Partial acts as enablers of shared embodied rationality

Sébastien Lerique & Tom Froese

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

Perceptual Crossing Paradigm

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
