What it measures
Measures motor speed. Participants tap one key as fast as they can with one index finger for 10 seconds at a time, the F key with the left hand and the J key with the right. The main score is the mean number of taps per trial with the hand they write with.
Constructs
- Motor speed
- Fine motor control
- Hand dominance
Research uses
- Motor speed and aging research
- Neurological and movement research
- Within-study group comparison
How the paradigm works
The finger tapping task measures motor speed. Participants tap one key as fast as they can with one index finger: the F key with the left hand and the J key with the right. Each trial lasts 10 seconds from the first tap, and only taps within those 10 seconds count. The standard run has 5 trials with each hand, taking turns and starting with the hand the participant writes with, with a 10-second rest between trials. A study can set 3 to 10 trials per hand, run each hand's trials in a block, and set the writing hand instead of asking.
More about the paradigm
A 5-second practice trial with each hand comes first, followed by the number of taps counted, so a wrong key shows up before the test. Nothing on the screen changes while the participant taps, and no count is shown during the test. Each trial saves the time of every tap and key release from the first tap, presses of other keys, and the repeats produced by holding the key down. A trial with no tap in 30 seconds ends and counts as missed.
The main score is the mean number of taps per trial with the writing hand. The other hand's mean, the difference between the hands as a percentage of the writing hand, the time between taps and its variability, the change in rate from the first to the second half of each trial, and how long each key is held are also given. The procedure follows the finger tapping test as quantified by Shimoyama, Ninchoji and Uemura (1990) and computerized by Hubel et al. (2013), who found faster tapping with the dominant hand, in men and in younger adults, and slower, more variable tapping at older ages.
Scores
- Writing Hand Tapscount

- Mean time between consecutive taps, both hands.
- Lower is faster
- Tapping Variabilityscore
- Mean coefficient of variation of the time between taps within a trial.

- Slowing Within Trials%
- Taps in the first half of each trial minus taps in the second half, as a percentage of the first half, averaged over trials.
- Positive values mean tapping slowed within the 10 seconds
- Key Hold Timems

- Lower means shorter presses
- Writes with Left Hand0/1
- 1 when the participant writes with the left hand, which then counts as the writing hand.
- Shows which hand the scores call the writing hand
- Trials Completedtrials
- Trials with at least one tap.
- Twice the trials per hand when no trial was missed
- Missed Trialscount
- Trials with no tap within 30 seconds, left out of every mean.

How the grades work
Use: A is 1,000 or more papers from 2021 to 2025, B 300 to 999, C 100 to 299, D 30 to 99 and E fewer than 30. Evidence: A means at least 25 papers report its test-retest reliability and at least 25 registered clinical studies use it as an outcome; B, at least 8 test-retest papers, and either 5 registered clinical studies or 150 reliability or validity papers; C, at least 2 test-retest papers, 30 reliability or validity papers or 3 registered clinical studies; D, little published measurement evidence found. The counts measure use. They include every paper that names the task in its title or abstract. Grades describe the published research on this task, not ConductCognition's version of it.

Task design
The trial sequence as the test runs in ConductCognition.
- Keys
- F with the left index finger and J with the right, matched by key position on any layout.
- Trial
- 10 seconds from the first tap; only taps within them count. No count is shown while tapping.
- Trials
- 5 per hand (standard, 3 to 10), taking turns from the writing hand or in blocks, with a 10 second rest between trials.
- Writing hand
- Asked before the practice, or set by the study.
- Data
- The time of every tap and key release, presses of other keys and repeats from a held key.
- Practice
- A 5 second trial with each hand, then the number of taps counted.
The scores support research on motor speed and do not diagnose a movement disorder.
Quality checks
Each session is marked valid, needs review or invalid, with the reason, before you see its scores.
Scored rows: finger_tapping_test from the scored run, one per tapping trial. Tapping has no correct answer, so accuracy is not judged against chance. A trial with no tap in 30 seconds is a missed response: more than max(3, 25%) such trials invalidate and any is flagged. A hand averaging fewer than 10 taps per trial, or 10 or more key repeats from holding the key down, is flagged for review.
Why these rules
There is no correct option to compare with chance, so accuracy is not judged against chance. Missed trials keep the platform's timed-test rule: more than max(3, 25%) invalidate and any is flagged. Fewer than 10 taps in 10 seconds with a hand, or a key held down instead of tapped, suggests the task was not done as instructed, so the session is flagged for review. A hidden tab keeps key presses from reaching the task, so a percentile is withheld after one.
