Nonverbal interpersonal synchronization has been established as an important factor in therapeutic relationships, and the differentiation of who leads the interaction appears to provide further important information. We investigated nonverbal synchrony – quantified as the coordination of body movement between patient and therapist. This was observed in music therapy dyads, while engaged in verbal interaction before and after a music intervention in the session. We further examined associations with patients’ self-reported therapy readiness at the beginning of the session. Eleven neurological (...) in-patients participated in this study. Our results showed an increase in both nonverbal synchrony and patient leading after the music intervention. A significant negative correlation was found between self-reported therapy readiness and nonverbal synchrony after the music intervention. These findings point to the empathic ability of the music therapist to sense patients’ therapy readiness. Higher patient leading in nonverbal synchrony after the music intervention may thus indicate that the music intervention may have allowed dyadic entrainment to take place, potentially increasing self-regulation and thus empowering patients.

IntroductionHearing loss has a great impact on the people affected, their close partner and the interaction between both, as oral communication is restricted. Nonverbal communication, which expresses emotions and includes implicit information on interpersonal relationship, has rarely been studied in people with hearing impairment. In psychological settings, non-verbal synchrony of body movements in dyads is a reliable method to study interpersonal relationship.Material and methodsA 10-min social interaction was videorecorded in 39 PHI and their significant others. Nonverbal synchrony, which means the (...) nonverbal behaviors of two interacting persons and verbal interaction were analyzed by computer algorithms and observer ratings. Hearing-related quality of life, coping mechanisms, general psychopathology, quality of relationship, and burden of hearing loss experienced by SOs were assessed using questionnaires.ResultsIn the 39 dyads, true nonverbal synchrony differed from pseudosynchrony [t = 2.41; p = 0.02] with a medium effect size. Gender of PHI had a significant effect on general synchrony and on leading by SOs. Age gap correlated with synchronic movements. Very short duration of hearing impairment was associated with lower nonverbal synchrony in the role of leading by SOs. Feeling of closeness by PHI correlated negatively with the role of leading by SOs and feeling of closeness by SOs was positively associated with leading by PHI. No correlation was detected between nonverbal synchrony and other questionnaires. Burden experienced by the SOs was higher in SOs who reported less closeness.DiscussionA longer hearing impairment leads to more nonverbal leading by SOs compared to PHI with very short duration of hearing loss, possibly because of the long-lasting imbalance in communication. If PHI felt more closeness, SOs led less and vice versa. Burden experienced by SOs negatively correlated with closeness reported by SOs. Use of nonverbal signals and communication might help to improve benefits of auditory rehabilitation for PHI and decrease burden experienced by SOs. (shrink)

Human interaction has two principle functions: building and maintaining relationships with others and exchanging information. The function of building and maintaining relationships with others relates to interpersonal coordination; this behavior pattern is expected to predict the outcome of social relationships, such as between therapists and patients. It is unclear, however, whether the exchange of information is associated with interpersonal coordination. In the present study, we tested a hypothesis of whether body movement synchrony occurs in a natural conversation and whether this (...) synchrony has a positive correlation with the degree of information exchange. Fifty participants were engaged in a conversation task; each had different roles in the conversation. We measured their body movements during this conversation using an optical motion capture system. Similar to methods that can be found in previous research, we calculated body movements and quantified their synchrony applying the methods previously reported that automatically quantified their body movements. Moreover, we determined the participants’ degree of information exchange concerning the conversation using a questionnaire. We observed that the body movement synchrony of pairs who talked with each other was significantly higher than that of pairs who did not talk with each other, and that this synchrony was positively associated with the degree of information exchange. These results suggest that body movement synchrony predicted information exchange. (shrink)

BackgroundResearch on interpersonal synchrony has mostly focused on a single modality, and hence little is known about the connections between different types of social attunement. In this study, the relationship between sympathetic nervous system synchrony, movement synchrony, and the amount of speech were studied in couple therapy.MethodsData comprised 12 couple therapy cases. Synchrony in electrodermal activity, head and body movement, and the amount of speech and simultaneous speech during the sessions were analyzed in 12 sessions at the start of couple (...) therapy and eight sessions at the end of therapy. Synchrony was calculated from cross-correlations using time lags and compared to segment-shuffled pseudo synchrony. The associations between the synchrony modalities and speech were analyzed using complex modeling.FindingsCouple therapy participants’ synchrony mostly occurred in-phase. Anti-phase synchrony was more common in movement than in sympathetic nervous system activity. Synchrony in sympathetic nervous system activity only correlated with movement synchrony between the client-therapist dyads. Movement synchrony and the amount of speech correlated negatively between spouses and co-therapists, meaning that the more time the dyad members talked during the session, the less bodily synchrony they exhibited.ConclusionThe different roles and relationships in couple therapy were associated with the extent to which synchrony modalities were linked with each other. In the relationship between clients and therapists, synchrony in arousal levels and movement “walked hand in hand”, whereas in the other relationships they were not linked. Generally, more talk time by the therapy participants was associated with anti-phase movement synchrony. If, as suggested, emotions prepare us for motor action, an important finding of this study is that sympathetic nervous system activity can also synchronize with that of others independently of motor action.

