The Impact

Abstract This study examined ways in which rhythmic features of movement contribute to bonding between individuals. Though previous studies have described synchrony as a form of social glue, this research extends those findings to consider the impact of fast versus slow tempo on movement synchrony. This two-part experiment examined dyadic interactions as they occurred between same-sex strangers (Study 1) and friends (Study 2). Participants were video-recorded as they engaged in 5- or 6-min chats, and synchrony was evaluated using wavelet transform via calculations of cross-wavelet coherence. Study 1 employed regression commonality analysis and hierarchical linear modeling and found that among various frequency bands, rapport between individuals was positively associated with synchrony under 0.025 Hz (i.e., slower than once every 40 s) and 0.5–1.5 Hz (i.e., once every 0.67–2 s). On the contrary, Study 2 determined that synchrony of 0.5–1.5 Hz was not impactful among friend dyads and only predictive of the motivation to cultivate a friendly relationship during interactions with strangers. These results indicate the existence of a distinctive rhythm for bonding individuals, and the role of pre-existing friendship as a moderator of the bonding effect of synchrony. However, the role of relative phase (i.e., timing of movement; same versus opposite timing) remains unclear, as the ratio of in- and anti-phase patterning had no significant influence on perceived rapport and motivation to develop relationships. On the basis of the research results, a theoretical contribution is proposed to the study of interpersonal coordination.

Nonverbal Synchrony

AbstractResearch on nonverbal synchrony (movement coordination) in psychotherapy has recently attracted increased attention. Nonverbal synchrony has been shown to relate to the therapeutic alliance and outcome. However, research on nonverbal synchrony in couple therapy remains scarce. In this study, we examined the therapy process of one couple in detail and created a coding scheme to depict posture and movement synchrony. In this case study, we found that the relationship between nonverbal synchrony and the therapeutic alliance was complex. During the therapy process, the amount of nonverbal synchrony varied, as did the participants’ evaluations of the alliance. In couple therapy nonverbal synchrony could affect both the persons involved in it and the persons observing it. In one of the sessions, almost all the synchronies occurred between the female client and one of the therapists, and all except the female client evaluated the alliance to be weaker. In this case study, there were two therapists present, and the co-therapists’ synchrony was found to be important for the male client’s evaluations of the alliance. When there was more synchrony between the therapists, he evaluated the alliance to be stronger. Interestingly, the co-therapists’ synchrony seemed to peak in sessions that succeeded sessions with a weaker alliance, as if the therapists were implicitly making a joint effort to strengthen the alliance. A short episode from one session is given to illustrate the findings. Our coding scheme enables studying nonverbal synchrony (posture and movement synchrony) in couple therapy and combining the research results to other temporally precise data obtained from the sessions. More research is needed to validate the method.

AbstractThe extent to which hand dominance may influence how each agent contributes to inter-personal coordination remains unknown. In the present study, right-handed human participants performed object balancing tasks either in dyadic conditions with each agent using one hand (left or right), or in bimanual conditions where each agent performed the task individually with both hands. We found that object load was shared between two hands more asymmetrically in dyadic than single-agent conditions. However, hand dominance did not influence how two hands shared the object load. In contrast, hand dominance was a major factor in modulating hand vertical movement speed. Furthermore, the magnitude of internal force produced by two hands against each other correlated with the synchrony between the two hands’ movement in dyads. This finding supports the important role of internal force in haptic communication. Importantly, both internal force and movement synchrony were affected by hand dominance of the paired participants. Overall, these results demonstrate, for the first time, that pairing of one dominant and one non-dominant hand may promote asymmetrical roles within a dyad during joint physical interactions. This appears to enable the agent using the dominant hand to actively maintain effective haptic communication and task performance.
