Individual responses to psychosocial stress are influenced by a neural mechanism
January 13, 2017Prefrontal Cortex Activity Is Associated with Biobehavioral Components of the Stress Response Author: Wheelock MD, et al (2016), Frontiers in Human Neuroscience. Contemporary theory suggests that prefrontal cortex (PFC) function is associated with individual variability in the psychobiology of the stress response. Advancing our understanding of this complex biobehavioral pathway has potential to provide insight […]

A contribution to a special issue on Hormones and Human Competition. Since Archer’s (2006) influential meta-analysis, there has been a major increase in the number of studies investigating the effect of competition outcome on […]
The stress response to perceived discrimination as indicated by salivary measures
December 6, 2016Perceived Discrimination, Racial Identity, and Multisystem Stress Response to Social Evaluative Threat among African American Men and Women Author: Lucas T, et al (2016), Psychosomatic Medicine. OBJECTIVES: Understanding individual differences in the psychobiology of the stress response is critical to grasping how psychosocial factors contribute to racial and ethnic health disparities. However, the ways in […]
Chronic caregiver-related stress linked to diurnal salivary alpha-amylase rhythms
November 29, 2016Diurnal Salivary Alpha-Amylase Dynamics Among Dementia Family Caregivers Author: Liu Y, et al (2016), Health Psychology. Objective: The study examined diurnal regulation of salivary alpha-amylase (sAA) in association with daily stressors, adult day services (ADS) use, and other caregiving characteristics. Method: A sample of 165 family caregivers of individuals with dementia (IWD) completed an 8-day […]
Determining the appropriate statistical approach for effective analysis of hormone ratios
November 21, 2016How to use and interpret hormone ratios Author: Sollberger S, et al (2016), Psychoneuroendocrinology. Hormone ratios have become increasingly popular throughout the neuroendocrine literature since they offer a straightforward way to simultaneously analyze the effects of two interdependent hormones. However, the analysis of ratios is associated with statistical and interpretational concerns which have not been […]

Salivary uric acid modulates stress-related hippocampal activity
November 3, 2016The hippocampal response to psychosocial stress varies with salivary uric acid level Author: Goodman AM, et al (2016), Neuroscience. Uric acid is a naturally occurring, endogenous compound that impacts mental health. In particular, uric acid levels are associated with emotion-related psychopathology (e.g., anxiety and depression). Therefore, understanding uric acid’s impact on the brain would provide […]
Study demonstrates combined effects of salivary cortisol & DHEA-S in predicting depressive symptoms
October 24, 2016Concurrent and prospective associations between HPA axis activity and depression symptoms in newlywed women Author: Ge F, et al (2016), Psychoneuroendocrinology. We investigated the extent to which individual differences in activity of the hypothalamic pituitary adrenal axis (HPA) are associated with depressive symptoms among newlywed couples. Participants were 218 couples (M age 28.4 years; 94% […]
