Reflex TapStop the bar at the center - one tap, pure reflex 
Typing Speed Test60 seconds. What's your WPM? Numbered squares appear on a grid. The moment you click the first one, all the numbers vanish and you have to click the rest in order from memory. Every round adds another square. It is a test of working memory under a very specific condition: you get one brief look and no chance to rehearse.
The name comes from research at the Primate Research Institute at Kyoto University, where young chimpanzees were tested on almost exactly this task and performed better than human adults, holding accurate spatial layouts from exposures of a fraction of a second. The usual explanation is that humans trade some of that immediate photographic capacity for language, though it remains an area of genuine debate rather than settled fact.
Most people fail somewhere between 8 and 10 squares. Getting to 11 puts you in the top quarter, 13 in the top fifteen percent, and beyond 15 is rare. The chimpanzees in the Kyoto studies handled around nine reliably at exposures far shorter than the ones here, which is the comparison that makes the test uncomfortable.
The Chimp Test is the hardest of the three memory tests here because there is no rehearsal window. Sequence Memory shows you the order over time, and Number Memory lets you say the digits to yourself. Comparing all three tells you whether your memory leans spatial or verbal. Reaction Time and Aim Trainer round out the set with speed rather than recall.
It is modelled on research at the Primate Research Institute at Kyoto University, where young chimpanzees were tested on a very similar task and outperformed human adults at recalling the positions of numbers from a brief glimpse.
On this specific type of task, young chimpanzees have been shown to perform remarkably well, holding accurate layouts from very short exposures. It is a narrow ability rather than general memory superiority, and the reasons behind it are still debated.
Most people fail between 8 and 10 squares. Reaching 11 puts you in the top quarter, 13 in the top fifteen percent, and past 15 is rare.
As long as you like, because nothing hides until you click number one. Most people click too quickly and lose the round before it starts.
Yes. Every cleared round adds one more numbered square to the grid.
