Parent-child synchrony, the coupling of behavioral and biological signals during social contact, may fine-tune the child's brain circuitries associated with emotional bond formation and the child's development of emotion regulation. Here, we examined the neurobiological underpinnings of these processes by measuring parent's and child's prefrontal neural activity concurrently with functional near-infrared spectroscopy hyperscanning. Each child played both a cooperative and a competitive game with the parent, mostly the mother, as well as an adult stranger. During cooperation, parent's and child's brain activities synchronized in the dorsolateral prefrontal and frontopolar cortex (FPC), which was predictive for their cooperative performance in subsequent trials. No significant brain-to-brain synchrony was observed in the conditions parent-child competition, stranger-child cooperation and stranger-child competition. Furthermore, parent-child compared to stranger-child brain-to-brain synchrony during cooperation in the FPC mediated the association between the parent's and the child's emotion regulation, as assessed by questionnaires. Thus, we conclude that brain-to-brain synchrony may represent an underlying neural mechanism of the emotional connection between parent and child, which is linked to the child's development of adaptive emotion regulation. Future studies may uncover whether brain-to-brain synchrony can serve as a neurobiological marker of the dyad's socio-emotional interaction, which is sensitive to risk conditions, and can be modified by interventions. •Brain activities of parent and child synchronize during cooperation.•No significant brain-to-brain synchrony for stranger-child dyads.•Parent-child brain-to-brain synchrony predicts cooperative performance.•Parent-child brain-to-brain synchrony is linked to child's emotion regulation.

Against the background of very limited evidence, the present study aimed to prospectively examine the impact of maternal postpartum post-traumatic stress disorder (PTSD) symptoms on four important areas of child development, i.e. gross motor, fine motor, communication and social-emotional development. This study is part of the large, population-based Akershus Birth Cohort. Data from the hospital's birth record as well as questionnaire data from 8 weeks and 2 years postpartum were used (n = 1472). The domains of child development that were significantly correlated with PTSD symptoms were entered into regression analyses. Interaction analyses were run to test whether the influence of postpartum PTSD symptoms on child development was moderated by child sex or infant temperament. Postpartum PTSD symptoms had a prospective relationship with poor child social-emotional development 2 years later. This relationship remained significant even when adjusting for confounders such as maternal depression and anxiety or infant temperament. Both child sex and infant temperament moderated the association between maternal PTSD symptoms and child social-emotional development, i.e. with increasing maternal PTSD symptom load, boys and children with a difficult temperament were shown to have comparatively higher levels of social-emotional problems. Examining four different domains of child development, we found a prospective impact of postpartum PTSD symptoms on children's social-emotional development at 2 years of age. Our findings suggest that both boys and children with an early difficult temperament may be particularly susceptible to the adverse impact of postpartum PTSD symptoms. Additional studies are needed to further investigate the mechanisms at work.

While ample research exists about mother-child attachment, so far little focus has been on specifics of father-child attachment. Even less research is available on the nature of the father-child relationship for children born preterm. The objective of this study was to determine whether children born preterm (23 to 37 weeks gestation) differ in their attachment to their fathers and mothers from their term peers (> 37 weeks gestation), and whether specific child characteristics, such as gender, twin status, and developmental status, have an influence on the parent-child relationship. The sample consisted of 290 children (n = 140 girls, 48.28%), 190 born before term (including 45 twin pairs) between 12 and 36 months of age (M = 19.5, SD = 5.7) and 100 term children of the same age (M = 18.8, SD = 6.1) with their 245 fathers and mothers. Attachment of the children with their mothers and fathers was assessed using the Attachment Q-sort during two home visits. Children's developmental status was measured with the Bayley Scales of Infant and Toddler Development. Within a multigroup analysis of parents with children born preterm and at term more secure attachment was found for both parents in the term sample than in the preterm group. Correlates of attachment specific to fathers of children born preterm accumulated to an explained variance of R2 = .82. For those fathers, less education as well as lower development scores and male gender of the child were associated with lower attachment scores. In the three other parent-child constellations the explained variance did not exceed 20%. Child development proved to be a significant predictor for father-child attachment regardless of the child's birth status. Male gender was associated with lower attachment scores for children born preterm with either parent. The findings highlight the importance of including fathers in research and clinical practice and informing them about preterm birth, possible problems, and developmental consequences as well. Health professionals should be advised to create interventions focusing on both parents to enhance the quality of attachment in parent-child dyads in children born preterm.

