What's parenting got to do with it: emotional autonomy and brain and behavioral responses to emotional conflict in children and adolescents

Healthy parenting may be protective against the development of emotional psychopathology, particularly for children reared in stressful environments. Little is known, however, about the brain and behavioral mechanisms underlying this association, particularly during childhood and adolescence, when emotional disorders frequently emerge. Here, we demonstrate that psychological control, a parenting strategy known to limit socioemotional development in children, is associated with altered brain and behavioral responses to emotional conflict in 27 at‐risk (urban, lower income) youth, ages 9–16. In particular, youth reporting higher parental psychological control demonstrated lower activity in the left anterior insula, a brain area involved in emotion conflict processing, and submitted faster but less accurate behavioral responses—possibly reflecting an avoidant pattern. Effects were not replicated for parental care, and did not generalize to an analogous nonemotional conflict task. We also find evidence that behavioral responses to emotional conflict bridge the previously reported link between parental overcontrol and anxiety in children. Effects of psychological control may reflect a parenting style that limits opportunities to practice self‐regulation when faced with emotionally charged situations. Results support the notion that parenting strategies that facilitate appropriate amounts of socioemotional competence and autonomy in children may be protective against social and emotional difficulties.     

Human milk cortisol concentration predicts experimentally induced infant fear reactivity: moderation by infant sex

Little consideration has been given to the possibility of human infant development being shaped via lactocrine programming, and by breast milk cortisol levels specifically. Despite animal models indicating that glucocorticoid (GC) exposure via lactation might modify brain development and behavior, only one study has reported that milk cortisol levels were positively associated with infant negative affectivity, especially fearfulness and sadness—early emerging risk factors for internalizing difficulties such as anxiety. The aim of the current study was to investigate whether human milk cortisol is associated with mother‐reported fearfulness and experimentally induced infant fear reactivity. Mother‐infant dyads (n = 65) enrolled in the FinnBrain Cohort Study participated. Breast milk samples were obtained 2.5 months postpartum, and milk cortisol concentrations were ascertained using validated luminescence immunoassay methodology. Infant fear reactivity was assessed using maternal reports 6 months postpartum and in a laboratory 8 months postpartum. There was a significant interaction between infant sex and milk cortisol such that higher milk cortisol was related to higher infant fear reactivity in a laboratory setting in girls (β = 0.36, p = .04) but not in boys (β = ?0.15, p = .40). Milk cortisol was not associated with mother‐reported infant fearfulness. Results suggest that higher human milk cortisol concentrations are associated with elevated experimentally induced fear in infancy. Findings support lactocrine programming, and suggest that mothers may “communicate” vital information about stressful environments via cortisol contained in breast milk, shaping girls' early emotional reactivity.     

Type D personality,but not Type A behavior pattern,is associated with coronary plaque vulnerability

Personality traits are associated with major adverse coronary events (MACE) in patients with coronary artery disease (CAD). However, the link between personality traits and intravascular morphology in CAD patients is poorly understood. This study investigated the relationship between personality traits, specifically Type A behavior pattern and Type D personality, and plaque vulnerability. After adjustment for demographic and clinical factors, multivariable regression analysis showed no association between Type A and optical coherence tomography indices. However, Type D personality was independently associated with lipid plaque, thin cap fibroatheroma (TCFA), and fibrous cap thickness. More specifically, negative affectivity of Type D was related to lipid plaque, TCFA and fibrous cap thickness, and social inhibition was associated with plaque rupture. Our results show that Type D personality was associated with plaque vulnerability, independent of clinical factors. Measurement of negative affectivity and social inhibition will increase our understanding of the progressive phase of the plaque vulnerability, which can contribute to the early identification of high risk patients and reduce the incidence of MACE.     

U.K. consumers' perceived risk of buying products from emerging economies: A moderated mediation model

Although considerable research has been conducted on consumer attitude towards foreign products, most of these studies focus on the attitude of products from Western developed countries. Our study intends to investigate the effects of consumers' national identification and culture sensitivity on their perceived risk of buying products from Eastern developing countries. Especially, this study advances the literature by identifying the mediation effect of consumer ethnocentrism and the moderating effect of consumer value consciousness. Taking China and India as focal emerging economies, the consumer survey (n = 308) in the United Kingdom produced the following results. First, U.K. consumers' national identification is positively related to their perceived risk of buying Eastern products through consumer ethnocentrism, whereas their cultural sensitivity has a negative relationship. Second, the effect of consumer ethnocentrism on the perceived risk of buying Eastern products is moderated by consumer value consciousness. Third, value consciousness also attenuates the indirect relationships between national identification or cultural sensitivity and perceived risk via consumer ethnocentrism.     

