Summary
Researchers developed a new tool to measure interpersonal coordination during conversation. This objective evidence shows people
Area of Science:
- Psychology
- Human Behavior
- Social Interaction
Background:
- Interpersonal coordination is crucial for effective social interaction.
- Quantifying real-time coordination during conversation remains challenging.
Purpose of the Study:
- To introduce and validate a novel measurement tool for interpersonal coordination.
- To objectively assess postural sway coordination during dyadic conversation.
Main Methods:
- Employed cross recurrence quantification (CRQ) analysis on postural time series.
- Reconstructed phase space to analyze shared activity between participants.
- Compared coordination during a cooperative puzzle task versus general conversation.
Main Results:
- Participants exhibited greater shared activity (recurrence) when conversing to solve a puzzle.
- Postural trajectories showed less divergence during cooperative conversation.
- This indicates objective evidence of interpersonal coordination.
Conclusions:
- The new CRQ tool effectively measures interpersonal coordination.
- Coordinated postural sway is linked to cooperative verbal tasks.
- This provides objective insights into social interaction dynamics.