Background Children born very preterm (VPT; <32 weeks’ gestation) are at high risk of neurodevelopmental and behavioural difficulties associated with atypical brain maturation, including socio-emotional difficulties. The analysis of large-scale brain network dynamics during rest allows us to investigate brain functional connectivity and its association with behavioural outcomes. Methods Dynamic functional connectivity was extracted by using the innovation-driven co-activation patterns framework in VPT and full-term children aged 6–9 to explore changes in spatial organisation, laterality and temporal dynamics of spontaneous large-scale brain activity (VPT, n  = 28; full-term, n  = 12). Multivariate analysis was used to explore potential biomarkers for socio-emotional difficulties in VPT children. Results The spatial organisation of the 13 retrieved functional networks was comparable across groups. Dynamic features and lateralisation of network brain activity were also comparable for all brain networks. Multivariate analysis unveiled group differences in associations between dynamical functional connectivity parameters with socio-emotional abilities. Conclusion In this exploratory study, the group differences observed might reflect reduced degrees of maturation of functional architecture in the VPT group in regard to socio-emotional abilities. Dynamic features of functional connectivity could represent relevant neuroimaging markers and inform on potential mechanisms through which preterm birth leads to neurodevelopmental and behavioural disorders. Impact Spatial organisation of the retrieved resting-state networks was comparable between school-aged very preterm and full-term children. Dynamic features and lateralisation of network brain activity were also comparable across groups. Multivariate pattern analysis revealed different patterns of association between dynamical functional connectivity parameters and socio-emotional abilities in the very preterm and full-term groups. Findings suggest a reduced degree of maturation of the functional architecture in the very preterm group in association with socio-emotional abilities.

Strength and vulnerability integration (SAVI) is a theoretical model that predicts changes in emotional experience across adulthood. A growing number of studies find that as people age, they become more adept at using thoughts and behaviors to avoid or mitigate exposure to negative experiences. People gradually acquire this expertise over a lifetime of experiences and are more motivated to regulate their emotions because of perceptions of time left to live. SAVI further posits that aging is associated with physiological vulnerabilities that make regulating high levels of emotional arousal more difficult. In situations in which people experience high levels of distress, age differences that normally favor older adults in the use of emotion-regulation strategies will be attenuated (and may even be nullified or reversed), and the physiological consequences of sustained emotional arousal will be more costly for older adults. In this article, we describe SAVI and discuss recent studies supporting its predictions.

This research aims to investigate the salience of mothers’ emotional expressivity and its links with adolescents’ emotional wellbeing and expressivity in an urban society endorsing more individualism and a rural society ascribing to more collectivism. By comparing Chinese urban ( N = 283, M age = 14.13) and rural ( N = 247, M age = 14.09) adolescents, this research found that urban mothers’ expression of positive-dominant and positive-submissive emotions (PD and PS) were more common while expression of negative-dominant (ND) emotions was less common than rural mothers’. PD and PS had significant links with urban and rural adolescents’ increased emotional expressivity and self-esteem, however, only significantly related to urban adolescents’ decreased depression but not with rural adolescents’. ND had significant links with both urban and rural adolescents’ expression of negative emotions, however, only significantly correlated with urban adolescents’ less level of self-esteem and rural adolescents’ more expression of positive emotions. No significant difference was found in the salience of urban and rural mothers’ expression of negative-submissive (NS) emotions, which positively related to both urban and rural adolescents’ depression and emotional expressivity. Moreover, we found that adolescents’ emotional wellbeing (i.e., self-esteem and depression) mediated the relationship between mothers’ emotional expressivity and adolescents’ expressivity in both societies. Overall, the study findings document that the salience of mothers’ emotional expressivity and its relations with adolescents’ emotional adjustment differ between urban and rural societies.

The following article deals with emotional development and the development of emotion regulation skills in children during early childhood education, focusing primarily on the importance of the early childhood teacher. Emotion regulation is important for success and wellbeing in further life. It is developed in interaction with parents as attachment figures. Teachers can also be important persons for the child in the context of bonding. This leads to the question of how early childhood teachers can support children learning to regulate their emotions. We analyze with the content analysis, four programs for promoting social and emotional skills that are currently used in Germany. The main question is if the programs include elements that increase teachers’ skills in supporting the children in regulating their emotions. The categories to analyze the programs are derived from theories of teacher-child interaction. In addition to programs for promoting emotional and social development, we will discuss aspects of shaping interaction as essential elements in promoting emotion regulation. The conclusion outlines some key implications for educational practice and the importance of developing professional behavior for qualitative teacher-child interactions.

