4 CHOICES · 5 VALID TRIALS
Wait for a colored arrow, then press or tap the matching direction.
READY?
Use the arrow keys on a keyboard, or the four large buttons below.
The timer starts when the arrow appears. Pressing early counts as a false start.
HOW IT WORKS
Start the test and keep your hands near the arrow keys or touch controls.
Wait through the random delay. Respond only after one colored arrow appears.
Choose the matching direction. Five correct responses complete the test.
ABOUT THE TEST
Choice reaction time measures how quickly you recognize a signal, decide which response belongs to it, and make that response. This online test uses four colored directions, so every trial includes both recognition and selection.
Your result is the average time from the arrow appearing to the correct key press or tap. Wrong choices and false starts lower accuracy but do not count toward the five valid trials.
SIMPLE VS CHOICE REACTION TIME
One known signal has one known response—for example, click as soon as the screen changes color.
Several possible signals require different responses. The decision step usually makes choice reactions slower.
QUESTIONS
There is no single score that is good for everyone. Choice reaction time depends on the number of options, the device, practice, attention, age, and testing conditions. Compare repeated sessions on the same device instead of treating one result as a diagnosis.
A simple test asks you to detect and respond. A choice test also asks you to identify the signal and select the correct response, adding a decision before the movement.
Yes. Tap the large direction buttons. Touchscreen and keyboard results can differ because the devices have different input delays, so compare like with like.
Accuracy is correct responses divided by all responses, including wrong choices and false starts. Only correct responses count toward the five valid trials.
