Stress‐related cortisol responsivity modulates prospective memory

Abstract

It is known that there is inter-individual variation in behavioural and physiological stress reactions to the same stressor. The present study aimed to examine the impact of cortisol responsivity on performance in a complex real life-like prospective memory (PM) paradigm by a re-analysis of data published previously, with a focus on the taxonomy of cognitive dimensions of PM. Twenty-one male subjects were stressed with the Socially Evaluated Cold Pressor Test (SECPT) before the planning of intentions. Another group of 20 males underwent a control procedure. Salivary cortisol was measured to assess the intensity of the biological stress response. Additionally, participants rated the subjective experience of stress on a 5-point rating scale. Stressed participants were post-hoc differentiated in high (n = 11) and low cortisol responders (n = 10). Cortisol niveau differed significantly between the two groups, whereas subjective stress ratings did not. PM performance of low cortisol responders was stable across time and the PM performance of controls declined. High cortisol responders showed a nominally weaker PM retrieval across the early trails and significantly improved only on the last trial. The data demonstrate for the first time that participants with a low cortisol responsivity may benefit from stress exposure before the planning phase of PM. PM performance of high cortisol responders shows a more inconsistent pattern, which may be interpreted in the sense of a recency effect in PM retrieval. Alternatively, high cortisol responses may have a deteriorating effect on PM retrieval, which disappeared on the last trials of the task as a result of the decrease of cortisol levels across time. Importantly, the data also demonstrate that the intensity of cortisol responses does not necessarily correspond to the intensity of the mental experience of stress.

Dietary Supplementation with Enterococcus faecium R1 Attenuates Intestinal and Liver Injury in Piglets Challenged by Lipopolysaccharide

“…The results of this study showed that dietary supplementation with E. faecium R1 promoted the secretion of glucagon when piglets were challenged with LPS. Previous studies have shown that cortisol (COR) is a hormone produced in response to stress [ 47 ]. After the LPS challenge, the contents of COR in the blood of piglets fed with or without dietary supplementation of E. faecium R1 were increased, which showed that E. faecium R1 cannot inhibit the stress response.…”

Cortisol, cytokines, and autonomic changes during a cognitive load in patients with chronic cerebral ischemia

“…Это может быть связано как с активацией симпатоадреналовой системы, включающейся на первой стадии стресса, так и с возрастанием уровня кортизола при развитии адаптационного синдрома. В соответствии с классическими представлениями кортизол участвует в регуляции артериального давления, тормозит процессы воспаления, а также вовлечен в регуляцию механизмов памяти [4]. Во многих работах показано, иммуносупрессивное влияние кортизола на иммунную систему, вместе с тем более детальное исследование влияния кортизола выявило, что кортизол может обладать и иммуномодулирующим действием [5,6].…”

Wellbeing of Military Personnelas Reflected in Sleep Quality

“…The accumulation of urea does not change during short-term exercise, but it increases with longer-lasting effort and depends primarily on the duration and intensity of exercise (Mougios, 2019). Cortisol is known to be a key factor in the biological stress response, and it mainly contributes to the regulation of stress responses (Glienke & Piefke, 2017). An increased release of cortisol occurs in a body facing a stressor by up to ten times the normal amount (Lüllmann, Mohr, & Wehling, 2004).…”
