Human Benchmark Guides

Reaction time is the gap between a stimulus appearing and your body responding to it. Most adults land near 250 milliseconds on a visual test, while trained gamers and athletes often sit between 180 and 220. These guides cover what counts as a good score at your age, how the percentiles are worked out, why the same person scores differently on different hardware, and which training actually moves the number.

Typing speed and click speed both measure how fast a practised motor skill can be repeated under pressure. The average adult types around 55 words per minute and clicks about 6.5 times per second. These guides break the benchmarks down by skill level, explain exactly how WPM and CPS are calculated, and cover the clicking techniques competitive players use — along with what they cost your hands.

Memory is not one system. Working memory holds a handful of items for seconds, short-term memory a little longer, and recognition memory lets you know a word is familiar without recalling where you saw it. Each memory test on this site probes a different one. These guides explain what your level means, how scores are distributed across real players, and why chimpanzees beat humans at one of them.

Scores respond to training, but not evenly and not forever. Sleep, caffeine, warm-up and screen refresh rate all shift a result before any real skill change happens. These guides separate the interventions with evidence behind them from the ones that only feel productive, and set out a structured week of practice you can actually follow.
