A small laboratory for curious minds.
Playful tasks can help us explore attention and response. They cannot diagnose brain damage or determine whether your brain health is declining.
Experiment 01
The Copper Signal
A five-round response-time activity. Tap the large field only after it changes colour. It works with a mouse, touch, or keyboard.
Before you play
Reaction time varies with the device, sleep, stress, medication, practice, vision, hearing, movement, and many other factors. This is a playful demonstration—not a cognitive test.
Round 1 / 5Press start, then wait for the field to turn copper.
