We examined interactions between baseline hypothalamic–pituitary–adrenal (HPA) axis and parasympathetic nervous system (PNS) activity in relation to executive functions (EF) in a sample (n = 1,005) of children in low wealth, nonurban communities at age 48 months. Salivary cortisol and respiratory sinus arrhythmia (RSA) represented baseline HPA axis and PNS activity, respectively. The interaction between RSA and cortisol predicted EF such that children with either lower RSA and lower cortisol, or higher RSA and higher cortisol had higher EF scores. These findings suggest a potential compensatory relation in which the PNS and HPA axis counterbalance each other to support cognition.  相似文献

Seventy-eight postinstitutionalized (PI) children adopted at ages 17–36 months were assessed 2, 8, 16, and 24 months postadoption on measures of cortisol and parenting quality, and compared to same-aged children adopted from foster care (FC, n = 45) and nonadopted children (NA, n = 45). In kindergarten (Mage = 6.0 years), teachers, parents, and trained observers completed measures of peer relationships and attention deficit hyperactivity disorder (ADHD) symptoms. PI children had more peer problems and ADHD symptoms according to teachers and observers than NA children with FC children in between, whereas both PI and FC children were at significantly greater risk of hypocortisolism (i.e., blunted cortisol diurnal rhythm and reactivity). Hypocortisolism and ADHD symptoms mediated the association between preadoption adversity and peer difficulties. Higher postadoption parenting quality was protective.  相似文献

Child hypothalamic pituitary adrenal (HPA) activity was investigated as a moderator of parental depressive symptom effects on child behavior in an adoption sample (n = 210 families). Adoptive parents' depressive symptoms and child internalizing and externalizing were assessed at 18, 27, and 54 months, and child morning and evening HPA activity measured through salivary cortisol at 54 months. Children's daily cortisol levels and day‐to‐day variability were tested as moderators of longitudinal associations between parent and child symptoms at within‐ and between‐family levels. Mothers' symptoms related directly to child internalizing, but child evening cortisol moderated effects of fathers' symptoms on internalizing, and of both parents' symptoms on externalizing. Different paths of within‐family risk dynamics versus between‐family risk synergy were found for internalizing versus externalizing outcomes.  相似文献

This study examined the associations among maternal depression, mothers’ emotional and material investment in their child, and children's cognitive functioning. Middle-class Chilean mothers and children (N = 875; 52% males) were studied when children were 1, 5, 10, and 16 years (1991–2007). Results indicated that highly depressed mothers provided less emotional and material support to their child across all ages, which related to children's lower IQ. Children with lower mental abilities at age 1 received less learning-material support at age 5, which led to mothers’ higher depression at child age 10. Mothers’ low support was more strongly linked to maternal depression as children got older. Findings elucidate the dynamic and enduring effects of depression on mothers’ parenting and children's development.  相似文献

The association between child temperament characteristics and total diurnal saliva cortisol in 84 children (M = 2.3 years, SD = 0.6) attending out-of-home, center-based child care and 79 children (M = 2.0 years, SD = 0.5) attending at-home parental care was examined. Saliva samples were collected during two consecutive days, that is, Sunday and Monday, with four samples taken per day. While children higher in surgency had higher total diurnal cortisol production, we did not find evidence that temperament moderated the associations between child-care context and total diurnal cortisol. Negative affectivity and effortful control were not related to cortisol output. Our findings suggest that temperamental surgency may be associated with higher total cortisol production in early childhood across child-care settings.  相似文献

This meta-analysis studies the association of pedagogical processes in early childhood care and education with outcomes in two academic domains: language and literacy as well as mathematics. It synthesizes evidence from 17 longitudinal studies in nine European countries with 16,461 children in regular center-based care spanning the period between ages 3 and 16. Results of a three-level meta-analysis provided small overall effect sizes for both global and domain-specific process quality, and indicated lasting associations with academic development over children’s school career (ES = .11, Cohen’s d = .22, and ES = .10, Cohen’s d = .20). Effects varied by outcome domain, type of process measure, and differences in adopted analyses, with important implications for pedagogical practice and future research.  相似文献

Utilizing a longitudinal sample of Finnish children (ages 6–10), two studies examined how early linguistic (spoken vs. written) and spatial skills predict later development of arithmetic, and whether counting sequence knowledge mediates these associations. In Study 1 (N = 1,880), letter knowledge and spatial visualization, measured in kindergarten, predicted the level of arithmetic in first grade, and later growth through third grade. Study 2 (n = 378) further showed that these associations were mediated by counting sequence knowledge measured in first grade. These studies add to the literature by demonstrating the importance of written language for arithmetic development. The findings are consistent with the hypothesis that linguistic and spatial skills can improve arithmetic development by enhancing children's number‐related knowledge.  相似文献

