What is the visual reaction time of a normal person?
The average visual reaction time of a normal person is about 200-250 milliseconds. This is the time it takes for a person to see a stimulus and react to it. Factors like age, fatigue, and distractions can affect reaction time.
What is the difference between normal reaction and abnormal reaction?
A normal reaction is a response that is considered typical or expected in a given situation. An abnormal reaction, on the other hand, is a response that deviates from what is considered typical or expected, and may indicate a problem or issue that needs to be addressed.
Who discovered reaction time?
Sir Francis Galton is credited with pioneering the study of reaction time in the late 1800s. Galton's research laid the foundation for understanding human response to stimuli and its variations.
How long does it take a human to react?
On average, a human reaction time is about 0.25 seconds to 0.3 seconds for simple stimuli. This can vary based on factors such as age, fatigue, and distraction.
