Stress pulls us apart: Anxiety leads to differences in competitive confidence under stress
Background: Social competition is a fundamental mechanism of evolution yet little is known about factors that affect competitive success, especially in humans. Some key factors might be stress and an individual’s trait anxiety, meaning their susceptibility to [Read more…]

Prenatal tobacco exposure and infant stress reactivity: Role of child sex and maternal behavior.
Background: A study was designed to examine the association between prenatal tobacco exposure (PTE) and infant cortisol reactivity of children 9 months of age. Data was obtained from [Read more…]
Latent trait cortisol (LTC) levels: Reliability, validity, and stability.
Background: The regulation of hypothalamic pituitary adrenal (HPA) axis contributes to individual differences in health and human development. [Read more…]
Salivary Cortisol, Alpha-Amylase & Stress-Induced Telomere Shortening as Biomarkers of Health and Aging
Background: Recent research links life stress to premature telomere shortening and human aging. However, this association has only been demonstrated in Western contexts, where stress is typically lower and life expectancies longer. Using innovative approaches, [Read more…]
Alpha-amylase reactivity in relation to psychopathic traits in adults
Background: In the present study, we examined sAA, in addition to salivary cortisol, in a relatively large sample [Read more…]

Maternal intimate partner violence exposure, child cortisol reactivity and child asthma
Background: Study investigates association between intimate partner violence (IPV) exposure and increased risk of childhood asthma, and assesses whether this relationship differs by child HPA reactivity. Findings support the theory that children who are physiologically reactive are the most vulnerable to adverse health outcomes when faced with environmental stressors.
Maternal Disrupted Communication During Face-to-Face Interaction at 4 months: Relation to Maternal and Infant Cortisol Among at-Risk Families
Background: This study evaluates the association between maternal communication and stress response in infants. Results point to low maternal cortisol as a possible mechanism contributing to the mother’s difficulty in sensitively attuning to her infant’s cues, which in turn has implications for the infant’s reactivity to and recovery from a mild stressor in early infancy.
