Birth weight interacts with a functional variant of the oxytocin receptor gene (OXTR) to predict executive functioning in children / Mark WADE in Development and Psychopathology, 30-1 (February 2018)  

Public ISBD [article]  inDevelopment and Psychopathology > 30-1 (February 2018) . - p.203-211 Titre : Birth weight interacts with a functional variant of the oxytocin receptor gene (OXTR) to predict executive functioning in children Type de document : texte imprimé Auteurs : Mark WADE, Auteur ; Heather PRIME, Auteur ; Thomas J. HOFFMANN, Auteur ; Louis A. SCHMIDT, Auteur ; Thomas G. O'CONNOR, Auteur ; Jennifer M. JENKINS, Auteur Article en page(s) : p.203-211 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Genetic variation in the oxytocin receptor gene (OXTR) is associated with several psychiatric conditions characterized by deficits in executive functioning (EF). A specific OXTR variant, rs2254298, has previously been associated with brain functioning in regions implicated in EF. Moreover, birth weight variation across the entire range is associated with individual differences in cortical structure and function that underlie EF. This is the first study to examine the main and interactive effect between rs2254298 and birth weight on EF in children. The sample consisted of 310 children from an ongoing longitudinal study. EF was measured at age 4.5 using observational tasks indexing working memory, cognitive flexibility, and inhibitory control. A family-based design that controlled for population admixture, stratification, and nongenomic confounds was employed. A significant genetic association between rs2254298 and EF was observed, with more copies of the major allele (G) associated with higher EF. There was also a significant interaction between rs2254298 and birth weight, such that more copies of the major allele in combination with higher birth weight predicted better EF. Findings suggest that OXTR may be associated with discrete neurocognitive abilities in childhood, and these effects may be modulated by intrauterine conditions related to fetal growth and development.

Cumulative contextual risk, maternal responsivity, and social cognition at 18 months / Mark WADE in Development and Psychopathology, 27-1 (February 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-1 (February 2015) . - p.189-203 Titre : Cumulative contextual risk, maternal responsivity, and social cognition at 18 months Type de document : texte imprimé Auteurs : Mark WADE, Auteur ; Chris MOORE, Auteur ; Janet Wilde ASTINGTON, Auteur ; Kristen FRAMPTON, Auteur ; Jennifer M. JENKINS, Auteur Article en page(s) : p.189-203 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : By 18 months children demonstrate a range of social–cognitive skills that can be considered important precursors to more advanced forms of social understanding such as theory of mind. Although individual differences in social cognition have been linked to neurocognitive maturation, sociocultural models of development suggest that environmental influences operate in the development of children's social–cognitive outcomes. In the current study of 501 children and their mothers, we tested and found support for a model in which distal environmental risk, assessed when children were newborns, was indirectly associated with children's social–cognitive competency at 18 months through mothers' responsivity at 18 months. Part of this effect also operated through children's concomitant language skills, suggesting both a language-mediated and a language-independent mechanism of social–cognitive development. These findings are discussed with respect to the Vygotskian themes of internalization and semiotic mediation.

Environmental determinants of physiological reactivity to stress: The interacting effects of early life deprivation, caregiving quality, and stressful life events / Mark WADE in Development and Psychopathology, 32-5 (December 2020)

Here, we used data from a longitudinal randomized controlled trial of foster care for institutionally reared children to examine whether caregiving quality and stressful life events (SLEs) in early adolescence (age 12) influence patterns of hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) reactivity. Controlling for the effect of institutional care, higher caregiving quality at age 12 was associated with heightened cortisol and SNS reactivity. However, moderation analysis revealed that the latter effect was only observed among never-institutionalized children, whereas ever-institutionalized children demonstrated a persistently blunted SNS response regardless of recent caregiving quality. Among institutionally reared children, SLEs interacted with prior random assignment to foster care, such that those placed in foster care early in development had a SNS response that approximated never-institutionalized children when SLEs at age 12 were low. In contrast, SNS reactivity was persistently blunted among those with prolonged deprivation, regardless of recent SLEs. Early-life deprivation is associated with persistent blunting of stress response systems, but normalization may be achievable if SLEs are limited following placement into enriched family-based care.

