Finger tapping test online: how fast can one finger go?
Find out how fast and how steadily your index finger can tap, and whether your pace holds to the end: the fine motor speed behind typing, texting and every quick press of a button.
10 seconds of scored tapping. Tutorial and a practice round included. Nothing to prepare.
Press the button as fast as you can until the bar stops
It looks simple. Your finger may disagree.
- 1Learn and practice
A short tutorial and one practice round that count towards nothing.
- 2Tap until the bar stops
One continuous scored stretch, ended by the clock.
- 3Your results
Your speed and steadiness, read against reference ranges.
What the finger tapping test measures
The finger tapping test measures fine motor speed: how many times you can press one target with your index finger in a fixed time, with your hand resting still so only the finger moves. CogniFit's version is a digital implementation of the classic Finger Tapping Test and follows its published procedure.
It runs on a computer, a tablet or a phone, with a mouse click or a finger. There is a single control and nothing to choose between, so what it measures is speed, not decision.
Only your finger moves. Tap until the bar stops.
Rest your writing hand on the table and press the button with your index finger as fast as you can. The clock ends the round, not a number of taps.
- Hand flat on the table. Your writing hand rests still.
- Index finger only. The finger moves, not the hand.
- No feedback. You are not told how you are doing while you tap.
From first tap to results
- 1Tutorial, as often as you like
Repeat it before starting; it does not affect any result.
- 2One practice round
Unscored, to find your position and your rhythm.
- 3The scored stretch
Tap without pause until the bar runs out.
Now you know the one rule. See how long your rhythm lasts.
What a few seconds of tapping reveals
The task measures fine motor speed. It also contributes to the measurement of motor fatigue and of differences between your two hands.
- Fine motor speed
- How quickly you can repeat one small, precise movement.Everyday moment: typing a quick reply on your phone.
- Motor fatigue
- Whether that pace holds or drops as the seconds pass.Everyday moment: keeping up a steady rhythm through a long stretch of typing.
- Manual asymmetry
- How the speed of one hand compares with the other.Everyday moment: a quick task with the hand you do not write with.
Curious where your own speed sits? It takes one round to find out.
How to read your finger tapping test results
Three things tell most of the story: how fast you tapped, how steady your rhythm was, and how your first five seconds compare with your last five.
Speed
How many correct taps you made and your typical time per tap. More taps and a shorter typical time mean a faster finger. The typical time is a median: half your taps were quicker, half slower, so one slow tap does not move it.
Steadiness
How much your time varied from one tap to the next. A lower value means an even rhythm; a higher one means bursts of fast and slow. It is also weighed against your overall speed, so fast and slow tappers can be compared on steadiness alone.
First 5 seconds versus final 5 seconds
This is the task's key measure, and it is a simple comparison: count your correct taps in the first half, count them in the second. Close counts mean your pace held; fewer at the end mean your finger slowed as the seconds went by.
When the bar stops, the task shows your own results on a results screen, read against reference ranges. They place your numbers in context; they are a measure, not a medical assessment, and ranges describe groups of people rather than any one person.
The results screen also counts errors: fewer is better. If you want to see whether your numbers change over time, signing up keeps them for you.
Reading about a result is one thing. Seeing yours is another.
The science behind the finger tapping test
One of the simplest ideas in cognitive testing: hold everything still except one finger, and time how fast it can go.
The Finger Tapping Test is an experimental paradigm with a published record in the cognitive literature. Its classic description is part of the Halstead-Reitan Neuropsychological Test Battery, as set out by Reitan and Wolfson (1993),1 and Schatz (2011) summarises the test in its entry in Springer's Encyclopedia of Clinical Neuropsychology.2 Researchers keep using and examining it: Ashendorf, Horwitz and Gavett (2015) studied how far the test can be shortened,3 and Arias and colleagues (2012) looked at its validity in young and older healthy adults and in people with Parkinson's disease, and at the role central fatigue may play in the result.4
CogniFit's version follows that published procedure: what is shown, how long for, what counts as an answer and what is measured are set from it rather than invented for this implementation.
What it can tell you
How fast and how steadily your finger tapped in this session, and whether your pace held from the first half to the second.
What it cannot tell you yet
What a given score means for you as a person. That needs population data for this version that has not been collected yet. The literature supports the paradigm, not this particular implementation.
More detail: how the measures are computed
Speed and steadiness are calculated from correctly answered taps. Error taps are left out of the variation measures, because their timing comes from a different process. Alongside the median time, the task also records the mean, which one unusually slow tap can pull up.
Every session also runs quality checks, such as how many answers came back too fast to be real and how many trials were usable. They decide whether a session can be read at all, and they describe the session, not you.
The paradigm is decades of research. Your round takes a moment.
