Cautions: No later follow-up
Two minutes of a partner meditation, gazing at each other while contemplating shared humanity, raised closeness by about one standard deviation, and partners’ smiles and heart rates fell into sync.
Bodies in synchrony
Do participants’ physiology and movement synchronise during a circle, and does synchrony track felt connection?
Second-person neuroscience can measure interaction as it happens. Circling, built around attention to the live moment, is an unusually clean setting for it.
Builds on four works
Why it matters
Most evidence about closeness comes from questionnaires filled in afterwards. Physiological and behavioural synchrony can be recorded during the encounter itself, and Circling’s focus on what is happening now makes the moments of interest easier to locate.
What exists
In Ludwig et al. (2025), partners’ smiles synchronised during a two-minute partner meditation, and in person so did their heart rates. Smiling synchrony predicted how positively partners saw each other.
A possible design
Record heart rate and movement during circles (and, in a lab, EEG or fNIRS). Afterwards, ask participants to mark moments of felt connection or rupture on a timeline, and test whether synchrony rises around them.
Pitfalls
Synchrony also rises with shared stress or simple turn-taking. Compare against ordinary conversation, and treat synchrony as one signal among several, not a measure of intimacy.
