Reaction Test Pro

Play Reaction Test Pro free online. A three-part reaction battery: simple, choice and go/no-go reaction times.

Go beyond a single reaction test. Reaction Test Pro measures three different skills: simple reaction (respond to green), choice reaction (press the side the arrow points to) and inhibition with go/no-go (respond to green but hold still for red). You get your average time and accuracy for each part.

How to play Reaction Test Pro

Objective: Respond quickly and accurately across all three parts.

  1. Part 1 — Simple: wait for the panel to turn green, then respond immediately.
  2. Part 2 — Choice: an arrow appears; respond on the side it points to.
  3. Part 3 — Go / No-go: respond to GO (green) but do nothing for STOP (red).
  4. Responding before the stimulus appears always counts as a mistake.

Scoring

50 points per correct trial, plus a speed bonus for each part’s average time.

Difficulty levels

Easy has 4 trials per part, Normal 5 and Hard 6.

Tips
