Linking Parent-Adolescent Congruence in Perceived Parental Emotional Support to Adolescent Developmental Outcomes: The More, the Better?

Parents and their children can have congruent or incongruent perceptions of parenting, which has been shown to have downstream effects on certain adolescent outcomes. However, little is known about whether such effect holds for various domains of developmental outcomes or across adolescent boys and girls. Investigating 2268 parent-girl (Mage = 15.73, SDage = 0.29, 75.5% were mothers) and 2090 parent-boy (Mage = 15.75, SDage = 0.29, 71.8% were mothers) dyads from Hong Kong, this study examined the associations between parent-adolescent (in)congruence and adolescent emotional symptoms, positive emotions, and academic performance. Polynomial regression and response surface analyses revealed that both congruence and incongruence were linked to emotional symptoms and positive emotions in varying patterns, but only congruence was tied to academic performance. Associations between (in)congruence and developmental outcomes generally were similar between boys and girls. These findings underscore the importance of decomposing (in)congruence effects in family processes and emphasizing the complexity of adolescent development.

Parental autonomy support and psychological control and children's biobehavioral functioning: Historical cohort differences in urban China.

This study examined parental autonomy support and psychological control and their relations with child biobehavioral functioning. Participants included 238 Chinese parent-child dyads (Mage-child = 8.38 years, 42.0% girls) in two cohorts (2013 and 2021). Parents in the 2021 cohort displayed higher levels of autonomy support and psychological control during the parent-child interaction than in the 2013 cohort. Parental psychological control was positively associated with emotion regulation and negatively associated with externalizing problems in the 2013 cohort, but not in the 2021 cohort. Parental psychological control was also negatively associated with vagal suppression in the 2021 cohort, but not in the 2013 cohort. The result suggests that sociocultural contexts may shape the display of parental behaviors and their significance for child development.

Parenting links to parent-child interbrain synchrony: a real-time fNIRS hyperscanning study.

Parent-child interaction is crucial for children's cognitive and affective development. While bio-synchrony models propose that parenting influences interbrain synchrony during interpersonal interaction, the brain-to-brain mechanisms underlying real-time parent-child interactions remain largely understudied. Using functional near-infrared spectroscopy, we investigated interbrain synchrony in 88 parent-child dyads (Mage children = 8.07, 42.0% girls) during a collaborative task (the Etch-a-Sketch, a joint drawing task). Our findings revealed increased interbrain synchrony in the dorsolateral prefrontal cortex and temporo-parietal areas during interactive, collaborative sessions compared to non-interactive, resting sessions. Linear regression analysis demonstrated that interbrain synchrony in the left temporoparietal junction was associated with enhanced dyadic collaboration, shared positive affect, parental autonomy support, and parental emotional warmth. These associations remained significant after controlling for demographic variables including child age, child gender, and parent gender. Additionally, differences between fathers and mothers were observed. These results highlight the significant association between brain-to-brain synchrony in parent-child dyads, the quality of the parent-child relationship, and supportive parenting behaviors. Interbrain synchrony may serve as a neurobiological marker of real-time parent-child interaction, potentially underscoring the pivotal role of supportive parenting in shaping these interbrain synchrony mechanisms.

Relations among family, peer, and academic stress and adjustment in Chinese adolescents: A daily diary analysis.

Family, peers, and academics are three central sources of stress for Chinese adolescents, which have potential negative implications for youth's adjustment. This study investigated how within-person fluctuations in daily domains of stress (i.e., family, peer, and academic) and between-person differences in average stress levels were associated with four Chinese adolescent adjustment indicators (i.e., positive and negative emotions, sleep quality, and subjective vitality). Participants included 315 Chinese adolescents (48.3% girls; Mage = 13.05 years, SD = 0.77 years) who completed a 10-day diary on each domain of stress and indicators of adjustment. Multilevel models revealed that peer stress had the most detrimental association with Chinese adolescents' adjustment at both within-person (i.e., higher same-day and next-day negative emotions) and between-person (i.e., higher negative emotions, worse sleep quality, and lower subjective vitality) levels. Academic stress was only significant at the between-person level, corresponding to worse sleep quality and increased levels of negative emotions. Family stress exhibited mixed associations and was positively associated with positive and negative emotions and subjective vitality. These findings underscore the need to examine the impact of multiple domains of stress on Chinese adolescent adjustment. Further, identification and intervention for adolescents with elevated peer stress may be particularly helpful for increasing healthy adjustment.

Uranium capture by a layered 2D/2D niobium phosphate/holey graphene architecture via an electro-adsorption and electrocatalytic reduction coupling process.

As an energy-efficient and eco-friendly technique, capacitive deionization (CDI) has shown great potential for uranium (U(VI)) capture recently. However, extracting U(VI) with high kinetics, capacity and selectivity remains a major challenge due to the current surface active sites-based material and co-existing ions in aqueous solution. Here we rationally designed a layered 2D/2D niobium phosphate/holey graphene (HGNbP) electrode material, and originally demonstrated its efficient U(VI) capture ability via an electro-adsorption and electrocatalytic reduction coupling process. The less-accumulative loose layered architecture, open polycrystalline construction of niobium phosphate with active phosphate sites, and rich in-plane nano-pores on conductive graphene nanosheets endowed HGNbP with fast charge/ion transport, high electroconductivity and superior pseudocapacitance, which enabled U(VI) ions first to be electro-adsorbed, then physico-chemical adsorbed, and finally electrocatalysis reduced/deposited onto electrode surface without the limitation of active sites under a low potential of 1.2 V. Based on these virtues, the HGNbP exhibited a fast adsorption kinetics, with a high removal rate of 99.9% within 30 min in 50 mg L-1 U(VI) solution, and a high adsorption capacity up to 1340 mg g-1 in 1000 mg L-1 U(VI) solution. Furthermore, the good recyclability and selectivity towards U(VI) were also realized.
