Abstract
Empathy is a multidimensional construct that includes changes in cognitive, affective, and physiological processes. However, the physiological processes that contribute to empathic responding have received far less empirical attention. Here, we investigated whether physiological synchrony emerged during an empathy-inducing activity in which individuals disclosed a time of suffering while their romantic partner listened and responded (N = 111 couples). Further, we examined the extent to which trait and state measures of cognitive and affective empathy were associated with each other and with physiological synchrony during this activity. We found evidence for physiological synchrony in skin conductance reactivity and also in interbeat interval reactivity, though only when disclosers were women, but not for respiratory sinus arrhythmia reactivity. Physiological synchrony was not consistently associated with other well-established trait and state measures of empathy. These findings identify the nuanced role of physiological synchrony in empathic responding to others’ suffering.

Notes
Participants also took part in other tasks (reading to each other, discussing something they wanted their partner to change, and expressing gratitude towards each other) collected to answer unrelated research questions.
After the laboratory session, couples filled out other measures unrelated to the current project, including a daily-diary study and a follow-up survey.
One participant did not complete the background survey and four did not complete the lab survey—these participants were retained to study physiology.
To allow for more direct comparison of IBI and SCL with RSA, we examined synchrony when IBI (B = 0.00, SE = 0.03, 95% CI [− 0.06, 0.05], t(2230) = − 0.15, p = .88) and SCL (B = 0.10, SE = 0.04, 95% CI [0.04, 0.17], t(2170) = 2.99, p < .01) were binned at 30 s and found consistent results. We also created 60-s bins for RSA, for readers concerned about our 30-s RSA bins, and found consistent results (B = − 0.05, SE = 0.07, 95% CI [− 0.19, 0.08], t(52.69) = − 0.78, p = .44).
Gay couples (N = 2) were randomly assigned roles as man or woman. To ensure their assignment had no effect, we replicated the results when switching the assigned gender roles and excluding gay couples (see Supplemental Table S3).
