Behavioral disinhibition and cortisol reactivity as a function of psychosocial stress and personality in adolescents
… by impulsivity and riskiness tasks) and salivary cortisol reactivity in a sample of 88 adolescents. Results demonstrated that NEM and CON were protective of impulsivity and riskiness, respectively, for adolescents in the no-stress condition. Importantly, low CON adolescents in the no-stress …

Examining Child Sex as a Moderator of the Relationship Between Cortisol Reactivity and Symptoms Over Time
Females’ reactivity to stress appears to be closely tied to internalizing symptoms, while males who are under-reactive may be at risk for externalizing problems. Little is known about when such differences emerge, despite possible implications for early prevention. Cortisol reactivity to a …

Associations Between and Changes in Hippocampal Volume and the Cortisol Response Over Time: The Role of Childhood Maltreatment and Depression
… study was to (1) test the hypothesis that (1) cortisol reactivity and hippocampal volume are correlated mediators of the relation between childhood maltreatment; and (2) examine changes in, and associations between cortisol reactivity and hippocampal volume over time specifically within the …

The impact of stress on the prefrontal cortex: a view of how socioeconomic status impacts executive function
… Alterations within the HPA axis, particularly cortisol levels, are shown to impact brain development especially the prefrontal cortex (PFC) which is a major region supporting executive function. Although the stress regulation mechanism seems valid, the influence of early life stress on the PFC …

Trait Emotional Intelligence: Protecting Health from the Negative Impact of Stress
… designs were used; both objective (salivary cortisol) and subjective (life event inventory) measures of stress were used; personality, gender and age were considered as control variables wherever the predictive power of EI was explored, and health was explored as a multidimensional construct. …

Lifetime stress, blood pressure, heart rate, and salivary cortisol levels in post-menopausal women
… pressure (BP), heart rate (HR), and salivary cortisol excretion in post-menopausal women. The second purpose of this study was to examine the interactions between the hypothalamic-pituitary-adrenal (HPA) axis and the cardiovascular system in these women. Two measures of past stress were …

Exploring the Pathophysiology of Chronic Depression: The Interplay between Depression, Cortisol Responses, and Personality
… the interplay between chronic depression, cortisol responses, and personality. Study 1 examined cortisol responses to the Trier Social Stress Test (TSST) in CMDD participants (n=29) as compared to healthy controls (n=28). It was hypothesized that cortisol responses would be greater in the …

Acute Psychological Stress and Food Intake in Humans: A Scoping Review
… (e.g., epinephrine and norepinephrine) and cortisol release. Stress-induced cortisol secretion has been shown to elicit a decrease, increase, or no change in the homeostatic mechanisms of food intake (e.g., appetite, appetite hormones, food intake). However, homeostatic control can be …

Moderators and underlying mechanisms of stress-induced eating
… accounts of stress-induced eating propose that cortisol secretion during the physiological stress response has an appetitive effect, a theory that has received support from the laboratory, but has not been tested in the field. Six studies are presented in the present thesis, investigating the …