Family assistance (helping the family) is associated with both positive and negative psychological and biological outcomes during adolescence. However, the association between family assistance and the hypothalamic–pituitary–adrenal (HPA) axis remains unstudied. Thus, we assess how helping the family relates to adolescents’ diurnal cortisol, an index of HPA activity, and psychological outcomes. Three hundred and seventy ethnically diverse adolescents (ages 11–18) reported daily helping behaviors and psychological experiences for 14 days and provided four saliva samples per day for 4 days. Multilevel modeling revealed that cortisol awakening response was lower the day after adolescents helped their families more. This association was explained, in part, by perceived role fulfillment (feeling like a good son, daughter, and sibling). Results highlight a possible psychological and biological benefit of assisting the family during adolescence.  相似文献

This study examined the effects of daily parental autonomy support on changes in child behavior, family environment, and parental well-being across 3 weeks during the COVID-19 pandemic in Germany. Day-to-day associations among autonomy-supportive parenting, parental need fulfillment, and child well-being were also assessed. Parents (longitudinal N = 469; Mage = 42.93, SDage = 6.40) of school children (6–19 years) reported on adjustment measures at two measurement occasions and completed up to 21 daily online questionnaires in the weeks between these assessments. Results from dynamic structural equation models suggested reciprocal positive relations among autonomy-supportive parenting and parental need fulfillment. Daily parental autonomy support, parental need fulfillment, and child well-being partially predicted change in adjustment measures highlighting the central role of daily parenting for children’s adjustment during the pandemic.  相似文献

Are mother–child conflict discussions shaped by time-varying, reciprocal influences, even after accounting for stable contributions from each individual? Mothers were filmed discussing a conflict for 5 min, separately with their younger (ages 5–9, N = 217) and older (ages 7–13, N = 220) children. Each person’s conflict constructiveness was coded in 20-s intervals and data were analyzed using dynamic structural equation modeling, which separates individual and influence effects. Children influenced their mothers’ behavior under certain conditions, with evidence for developmental differences in the magnitude and direction of influence, whereas mothers did not influence their children under any circumstance. Results are discussed in the context of child effects on parent behavior and changes in parenting across middle childhood.  相似文献

Two recently published meta-analyses (Huang, 2012, Hulleman et al., 2010) have focused on the association between achievement goals and achievement outcomes. These meta-analyses differed to some extent, e.g., regarding the identified moderators. The present meta-analysis serves to clarify those heterogeneous findings by considering more studies through 2011 and by considering more moderators. Our literature search identified 180 publications (N = 81 947). Analyses (using random effects models) revealed small but significant associations between achievement goals and achievement outcomes (r = −.12 to r = .13; all ps < .01; global performance goals: r = .01, p > .05). The results of the present moderator analyses differed from those of the previous meta-analyses. For example, in contrast to Huang (2012), we were able to find several moderators of the association between performance-approach goals and academic achievement. The results have several important implications, especially regarding the assessment of achievement goals.  相似文献

Parasympathetic regulation and maternal overprotective parenting were examined in 101 children as moderators of links between preschool (M = 3.53 years) social wariness and childhood (M = 9.07 years) internalizing and anxiety problems, social skills, and scholastic performance. Across these three domains of functioning, more socially wary children were likely to manifest worse adjustment when they had low respiratory sinus arrhythmia (RSA) or highly overprotective mothers. Conversely, maternal overprotection appeared to confer benefits for preschoolers with low wariness and low RSA. These findings point to the importance of both internal self‐regulatory capacities and external support for autonomy and competence to understand and assist socially wary children and their families.  相似文献

This study conducted two meta-analyses to synthesize the association between children’s language skills and two broad-band dimensions of psychopathology: internalizing and externalizing. Pooled estimates across 139 samples (externalizing k = 105; internalizing k = 90) and 147,305 participants (age range: 2–17 years old; mean % males: 53.75; mean % White participants: 55.59; mean % minority participants: 43.12) indicated small but significant associations between child language skills and externalizing problems (Hedges’ g = .22) and between language skills and internalizing problems (Hedges’ g = .23). The association between language difficulties and externalizing problems was stronger amongst males and in children with low versus high sociodemographic risk. Implications of the results for theory and practice are discussed.  相似文献

