“…In addition to momentary parent-child interaction quality, the long-term relationship quality also seems to influence neural similarity of parent-child dyads. Consistent with prior evidence that positive parent-child relationship quality plays a vital role in increasing shared dyadic process in affect, behavior and physiology (Davis et al, 2018;Han et al, 2019;Birk et al, 2022), a recent study demonstrated that mother-child dyads with greater family connectedness show more similar neural response patterns to stress (Lee et al, 2018). However, other research did not find the link between parent-child attachment quality and inter-brain synchrony during cooperation (Miller et al, 2019).…”

Children and their parents are wired to connect as it provides the foundation for developing children to adapt to an increasingly complex environment. Although extensive studies demonstrate the importance of parent-child dyadic similarity at the behavioral, psychological, and physiological levels in fostering children's learning and psychological wellbeing, little is known about parent-child similarity at the neural level until recently. Drawing on our own work and the work by other scholars, this review summarizes recent advances in empirical research on parent-child neural similarity. Specifically, this review elaborates the theoretical importance of studying parent-child neural similarity and showcases how parent-child neural similarity is assessed using different neuroimaging approaches. We further synthesize empirical evidence about the contextual and individual factors that may contribute to variability in parent-child neural similarity, summarize how such neural similarity is related to different aspects of child adjustment, and highlight important directions for future research. Taken together, we hope that this integrative review can demonstrate cutting-edge research that explores neural similarity in parent-child dyads, and provide researchers with a clear roadmap to examine parent-child neural similarity in order to gain a better understanding of parental socialization process and brain development.

“… 22 , 23 , 27 Prior studies of parent-child dyads have found that in the context of negative environmental factors, physiologic synchrony may be associated with greater physiologic stress and maladaptive patterns of self-regulation or relational patterns in the dyad. 50 , 51 This could mean that clinical interventions for stress reduction in either parents or children may have mutual physiological benefits for both. From a policy perspective, this also underscores the potential physiologic and health benefits of targeting approaches that support both individual social needs and population-level social conditions.…”
Background Mothers and their children demonstrate dyadic synchrony of hypothalamic–pituitary–adrenal (HPA) axis function, likely influenced by shared genetic or environmental factors. Although evidence has shown that chronic stress exposure has physiologic consequences for individuals—including on the HPA axis—minimal research has explored how unmet social needs such as food and housing instability may be associated with chronic stress and HPA axis synchrony in mother–child dyads. Methods We conducted a secondary analysis of data from 364 mother–child dyads with low-income recruited during a randomized trial conducted in an urban pediatric clinic. We used latent profile analysis (LPA) to identify subgroups based on naturally occurring patterns of within-dyad hair cortisol concentration (HCC). A logistic regression model predicted dyadic HCC profile membership as a function of summative count of survey-reported unmet social needs, controlling for demographic and health covariates. Results LPA of HCC data from dyads revealed a 2-profile model as the best fit. Comparisons of log HCC for mothers and children in each profile group resulted in significantly “higher dyadic HCC” versus “lower dyadic HCC” profiles (median log HCC for mothers: 4.64 vs 1.58; children: 5.92 vs 2.79, respectively; P < .001). In the fully adjusted model, each one-unit increase in number of unmet social needs predicted significantly higher odds of membership in the higher dyadic HCC profile when compared to the lower dyadic HCC profile (odds ratio = 1.13; 95% confidence interval [1.04-1.23]; P = .01). Conclusion Mother–child dyads experience synchronous patterns of physiologic stress, and an increasing number of unmet social needs is associated with a profile of higher dyadic HCC. Interventions aimed at decreasing family-level unmet social needs or maternal stress are, therefore, likely to affect pediatric stress and related health inequities; efforts to address pediatric stress similarly may affect maternal stress and related health inequities. Future research should explore the measures and methods needed to understand the impact of unmet social needs and stress on family dyads.
“…Synchrony is shaped early in infancy and includes reciprocal gaze and physical touch (Feldman & Eidelman, 2007). As children develop, indicators of dyadic synchrony can be found at the hormonal, physiological, behavioral, and neural level (Birk et al, 2022;Davis et al, 2017Davis et al, , 2018Feldman, 2007Feldman, , 2012, though the vast majority of synchrony work has focused on parent-child PBS (e.g., mutual eye gaze, shared affect).…”

“…Synchrony is a critical component of dynamic parent–child relationships and is associated with self‐regulation development in youth across cultures (Feldman, 2017). A plethora of data supports the link between positive behavioral synchrony (PBS) and healthy adjustment in children (Bell, 2020; Birk et al., 2022; Davis et al., 2017). However, while much less is known about physiological synchrony, preliminary research suggests this process is related to indices of child self‐regulation in complex ways (Davis et al., 2018; DePasquale, 2020).…”
Positive behavioral synchrony (PBS) between mothers and children involves the bidirectional exchange of verbal and nonverbal communication. Respiratory sinus arrhythmia (RSA) synchrony reflects the concordance between mother-child physiological states. Both PBS and RSA synchrony can be undermined by psychopathology symptoms. Latinx and Black families may experience contextual stressors that contribute to heightened symptoms of psychopathology, yet minimal research has examined relations between psychopathology symptoms with PBS and RSA synchrony in these families. The present study assessed associations between maternal depressive and child internalizing symptoms, mother and child negative affect (NA), and PBS and RSA synchrony in a sample of 100 Latina and Black mothers (M age = 34.48 years, SD = 6.39 years) and their children (M age = 6.83 years, SD = 1.50 years). Dyads engaged in a video-recorded stress task where RSA was collected continuously. Videos were later coded for PBS and mother and child NA. Mothers reported on their depressive and child's internalizing symptoms. Maternal NA was associated with weak PBS and negative RSA synchrony. Neither depressive and internalizing symptoms nor child NA were associated with PBS or RSA synchrony. Results highlight the potency of maternal NA on behavioral and physiological synchrony in Latinx and Black families.
