Allostasis and allostatic load in the context of poverty in early childhood / Clancy BLAIR in Development and Psychopathology, 23-3 (August 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-3 (August 2011) . - p.845-857 Titre : Allostasis and allostatic load in the context of poverty in early childhood Type de document : Texte imprimé et/ou numérique Auteurs : Clancy BLAIR, Auteur ; C. 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.

Developing a neurobehavioral animal model of poverty: Drawing cross-species connections between environments of scarcity-adversity, parenting quality, and infant outcome / Rosemarie E. PERRY in Development and Psychopathology, 31-2 (May 2019)

Cybele RAVER, Auteur ; Clancy BLAIR, Auteur Article en page(s) : p.399-418 Langues : Anglais (eng) Mots-clés : brain development parenting poverty regulation Index. décimale : PER Périodiques Résumé : Children reared in impoverished environments are at risk for enduring psychological and physical health problems. Mechanisms by which poverty affects development, however, remain unclear. To explore one potential mechanism of poverty's impact on social–emotional and cognitive development, an experimental examination of a rodent model of scarcity-adversity was conducted and compared to results from a longitudinal study of human infants and families followed from birth (N = 1,292) who faced high levels of poverty-related scarcity-adversity. Cross-species results supported the hypothesis that altered caregiving is one pathway by which poverty adversely impacts development. Rodent mothers assigned to the scarcity-adversity condition exhibited decreased sensitive parenting and increased negative parenting relative to mothers assigned to the control condition. Furthermore, scarcity-adversity reared pups exhibited decreased developmental competence as indicated by disrupted nipple attachment, distress vocalization when in physical contact with an anesthetized mother, and reduced preference for maternal odor with corresponding changes in brain activation. Human results indicated that scarcity-adversity was inversely correlated with sensitive parenting and positively correlated with negative parenting, and that parenting fully mediated the association of poverty-related risk with infant indicators of developmental competence. Findings are discussed from the perspective of the usefulness of bidirectional–translational research to inform interventions for at-risk families.

Poverty, household chaos, and interparental aggression predict children's ability to recognize and modulate negative emotions / C. Cybele RAVER in Development and Psychopathology, 27-3 (August 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-3 (August 2015) . - p.695-708 Titre : Poverty, household chaos, and interparental aggression predict children's ability to recognize and modulate negative emotions Type de document : Texte imprimé et/ou numérique Auteurs : C. Cybele RAVER, Auteur ; Clancy BLAIR, Auteur ; Patricia GARRETT-PETERS, Auteur Article en page(s) : p.695-708 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The following prospective longitudinal study considers the ways that protracted exposure to verbal and physical aggression between parents may take a substantial toll on emotional adjustment for 1,025 children followed from 6 to 58 months of age. Exposure to chronic poverty from infancy to early childhood as well as multiple measures of household chaos were also included as predictors of children's ability to recognize and modulate negative emotions in order to disentangle the role of interparental conflict from the socioeconomic forces that sometimes accompany it. Analyses revealed that exposure to greater levels of interparental conflict, more chaos in the household, and a higher number of years in poverty can be empirically distinguished as key contributors to 58-month-olds' ability to recognize and modulate negative emotion. Implications for models of experiential canalization of emotional processes within the context of adversity are discussed.
