Children with specific psychophysiological profiles may be more strongly affected by adverse environmental experiences. Guided by a biopsychosocial perspective, we examined whether infant respiratory sinus arrhythmia (RSA), an index of parasympathetic functioning, moderates the associations between paternal postpartum depression (PPD) symptoms and infants' observed empathy‐related responses. Participants were 142 families with infants (51% female) assessed at two time points. At T1 (3 months of age), fathers reported their depressive symptoms. Infants' cardiac activity was recorded during rest and estimates of RSA were calculated. In addition, infants' empathy‐related responses during a maternal distress simulation were observed and rated at T2 (12 months of age). Higher paternal PPD at T1 predicted higher infant affective (i.e., affective concern) and cognitive (i.e., inquiring behaviors) responses to maternal distress at T2. Infant RSA moderated this relationship for cognitive responses, with a significant positive association only for children with high or average RSA. These findings contribute to the understanding of the psychophysiological mechanisms that support empathy development. [ABSTRACT FROM AUTHOR]

The COVID‐19 pandemic may impact the development of infants' social communication patterns with their caregivers. The current study examined continuity, stability, and bidirectional associations in maternal and infant dyadic Emotional Availability (EA) before and during the COVID‐19 pandemic. Participants were 110 Israeli mother‐infant dyads (51% girls) that were assessed prior to (Mage = 3.5 months) and during (Mage = 12.4 months) the pandemic. At both time points, mother‐infant interactions were observed during play (nonstressful context) and tasks designed to elicit infant frustration (stressful context). Maternal and child EA were coded offline. Maternal EA demonstrated no significant mean‐level changes from before to during the COVID‐19 pandemic, whereas infant responsiveness and involvement increased over time. Stability and bidirectional associations in EA differed by context and were evident only in the stressful context. Mothers' perceived levels of social support further moderated these associations. Specifically, infants' pre‐pandemic responsiveness and involvement predicted maternal EA during the pandemic only when mothers reported low levels of social support. Our findings suggest that maternal and child EA were not adversely impacted by the COVID‐19 pandemic. However, patterns of EA demonstrated moderate‐to‐no stability over time, suggesting considerable individual differences in trajectories of EA. [ABSTRACT FROM AUTHOR]

Exposure to maternal depressive symptoms (MDS) may have a pertinent role in shaping children's emotional development. However, little is known about how these processes emerge in the early postpartum period. The current study examined the direct and interactive associations between MDS and cry-processing cognitions in the prediction of infant negative emotionality and affective concern. Participants were 130 mother-child dyads (50% female) assessed at three time points. During the second trimester of pregnancy, expectant mothers completed a procedure to assess responses to video clips of distressed infants and reported about MDS. Mothers also reported about MDS at 1- and 3-months postpartum. At age 3 months, infants' negative emotionality and affective concern responses were observed and rated. We found no direct associations between MDS and both measures of infant emotional reactivity. However, MDS interacted with cry-processing cognitions to predict affective concern and negative emotionality. Overall, MDS were related to increased affective concern and decreased negative emotionality when mothers held cognitions that were more focused on their own emotions in the face of the infant's cry rather than the infant's emotional state and needs. Clinical implications for early screening and intervention are discussed.