Objectives This longitudinal population study aimed to investigate if maternal depression at different time points during the perinatal period impacts children’s social-emotional development at 2 years of age. Methods Participants were women (n = 1235) who gave birth at Akershus University Hospital in Norway. Maternal depressive symptoms were assessed by using the Edinburgh Postnatal Depression Scale at pregnancy week 32 and at 8 weeks and 2 years postpartum, whereas children’s social-emotional development at the age of 2 years was assessed by using the Ages and Stages Questionnaire: Social-Emotional. Bi- and multivariate logistic regression analyses were conducted to examine the linkage between maternal perinatal depression and children’s early social-emotional development. Results Multivariate analyses showed that social-emotional problems in the child 2 years after birth were strongly associated with maternal depression at pregnancy week 32 (adjusted odds ratio (aOR) 3.4; 95 % CI 1.4–8.0), depression at 8 weeks postpartum (aOR 3.8; 95 % CI 1.7–8.6), and with depression at both time points (aOR 3.7; 95 % CI 1.5–10.1). Conclusion Findings indicate pre- and postnatal depression each bears an independent, adverse impact on children’s social-emotional development.

Background:: Nighttime fears are common among school-aged children and may be linked to psychological difficulties, while coping strategies may vary and affect their emotional well-being. This study aimed to identify patterns of nighttime fears and coping styles in school-aged children using Latent Profile Analysis. Subsequently, possible predictors of the latent profiles were tested through multinomial logistic regression analysis. Method:: A sample of 786 Spanish-speaking children (aged 8 to 12; = 9.66, = 1.20; 51.3% girls) participated and completed self-report measures of nighttime fears and coping responses. Results:: The results revealed four latent profiles: (1)“low fears, low self-control” (24.2%), (2)“high fears (except for imaginary fears), maladaptive coping” (22.8%), (3)“moderate fears, adaptive coping” (44.9%), and (4)“high fears, maladaptive coping” (8.1%). The regression analysis revealed that sociodemographic characteristics and children’s perceived helpfulness of coping strategies were predictors of the latent profiles. Conclusions:: These findings suggest the presence of distinct patterns and heterogeneous subgroups, which may emerge as higher or lower risk profiles. It highlights the need to consider the existing patterns to provide tailored interventions targeting nighttime fears.

The oxytocin system is involved in human social behavior and social cognition such as attachment, emotion recognition and mentalizing (i.e. the ability to represent mental states of oneself and others). It is shaped by social experiences in early life, especially by parent–infant interactions. The single nucleotid polymorphism rs53576 in the oxytocin receptor (OXTR) gene has been linked to social behavioral phenotypes. In 195 adult healthy subjects we investigated the interaction of OXTR rs53576 and childhood attachment security (CAS) on the personality traits “adult attachment style” and “alexithymia” (i.e. emotional self-awareness), on brain structure (voxel-based morphometry) and neural activation (fMRI) during an interactive mentalizing paradigm (prisoner's dilemma game; subgroup: n=163). We found that in GG-homozygotes, but not in A-allele carriers, insecure childhood attachment is - in adulthood - associated with a) higher attachment-related anxiety and alexithymia, b) higher brain gray matter volume of left amygdala and lower volumes in right superior parietal lobule (SPL), left temporal pole (TP), and bilateral frontal regions, and c) higher mentalizing-related neural activity in bilateral TP and precunei, and right middle and superior frontal gyri. Interaction effects of genotype and CAS on brain volume and/or function were associated with individual differences in alexithymia and attachment-related anxiety. Interactive effects were in part sexually dimorphic. The interaction of OXTR genotype and CAS modulates adult personality as well as brain structure and function of areas implicated in salience processing and mentalizing. Rs53576 GG-homozygotes are partially more susceptible to childhood attachment experiences than A-allele carriers. •A gene-by-environment interaction was investigated in healthy adults (n=195).•Rs53576 and childhood attachment security (CAS) jointly modulated alexithymia.•Interaction of rs53576 and CAS was sexually dimorphic for attachment-related anxiety.•Interaction modulated structure and function of brain areas related to mentalizing.•GG-homozygotes of rs53576 were partly more susceptible to CAS than A-allele carriers.
