(077) Physiological Synchrony and Sexual Satisfaction: A Replication and Extension

Abstract Introduction Physiological synchrony (PS) refers to a pattern of psychophysiological covariation in the context close relationships that is thought develop as function dynamic, reciprocal exchanges across biological systems over time (for review, see Palumbo et al., 2017). There strong evidence suggest PS marker well-being romantic relationships, with research illuminating associations between and domains relational functioning including overall relationship satisfaction feelings closeness, connection, empathy for one’s partner (e.g., Helm 2014; 2017; Timmons 2015; Countinho, 2019). More recent has extended these findings sexual finding predicts attraction potential (Prozachkova 2022) and, laboratory setting, global evaluations (Freihart & Meston, Objective Taken together, there theoretical empirical attunement partners may be relevant their relationship. Building upon data, current project seeks examine more ecologically valid context: at-home, during activity. The primary aims include: (1) replicating previous suggesting observed non-sexual interactions satisfaction, (2) whether physiological manifests activity, finally, (3) examining magnitude stronger activity than interactions. Methods Heterosexual couples monogamous, were recruited from community surrounding (University name redacted review). Participants’ autonomic response measured an ambulatory fashion baseline task, three interpersonal tasks (i.e. looking into each other’s eyes, actively attempting mirror one another, holding hands), phases (i.e., foreplay, penetrative sex prescribed position, any position selected by couple) using chest straps impedance cardiography technology. Levels via self-report measures assessed specific encounter. Results Data analyses are ongoing anticipated completion date January 2023. will updated addendum data analysis. Conclusions This first dyadic study linkages sex. illuminate candidate mechanism variation couple-level end, provide rationale future treatment development utilizing optimize outcomes.
