Finger Tapping Task

HED task ID: hedtsk_finger_tapping

Family: Motor performance and speeded response tasks

Also known as: FTT, Tapping Task, Finger Tapping

Repetitive single-finger or sequence tapping at fastest or paced rates; taps-per-interval and tap-timing variability index motor speed and rhythm control.

Description

Participants tap their fingers (typically index finger) in a repetitive manner at a self-paced or externally paced rate. Self-paced tapping is typically at 2-3 Hz; externally paced versions use an auditory or visual metronome. The task consists of tapping blocks (20-40 seconds) alternating with rest periods. Performance metrics include tapping frequency, inter-tap interval variability, and accuracy. It is the most commonly used simple motor paradigm for motor cortex mapping, clinical motor assessment, and studying motor control. Contralateral primary motor cortex and supplementary motor area are consistently activated.

Inclusion test

An experiment is an instance of this task when its procedure matches, it manipulates at least one of the listed variables, and it records at least one of the listed measures.

Procedure

Participants tap a key or button with a single finger as rapidly as possible (maximum rate) or in synchrony with a metronome (paced tapping).

Manipulation

Hand (dominant vs. non-dominant); pacing rate; tapping duration; sequence complexity (single finger vs. sequence).

Measurement

Tapping rate (taps/sec); inter-tap interval variability; synchronization error and drift in paced conditions.

Variations

Named versions that change what the participant experiences or does. The identifier of a variation is hedvar_<task>__<variation>.

Variation

Description

Justification

Self-Paced Tapping

hedvar_finger_tapping__self_paced_tapping

Internally generated rhythm; tests endogenous motor timing.

Participant taps at preferred rate; measures preferred motor tempo

Auditorily-Paced Tapping

hedvar_finger_tapping__auditorily_paced_tapping

Synchronize to metronome; sensorimotor synchronization.

Synchronize to auditory metronome; different sensorimotor integration

Visually-Paced Tapping

hedvar_finger_tapping__visually_paced_tapping

Synchronize to visual cues; cross-modal timing.

Synchronize to visual metronome; different sensory modality for pacing

Unimanual vs. Bimanual

hedvar_finger_tapping__unimanual_vs_bimanual

Single hand vs. coordinated bilateral tapping.

One vs. two hands; bimanual coordination introduces interlimb constraints

Sequential Multi-Finger

hedvar_finger_tapping__sequential_multi_finger

Thumb-to-finger sequences (1-2-3-4-5); motor sequence complexity.

Specific finger sequence rather than single finger; different motor programming

Complex Rhythmic Patterns

hedvar_finger_tapping__complex_rhythmic_patterns

Non-isochronous rhythm reproduction; higher-order timing.

Non-isochronous rhythm; changes temporal structure of tapping

Continuation Paradigm

hedvar_finger_tapping__continuation_paradigm

Synchronize, then continue without pacing; tests internal clock.

External pacing withdrawn mid-task; isolates internal vs. externally guided timing
