Interpersonal coordination processes facilitate interpersonal synchrony through a continuous mutual adaption and corepresentation of self and others' actions. Such a process has been found to enhance prosocial behaviors, affiliation, and trust. While research has investigated the general underlying cognitive and social mechanisms that facilitate interpersonal synchrony, much less is known about how interpersonal impairments influence it in various psychopathological conditions-such as borderline personality disorder (BPD). In this study, we investigated the role of the social cognitive processes of individuals with high BPD traits during a synchronized interaction task. Participants ( = 206) were recruited from the general population. BPD traits were assessed, and interpersonal synchrony was measured with a finger-tapping task. Participants were instructed to interact with a virtual partner (VP) that varied its adaptivity level in response to their taps across different conditions of adaptivity (α), ranging from nonadaptive to overly adaptive. After each interaction, the perception of synchrony and affect were assessed. Results showed an overall main significant effect of the adaptivity of the VP on interpersonal synchrony and the interaction experience, such that when VP adaptivity increased, asynchrony and perceived synchrony decreased. High levels of BPD traits were associated with higher asynchrony and variability, depending on the level of VP adaptivity, and an overall more negative perception of synchrony and affect. These findings show that high BPD traits are associated with reduced interpersonal synchrony during interaction. Consistent with these findings, interventions might consider the potential role of interpersonal synchrony in building the therapeutic relationship.

The predictive power of movement and electrodermal activity (EDA) synchrony has been demonstrated in various studies. Although most studies have examined each synchrony modality separately, a growing interest in the simultaneous investigation of multiple modalities has emerged. Previous research has demonstrated the importance of disentangling within and between-dyad effects, however within and between-therapist effects have yet to be investigated.

This methodological paper examines the assessment of interpersonal synchrony during a joint dancing task between mothers and their children (aged 4 to 5 years) using OpenPose. This pose estimation tool captures movement in naturalistic settings. The study analyzes 45 mother-child dyads, comparing two analytical methods for assessing synchrony, and examines their correlation with the Coding Interactive Behavior (CIB) measure of interaction quality.

This systematic review and meta-analysis examined the interplay among neural, physiological, and behavioral interpersonal synchrony. We included studies written in English, comprising human dyads, and reporting data that could be translated to correlation estimates between at least two modalities of synchrony, sourced from PsycINFO, PubMed, and Google Scholar. The initial meta-analysis, examining associations between neural and behavioral synchrony, assessed 37 samples with 1342 participants, revealed a significant medium effect size (r = 0.

Interpersonal connectedness is a central feature of human interaction that can be compromised during illness. Nonverbal signals play a crucial role in this context, and humans, like other animals, have evolved a behavioral immune system that enables individuals to detect subtle cues of sickness in others. Conversely, sick individuals often tend to avoid social interaction, a key component of sickness behavior.
