The Trier Social Stress Test (TSST) is a well validated and widely used social stressor that has been shown to induce a 2-4 fold increase in cortisol, the biological output produced by the Hypothalamic-Pituitary-Adrenal (HPA) axis in humans. While studies have explored how modifications to the TSST influence stress responsivity, few studies have created a modified TSST appropriate for vulnerabl...

The present study assessed the modulating effect of education level on cortisol reactivity to the Trier Social Stress Test (TSST) in a sample of 101 middle-aged adults (22 males, 79 females) between the ages of 50 and 65. The TSST involves a public speech and mental arithmetic task in front of an audience. No previous studies have assessed whether education level can have an impact on cortisol ...

Identifying environmental influences on inhibitory control (IC) may help promote positive behavioral and social adjustment. Although chronic stress is known to predict lower IC, the immediate effects of acute stress are unknown. The parasympathetic nervous system (PNS) may be a mechanism of the stress-IC link, given its psychophysiological regulatory role and connections to prefrontal brain reg...

Witnesses to crime often experience stress during the witnessed event. However, most laboratory studies examining eyewitness memory do not include a stressful encoding Participants (N = 129) completed an experimental induction procedure—a modified version of Trier Social Stress Test. We designed three conditions manipulate amount experienced and included types measures assess effectiveness mani...

Impact of body weight loss, body fat distribution and the nutritional status on the cortisol response to the Trier Social Stress Test (TSST) was investigated in this study. Fifty-one men (17 non-obese, 20 abdominally obese and 14 reduced obese) and 28 women (12 non-obese, 10 peripherally obese and 6 reduced obese) were subjected to the TSST in fed and fasted states. The TSST response was determ...

Since the 1990s there have only been a few studies with human subjects that focused on the underlying mechanisms associated with acute psychological stress exposure and even less have been conducted with children. Based on the idea that it is possible to elicit and measure behavioral and physiological patterns in response to stressors in a short period of time, the Trier Social Stress Test (TSS...

The present study aimed at investigating how frequently and intensely depersonalization/derealization symptoms occur during a stressful performance situation in social phobia patients vs. healthy controls, as well as testing hypotheses about the psychological predictors and consequences of such symptoms. N=54 patients with social phobia and N=34 control participants without mental disorders wer...

Social stress affects cognitive processes in general, and memory performance in particular. However, the direction of these effects has not been clearly established, as it depends on several factors. Our aim was to determine the impact of the hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) reactivity to psychosocial stress on short-term non-declarative memory and ...
