What is reaction test?

The reaction test is a popular choice for researchers who are looking to get an idea of how well their participants can react. The goal in this test is to respond as fast as possible after the appearance of a stimulus, which in most cases is a visual signal (e.g., flickering lights).

Imortance of reaction time test

The reaction time test is a simple, non-invasive method of measuring a person’s reaction time. There are many reaction tests on the internet that you can use for this purpose. However, only a few provide accurate results.

In reaction speed testing the participant presses a button as soon as he notices something happening on the screen of his monitor (e.g., the appearance of a stimulus). A reaction time will usually not be faster than 200 ms if no distraction effect occurs. The average reaction times decrease with increasing age but the speed depends also on other factors such as fatigue and concentration level.

This is why it is also called Attentional Network Test (ANT), it tests multiple networks, cognitive reaction time, motor reaction time and reaction time to a specific stimulus.

In general reaction times can be classified as follows:

  • Simple reaction time (SRT) – reaction to a stimulus that appears unexpectedly on the screen or in case of no distraction effects
  • Choice reaction time (CRT) – reaction to a stimulus after the participant has been given some information about what kind of stimulus will appear next. This is also known as “go/no go” reaction test since it addresses whether the participant pressed a button or not. In CRT experiments there are usually four possible stimuli from which only one is correct at every trial.
  • Recognition reaction time (RRT) – reaction when the stimulus was already expected by the participant. This reaction time test is also known as “go/no go reaction test” because it addresses whether the participant pressed a button or not. In RRT experiments there are usually four possible stimuli from which only one is correct at every trial.

How reaction times can be affected?

  • Fatigue and lack of sleep
  • Age
  • Alcohol consumption

Common uses of Reaction Speed Test

An online reaction time test is a simple way to monitor an individual’s reaction time. Reaction times are commonly studied in sports, car safety, education realms and many other fields. Researchers have found that reaction time tests are among the best predictors of accidents at home or on the road, attention skills in schoolchildren, job performance, cognitive impairment and susceptibility to certain diseases.

The reactions speed test works by measuring how quickly a person can react or respond typically after being given some kind of stimulus. For example, if researchers want to measure someone’s reaction speed while driving they will show them an object on their screen which could be anything from a change in color to an animal running out into the road then the driver has to move the steering wheel to avoid hitting it.

The reaction speed testing is very easy to implement, can be applied in many different settings and produces consistent results which makes it ideal for all sorts of research. Reaction tests are often used in educational settings as an indicator of cognitive ability or intelligence. The reaction timing test works by giving a subject some kind of stimulus either through sight or sound then seeing how quickly they respond usually measured through reaction times screens that have small lights or sounds that flash on screen and timing subjects reaction with a stopwatch.

A reaction timing test can work even if the person is unaware that they are being tested on their reaction skills as long as some sort of stimulus has been given to the events like this happen commonly when studying infants and reaction times tests are just as effective when used with them.

How fast can you react? – Find your accurate reaction speed

This test is a simple way to measure your reaction timing, or how fast you can react to a sensory stimulus. People with faster reaction times tend to have better hand-eye coordination and are more likely to excel at sports requiring good reflexes.

Individuals from different age groups will react differently as their ‘reaction time’ changes as they get older. The reaction time test here has also been designed to test the reaction times of people from different age groups. Reaction times are usually measured in increments of hundredths of a second, so reaction times below 0.100 seconds are rounded up to 0.100 seconds.

Reaction Time Tester – FAQ’s

What is an average reaction time speed?

Averagely, a common person reacts between 200 ms to 300 ms.

What is the good reaction time speed?

A reaction time speed below 150 ms can be considered a good reaction speed.

What is the faster reaction time speed?

Any reaction time between 51 ms to 99 ms is a very good reaction timing.

What is the Excellent reaction time speed?

A reaction time speed below 50 ms can be considered an excellent reaction speed timing. Which is very hard to achieve and needs lots of practice to get these results.

Is 150 ms reaction time good?


we can consider 150 ms reaction time as a good reaction speed because ordinary people (especially excluding gamers) achieve 200 ms to 300 ms speed after some real excersize. In order to achieve this score they need to practice & hard working. Furthermore, accordingly to online surveys the collected data shows that only 1% people can achieve reaction flex speed 150 or Lower. This also proves that achieving  the 150ms or below to this figure is quite impressive speed.
