Stress due to discrimination may contribute to physiological dysregulation and health risk during the postnatal period. This study examined longitudinal associations between gender discrimination and women’s cortisol responses to subsequent stress. Mothers ( N = 79) reported gender discrimination and completed mother-infant stress tasks with saliva sampling for cortisol at 6, 12, and 18 months postnatal. Multilevel modeling results indicated more overall gender discrimination was associated with higher cortisol. Changes in gender discrimination were not associated with cortisol over time. Gender discrimination may be a factor in women’s postnatal stress and associated health risk via the sensitization of physiological stress responses.

The present study used functional magnetic resonance imaging to investigate how a mother’s experience of neglect in her own childhood is associated with her neural response to her infant’s distress cues. During scanning, 22 high-risk primiparous mothers were exposed to both their own 18-month-old infant’s cry sound and a control sound. Mothers’ continuous Neglect subscale scores from the Childhood Trauma Questionnaire were examined as a predictor of their neural response to own infant cry > control sound. Mothers who reported high levels of neglect from childhood showed regions of hyperactivation to their infant’s cry (relative to control sound) in the anterior and posterior cingulate cortices and insula as well as specific prefrontal (precentral gyrus) and parietal (posterior supramarginal gyrus) areas. These results may suggest how important early life experiences are for future parenting responses and behaviors.

This study investigated the effects of dispositional and experimentally induced perspective-taking (PT) on physiological attunement between romantic partners during a conflict resolution task. Young adult couples ( N = 103 dyads) rated their trait PT 1 week prior to participating in a conflict resolution session with their romantic partner. Immediately before the conflict task, participants were given one of the following three instructions: to take their partner’s perspective (PT condition), to approach the conflict mindfully (mindfulness condition), or to focus on their own perspective regarding the conflict (control condition). Participants provided four saliva samples over the course of the laboratory session, and the samples were assayed for alpha-amylase to measure autonomic nervous system activity. Multilevel modeling results revealed that couples in the PT condition displayed greater autonomic attunement over the course of the conflict session compared to those in the other conditions. In addition, female partners’ dispositional PT enhanced the effect of the PT induction on couples’ attunement. Furthermore, secondary analyses provided support for the beneficial role of autonomic attunement. Specifically, attunement was decreased by negative conflict behaviors and predicted increased post-conflict negative affect in females. Implications for dyadic functioning and intervention are discussed.

The current study examined interactions among genetic influences and children’s early environments on the development of externalizing behaviors from 18 months to 6 years of age. Participants included 233 families linked through adoption (birth parents and adoptive families). Genetic influences were assessed by birth parent temperamental regulation. Early environments included both family (overreactive parenting) and out-of-home factors (center-based Early Care and Education; ECE). Overreactive parenting predicted more child externalizing behaviors. Attending center-based ECE was associated with increasing externalizing behaviors only for children with genetic liability for dysregulation. Additionally, children who were at risk for externalizing behaviors due to both genetic variability and exposure to center-based ECE were more sensitive to the effects of overreactive parenting on externalizing behavior than other children.

This study tested the extent to which the social-cognitive variables of sociotropy and negative relationship attributions predict physiological stress reactivity to interpersonal conflict among emerging adult romantic partners (N = 125 couples). It was hypothesized that sociotropy and negative relationship attributions would predict increased stress reactivity, indexed by salivary cortisol levels, both independently and inter-actively. Results supported the hypotheses but pointed to more complex and gender-specific relationships; sociotropy predicted higher cortisol during the conflict for men, but this effect was mitigated by causal attributions for negative partner behaviors. For women, causal attributions also tended to lower reactivity in the sense of faster recovery after the conflict event, while responsibility attributions predicted slower recovery and more extended physiological stress.
