Choice Reaction Time Test

What to do: A coloured box will appear. Press the correct arrow key as fast as you can.

BLUE box

Press LEFT arrow (←)

YELLOW box

Press RIGHT arrow (→)

During the wait: The box will be red. Do not press anything while it is red.

If you press too early, that trial will restart automatically.

Speed and accuracy both matter. Errors are recorded separately so don't rush so much that you press the wrong key.

30 trials in total. The test takes around 3 minutes.

First time taking this test? It takes a trial or two to get the key mappings into your fingers. Feel free to take it again and use the second set of results.
