People can intentionally or automatically synchronize movements with others. Brain imaging reveals visual areas aid coordination in joint action, while the cerebellum preserves individual tempo in non-interactive tasks, showing flexible visuomotor information use.
Area of Science:
- Neuroscience
- Social Psychology
- Motor Control
Background:
- Interpersonal coordination during social activities relies on visuomotor information exchange.
- Voluntary and spontaneous synchronization processes are key but their neural basis is unclear.
Purpose of the Study:
- To investigate the brain correlates of voluntary (Joint Action) and spontaneous (Non-interactive) interpersonal synchronization.
- To understand how the brain utilizes visuomotor information for coordination versus maintaining individual motor stability.
Main Methods:
- Functional magnetic resonance imaging (fMRI) was used to scan 30 participants performing a finger-tapping task.
- Participants either synchronized with a partner (Joint Action) or resisted synchronization (Non-interactive) under varying tempo conditions.
Main Results:
- Tempo contagion (adapting to a partner's tempo) occurred in both conditions.
- Joint Action showed positive correlation between tempo contagion and lateral occipitotemporal cortex (LOTc) activity.
- Non-interactive tasks showed negative correlation between tempo contagion and cerebellar activity, suggesting preserved individual stability.
Conclusions:
- The brain flexibly uses visuomotor information differently based on synchronization goals.
- LOTc activity supports co-regulation for synchronization, while the cerebellum acts to prevent unwanted entrainment.
- Negative functional connectivity between cerebellum and LOTc supports the distinct roles in motor interactions.
