Exploration reveals how interoceptive accuracy influences timing in participants, highlighting connections to cardiac activity.

Better interoceptive accuracy is linked to faster response speed in implicit timing tasks, suggesting enhanced motor readiness.
In explicit timing tasks, greater subjective confidence in heartbeat detection correlates with poorer performance, indicating potential over-reliance on interoceptive signals.
Higher vagal tone, suggested by elevated heart rate variability, is associated with a quicker rhythm in explicit timing tasks.
These findings underscore the distinct roles of cardiac interoception and activity in explicit versus implicit timing perception.

Cristaldi et al. (2025) studied this question.
