Abstract

The goal of the present study was to investigate the role of early social deprivation in shaping the effectiveness of parent support to alleviate hypothalamic-pituitary-adrenal (HPA)-axis-stress responses of children (ages 8.9-11, M = 9.83 years, SD = .55). The sample was equally divided between children who had been adopted internationally from orphanage care by age 5 (n = 40) and an age- and gender-matched group of nonadopted (NA) children (n = 40). On average, internationally adopted children were invited to the laboratory 7.6 years postadoption (SD = 1.45). We experimentally manipulated the provision of parent support during the 5-min speech preparation period before a modified Trier Social Stress Test (TSST) and examined its effect on levels of salivary cortisol secreted in response to this laboratory stressor. All participants were randomly assigned to receive support from their parent or a stranger. Analyses revealed a significant interaction of support condition and group such that parent support significantly dampened the cortisol-stress response in NA children compared with support from a stranger, whereas the cortisol response curves of postinstitutionalized (PI) children did not differ between the parent- and stranger-support conditions. Cortisol reactivity for PI children in both conditions was lower than that of NA children in the stranger-support condition. Social deprivation during the first few years of life may shape neurobehavioral development in ways that reduce selective responses to caregivers versus strangers.

  • Parental support no longer buffers HPA axis reactivity during puberty/adolescence.

    “Interestingly, parental support no longer buffers HPA axis reactivity during this developmental stage (110).”

    From Developmental Trajectories of Early Life Stress and Trauma: A Narrative Review on Neurobiological Aspects Beyond Stress System Dysregulation (2019) · cites this paper as [110]

    The Social Buffering of the HPA Axis section reports that parental presence was no longer effective at buffering HPA reactivity in typically developing adolescents aged 15–16. The Discussion says whether changes during ages 11–13.5 are linked to puberty or chronological age remains under study. The claim therefore extends a finding for 15–16-year-olds to puberty or adolescence more broadly. (LLM, conf=0.87)

  • Stress responsivity in early childhood decreases with age throughout the preschool period, suggesting a potential social buffering of the HPA axis by a nurturing caregiver, who may operate as a safety signal.

    “Some longitudinal studies suggest that stress responsivity in early childhood decreases with age throughout the preschool period (101, 105–107), suggesting a potential social buffering of the HPA axis by a nurturing caregiver, who may operate as a safety signal (108–110).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
