Full Abstract
Effective collaboration requires teams to manage complex cognitive and emotional states through Socially Shared Regulation of Learning (SSRL). Physiological synchrony (i.e., longitudinal alignment in physiological signals) can indicate these states, but is hard to interpret on its own. We investigate the physiological and conversational dynamics of four medical dyads diagnosing a virtual patient case using an intelligent tutoring system. Semantic shifts in dialogue were correlated with transient physiological synchrony peaks. We also coded utterance segments for SSRL and derived cosine similarity using sentence embeddings. The results showed that activating prior knowledge featured significantly lower semantic similarity than simpler task execution. High physiological synchrony was associated with lower semantic similarity, suggesting these moments involved exploratory and diverse language use. Qualitative analysis triangulated these synchrony peaks as 'key moments': successful teams synchronized during shared discovery, while unsuccessful teams peaked during shared uncertainty.
Key Takeaways
- Setting: Four medical dyads diagnosed a virtual patient case using an intelligent tutoring system.
- Method: Dialogue segments were coded for SSRL; cosine similarity was computed from sentence embeddings and correlated with physiological synchrony peaks.
- Finding 1: Activating prior knowledge showed significantly lower semantic similarity than simple task execution.
- Finding 2: High physiological synchrony coincided with lower semantic similarity, implying exploratory, varied language use.
- Finding 3: Synchrony peaks corresponded to distinct 'key moments'—shared discovery in successful teams versus shared uncertainty in unsuccessful teams.
