Interpersonal motor synchrony in autism: a systematic review and meta-analysis

Frontiers in Psychiatry, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 19, 2024

Introduction Interpersonal motor synchrony (IMS) is the spontaneous, voluntary, or instructed coordination of movements between interacting partners. Throughout life cycle, it shapes social exchanges and interplays with intra- inter-individual characteristics that may diverge in Autism Spectrum Disorder (ASD). Here we perform a systematic review meta-analysis to summarize extant literature quantify evidence about reduced IMS dyads including at least one participant diagnosis ASD. Methods Empirical from sixteen experimental studies was systematically reviewed, encompassing spontaneous paradigms as well paucity measures used assess IMS. Of these, thirteen (n = 512 dyads) contributed an situ neurotypical partner (TD) for ASD control groups, which could be meta-analyses. Results Reduced synchronization ASD-TD emerged both meta-analyses, although small large effect sizes (i.e., Hedge’s g) favor group are consistent data (Hedge’s g .85, p < 0.001, 95% CI[.35, 1.35], PI[-.89, 2.60]). Discussion Uncertainty discussed relative type task, measures, age range considered each study. We further discuss sharing similar experiences world might help synchronize another. Future should not only whether consistently observed how this exchanges, but also explore ASD-ASD during interpersonal exchanges.

Social motor synchrony and interactive rapport in autistic, non-autistic, and mixed-neurotype dyads

Autism, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 24, 2025

In non-autistic populations, social motor synchrony during interactions is linked to increased interpersonal rapport – a friendly connection marked by mutual understanding and ease of communication. Previous research indicates autistic individuals show lower in with both partners. However, it unclear if this affects rapport, as synchrony’s role communication may differ for individuals. The study had three aims: replicate extend previous findings reduced dyads at least one person; second, examine the relationship between ( n = 12), 17), mixed 14); third, investigate reliance on achieving among participants.

Relational Neuroscience: insights from hyperscanning research

Humans are highly social, typically without this ability requiring noticeable efforts. Yet, such social fluency poses challenges both for the human brain to compute and scientists study.

GrooVR: an open access virtual reality drumming application to improve pro-sociality using synchronous movement

Frontiers in Psychology, Journal Year: 2025, Volume and Issue: 16

Published: April 28, 2025

Interpersonal synchrony can enhance social bonding, cooperation, and reduce negative biases, especially toward out-group members. However, studying faces practical challenges. To address this, we introduce a customizable virtual reality (VR) application report two experiments evaluating its effectiveness. In the first experiment, participants drummed either in sync or out of with partner matching their gender, age, ethnicity. Synchronous drumming increased feelings affiliation but did not influence pro-social behavior an economic game. The second experiment involved Caucasian Middle Eastern avatars. only trust also reduced prejudicial attitudes refugees. These findings suggest that strengthen bonds decrease bias, offering both theoretical insights applications.

Do perceptual timing mechanisms underlie attenuated behavioral IPS in autism?

Published: Aug. 8, 2024

Interpersonal synchrony (IPS), or the temporal coordination of behavior interaction partners during social exchange, mediates natural interactions and rapport. Attenuated IPS has been shown between autistic individuals their partners; however, mechanisms this attenuation remain unclear. One possibility could lie in perceiving timing others’ behaviors. The present study aimed to relate behavioral production with perception dynamics event non-autistic adults. Autistic participants engaged naturalistic conversations a stranger, who was naïve participant’s diagnostic status. Behavioral computed using automatic video-based analysis. Participants reported experiences perceived partner, as measure interaction. A perceptual simultaneity task measured nonsocial context. Bayesian linear mixed models were used evaluate effects ratings thresholds on IPS. Expectedly, reduced for dyads including an adult. Neither ratings, nor thresholds, associated without These findings hint that attenuated may not result from atypical behaviors perception. We speculate other cognitive underlie is often observed individuals.

Neural Mechanisms of Social Interaction Perception: Observing Interpersonal Synchrony Modulates Action Observation Network Activation and Is Spared in Autism

Human Brain Mapping, Journal Year: 2024, Volume and Issue: 45(15)

Published: Oct. 15, 2024

How the temporal dynamics of social interactions are perceived arguably plays an important role in how one engages and difficulties establishing smooth may occur. One aspect is mutual coordination individuals' behaviors during interaction, otherwise known as behavioral interpersonal synchrony (IPS). Behavioral IPS has been studied increasingly various contexts, such a feature interaction inherent to autism. To fully understand interactions, or reductions thereof autism, neural basis perception needs be established. Thus, current study's aim was twofold: establish basic neuro-perceptual processing for typical observers test whether it might differ autistic individuals. In task-based fMRI paradigm, participants viewed short, silent video vignettes humans featuring variation IPS. The results show that observing modulates Action Observation Network (AON). Interestingly, showed similar activation patterns non-autistic which were modulated by they observed videos, suggesting spared not underly reduced often Nevertheless, general difference found observers, characterized decreased right middle frontal gyrus, angular superior areas. These findings demonstrate although groups indeed differed perception, these reason differences Hence, recruitment AON autism does account widely reported attenuation presently

The relationship between interpersonal distance preference and estimation accuracy in autism

PLoS ONE, Journal Year: 2024, Volume and Issue: 19(9), P. e0306536 - e0306536

Published: Sept. 9, 2024

People naturally seek an interpersonal distance that feels comfortable, striking a balance between not being too close or far from others until reaching state of equilibrium. Previous studies on preferences among autistic individuals have yielded inconsistent results. Some show preference for greater distance, while indicate shorter distances, reveal higher variance in individuals. In related vein, previous also investigated the way autistics accurately judge and these received results, with some showing superior spatial abilities indicating biases estimations. However, link estimation has never been examined. To address this gap, our study measured estimations tested correlation two factors. The results people both ability to estimate accurately, suggesting inconsistencies originate individual differences autistics. Furthermore, only were bias associated manner violated Underestimation (judging as closer than they are) was linked proximity, overestimation further away) maintaining distance. This connection suggests contribute extreme (being away). Taken together, findings suggest are socially inappropriate
