Findings regarding associations between maternal sensitivity and infant and mother adrenocortical function have been inconsistent. Nor have studies addressed the issue of intra-individual, between-challenge cortisol variability in the context of maternal sensitivity. In this study, we combine several design features aimed at sensitizing analyses to these issues. Cortisol secretion of 297 infant...

UNLABELLED Although maternal sensitivity has been shown to influence social-emotional development, the role of verbal stimulation on infant developmental outcomes has received less exploration. Recent research has focused on intentional behaviors within the context of a mother-infant interaction as a critical influence and as distinct from sensitivity. In this investigation 6377 mother-infant d...

It has been suggested that biological factors confer increased sensitivity to environmental influences on depressive symptoms during adolescence, a crucial time for the onset of depressive disorders. Given the critical role of the hippocampus in sensitivity to stress and processing of contextual aspects of the environment, investigation of its role in determining sensitivity to environmental co...

Family systems theory proposes that an individual's functioning depends on interactive processes within the self and within the context of dyadic family subsystems. Previous research on these processes has focused largely on behavioral, cognitive, and psychophysiological properties of the individual and the dyad. The goals of this study were to explore genetic and environmental interactions wit...

BACKGROUND Very preterm (VPT) infants are hospitalized in Neonatal Intensive Care Units (NICUs) and are exposed to life-saving procedures eliciting pain-related stress. Recent research documented that pain-related stress might result in birth-to-discharge increased methylation of serotonin transporter gene (SLC6A4) in VPT infants, leading to poorer stress regulation at 3 months of age in VPT in...

OBJECTIVE Maternal maltreatment history and current parenting stress are associated with parenting difficulties. However, researchers have not investigated the mechanism by which these variables are interlinked. We hypothesized that parenting stress mediates the relation between history of maltreatment and parenting behavior. METHODS We assessed a community sample of 291 mothers as they inter...

KEY POINTS In the Western world, obesogenic diets containing high fat and high sugar (HFHS) are commonly consumed during pregnancy, although their effects on the metabolism of the mother, in relation to feto-placental glucose utilization and growth, are unknown. In the present study, the consumption of an obesogenic HFHS diet compromised maternal glucose tolerance and insulin sensitivity in lat...

The extent to which engaged maternal coping styles moderate the association between toddler's temperamental reactivity and mothers' sensitivity to children's negative emotions was examined in 89 mother-child dyads. Primiparous mothers completed a measure of coping styles prenatally. When toddlers were 16 months old, mothers completed a measure of perceived toddler temperament and a self-report ...
