Cybele RAVER, Auteur ; Douglas A. GRANGER, Auteur ; W. Roger MILLS-KOONCE, Auteur ; Leah C. HIBEL, Auteur ; THE FAMILY LIFE PROJECT KEY INVESTIGATORS, Auteur Année de publication : 2011 Article en page(s) : p.845-857 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This paper examined the relation of early environmental adversity associated with poverty to child resting or basal level of cortisol in a prospective longitudinal sample of 1135 children seen at 7, 15, 24, 35, and 48 months of age. We found main effects for poor housing quality, African American ethnicity, and low positive caregiving behavior in which each was uniquely associated with an overall higher level of cortisol from age 7 to 48 months. We also found that two aspects of the early environment in the context of poverty, adult exits from the home and perceived economic insufficiency, were related to salivary cortisol in a time-dependent manner. The effect for the first of these, exits from the home, was consistent with the principle of allostatic load in which the effects of adversity on stress physiology accumulate over time. The effect for perceived economic insufficiency was one in which insufficiency was associated with higher levels of cortisol in infancy but with a typical but steeper decline in cortisol with age at subsequent time points.

Bidirectional genetic and environmental influences on mother and child behavior: The family system as the unit of analyses / W. Roger MILLS-KOONCE in Development and Psychopathology, 19-4 (Fall 2007)

Roger MILLS-KOONCE, Auteur ; Martha J. COX, Auteur ; Cathi B. PROPPER, Auteur ; Jean-Louis GARIEPY, Auteur ; Clancy BLAIR, Auteur ; Patricia GARRETT-PETERS, Auteur Année de publication : 2007 Article en page(s) : p.1073-1087 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Family systems theory proposes that an individual's functioning depends on interactive processes within the self and within the context of dyadic family subsystems. Previous research on these processes has focused largely on behavioral, cognitive, and psychophysiological properties of the individual and the dyad. The goals of this study were to explore genetic and environmental interactions within the family system by examining how the dopamine receptor D2 gene (DRD2) A1+ polymorphism in mothers and children relates to maternal sensitivity, how maternal and child characteristics might mediate those effects, and whether maternal sensitivity moderates the association between DRD2 A1+ and child affective problems. Evidence is found for an evocative effect of child polymorphism on parenting behavior, and for a moderating effect of child polymorphism on the association between maternal sensitivity and later child affective problems. Findings are discussed from a family systems perspective, highlighting the role of the family as a context for gene expression in both mothers and children.

Evocative gene–parenting correlations and academic performance at first grade: An exploratory study / Cathi B. PROPPER in Development and Psychopathology, 24-4 (November 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-4 (November 2012) . - p.1265-1282 Titre : Evocative gene–parenting correlations and academic performance at first grade: An exploratory study Type de document : Texte imprimé et/ou numérique Auteurs : Cathi B. PROPPER, Auteur ; Michael J. SHANAHAN, Auteur ; Rosemary RUSSO, Auteur ; W. Roger MILLS-KOONCE, Auteur Année de publication : 2012 Article en page(s) : p.1265-1282 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Academic performance during the first years of school lays the groundwork for subsequent trajectories of academic success throughout childhood and adolescence. The current study tests a model according to which a gene–parenting correlation in the first 3 years of life is associated with subsequent psychosocial adjustment and then academic performance in the first grade (as indicated by teachers' assessment of academic behavior and two subscales of the Woodcock–Johnson Test of Achievement, Third Edition). Drawing on multiple waves of data from the Durham Child Health and Development Study, we find that risk alleles for dopamine receptor genes (dopamine receptor D4 for girls, dopamine receptor D2 for boys) are associated with less sensitive parenting. For girls, parenting mediates the link between dopamine receptor D4 and all academic outcomes. There is some indication that parenting also influences girls' withdrawn behavior in the classroom, which in turn influences teachers' assessments of academic performance. For boys, some evidence suggests that parenting is associated with emotion regulation, which is associated with teachers' assessments of academic behavior and both subscales of the Woodcock–Johnson. Replications of this exploratory study are necessary, but these findings provide a first step in understanding how evocative correlations in the home may predict indicators of psychosocial adjustment that in turn influence performance and achievement at school.

Maternal sensitivity and adrenocortical functioning across infancy and toddlerhood: Physiological adaptation to context? / Daniel BERRY in Development and Psychopathology, 29-1 (February 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-1 (February 2017) . - p.303-317 Titre : Maternal sensitivity and adrenocortical functioning across infancy and toddlerhood: Physiological adaptation to context? Type de document : Texte imprimé et/ou numérique Auteurs : Daniel BERRY, Auteur ; Clancy BLAIR, Auteur ; Michael T. WILLOUGHBY, Auteur ; Douglas A. GRANGER, Auteur ; W. Roger MILLS-KOONCE, Auteur Article en page(s) : p.303-317 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : AbstractTheory suggests that early experiences may calibrate the “threshold activity” of the hypothalamus–pituitary–adrenal axis in childhood. Particularly challenging or particularly supportive environments are posited to manifest in heightened physiological sensitivity to context. Using longitudinal data from the Family Life Project (N = 1,292), we tested whether links between maternal sensitivity and hypothalamus–pituitary–adrenal axis activity aligned with these predictions. Specifically, we tested whether the magnitude of the within-person relation between maternal sensitivity and children's cortisol levels, a proxy for physiological sensitivity to context, was especially pronounced for children who typically experienced particularly low or high levels of maternal sensitivity over time. Our results were consistent with these hypotheses. Between children, lower levels of mean maternal sensitivity (7–24 months) were associated with higher mean cortisol levels across this period (measured as a basal sample collected at each visit). However, the magnitude and direction of the within-person relation was contingent on children's average levels of maternal sensitivity over time. Increases in maternal sensitivity were associated with contemporaneous cortisol decreases for children with typically low-sensitive mothers, whereas sensitivity increases were associated with cortisol increases for children with typically high-sensitive mothers. No within-child effects were evident at moderate levels of maternal sensitivity.

While environmental factors and physiological processes are associated with its etiology, few studies have examined how these factors jointly predict inhibitory control. This study examined whether respiratory sinus arrhythmia (RSA) functioned as a mediator or moderator of both cumulative sociodemographic risk and parenting behaviors on inhibitory control during early childhood. Methods The sample included 206 children and their biological mothers. At 24, 30, and 36 months of child age dyads participated in a series of laboratory visits in which sociodemographic, parenting, and baseline RSA (RSAB) data were collected. Inhibitory control was assessed at 36 months using a gift-wrap delay task. Results A series of structural equation models yielded no evidence that RSAB mediated the relations of risk or parenting and inhibitory control. RSAB moderated the effects of risk, such that high-risk children with low RSAB performed more poorly on tasks of inhibitory control, while high-risk children with high RSAB did not. Conclusions These results suggest that higher levels of RSAB may mitigate the influence of environmental risk on the development of inhibitory control early childhood.
