Immune and neuroendocrine correlates of temperament in infancy / Thomas G. O'CONNOR in Development and Psychopathology, 29-5 (December 2017)
[article]
Titre : Immune and neuroendocrine correlates of temperament in infancy Type de document : Texte imprimé et/ou numérique Auteurs : Thomas G. O'CONNOR, Auteur ; Kristin SCHEIBLE, Auteur ; Ana Vallejo SEFAIR, Auteur ; Michelle GILCHRIST, Auteur ; Emma Robertson BLACKMORE, Auteur ; Marcia A. WINTER, Auteur ; Megan R. GUNNAR, Auteur ; Claire WYMAN, Auteur ; Jennifer CARNAHAN, Auteur ; Jan A. MOYNIHAN, Auteur ; Mary T. CASERTA, Auteur Article en page(s) : p.1589-1600 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : There is now a clear focus on incorporating, and integrating, multiple levels of analysis in developmental science. The current study adds to research in this area by including markers of the immune and neuroendocrine systems in a longitudinal study of temperament in infants. Observational and parent-reported ratings of infant temperament, serum markers of the innate immune system, and cortisol reactivity from repeated salivary collections were examined in a sample of 123 infants who were assessed at 6 months and again when they were, on average, 17 months old. Blood from venipuncture was collected for analyses of nine select innate immune cytokines; salivary cortisol collected prior to and 15 min and 30 min following a physical exam including blood draw was used as an index of neuroendocrine functioning. Analyses indicated fairly minimal significant associations between biological markers and temperament at 6 months. However, by 17 months of age, we found reliable and nonoverlapping associations between observed fearful temperament and biological markers of the immune and neuroendocrine systems. The findings provide some of the earliest evidence of robust biological correlates of fear behavior with the immune system, and identify possible immune and neuroendocrine mechanisms for understanding the origins of behavioral development.

Titre : Increased freezing and decreased positive affect in postinstitutionalized children Type de document : Texte imprimé et/ou numérique Auteurs : Sarah A. STELLERN, Auteur ; Elisa ESPOSITO, Auteur ; Shanna MLINER, Auteur ; Katherine PEARS, Auteur ; Megan R. GUNNAR, Auteur Article en page(s) : p.88-95 Langues : Anglais (eng) Mots-clés : Deprivation neglect fear positive affect international adoption institutional care Index. décimale : PER Périodiques Résumé : Background Early neglect is associated with increased risk of internalizing disorders in humans and with increased fear behavior in animals. When children are adopted out of orphanages in which they experienced institutional neglect, anxiety and depressive disorders often are not seen until adolescence. What has not been examined is whether even young children adopted from institutional care exhibit heightened fear or behavioral inhibition. Method Children adopted between 15 and 35 months from institutional care were examined twice during their first year postadoption and compared with children of the same age reared in their birth families. A modified version of the Laboratory Temperament Assessment Battery for Preschoolers was used with the children being exposed to two mechanical toys designed to be highly arousing and fear eliciting. Because children in institutions tend to exhibit low levels of positive affect, the children were also examined during exposure to two positive stimuli. Sessions were videotaped and coded by observers blind to the study purpose. Results Postinstitutionalized children froze more in fear vignettes and were less positive in both fear and positive vignettes than nonadopted children. Group differences did notdiminish significantly from the first session to the next, 6 months later. Conclusions Children exposed to early institutional neglect exhibit emotional biases that are consistent with their previously demonstrated risk for the development of internalizing disorders.

Titre : Postadoption parenting and socioemotional development in postinstitutionalized children Type de document : Texte imprimé et/ou numérique Auteurs : Melissa C. GARVIN, Auteur ; Amanda R. TARULLO, Auteur ; Mark J. VAN RYZIN, Auteur ; Megan R. GUNNAR, Auteur Année de publication : 2012 Article en page(s) : p.35-48 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Children adopted from institutions (e.g., orphanages) overseas are at increased risk of disturbances in social relationships and social understanding. Not all postinstitutionalized children exhibit these problems, although factors like the severity of deprivation and duration of deprivation increase their risk. To date, few studies have examined whether postadoption parenting might moderate the impact of early adverse care. Three groups were studied: postinstitutionalized and foster care children both adopted internationally and nonadopted children reared in their families of origin. The Emotional Availability (EA) Scales were assessed at 18 months in parent–child dyads. Parent emotional availability was found to predict two aspects of social functioning shown in previous studies to be impaired in postinstitutionalized children. Specifically, EA positively correlated with emotion understanding at 36 months; in interaction with initiation of joint attention at 18 months and group, it predicted indiscriminate friendliness as scored from a parent attachment interview at 30 months. Among the postinstitutionalized children but not among the children in other groups, higher EA scores reduced the negative association between initiation of joint attention and indiscriminate friendliness, thus suggesting that parenting quality may moderate the effects of early institutional deprivation.