Children, mothers, and fathers in 12 ethnic and regional groups in nine countries (N = 1,338 families) were interviewed annually for 8 years (Mage child = 8–16 years) to model four domains of parenting as a function of child age, puberty, or both. Latent growth curve models revealed that for boys and girls, parents decrease their warmth, behavioral control, rules/limit-setting, and knowledge solicitation in conjunction with children’s age and pubertal status as children develop from ages 8 to 16 across a range of diverse contexts, with steeper declines after age 11 or 12 in three of the four parenting domains. National, ethnic, and regional differences and similarities in the trajectories as a function of age and puberty are discussed.  相似文献

This study used a large (N = 519), longitudinal sample of adoptive families to test overreactive parenting as a mediator of associations between parental depressive symptoms and early childhood externalizing, and parents’ social support satisfaction as a moderator. Maternal parenting (18 months) mediated the association between maternal depressive symptoms (9 months) and child externalizing problems (27 months). Paternal parenting was not a significant mediator. Unexpectedly, we found a cross-over effect for the moderating role of social support satisfaction, such that partners’ social support satisfaction reduced the strength of the association between each parent's own depressive symptoms and overreactive parenting. Results point to the importance of accounting for broader family context in predicting early childhood parenting and child outcomes.  相似文献

The data combine objectively measured sleep and thrice‐daily salivary cortisol collected from a 4‐day diary study in a large Midwestern city with location data on all violent crimes recorded during the same time period for N = 82 children (Mage = 14.90, range = 11.27–18.11). The primary empirical strategy uses a within‐person design to measure the change in sleep and cortisol from the person's typical pattern on the night/day immediately following a local violent crime. On the night following a violent crime, children have later bedtimes. Children also have disrupted cortisol patterns the following morning. Supplementary analyses using varying distances of the crime to the child's home address confirm more proximate crimes correspond to later bedtimes.  相似文献

Spatial context supports memory retrieval in adults. To understand the development of these effects, context effects on object recognition were tested in neurotypical children ages 3 years to adulthood (n 3–6 years = 34, n 10–16 years = 32, n college age = 22) and individuals with Down syndrome (DS) ages 10–29 years (n = 21). Participants engaged in an object recognition task; objects were presented in scenes and either remained in that same scene or were removed at test. In some groups (< 4.5 years and with DS) context effects were present even though object recognition was poor. After 4.5 years, children demonstrated memory flexibility, while later in adolescence context effects reemerged, showing nonlinearity in the development of these effects.  相似文献

This meta-analysis tested maternal responsivity as a mediator of the association between socioeconomic risk and children's preschool language abilities. The search included studies up to 2017 and meta-analytic structural equation modeling, allowed us to examine the magnitude of the indirect effect across 17 studies (k = 19). The meta-analysis included 6433 predominantly White, English speaking children (Mage = 36 months; 50% female) from Western, industrialized countries. All paths in the model were statistically significant, notably, the indirect effect was significant (b = −.052), showing that maternal responsivity may be a proximal intervening variable between socioeconomic risk and children's language development. Moderator analyses found that the indirect effect was stronger for sensitive parenting than warmth and when parenting was assessed in the family home.  相似文献

We reviewed nine studies in which children's cortisol levels at center daycare were assessed. Our first hypothesis, concerning intraindividual differences in cortisol levels across home and daycare settings, was also tested in a meta-analysis. Our main finding was that at daycare children display higher cortisol levels compared to the home setting. Diurnal patterns revealed significant increases from morning to afternoon, but at daycare only. The combined effect size for seven pertinent studies (n = 303) was r = .18 (CI .06–.29, p = .003). We examined all papers on possible associations between cortisol levels and quality of care, and the influences of age, gender, and children's temperament. Age appeared to be the most significant moderator of this relation. It was shown that the effect of daycare attendance on cortisol excretion was especially notable in children younger than 36 months. We speculate that children in center daycare show elevated cortisol levels because of their stressful interactions in a group setting.  相似文献

This meta-analysis investigated the link between lying and theory-of-mind (ToM) by integrating findings from 81 studies involving 7,826 children between 2 and 14 years of age from 14 different collectivist and individualist cultures. Overall, there was a small, significant positive association (r = .23). Four main moderators were examined: facet of lying (understanding, instigated production, spontaneous production, maintenance); valence of lies (antisocial, prosocial); type of ToM (first-order, second-order); and culture (collectivist, individualist). Facet of lying and type of ToM were significant moderators. ToM was positively related to all facets of lying, but most strongly linked to lie maintenance and weakest for spontaneous production. Both first-order and second-order ToM were positively related to lying, but the link was stronger for the former.  相似文献
