Physiological Coregulation during Social Support Discussions
Close relationships are proposed to function as dynamic regulatory systems, whereby partners regulate each other’s emotions and physiology to maintain an equilibrium level of responding—–a process known as coregulation. Coregulation is proposed to contribute to well-being, yet little is known regarding when coregulation emerges. We hypothesized that because social support interactions involve explicit interpersonal emotion regulation attempts, they might be especially likely to engender beneficial patterns of coregulation. We conducted a dyadic laboratory experiment in which romantic couples completed social support and control discussions as cardiovascular responses were measured. To assess physiological self-regulation and dyadic coregulation, we used dynamical systems modeling with Bayesian estimation, which captures the frequency of oscillations around an equilibrium level and changes in amplitudes over time. Results indicated the presence of coregulation across discusisons as a whole, as well as dierences in coregulation by discussion type and gender. Self-regulatory and coregulatory dynamics were more pronounced during social support (vs. control) discussions, especially when the male partner received support. There was also substantial between-dyad heterogeneity in self- and coregulation, suggesting that some dyads showed pronounced regulatory dynamics whereas other did not. Overall, this work suggests the role of social support as a coregulatory context and oers novel insights into emotional dynamics linking relationships and health.