Theory‐of‐Mind development and early sibling relationships after the birth of a sibling: Parental discipline matters

This study investigated relations among children's Theory‐of‐Mind (ToM) development, early sibling interactions, and parental discipline strategies during the transition to siblinghood. Using a sample of firstborn children and their parents (N = 208), we assessed children's ToM before the birth of a sibling and 12 months after the birth, and sibling interactions (i.e., positive engagement and antagonism) and parental discipline strategies (i.e., child‐centred and parent‐centred discipline) at 4 and 8 months in the first year of siblinghood. Structural equation modelling analyses revealed that children's ToM before the birth of the sibling predicted children's positive engagement with the infant sibling, whereas children's antagonistic behaviours towards the infant sibling negatively predicted children's ToM at 12 months, but only when mothers used low levels of child‐centred discipline. These findings emphasize the role of parents in the development of young children's social‐cognitive understanding in the context of early sibling interactions.

Highlights

• This study investigated relations among firstborns' Theory‐of‐Mind (ToM), early sibling relationships, and parental discipline during the first year of siblinghood.
• Multigroup analyses showed that ToM predicted higher sibling positive engagement, and early sibling antagonism predicted poorer ToM when mothers used low child‐centred discipline.
• Parental discipline plays an important role in the development of young children's social understanding and sibling relationships as early as the first year of siblinghood.

     

Intersectional experiences of discrimination in a low‐resource urban community: An exploratory latent class analysis

There have been increasing calls for the application of an intersectionality framework to understand and address discrimination and health inequities among diverse communities. Yet there have been theoretical debates regarding to whom intersectionality applies and how intersectional experiences of discrimination are associated with health outcomes. The current study aimed to contribute to these theoretical debates and inform practical applications to reduce health inequities. Data were drawn from a community health survey in New Haven, CT (N = 1,293 adults) and analysed using latent class analysis. Results yielded 4 classes. Members of the 4 classes were similar sociodemographically. Three classes of participants reported experiencing discrimination, and members of these classes had greater stress, higher rates of smoking and sleep disruption, and worse overall health than members of the class reporting no discrimination. Members of 2 classes made multiple, or intersectional, attributions for discrimination, and members of these classes reported the most frequent discrimination. Findings suggest that community members who are sociodemographically similar may have diverse discrimination experiences. Multilevel interventions that address multiple forms of discrimination (e.g., racism and sexism) may hold promise for reducing discrimination and, ultimately, health inequities within low‐resource urban community settings.     

The Role of Ethnic Socialization,Ethnic Identity and Self-Esteem: Implications for Bi-ethnic Adolescents’ School Adjustment

Bi-ethnic adolescents of marriage migrant mothers in Korea are often encouraged to be “pure” Koreans for their adjustments and not given the opportunities to explore their ethnic identity or to learn about their mother’s culture of origin. Existing studies conducted with mono-ethnic minorities in other countries, however, do not support this belief. We tested a conceptual model on the role of ethnic socialization, ethnic identity and self-esteem on school adjustment among bi-ethnic adolescents in Korea based on social identity theory and theoretical models of ethnic socialization and ethnic identity. We used data from 2015 National Survey of Multicultural Families. The study sample consisted of 296 adolescents aged 9–18 who were born between Korean fathers and Vietnamese marriage migrant mothers. We used structural equation modeling to specifically examine the association between ethnic socialization in terms of parents’ linguistic socialization and adolescents’ school adjustment mediated by ethnic identity in the form of ethnic regard and self-esteem among bi-ethnic adolescents. The results verified the hypothesized model, showing positive relationships between linguistic socialization and ethnic regard, ethnic regard and self-esteem, self-esteem and school adjustment, and ethnic regard and school adjustment. Additionally, the results of bootstrapping test showed that the indirect effect of linguistic socialization on self-esteem through ethnic regard was significant. The indirect effect of ethnic regard on school adjustment through self-esteem was significant and the indirect effect of linguistic socialization on school adjustment via ethnic regard and self-esteem was also significant. These results shed light on the important role of ethnic identity fostered at home among bi-ethnic adolescents of marriage migrant mothers in Korea.
