AbstractIndividuals with a history of low maternal care (MC) frequently present a blunted, yet sometimes also show an increased cortisol stress response. Fasted individuals with low blood glucose levels who are exposed to acute stress typically show an attenuated response pattern in this endocrine marker. Despite well-documented metabolic dysregulations after low MC, a possible interaction of both factors has not been investigated yet. Here, we examined the effects of MC and blood glucose concentration on various aspects of the stress response. Fasted women (N = 122, meanage = 22.12, sdage = 2.56) who experienced either very high, high, or low MC (based on the Parental Bonding Instrument) were randomly assigned to consume grape juice (condition sugar), or water (condition water) prior to being exposed to the Trier-Social-Stress-Test for groups. Salivary cortisol and alpha amylase, blood glucose, and mood ratings were assessed repeatedly. Using multilevel mixed models, we replicated the boosting effect of glucose on the cortisol stress response. While we found neither an effect of MC, nor an interaction between MC and blood glucose availability on the cortisol stress response, we observed an effect of MC on the amylase stress response. We discuss the results in the light of links between various stress/energy systems that possibly mediate health-related MC effects.

Both, early life adversity (ELA), like being exposed to physical or emotional abuse, or low maternal care, and blood glucose availability have been associated with regulatory alterations in the endocrine stress system: here, individuals with a history of ELA and fasting individuals with low blood glucose levels have been shown to exhibit a blunted cortisol response to acute stress. However, a possible interaction of both factors has not been investigated yet, despite well-documented metabolic dysregulations after ELA. Therefore, the current study examined the effects of maternal care and blood glucose concentration on the physiological stress response. After screening for eligibility, N=122 women (meanage=22.12, sdage=2.56) were assigned to either a low, medium or high ELA group based on the maternal care subscale of the Parental Bonding Instrument. After an overnight fast, participants of each group came to the laboratory in the morning and were randomly assigned to either consume grape juice (condition sugar), or water (condition water) prior to being exposed to the Trier Social Stress Test for groups. Salivary samples for cortisol and alpha amylase detection, blood glucose concentrations, and mood ratings were assessed repeatedly. The effects of maternal care and sugar load on cortisol, alpha amylase and blood glucose trajectories were examined using multilevel mixed models. While we could replicate previous results showing the effect of glucose levels on the cortisol stress response, we could neither observe a main effect of ELA on the cortisol stress response, nor an interaction. We did however find an effect of ELA on the amylase stress response. Results are discussed in the light of methodological challenges associated with this type of research, and the possible role of the interaction among the various stress / energy systems in the mediation of ELA effects.

AbstractChronic stress is associated with impacting eating behavior, namely food choice and energy intake, with a shift towards more palatable and energy dense foods. Additionally, eating behavior is influenced by other psychological factors like mood and emotions. The categorization of people into eating types such as restrained, emotional, and external eaters has gained attraction. Reported changes in eating behavior due to psychological stress are only occasionally accompanied by measures of physiological hunger through ghrelin. The primary objective of this study was to investigate how chronic stress and acute cortisol reactivity affect active ghrelin secretion and how these outcomes account for different eating types. 16 healthy, young males (age: 23 ± 3 years, BMI: 22.5 ± 1.3kg/m2) with low (n = 8) and average-to-high (n = 8) chronic stress level were subjected to the Trier Social Stress Test (TSST) and a control version on two separate days. Active ghrelin, cortisol, glucose, and heart rate were measured throughout the test. Subjects rated their hunger by means of visual analog scale and current mood was assessed with the Positive and Negative Affect Scale (PANAS). In addition, participants filled out the Dutch Eating Behavior Questionnaire (DEBQ) to account for their subjective eating behavior. Overall ghrelin values where higher on the test day compared to the control day. Ghrelin values were also higher during the time leading up to the stress or control test (TSST) than during the conclusion of said tests. On both days, mean values for active ghrelin where higher in individuals with low chronic stress exposure compare to those with average-to-high chronic stress exposure. While values from test to control day decreased for lower stressed participants, they slightly increased for higher stressed participants. Cortisol responders displayed higher ghrelin values on test day than cortisol non-responders, but this association inverted for the control day. Results indicate that chronic stress influences acute stress response and further alters active ghrelin production, which in turn can influence eating behavior. Replication in a greater group of participants of differing weight and sex could yield a greater understanding of stress induced eating. Factors such as relaxation techniques and coping mechanisms could further improve our knowledge and evaluate treatment possibilities.

