Trail Making (A + B)
A digital Trail Making Test prototype. Trial A measures processing speed; Trial B adds a set-switching demand. Pointer movement is sampled at ~60 Hz alongside click accuracy and reaction times.
Trial A
Numbers in order
You will see 25 circles numbered 1 through 25, scattered across the screen.
Click the circles in order: 1 → 2 → 3 → … → 25, as quickly and accurately as you can.
If you click the wrong circle, it will flash red. Keep going from where you left off.
