Although emotionally well-regulated children are more likely to behave prosocially, the psychological processes that connect their emotion regulation abilities and prosocial behavior are less clear. We tested if other-oriented sympathy and trust mediated the links between emotion regulation capacities (i.e., resting respiratory sinus arrhythmia [RSA], negative emotional intensity, and sadness regulation) and prosocial behavior in an ethnically diverse sample of 4- and 8-year-olds (N = 131; 49% g

This study examined how coparenting and firstborn children's temperament predicted children's cooperative behavior in response to maternal requests for assistance in the care of a 1-month-old infant sibling. Children's cooperative responding was observed during a diaper change session for 216 firstborns (ages 13 to 70 months; M = 32). Parents also completed questionnaires assessing coparenting and children's temperament. Results suggested that coparenting quality moderated the association betwee

A developmental cascade model was tested to examine longitudinal associations among firstborn children's aggression, theory of mind (ToM), and antagonism toward their younger sibling during the 1st year of siblinghood. Aggression and ToM were assessed before the birth of a sibling and 4 and 12 months after the birth, and antagonism was examined at 4 and 12 months in a sample of 208 firstborn children (initial Mage = 30 months, 56% girls) from primarily European American, middle-class families. F

Neural stem cells (NSCs) have been suggested as a groundbreaking solution for stroke patients because they have the potential for self-renewal and differentiation into neurons. The differentiation of NSCs into neurons is integral for increasing the therapeutic efficiency of NSCs during inflammation. Apoptosis signal-regulating kinase 1 (ASK1) is preferentially activated by oxidative stress and inflammation, which is the fundamental pathology of brain damage in stroke. ASK1 may be involved in the

This study investigated whether Korean mothers’ emotion socialization beliefs are related to emotional functioning in children differing across gender. We interviewed Korean mothers (N = 100) of first graders (55 boys; 45 girls) about their sensitivity, their reactions to children’s distress, and children’s emotion regulation. Two components of emotion regulation were distinguished: regulation and negativity. Results revealed that mothers’ proactive sensitivity and their supportive reactions wer

Proactive and reactive aggression subtypes are distinguishable as early as the preschool years. However, their early physiological and social-emotional correlates have not been examined simultaneously. We tested whether children's skin conductance level, anger regulation, and trust in others were differentially related to their proactive and reactive aggression. Four-year-olds and their primary caregivers were recruited from a large Canadian city (N = 150). Controlling for reactive aggression, h

The current study examined (1) cross-cultural variations in mothers’ reports of how they would react to their children’s positive and negative emotions as triggered by different interpersonal situations and (2) their relations to children’s emotion regulation competence in Nepal, Korea, and Germany. Participants were 305 mothers whose children were first graders in elementary school. Mothers reported their reactions to children’s positive and negative emotions in hypothetical social scenarios an

Abstract 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 discipl

Microglia regulate the secretion of various immunomediators in central nervous system diseases. Microglial autophagy is the crucial process for cell’s survival and cytokine productions. Recent studies have reported that several microRNAs are involved in the autophagy system. miR-Let7A is such a microRNA that plays a role in various inflammation responses, and is magnified as a key modulator particularly in the autophagy system. In present study, we investigated whether miR-Let7A is involved in a

Ischemic stroke results in the diverse phathophysiologies including blood brain barrier (BBB) disruption, brain edema, neuronal cell death, and synaptic loss in brain. Vitamin C has known as the potent anti-oxidant having multiple functions in various organs, as well as in brain. Dehydroascorbic acid (DHA) as the oxidized form of ascorbic acid (AA) acts as a cellular protector against oxidative stress and easily enters into the brain compared to AA. To determine the role of DHA on edema formatio

This study investigated the relationship between traumatic life stress, trust, and prosocial behavior as a positive mental health outcome in Syrian refugee children in Canada. Trust is a resilience factor shown to promote adjustment after resettlement. The specific goals of the study were to test the influence of refugee children’s traumatic life stress on their prosocial behavior and the mediating role of trust in this link. Five- to 12-year-old Syrian refugee children ( N = 124) and their care

Caregiver sensitivity builds a basis for children's sense of security and effective emotion regulation during their development. Applying a cross-cultural lens, caregiver sensitivity can be divided into two subtypes, reactive and proactive, and its prevalence and meaning may differ across cultures. Guided by the theoretical frameworks of developmental niche and parental ethnotheories, the current study examines culture-specific meanings of caregiver sensitivity across five countries: India, Nepa

Leptin is a 16 kDa protein which consists of 167 amino acids. Leptin is considered as one of the adipokines, secretedby white adipocytes, and is the product of the obese (ob) gene. Recently, leptin is recognized as the immuno-stimulatorwhich belongs to the same class of long chain helical cytokines such as interleukin (IL)-6. Leptin is related to the immuneresponses evoked by Mycobacterium tuberculosis infection. Thus, studies of association between immunomoleculesincluding leptin and tuberculos
