Trainer. The Reaction Time Test measures simple visual reaction time — the interval between seeing a green screen and clicking — averaging five attempts to reduce noise. The Aim Trainer quantifies hand-eye coordination using Fitts's Law principles. Together, these tests map the speed of your entire perceptual-motor pathway, from photon hitting retina to finger depressing mouse button.
Working & Spatial Memory
Explore the limits of your short-term recall with Sequence Memory, Visual Memory, Number Memory, and the Chimp Test. These tests are based on Baddeley's Working Memory Model and decades of cognitive psychology research. The average adult can hold 7 ± 2 items in working memory (Miller's Law). Our tests find your personal ceiling and track how it changes with practice, sleep, and time of day.
Global Percentile Rankings
Compare your personal bests against thousands of players worldwide on real-time leaderboards. Every score is placed on a percentile curve built from actual test data collected globally. When you see that your reaction time is in the 80th percentile, it means you outperformed 80% of all recorded attempts. Sync your scorecard across all your devices with cloud backups.

What is Reaction Time? The Biological Blueprint of Human Reflexes
Human reaction time is not instantaneous—it is a sequence of biological handoffs across photoreceptors, thalamic relays, motor planning areas, and neuromuscular junctions taking 215–260ms in healthy adults.
Read articleWorking Memory Explained: The Cognitive Engine of Human Intelligence
Working memory is not passive short-term storage—it is an active mental workspace governed by the dorsolateral prefrontal cortex that coordinates perception, reasoning, and decision-making.
Read articleThe Stroop Effect: Cognitive Interference and the Anterior Cingulate Cortex
Reading a word is so thoroughly automated that when the word "RED" is printed in blue ink, your anterior cingulate cortex must expend 150–250ms of executive inhibitory effort to override the automatic reading impulse.

Decision time does not increase linearly with the number of choices; it increases logarithmically in direct proportion to the information entropy (in bits) of the decision.

Human Benchmark is a premier collection of online cognitive, perceptual, and motor performance tests. It accurately measures essential human capabilities like visual reaction time, short-term working memory, verbal recall, target aim, and typing speed.
The global median reaction time for human benchmark tests is approximately 273–284 milliseconds. Top 10% performers consistently achieve reaction times below 200 ms, while competitive gamers and athletes can record reflex speeds in the 150–180 ms range.
The Chimp Test evaluates spatial working memory. Based on landmark Kyoto University cognitive research by Tetsuro Matsuzawa showing young chimpanzees outperforming adult humans at photographic number recall, the test flashes numbers on screen and asks you to tap them in numerical order once hidden.
Yes! All Human Benchmark tests are 100% free with no downloads required. The site includes dedicated mobile-friendly tests like the Mobile Typing Test and full responsive support across phones, tablets, and desktop browsers.
