Beyond orchids and dandelions: Susceptibility to environmental influences is not bimodal / Xiaoya ZHANG in Development and Psychopathology, 35-1 (February 2023)
[article]
Titre : Beyond orchids and dandelions: Susceptibility to environmental influences is not bimodal Type de document : Texte imprimé et/ou numérique Auteurs : Xiaoya ZHANG, Auteur ; Keith WIDAMAN, Auteur ; Jay BELSKY, Auteur Article en page(s) : p.191-203 Langues : Anglais (eng) Mots-clés : differential susceptibility domain general versus specific polygenic scores susceptibility continuum temperament Index. décimale : PER Périodiques Résumé : This study focused on generality versus specificity of susceptibility of effects of eight family and child-care exposures measured between 3 and 54 months of age (e.g., sensitive parenting, child-care quality) on five child development outcomes assessed at age 4.5 years (e.g. behavior problems, preacademic skill), using data from The National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (n = 1,364, boys = 705; White = 1,097, Black = 176, other = 91), while applying a novel influence-statistics method. Results indicated that susceptibility across the environment-predictor:child-outcome associations is normally rather than bimodally (i.e., orchid-dandelion) distributed. Analysis of susceptibility documents both domain generality and specificity of developmental plasticity, with effect sizes proving small in the former case. As predicted, children who as infants had difficult temperaments or who scored higher on a polygenic-plasticity score (serotonin-transporter-linked promoter region [5-HTTLPR], dopamine receptor D4 [DRD4], brain-derived neurotrophic factor [BDNF]) proved somewhat more susceptible to some of the environmental effects investigated. Results lead to the recommendation that two-types-of-individuals vis-a-vis susceptibility to environmental influences be questioned and general-trait conceptions of susceptibility be further investigated.
