Boys' serotonin transporter genotype affects maternal behavior through self-control: A case of evocative gene–environment correlation / Roni PENER-TESSLER in Development and Psychopathology, 25-1 (February 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-1 (February 2013) . - p.151-162 Titre : Boys' serotonin transporter genotype affects maternal behavior through self-control: A case of evocative gene–environment correlation Type de document : Texte imprimé et/ou numérique Auteurs : Roni PENER-TESSLER, Auteur ; Reut AVINUN, Auteur ; Florina UZEFOVSKY, Auteur ; Shany EDELMAN, Auteur ; Richard P. EBSTEIN, Auteur ; Ariel KNAFO, Auteur Article en page(s) : p.151-162 Index. décimale : PER Périodiques Résumé : Self-control, involving processes such as delaying gratification, concentrating, planning, following instructions, and adapting emotions and behavior to situational requirements and social norms, may have a profound impact on children's adjustment. The importance of self-control suggests that parents are likely to modify their parenting based on children's ability for self-control. We study the effect of children's self-control, a trait partially molded by genetics, on their mothers' parenting, a process of evocative gene–environment correlation. Israeli 3.5-year-old twins (N = 320) participated in a lab session in which their mothers' parenting was observed. DNA was available from most children (N = 228). Mothers described children's self-control in a questionnaire. Boys were lower in self-control and received less positive parenting from their mothers, in comparison with girls. For boys, and not for girls, the serotonin transporter linked polymorphic region gene predicted mothers' levels of positive parenting, an effect mediated by boys' self-control. The implications of this evocative gene–environment correlation and the observed sex differences are discussed.

Early concern and disregard for others as predictors of antisocial behavior / Soo Hyun RHEE in Journal of Child Psychology and Psychiatry, 54-2 (February 2013)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 54-2 (February 2013) . - p.157-166 Titre : Early concern and disregard for others as predictors of antisocial behavior Type de document : Texte imprimé et/ou numérique Auteurs : Soo Hyun RHEE, Auteur ; Naomi P.

VAN HULLE, Auteur ; Irwin D. WALDMAN, Auteur ; Susan E. YOUNG, Auteur ; Carolyn ZAHN-WAXLER, Auteur Année de publication : 2013 Article en page(s) : p.157-166 Langues : Anglais (eng) Mots-clés : Antisocial behavior  empathy  concern for others  disregard for others Index. décimale : PER Périodiques Résumé : Background: Prediction of antisocial behavior is important, given its adverse impact on both the individuals engaging in antisocial behavior and society. Additional research identifying early predictors of future antisocial behavior, or antisocial propensity, is needed. The present study tested the hypothesis that both concern for others and active disregard for others in distress in toddlers and young children predict antisocial behavior during middle childhood and adolescence. Methods: A representative sample of same-sex twins (N = 956) recruited in Colorado was examined. Mother-rated and researcher-observed concern and disregard for others assessed at age 14–36 months were examined as predictors of parent- (age 4–12), teacher- (age 7–12), and self-reported (age 17) antisocial behavior. Results: Observed disregard for others predicted antisocial behavior assessed by three different informants (parents, teachers, and self), including antisocial behavior assessed 14 years later. It also predicted a higher order antisocial behavior factor (? = .58, p .01) after controlling for observed concern for others. Mother-rated disregard for others predicted parent-reported antisocial behavior. Contrary to predictions, neither mother-rated nor observed concern for others inversely predicted antisocial behavior. Results of twin analyses suggested that the covariation between observed disregard for others and antisocial behavior was due to shared environmental influences. Conclusions: Disregard for others in toddlerhood/early childhood is a strong predictor of antisocial behavior in middle childhood and adolescence. The results suggest the potential need for early assessment of disregard for others and the development of potential interventions.

Gene–environment correlation in developmental psychopathology / Ariel KNAFO in Development and Psychopathology, 25-1 (February 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-1 (February 2013) . - p.1-6 Titre : Gene–environment correlation in developmental psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : Ariel KNAFO, Auteur ; Sara R. JAFFEE, Auteur Article en page(s) : p.1-6 Index. décimale : PER Périodiques Résumé : Modern research acknowledges that psychopathology and individual differences in normal development are the joint products of both biological and social influences. Although there have been numerous publications on Gene × Environment interactions in the past decade, gene–environment correlation is another important form of gene–environment interplay that has received less attention. This Special Section demonstrates, using a range of methodological approaches, the importance of gene–environment correlation in developmental psychopathology. Several types of gene–environment correlation are described, including passive, evocative, and active. Other studies highlight the potential for gene–environment correlation to obscure associations between risk exposures and child psychopathology. Future directions for gene–environment correlation research are discussed.

Heritability of children's prosocial behavior and differential susceptibility to parenting by variation in the dopamine receptor D4 gene / Ariel KNAFO in Development and Psychopathology, 23-1 (January 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-1 (January 2011) . - p.53-67 Titre : Heritability of children's prosocial behavior and differential susceptibility to parenting by variation in the dopamine receptor D4 gene Type de document : Texte imprimé et/ou numérique Auteurs : Ariel KNAFO, Auteur ; Salomon ISRAEL, Auteur ; Richard P. EBSTEIN, Auteur Année de publication : 2011 Article en page(s) : p.53-67 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Theoretical considerations and new empirical evidence suggest that children's development cannot simply be explained by either genes or environment but that their interaction is important to understanding child behavior. In particular, a genetic polymorphism, the exon III repeat region of the dopamine receptor D4, has been the focus of interest regarding differential susceptibility to parental influence. To study environmental and genetic influences on children's prosocial behavior, 168 twin pairs (mean age = 44 months) participated in an experiment that assessed prosocial behavior via three measures: compliant prosocial behavior elicited in response to social requests, self-initiated prosocial behavior enacted voluntarily, and mothers' rating of children's behavior. Genetic effects accounted for 34% to 53% of the variance in prosocial behavior. The rest of the variance was accounted for by nonshared environment and error. Parenting measures of maternal positivity, negativity, and unexplained punishment did not correlate significantly with children's prosocial behavior. However, when parenting was stratified by presence or absence of the child's dopamine receptor D4 7-repeat allele in an overlapping sample of 167 children to model differential susceptibility to parental influence, a richer picture emerged. Positive parenting related meaningfully to mother-rated prosocial behavior, and unexplained punishment related positively to self-initiated prosocial behavior, but only among children carrying the 7-repeat allele. The findings demonstrate that a molecular genetic strategy, based on genotyping of common polymorphisms and combined with a classic twin approach, provides a richer description of how genes and environment interact to shape children's behavior, and allows for the identification of differential sensitivity to parental influence.