Heightened sensitivity to the caregiving environment during adolescence: implications for recovery following early-life adversity / Natalie L. COLICH in Journal of Child Psychology and Psychiatry, 62-8 (August 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-8 (August 2021) Titre : Heightened sensitivity to the caregiving environment during adolescence: implications for recovery following early-life adversity Type de document : texte imprimé Auteurs : Natalie L. COLICH, Auteur ; Margaret A. SHERIDAN, Auteur ; Kathryn L. HUMPHREYS, Auteur ; Mark WADE, Auteur ; Florin TIBU, Auteur ; Charles A. NELSON, Auteur ; Charles H. ZEANAH, Auteur ; Nathan A. FOX, Auteur ; Katie A. MCLAUGHLIN, Auteur Langues : Anglais (eng) Mots-clés : Adolescent  Adverse Childhood Experiences  Child  Child, Institutionalized  Foster Home Care  Humans  Psychopathology  Psychosocial Deprivation  Institutionalization  adolescence  executive function  psychopathology  reward Index. décimale : PER Périodiques Résumé : BACKGROUND: Adolescence has been proposed to be a period of heightened sensitivity to environmental influence. If true, adolescence may present a window of opportunity for recovery for children exposed to early-life adversity. Recent evidence supports adolescent recalibration of stress response systems following early-life adversity. However, it is unknown whether similar recovery occurs in other domains of functioning in adolescence. METHODS: We use data from the Bucharest Early Intervention Project - a randomized controlled trial of foster care for children raised in psychosocially depriving institutions - to examine the associations of the caregiving environment with reward processing, executive functioning, and internalizing and externalizing psychopathology at ages 8, 12, and 16 years, and evaluate whether these associations change across development. RESULTS: Higher quality caregiving in adolescence was associated with greater reward responsivity and lower levels of internalizing and externalizing symptoms, after covarying for the early-life caregiving environment. The associations of caregiving with executive function and internalizing and externalizing symptoms varied by age and were strongest at age 16 relative to ages 8 and 12 years. This heightened sensitivity to caregiving in adolescence was observed in both children with and without exposure to early psychosocial neglect. CONCLUSIONS: Adolescence may be a period of heightened sensitivity to the caregiving environment, at least for some domains of functioning. For children who experience early psychosocial deprivation, this developmental period may be a window of opportunity for recovery of some functions. Albeit correlational, these findings suggest that it may be possible to reverse or remediate some of the lasting effects of early-life adversity with interventions that target caregiving during adolescence.

Pathways to social-emotional functioning in the preschool period: The role of child temperament and maternal anxiety in boys and girls / Hannah F. BEHRENDT in Development and Psychopathology, 32-3 (August 2020)

Research is needed that specifies multiple early risk factors and outcomes simultaneously to demonstrate specificity. Using multigroup longitudinal path analysis in a sample of typically developing children (N = 541), we examined child temperament dimensions (surgency, negative affectivity, and regulation/effortful control) and maternal anxiety in infancy and age 2 as predictors of child externalizing, internalizing, dysregulation, and competence behaviors at age 3. Four primary patterns emerged. First, there was stability in temperament dimensions and maternal anxiety from infancy to age 3. Second, negative affectivity was implicated in internalizing problems and surgency in externalizing problems. Third, effortful control at age 2 was a potent mediator of maternal anxiety in infancy on age 3 outcomes. Fourth, there was suggestive evidence for transactional effects between maternal anxiety and child effortful control. Most pathways operated similarly for boys and girls, with some differences, particularly for surgency. These findings expand our understanding of the roles of specific temperamental domains and postnatal maternal anxiety in a range of social-emotional outcomes in the preschool period, and have implications for efforts to enhance the development of young children's social-emotional functioning and reduce risk for later psychopathology.
