The interacting partner as the immediate environment: Personality, interpersonal dynamics, and bodily...

Area of Science:

• Psychology
• Social Interaction Dynamics
• Nonverbal Communication

Background:

• Humans naturally synchronize body movements during social interactions.
• Interpersonal synchronization is a key aspect of social communication.
• Understanding its link to personality and interaction outcomes is crucial.

Purpose of the Study:

• To investigate interpersonal synchronization in conversations.
• To examine the relationship between bodily synchronization, personality differences (Agreeableness, Extraversion), and post-interaction appraisals.
• To explore how synchronization varies across different conversational contexts.

Main Methods:

• 112 young adults in 56 dyads engaged in semi-structured conversations (introductions, self-disclosure, arguments).
• Bodily movements were video-recorded and analyzed for synchronization strength (Windowed Lagged Cross-Correlations) and dynamic organization (Cross-Recurrence Quantification Analysis).
• Personality was assessed using the IPIP-NEO-120, and post-interaction appraisals (affect, closeness, enjoyment) were measured.

Main Results:

• Higher Agreeableness correlated with more complex bodily synchronization dynamics (higher Entropy).
• Extroverts exhibited stronger interpersonal synchronization and appraised conversations more positively than introverts.
• Synchronization strength and dynamics were influenced by conversation type (self-disclosure vs. argumentative).

Conclusions:

• Interpersonal synchronization is closely tied to Agreeableness and Extraversion.
• Synchronization dynamics vary across different social situations.
• These synchronization parameters significantly impact the perceived pleasantness, closeness, and enjoyment of conversations.
