Very excited to share this preprint from me, @emmatempleton.bsky.social, @lindseytepfer.bsky.social & @thaliawheatley.bsky.social! "Friends and strangers engage in distinct regimes of body motion synchrony during conversation" osf.io/preprints/ps...

Forms of body motion synchrony. A) Motion quantity synchrony – synchrony in the amount of motion (orange) people engage in over time. This form of synchrony is agnostic to the direction of this movement, may be positive or negative, occurs at varying time lags, and is not specific to matched body parts across members of the dyad. B) Pseudo-synchrony – motion quantity synchrony between people who are not actually interacting. That is, members of different conversations engaging in similar amounts of motion at similar points in the conversation relative to its initiation. And C) directional synchrony – people moving the same body parts in the same direction (or along the same axis in the opposite direction) at the same time (or at some specific time lag).

Mechanisms of synchrony. A) Turn-taking, which causes increases in motion around the time of speaker role exchanges, as participants gesture to hand over or take over the floor. B) Conservation of motion in which one participant moves less when the other moves more, holding the total motion quantity relatively constant over time (note that the total amount of motion across the dyad is similar in the two panels, because one person reduces their motion to balance out the increase in the other’s motion). C) Entrainment, in which mutual following of the same conversational script leads to synchronized movement among people who are not directly interacting (i.e. pseudo-synchrony). Greeting gestures such as the handshakes depicted are one acute manifestation of this entrainment. D) Station-keeping, which maintains proxemic distance and eye level between members of the dyad. This mechanism accounts for directional synchrony, particularly between strangers who feel uncomfortable within each other’s personal space.

Motion quantity synchrony among friends and strangers. A) Friends displayed significant positive synchrony in total motion quantity at short time lags (< 2.5 s) and B) this effect generalized across the majority of body part pairs (each line represents one pair). For example, one series of points might represent the synchrony between the amount of motion in one participant’s left hand and the other’s right foot. C) Strangers displayed significant positive synchrony in total motion quantity at short time lags (< 1 s) and significant negative total motion quantity synchrony at longer time lags (2.5 – 16.6 s). D) Again, this effect generalized to most body part pairs.

Directional synchrony among friends and strangers. A) Among friends, we observed statistically significant directional synchrony in only two body parts (nose and eye) and only in the vertical axis. B) Among strangers, we observed statistically significant directional synchrony in a large number of body parts in the horizontal, vertical, and depth axes.

When you meet someone new, what kind of questions do you ask? It’s tempting to think that *really* getting to know people is just a matter of asking the right questions. Excited to share the next chapter in ongoing work on what makes a *deep question* with amazing collaborators...

📄🚨 Just published! We used EEG hyperscanning during naturalistic conversations to investigate interpersonal alignment at three distinct levels: brain-to-brain (neural coordination), brain-to-speech (neural speech tracking), and speech-to-speech (prosodic adaptation). (1/2) doi.org/10.1016/j.ne...

Recruiting PhD students for Fall 2027! This fall, I will be starting as an Assistant Professor at Texas A&M, where I will launch the Coupled Minds Lab. We will study how conversation shapes the way people connect, coordinate, and change their minds. Learn more: coupled-minds.github.io

New peer-reviewed paper w/ @mheilbron.bsky.social, @predictivebrain.bsky.social & Jakub Szewczyk! Pre-onset brain encoding has been taken as evidence that brains–like LLMs–predict upcoming words. We show that the same signatures arise in systems that cannot predict. (elifesciences.org) (1/8)

What makes us want to stay engaged in a conversation? How do we modulate our voices to be engaging? Excited to share our new paper, "Not Worth My Time! Understanding Factors That Make Speech Socially Engaging". doi.org/10.1037/xhp0...

How do people reach agreement on public health issues? Using fMRI hyperscanning + NLP, we found that when conversation partners aimed to compromise rather than persuade, they explored a wider range of mental states and topics — and ended up agreeing more. psycnet.apa.org/record/2027-...

📣 New paper out in the Proceedings of the Royal Society B in which we investigated whether conversational alignment — the tendency to reuse each other's words, syntactic constructions, topics, sounds and gestures — can be used as a reliable individual trait. It cannot! 🧵 1/4 doi.org/10.1098/rspb...

Just wrapped up an inspiring few days at #CNS2026. It was very rewarding to present my work here (my first Data Blitz presentation!) and to connect with other people also working on speech processing and social interaction. Lots of ideas to take home!

Presenting at #CNS2026 in Vancouver! "Conversational engagement modulates neural speech tracking in real-time dialogue" (Poster D106) When? - Data Blitz Session 3 (Saturday, March 7, 10:30 am); - Poster Session D (Monday, March 9, 8:00 am). I’d love to connect and exchange ideas :)

New study out in Neuron: doi.org/10.1016/j.ne.... This work led by Zaid Zada uses fMRI hyperscanning of real dyads to show that speaking and listening rely on shared neural systems; and that conversation recruits unique brain processes that aren't observed in passive comprehension.