We address what it means to “engage in a relationship” and suggest Social Breathing as a model of immersing ourselves in the metaphorical social air around us, which is necessary for shared intention and joint action. We emphasize how emergent properties of social systems arise, such as the shared culture of groups, which cannot be reduced to the individuals involved. We argue that the processes involved in Social Breathing are: automatic, implicit, temporal, in the form of mutual bi-directional interwoven exchanges (...) between social partners and embodied in the coordination of the brains and behaviors of social partners. We summarize cross-disciplinary evidence suggesting that these processes involve a multi-person whole-brain-body network which is critical for the development of both we-ness and relational skills. We propose that Social Breathing depends on each individual’s ability to sustain multimodal interwovenness, thus providing a theoretical link between social neuroscience and relational/multi-person psychology. We discuss how the model could guide research on autism, relationships, and psychotherapy. (shrink)

The current paper addresses two methodological problems pertinent to the analysis of observer studies in nonverbal rapport and beyond. These problems concern: the production of standardized stimulus materials that allow for unbiased observer ratings and the objective measurement of nonverbal behaviors to identify the dyadic patterns underlying the observer impressions. We suggest motion capture and character animation as possible solutions to these problems and exemplarily apply the novel methodology to the study of gender and cultural differences in nonverbal rapport. We (...) compared a Western, individualistic culture with an egalitarian gender-role conception and a collectivistic culture with a more traditional gender role conceptions. Motion capture data were collected for five male and five female dyadic interactions in each culture. Character animations based on the motion capture data served as stimuli in the observation study. Female and male observers from both cultures rated the perceived rapport continuously while watching the 1 min sequences and guessed gender and cultural background of the dyads after each clip. Results show that masking of gender and culture in the stimuli was successful, as hit rates for both aspects remained at chance level. Further the results revealed high levels of agreement in the rapport ratings across gender and culture, pointing to universal judgment policies. A 2 × 2 × 2 × 2 ANOVA for gender and culture of stimuli and observers showed that female dyads were rated significantly higher on rapport across the board and that the contrast between female and male dyads was more pronounced in the Arab sample as compared to the German sample. nonverbal parameters extracted from the motion capture protocols were submitted to a series of algorithms to identify dyadic activity levels and coordination patterns relevant to the perception of rapport. The results are critically discussed with regard to the role of nonverbal coordination as a constituent of rapport. (shrink)

This study is part of a larger exploration of ‘talk and cure’ that combines the examination of talk-in-interaction, with nonverbal displays, and measurements of the client’s and therapist’s autonomic arousal during therapy sessions. A key assumption of the study is that psychotherapy entails processes of intersubjective meaning-making that occur across different modalities and take place in both verbal/explicit and nonverbal/implicit domains. A single session of a psychodynamic psychotherapy is analysed with a focus on the expression and management of affect, with (...) an aim to describe key interactive events that promote change in both semantic and procedural domains. The clinical dialogue is analysed discursively, with a focus on the conversational processes through which new meanings are jointly constructed and affective states shared; detailed attention is paid to nonverbal displays of affiliation and affect. Furthermore, we explore whether the interactional patterns implicated in joint meaning-making, as revealed by analysing the therapeutic conversation, have correlates in the autonomic arousal of the two protagonists, as reflected in their heart rates. Conversation analysis has still untapped potential to illuminate interactional patterns that underlie the practice of psychotherapy. In this exploratory study we suggest that discursive analyses of talk-in-interaction can be enriched through detailed focus on nonverbal displays as well as measures of physiological arousal. Drawing upon the analysis, we suggest that bringing the methodological strengths of language-based analysis into fertile dialogue with embodied quantitative data can help our explorations of what’s really going on in psychotherapy.
