Choice Reaction Time Test

Wait for a colored box to light up, then click it as fast as possible. Early or wrong clicks count as errors. Lower average RT wins.

About This Test

About Choice Reaction Time

Choice RT measures how quickly you select the correct option among multiple alternatives after a stimulus appears—closer to multi-button real life than simple one-button RT.

Task Flow

Several boxes wait. After a random delay, one lights. Click only that box. Early clicks and wrong boxes are errors.

Why Random Delays

Random foreperiods stop pure anticipation so you measure decision-plus-motor latency, not prediction.

Difficulty

Beginner uses fewer choices; harder modes add boxes, tighten timing, and may show decoy highlights on Professional.

Score Meaning

Average RT in ms on correct hits—lower is better. Best RT stores your best average for that difficulty.

Training Tip

Hover readiness without twitching. Choice errors explode when you guess early.

Hick's Law Intuition

More alternatives generally slow choice RT. That is why 4-box averages should not be compared naively to 2-box averages. Log difficulty beside every personal best.

Information Before Motion

The winning pattern is perceive → select → move. Starting the mouse motion before the light appears creates early-click faults and messy averages.

Hardware Notes

Display refresh and input lag add milliseconds. Keep the same monitor and mouse when tracking progress over weeks.
