BACKGROUND Non-syndromic clefts of the orofacial region occur in approximately 1 per 500 to 2,500 live births, depending on geographical area and ethnicity. It can be supposed that the disruption of the normal facial structure and the long-standing pressure of treatment from birth to adulthood bring about a range of life stressors which may lead to a long-lasting impact on affected subjects thr...

Reports of exaggerated anxiety and physiological hyperreactivity to social-evaluative situations are characteristic of childhood social phobia (SP). However, laboratory research on subjective, autonomic and endocrine functioning in childhood SP is scarce, inconsistent and limited by small sample sizes, limited breadth of measurements, and the use of non-standardized stressor tasks. We exposed 8...

Animal studies suggest a relationship between blunted HPA-axis stress reactivity and increased stress-induced food intake in chronically stressed animals. Such a relationship can potentially explain the underlying mechanisms of emotional eating in humans. However, no studies have experimentally tested the relationship between stress-induced cortisol responses and acute food intake in high and l...

The Trier Social Stress Test (TSST) is an effective psychosocial laboratory protocol for inducing stress in humans and has been used in numerous research studies. The stressor leads to a physiological response of the hypothalamus-pituitary-adrenal axis (HPAA) and the autonomous nervous system (ANS). Common biomarkers are cortisol levels and heart rate. In addition to the physiological stress re...

Inadequate sleep and psychological stress can both elevate physiological stress markers, such as cortisol. Prior studies that have applied induced psychosocial stress after a night of experimental sleep deprivation have found these effects to be compounded. We examined whether the relationship between stress reactivity and poor sleep also extends to habitual sleep patterns. Fifty-nine adult mal...

In contrast to the substantial number of studies investigating the effects of stress on declarative memory, effects of stress on working memory have received less attention. We compared working memory (numerical n-back task with single digits) in 40 men exposed either to psychosocial stress (Trier Social Stress Test (TSST)) or a control condition. Task difficulty was varied using two conditions...

Cognitive reappraisal (CR) is regarded as an effective emotion regulation strategy. Acute stress, however, is believed to impair the functioning of prefrontal-based neural systems, which could result in lessened effectiveness of CR under stress. This study tested the behavioral and neurobiological impact of acute stress on CR. While undergoing fMRI, adult participants ( n = 54) passively viewed...

Psychosocial stress is a potent activator of the hypothalamus-pituitary-adrenal (HPA) axis. While the physiological mechanisms of HPA axis responses to stress as well as its short and long-term consequences have been extensively examined, less is known why someone elicits an acute neuroendocrine stress response, i.e. what are the psychological processes involved and how are they related to the ...

In everyday life, decisions are often made under stress and while being occupied with multiple tasks. It has recently been shown that acute stress impairs decision making under risk. Performing a parallel executive task also caused riskier decision making. To investigate the effects of a combination of these two factors on decision making, we conducted a large (N = 126) experimental study with ...

BACKGROUND Prenatal stress seems to have long-lasting effects on biological and psychological processes of the offspring. However, to date, there have been no studies investigating the effects of prenatal glucocorticoid exposure on psychological, endocrine, and autonomic responses to a standardized psychosocial stress test in children. METHODS A sample of 115 healthy, 10-year-old children was...
