What is Reaction Time?
Reaction time is the interval between the presentation of a stimulus and the initiation of a response. In simpler terms, it's how quickly you can respond to something you see, hear, or feel.
Average Reaction Times
- Visual Stimulus: 200-250 milliseconds
- Audio Stimulus: 140-160 milliseconds
- Touch Stimulus: 150-180 milliseconds
Our test measures visual reaction time – how quickly you can respond to a color change on your screen.
Factors That Affect Reaction Time
Several factors can influence your reaction time:
- Age: Reaction time typically peaks in your 20s and slows with age
- Fatigue: Being tired can significantly slow your responses
- Physical Fitness: Regular exercise can improve reaction time
- Caffeine: Moderate amounts can temporarily improve alertness
- Practice: Regularly testing can help improve your scores
- Equipment: Monitor refresh rate and input lag affect measured times
