duet: An R package for dyadic analysis of motion data generated by OpenPose - Behavior Research Methods Research into dyadic social interactions has expanded significantly, enabling a deeper understanding of the dynamic processes underlying interpersonal communication. As the use of larger datasets becomes increasingly common in this field, the need for scalable and efficient analytical tools has grown. Automated coding methods, such as those provided by OpenPose, an open-source software for detecting and tracking human motion, offer significant advantages for analysing the movement of two individuals during an interaction. However, the processing and analysis of large quantities of JSON output files generated by OpenPose remain a considerable challenge. To address this, we introduce duet, an R package designed to streamline the processing and analysis of OpenPose output data, particularly in the context of dyadic interactions. The package provides a suite of functions for data cleaning, interpolation, kinematic analysis, and visualisation, offering researchers a comprehensive and user-friendly workflow. By simplifying the handling of OpenPose data, duet aims to facilitate large-scale, automated analysis of dyadic social interactions, with minimal coding experience, thereby advancing methodological capabilities in social and behavioural sciences.

📢 New paper out in Behavior Research Methods!

With @cjcrompton.bsky.social we introduce duet, an R package for analysing dyadic motion data from OpenPose.

It simplifies data wrangling, kinematics, & synchrony analysis of social interactions.

While autistic people had longer talking turns, this didn't explain the rapport gap. Our findings challenge a purely deficit-based view of autistic communication.

The context mattered most. Autistic participants reported the highest rapport when they knew their partner was also autistic, supporting the idea of a distinct autistic social style that thrives between autistic people. #DoubleEmpathyProblem

Diagnostic status influences rapport and communicative behaviours in dyadic interactions between autistic and non-autistic people A growing body of research suggests that the behaviours and experiences of autistic and non-autistic people are influenced by whether they are interacting with someone of the same or different diagnos...

Does neurotype affect social connection? Our new @PLOSONE paper finds autistic people report lower rapport in conversations, but it's not that simple. We found that awareness of who you're talking to is key!

You may have heard me mention that we’ve been doing a follow-up study of our 2020 diffusion chain study which compared how autistic groups, non-autistic groups and mixed groups share information and build rapport (published in @journalautism.bsky.social journals.sagepub.com/doi/full/10....)

So honoured our work on social motor synchrony and rapport received an INSAR award! While I regret not being there in person tomorrow, the brilliant @sarah-foster.bsky.social will be presenting. Please stop by Poster 442.292 in Hall 4A at 12:30 to chat with her! #INSAR2025

V cool finding showing autistic people are not so dependent on synchrony to feel positive about an interaction (without showing less synchrony overall compared with non-autistic pairs)

Also the first ever registered report published in @journalautism.bsky.social !!

This registered report was peer-reviewed before data collection, underscoring our commitment to rigorous, transparent research. Excited to see where this insight into social communication takes us! #AutismResearch #SocialPsychology #RegisteredReport

What It Means: Non-autistic people may rely more on movement synchrony as a key ingredient for social bonding, whereas autistic individuals might use other cues to build connections.

Key Finding #2: However, synchrony has a stronger positive impact on rapport in non-autistic pairs. Non-autistic individuals needed higher synchrony to feel connected, while autistic individuals achieved similar rapport with less synchrony.

Key Finding #1: Contrary to past assumptions, dyads with an autistic person did NOT show less synchrony overall compared to non-autistic pairs.

Our Aims:
Replicate previous findings on reduced synchrony in dyads with at least one autistic person
Examine how synchrony relates to rapport in autistic, non-autistic, and mixed pairs
Compare reliance on synchrony for building rapport between autistic and non-autistic people.

Social Motor Synchrony: It’s that subtle mirroring of body movements during conversations that boosts connection & understanding. But does it play the same role in autistic vs non-autistic interactions?

I'm excited to share my first registered report on social interactions in @journalautism.bsky.social! Our study explores how social motor synchrony – the natural mirroring of movements – impacts rapport between autistic, neurotypical, and mixed dyads. Thread 👇
