“…Moreover, with the close proximity and developmental salience of friends at this age, it is possible that the lure of alcohol that a deviant best friend may be able to procure may be a stronger influence than weekly telephone calls from parents. On the other hand, supportive relationships with friends who do not engage in risky behavior can enhance health and reduce stress system activity (Dunbar, 2018; Rankin et al, 2021).…”

Relationships with parents and friends may work together to increase the risk of adjustment problems in emerging adulthood. However, it is still undetermined if social relationships act in an additive (i.e., serve as unique predictors) or moderating (i.e., interact with other predictors) fashion. In a cross-sectional sample of 859 female college students ( M age = 19.53, SD = 1.49; 73.9% White) from a large university in the south-central United States, we assessed how parents and best friends impact emerging adult internalizing symptoms, risky behavior, and health problems. We found that low levels of best friend risky behavior attenuated the links between father-emerging adult relationship quality and risky behavior and internalizing symptoms, and high levels of father-emerging adult relationship quality magnified the association between mother-emerging adult relations and internalizing symptoms. Ultimately, these results indicate that relationships with parents and friends served as additive or unique predictors of emerging adult health and behavior.

“…Although there is a paucity of research assessing progesterone coordination in the context of family relationships, and the role of progesterone has been largely underexplored, previous research has asserted that this hormone may be important for affiliation and social support (Brown, Frederickson et al, 2009b ; Rankin et al, 2021 ; Schultheiss et al, 2004 ). Our findings may provide evidence that progesterone attunement within the parental dyad may be related to mothers’ greater ability to establish adrenocortical attunement with her infant.…”

“…What is clear is that progesterone is associated with social affiliative motives (Brown, Fredrickson, et al, 2009 ; Schultheiss et al, 2004 ). Within the context of a close relationship, progesterone may serve to buffer social stressors and may be an index of perceived social support or closeness (Rankin et al, 2021 ).…”

Objective The vast majority of research on biobehavioral influences on development has focused on mothers and infants, whereas research on paternal biobehavioral influences remains sparse. This study aims to increase understanding of paternal influences on the biobehavioral dynamics of the family unit, using a multi-system approach. Methods Participants consisted of 32 predominantly high-risk families recruited during pregnancy who completed monthly questionnaires and in-home visits when infants were 4, 12, and 18 months of age. In-home visits included semi-structured interaction tasks and saliva samples for cortisol and progesterone assays. Results Mothers and infants, but not fathers and infants, showed adrenocortical attunement, with the strongest attunement at 18 months. Second, mothers’ couple satisfaction did not significantly impact infants’ cortisol levels or mother-infant cortisol attunement, but mothers’ progesterone moderated the relationship between couple satisfaction and infant cortisol levels such that mothers with low couple satisfaction, but high progesterone, had infants with lower cortisol levels. Finally, mothers’ and fathers’ progesterone levels were attuned across the time points. Conclusions This is some of the first evidence of the establishment of the family biorhythm and suggests that fathers play an indirect role in facilitating mother-infant adrenocortical attunement.

Bio-behavioral synchrony is a potential mechanism for mate selection in humans

The decision with whom to form a romantic bond is of great importance, yet the biological or behavioral mechanisms underlying this selective process in humans are largely unknown. Classic evolutionary theories of mate selection emphasize immediate and static features such as physical appearance and fertility. However, they do not explain how initial attraction temporally unfolds during an interaction, nor account for mutual physiological or behavioral adaptations that take place when two people become attracted. Instead, recent theories on social bonding emphasize the importance of co-regulation during social interactions (i.e., the social coordination of physiology and behavior between partners), and predict that co-regulation plays a role in bonding with others. In a speed-date experiment of forty-six heterosexual dates, we recorded the naturally occurring patterns of electrodermal activity and behavioral motion in men and women, and calculated their co-regulation during the date. We demonstrate that co-regulation of behavior and physiology is associated with the date outcome: when a man and a woman synchronize their electrodermal activity and dynamically tune their behavior to one another, they are more likely to be romantically and sexually attracted to one another. This study supports the hypothesis that co-regulation of sympathetic and behavioral rhythms between a man and a woman serves as a mechanism that promotes attraction.
