Autonomic complexity and emotion (dys-)regulation in early childhood across high- and low-risk contexts / Daniel BERRY in Development and Psychopathology, 31-3 (August 2019)

These processes are supported by the engagement of the autonomic nervous system (ANS), a physiological hub of a vast network tasked with dynamically integrating real-time experiential inputs with internal motivational and goal states. To date, much of what is known about the ANS and emotion regulation has been based on measures of respiratory sinus arrhythmia, a cardiac indicator of parasympathetic activity. In the present study, we draw from dynamical systems models to introduce two nonlinear indices of cardiac complexity (fractality and sample entropy) as potential indicators of these broader ANS dynamics. Using data from a stratified sample of preschoolers living in high- (i.e., emergency homeless shelter) and low-risk contexts (N = 115), we show that, in conjunction with respiratory sinus arrhythmia, these nonlinear indices may help to clarify important differences in the behavioral manifestations of emotion regulation. In particular, our results suggest that cardiac complexity may be especially useful for discerning active, effortful emotion regulation from less effortful regulation and dysregulation.

Differential susceptibility to effects of maternal sensitivity? A study of candidate plasticity genes / Jay BELSKY in Development and Psychopathology, 27-3 (August 2015)

ROISMAN, Auteur Article en page(s) : p.725-746 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Here we tested whether there was genetic moderation of effects of early maternal sensitivity on social-emotional and cognitive-linguistic development from early childhood onward and whether any detected Gene × Environment interaction effects proved consistent with differential-susceptibility or diathesis-stress models of Person × Environment interaction (N = 695). Two new approaches for evaluating models were employed with 12 candidate genes. Whereas maternal sensitivity proved to be a consistent predictor of child functioning across the primary-school years, candidate genes did not show many main effects, nor did they tend to interact with maternal sensitivity/insensitivity. These findings suggest that the developmental benefits of early sensitive mothering and the costs of insensitive mothering look more similar than different across genetically different children in the current sample. Although acknowledgement of this result is important, it is equally important that the generally null Gene × Environment results reported here not be overgeneralized to other samples, other predictors, other outcomes, and other candidate genes.

Gene–environment interaction between dopamine receptor D4 7-repeat polymorphism and early maternal sensitivity predicts inattention trajectories across middle childhood / Daniel BERRY in Development and Psychopathology, 25-2 (May 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-2 (May 2013) . - p.291-306 Titre : Gene–environment interaction between dopamine receptor D4 7-repeat polymorphism and early maternal sensitivity predicts inattention trajectories across middle childhood Type de document : Texte imprimé et/ou numérique Auteurs : Daniel BERRY, Auteur ; Kirby DEATER-DECKARD, Auteur ; Kathleen MCCARTNEY, Auteur ; Zhe WANG, Auteur ; Stephen A. PETRILL, Auteur Article en page(s) : p.291-306 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Evidence suggests that the 7-repeat variant of a 48 base pair variable number tandem repeat polymorphism in the dopamine receptor D4 (DRD4) gene may be associated with the development of attention problems. A parallel literature suggests that genes linked to dopaminergic functioning may be associated with differential sensitivity to context, such that the direction of the genetic effect is hypothesized to vary across environmental experience. Guided by these literatures, we used data from the NICHD Study of Early Child Care and Youth Development to consider (a) whether individual differences in children's inattention problems across middle childhood are predicted by gene–environment interactions between the DRD4 gene 7-repeat polymorphism and children's experiences of maternal sensitivity across infancy and early childhood and (b) the degree to which such interactions are consistent with the differential-sensitivity model. Largely consistent with the hypothesized model, gene–environment interactions indicated that, in the context of insensitive early maternal care, the DRD4 7-repeat polymorphism was associated with higher levels of inattention. Although somewhat less consistently, there was also evidence that, in the context of highly sensitive care, the 7-repeat polymorphism was associated with lower levels of inattention. Overall, the magnitude of the absolute genetic effect increased over time, as children's inattention trajectories diverged.

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.