Abstract The present study investigated the effect of acute stress on attentional bias to threat using behavioral and ERP methods. Sixty-two male participants were randomly assigned to a stress condition (Trier Social Stress Test) or a control condition. To examine the impact of stress-induced cortisol on attentional bias to threat, participants in the stress group were split into Low- and High cortisol responders. All participants were then administered a modified dot probe task in which the cues were neutral and angry faces. Behavioral results showed a pattern of attentional bias toward threat in the Control group but not in the stress group. For the ERPs, the P100 peaked earlier for the angry-cued targets than the neutral-cued targets in the Control group, which suggests a rapid, adaptive response toward threat. However, this effect was not observed in the stress group, suggesting a suppressed attentional bias under stress. In addition, the stress group (including both Low and High cortisol responders) showed reduced P300 amplitude to target onset than the Control group. These results suggest that acute stress disrupts attentional bias to threat including a reduction in early bias to threat in addition to a subsequent change of attention allocation.

There is evidence that stress and craving contribute to the development, maintenance, and relapse in cocaine use disorder. Previous research has shown altered physiological responses to psychosocial stress as well as increased vegetative responding to substance-related cues in chronic cocaine users (CU). However, how psychosocial stress and cue-induced craving interact in relation to the physiological response of CU is largely unknown. Therefore, we investigated the interaction between acute psychosocial stress and cocaine-cue-related reactivity in 47 CU and 38 controls. Participants were randomly exposed first to a video-based cocaine-cue paradigm and second to the Trier Social Stress Test (TSST) or vice versa in a crossed and balanced design to investigate possible mutually augmenting effects of both stressors on the physiological stress response. Plasma cortisol, ACTH, and noradrenaline as well as subjective stress and craving were assessed repeatedly over the course of the experimental procedure. Growth models and discontinuous growth models were used to estimate the responses during the cocaine-cue paradigm and TSST. Overall, both groups did not differ in their endocrinological responses to the TSST but CU displayed lower ACTH levels at baseline. The TSST did not elevate craving in CU. However, if the cocaine-cue video was shown first, CU displayed an enhanced cortisol response to the subsequent TSST. Cocaine-cues robustly evoked craving in CU but no stress response, while cue-induced craving was intensified after the TSST. Taken together, CU did not show an altered acute stress response during the TSST but stress and craving together seem to have mutually augmenting effects on their stress response.

Music Listening

Chronic exposure to stress at any age is associated with a myriad of negative physiological and psychological consequences, and as such, development of effective low-cost and non-invasive stress reduction interventions are important. Music listening has been shown to promote faster physiological recovery from acute stress. However, there is a paucity of research examining the potential inoculation effect of music on stress reactivity, as well as potential modifier’s that may influence this effect such as music selection and music absorption. Hence, the current study examined the potential inoculation effect of music in response to acute stress, as measured by a comprehensive set of stress indices. It was hypothesized that listening to music prior to acute stress exposure would decrease stress reactivity compared to white noise (WN), and that self-selected music (SSM) would serve as a stronger inoculator than researcher-selected music (RSM). Finally, it was hypothesized that music absorption would moderate the inoculation effect of music, with a greater decrease in stress reactivity observed in high absorbers. Exploratory sub-groups analyses were also performed to examine any potential age differences in the aforementioned associations. Participants were randomly assigned to either RSM (n = 37), SSM (n = 38), or a WN group (n = 33) and listened to either music or white noise prior to undergoing the Trier Social Stress Test (TSST). Outcome indices of stress included skin conductance, heart rate, salivary cortisol and self-report affect. Mixed analyses of covariance showed that music listening did not inoculate the stress response compared with WN and SSM did not serve as a more effective inoculator than RSM. A main effect of music absorption was found, suggesting that high absorbers are more reactive than low absorbers. Although the study hypotheses were not supported, exploratory sub-group analyses in older adults suggest that music listening and absorption may modulate the stress response. This study provides new insight into the effect of music listening on stress reactivity and presents a new line of questions that require further investigation.

