About Reaction Time

What it measures

This is a simple tool to measure your reaction time.

How it works

The average (median) reaction time is 273 milliseconds, according to data collected so far. the data

Why it matters

In addition to measuring your reaction time, this test is affected by the latency of your computer and monitor. Using a fast computer and low latency / high framerate monitor will improve your score.

About the aim trainer

Scores in this test are faster than the aim trainer test, because you can react instantly without moving the cursor. aim trainer

More details

This is discussed in further detail on the statistics page. While an average human reaction time may fall between 200-250ms, your computer could be adding 10-50ms on top. Some modern TVs add as much as 150ms! statistics

Physiology• Neurobiology & Physiology

What is reaction time?

Reaction time is the duration between the presentation of an external sensory cue (such as visual color change) and the physical initiation of a motor action. It involves four distinct physiological steps:

Step 1

Detection

Sensory Transduction

Retinal photoreceptors absorb light photons and convert them into electrical action potentials (15–30 ms).

Step 2

Transmission

Optic Pathway

Impulses travel along the optic nerve and thalamus to the primary visual cortex V1 (20–40 ms).

Step 3

Decision

Cognitive Processing

Premotor and prefrontal cortex register the trigger and initiate the motor command (80–120 ms).

Step 4

Action

Motor Execution

Efferent nerve impulses travel down the spinal cord to forearm muscles to depress the switch (30–50 ms).

Global Median• POPULATION BELL CURVE

What is the average reaction time?

The biological average human reaction time is 200–250 ms for visual stimuli in laboratory conditions. In online browser tests, the global median sits around 273 ms due to display refresh rates and input polling.

200–250 ms (Web: 273 ms)#1

Visual Stimulus (Sight)

Standard visual baseline. 60Hz displays add ~16.7 ms latency per frame; 144Hz+ monitors reduce this to < 7 ms.

200–250 ms

140–160 ms#2

Auditory Stimulus (Sound)

Sound waves mechanically stimulate cochlear hair cells, reaching the brainstem auditory cortex in only 8–10 ms.

140–160 ms

~150 ms#3

Tactile Stimulus (Touch)

Somatosensory pathways utilize direct spinal reflex arcs for rapid physical reaction.

AGE BENCHMARKS• LIFESPAN DEMOGRAPHICS

Year-Old Reaction Times: Average Reaction Time by Age

Reaction time follows a lifespan curve: nerve conduction speeds up through childhood, peaks between ages 18 and 24, and gradually slows by 2 to 6 ms per decade as dopamine receptor density gently declines.

The 13-Year-Old Advantage

///

A 13-year-old’s nervous system conducts impulses at near-peak speeds (~120 m/s). Young gamers frequently achieve sub-200 ms reaction times due to fresh synaptic plasticity.

The Age 20–24 Apex

///

While teens possess lightning twitch speed, ages 20–24 combine rapid firing with full prefrontal myelination, drastically cutting false starts and miss-clicks.

Optimization• PERFORMANCE DRILLS

How to improve Reaction Time?

You can measurably shave 20–50 ms off your reaction times by optimizing hardware latency, physical physiology, and visual focus techniques:

144Hz+ Display & 1000Hz Mouse

MEMORY BOOST

Cuts frame latency from 16.7 ms (60Hz) to 4.1 ms (240Hz), and mouse polling delay from 8 ms to 1 ms.

7–9 Hours Quality Sleep

BETTER VISUAL RESPONSE

Sleep deprivation degrades reaction times by 30–50 ms, identical to low-level alcohol impairment.

Hydration & 50–100mg Caffeine

STAY PRESENT

Mild caffeine blocks adenosine receptors, sharpening central nervous system alertness by 10–20 ms.

Soft Peripheral Focus

AVOID EYE FATIGUE

Relax your gaze; peripheral rod photoreceptors detect brightness transitions faster than central foveal cones.
