Auditory rhythm complexity affects cardiac dynamics in perception and synchronization
Fig 4
Sample cardiac time series (in beats per minute) and recurrence plots (in number of samples) from one participant for each auditory condition and rhythm condition.
A) Perception task: Simple rhythm (left) and Complex rhythm (right). B) Synchronization task: Simple rhythm (left) and Complex rhythm (right). Black dots in recurrence plots indicate points of recurring heartbeat intervals.