Arithmetic Task

One of the most common methods of inducing stress in the laboratory in order to examine the stress response in healthy and clinical populations is the Trier Social Stress Test (TSST). Briefly, the participant is asked to deliver a speech and to perform an arithmetic task in front of an evaluating committee. The committee, consisting of three trained actors, does not respond emotionally during the test, which makes the situation very stressful for the participant. One disadvantage of the TSST is that it can be difficult to hold the experimental conditions constant. In particular, it may be difficult for actors to hold their acting constant across all sessions. Furthermore, there are several practical problems and costs associated with hiring professional actors. A computerized version of the TSST using virtual humans could be a way to avoid these problems provided that it is able to induce a stress response similar to the one of the original TSST. The purpose of the present pilot study was therefore to investigate the stress response to a virtual reality (VR) version of the TSST visualized using an immersive VR system (VR-TSST). Seven healthy males with an average age of 24 years (range: 23–26 years) performed the VR-TSST. This included delivering a speech and performing an arithmetic task in front of an evaluating committee consisting of three virtual humans. The VR equipment was a CAVE equipped with stereoscopy and head tracking. ECG and respiration were recorded as well as the participant's behavior and comments. Afterward, a semi-structured interview was carried out. In general, the subjective and physiological data from the experiment indicated that the VR version of the TSST induced a stress response in the seven participants. In particular, the peak increase in heart rate was close to rates observed in studies using the traditional TSST with real actors. These results suggest that virtual humans visualized with an immersive VR system can be used to induce stress under laboratory 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 or used CR to regulate their response to negative and neutral pictures and provided ratings of their negative affect in response to each picture. Half of the participants experienced an fMRI-adapted acute psychosocial stress manipulation similar to the Trier Social Stress Test, and a control group received parallel manipulations without the stressful components. Relative to the control group, the stress group exhibited heightened stress as indexed by self-report, heart rate, and salivary cortisol throughout the scan. Contrary to our hypothesis, we found that reappraisal success was equivalent in the control and stress groups, as was electrodermal response to the pictures. Heart rate deceleration, a physiological response typically evoked by aversive pictures, was blunted in response to negative pictures and heightened in response to neutral pictures in the stress group. In the brain, we found weak evidence of stress-induced increases of reappraisal-related activity in parts of the PFC and left amygdala, but these relationships were statistically fragile. Together, these findings suggest that both the self-reported and neural effects of CR may be robust to at least moderate levels of stress, informing theoretical models of stress effects on cognition and emotion.

Abstract. Acute stress and chronic stress change the physiology and function of the individual. As one facet, stress and its neuroendocrine correlates – with glucocorticoids in particular – modulate memory in a concerted action. With respect to working memory, impairing effects of acute stress and increased levels of glucocorticoids could be expected, but empirical evidence on moderating effects of cortisol on working memory is ambiguous in human studies. In the current study, we thus aimed to investigate cortisol stress responses and memory performance. Older men and women (32 men, 43 women, aged 61–67 years) underwent the Trier Social Stress Test (TSST) and performed the 2-back task before and after exposure to acute stress. In line with theoretical assumptions, we found that higher cortisol stress responses led to a decline of working memory performance in men. However, the opposite was evident for women, who appeared to benefit from higher stress responses. This effect was evident for accuracy, but not for reaction time. In conclusion, cortisol might mediate working memory alterations with stress in a sex-specific manner in older people. Possible mechanisms and causes for these sex differences put a focus on endocrine changes in the aging population that might lead to differential effects across the lifespan.

Metabolic Properties

The endocrine stress response helps to maintain homeostasis at times of increased demand and supports survival through energy mobilization. Paradoxically, low blood glucose levels impede the endocrine stress response, yet increasing blood glucose levels through sugar consumption prior to stress restores it. This suggests that glucose availability may play a causal role in the endocrine stress response. However, sugar has other distinct properties beyond the raise of blood glucose concentration. Here, we investigated the potential role of sweetness in restoring the cortisol stress reactivity after fasting. N=152 women (mean(age)=21.53, sd(age)=2.61) participated in a psychosocial stress test for groups in the morning after an overnight fast. Prior to stress induction, participants either consumed a drink that contained a caloric sweetener (sugar, n=51), an equally sweet drink containing non-caloric sweetener (sweetener, n=46), or water (n=56). Salivary cortisol and blood glucose levels were assessed repeatedly. Former studies suggested that sugar load prior to stress leads to increased cortisol responses compared to water, and sweetener. The effects of the consumed drinks on cortisol trajectories were tested using multilevel mixed models. Unexpectedly, we found that sugar and sweetener each significantly increased cortisol stress reactivity compared to water. Indeed, sweetener lead to cortisol increases comparable to sugar. Changes in blood glucose levels after drink consumption were not significantly associated with stress-induced increases in cortisol. This suggests that not the metabolic properties of sugar, but properties of sweet taste prior to stress are critical to boost the endocrine stress response to stress.
