Partial acts as enablers of shared embodied rationality
Sébastien Lerique & Tom Froese
CILC5 2021
On the need for system-level study
Partial acts
Emerging agreement on what it is to share presence with another person
Control ↔ vulnerability
a.k.a. Complex Systems
Rationality → utility → game theory

There are no unobtrusive motion-tracking tools to assess real-time social interaction dynamics (Schilbach 2019)
Real-life social functioning is driven by basic social interactive capacities
Participants co-regulate their interaction with few constraints
The experimenter can control the way participants can couple to each other
