Background

Earlier work that helps you think about the practice, without being about it.

The usual measures of between-brain synchrony found coupling in simulated signals where there was none, and in pairs of people recorded separately, because doing the same task gave their EEG similar rhythms.

What it doesn’t show

A test of analysis methods, not a study of interaction. It recommends one measure as less prone to the problem; it does not show that any measure removes it.

Summary based on the abstract and the full text’s methods.

    Does brain activity fall into step across a circle in the moments participants feel met, beyond what shared speech and attention explain?
