📢 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. Paper: doi.org/10.3758/s134...

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.

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

First up, @themisefth.bsky.social 🌟INSAR AWARD WINNING 🌟poster on social motor synchrony and rapport in autistic, non-autistic and mixed dyads. Poster 442.292, Hall 4A, Saturday 12.30!

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 !!

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 👇 journals.sagepub.com/doi/10.1177/...
