CHOICE REACTION TEST

This is completely normal and explained by Hick's Law. In a simple test, your brain only has one job: wait for the color change and click. In this test, your brain must see the image, identify if it is pointing left or right, decide which corresponding finger needs to move, and then execute the action. That extra 'decision' step takes the brain roughly 100 to 150 extra milliseconds.

For a healthy adult, the average choice reaction time is between 380 and 450 milliseconds. Scores under 350ms are considered very fast, and scores under 300ms are elite.

In moderation, yes. Caffeine acts as a central nervous system stimulant that increases alertness and can slightly reduce reaction times. However, too much caffeine can cause jitteriness, anxiety, and a loss of focus, which will actually increase your error rate and ruin your score.

You are likely prioritizing speed over accuracy, causing your motor cortex to send a signal before your visual cortex has finished confirming the direction of the arrow. Slow down intentionally for 5 rounds to achieve 100% accuracy, then gradually increase your speed.

Yes. Standard membrane keyboards have a higher 'actuation force' and longer travel distance, plus they may have lower USB polling rates. A gaming mechanical keyboard with linear switches registers the keypress faster, potentially shaving 10 to 20 milliseconds off your physical response time.

Yes, studies consistently show that individuals who play fast-paced action video games have faster choice reaction times than non-gamers. Their brains are highly conditioned to rapidly process complex visual information and execute precise motor functions.
