Acute stress and human spatial working memory strategy use.

Acute stress can impair human working memory. Little is known, however, about the effects of acute stress on working memory strategies. The goal of this research was to investigate the effects of acute stress on use of a systematic spatial working memory search strategy. Participants (28 females and 20 males per group) completed the Trier Social Stress Test (TSST) or control tasks. Use of a systematic spatial working memory search strategy was measured through performance on the spatial working memory subtest of the Cambridge Neuropsychological Test Automated Battery (CANTAB). The TSST was effective at producing subjective and cortisol stress responses, but there was no significant stress effect on use of a systematic search strategy or working memory search errors. There were also no significant relationships between subjective and cortisol stress responses and use of a systematic search strategy or working memory search errors within the stress group. These results suggest that acute stress does not impair the self-generation or execution of a systematic spatial working memory search strategy.

Changes in subjective stress experiences and self-efficacy beliefs of preschool teachers in Germany: A longitudinal study during 12 months of the COVID-19 pandemic.

This study collected monthly data between September 2020 and August 2021 to document the consequences of the COVID-19 pandemic for German preschool teachers during different pandemic phases. This longitudinal study investigated how subjective stress experiences and self-efficacy beliefs of preschool teachers (N = 279) change over time and explored associations on the inter- and intraindividual level. We observed phase-specific changes in subjective stress experiences and interindividual differences in change rates, but no systematic increase across the entire study period. Results also highlight self-efficacy beliefs as a resource for preschool teachers, which should be strengthened to better face stress experiences.

Subjective stress and proactive and reactive cognitive control strategies.

Acute stress likely impacts cognitive control. Little is known, however, about the effects that acute stress may have on specific cognitive control strategies. The goal of this research was to investigate the effects of acute stress on proactive and reactive control strategies. Participants completed the Trier Social Stress Test or control tasks. Use of proactive and reactive control strategies was measured with the AX-Continuous Performance Test. The Trier Social Stress Test was effective at producing subjective, cortisol, and heart rate stress responses, but there was no significant effect of stress on use of proactive or reactive control strategies in between-group analyses. However, higher subjective stress responses during performance of the AX-Continuous Performance Test were associated with less frequent use of a proactive control strategy and more frequent use of a reactive control strategy within the stress group.

Reward anticipation buffers neuroendocrine and cardiovascular responses to acute psychosocial stress in healthy young adults.

Research over the last 10 years suggests that the brain's reward system plays a crucial role in stress resilience. Notably, reward processing includes both an anticipatory (cue-triggered "wanting") phase and a consummatory ("liking") phase. However, previous studies manipulated rewards via direct reward administration, which makes it difficult to isolate the buffering effect of anticipating the reward stimulus. In the current study, we designed a paradigm to manipulate participants into generating reward anticipation or not and investigated whether reward anticipation can buffer psychological, neuroendocrine, and cardiovascular responses to psychosocial stress. A sample of 78 healthy young adults underwent the Trier Social Stress Test or placebo-Trier Social Stress Test after a reward anticipation task. Results showed that reward anticipation relieved subjective stress feelings, as well as the overall cortisol secretion and the increased heart rate induced by psychosocial stress. Taken together, these findings expanded our understanding of the role the reward system plays in stress resilience, and the possible psychological mechanism of the buffering effect for future stress study was also discussed.HIGHLIGHTSReward processing includes both an anticipatory and consummatory phasesThe buffering effect of anticipating the reward stimulus requires elucidationWe examined if said anticipation buffers varied responses to psychosocial stressReward anticipation relieved subjective stress, cortisol secretion, and heart rateWe clarified the role of the reward system in stress resilience.

[Working modes and evaluation of perceived stress during the Covid-19 pandemic]. / Modalità di lavoro e valutazione dello stress percepito durante la pandemia di Covid-19.

SUMMARY: Introduction. The global sanitary crisis due to covid 19 has had an unprecedent impact on human health and on the global economy creating unexpected challenges on work life. In Italy in order to limit the velocity of virus transmission, measures aimed towards social distancing were adopted by suspending all non essential working activities, with the recommendation of the maximum use of smart working (DPCM 01 MARCH 2020). Literature regarding precedent experiences worldwide on the impact of epidemic or pandemic flu viruses on the working enviroment report of a strong presence of correlated work stress. Objectives. The study is focalized in identifying the individual stress level correlated to work percieved in workers in the context of the unexpected scenario in adapting to work in a short time period relative to the emergency context. Materials and Methods. An epidemiological observational survey was conducted on the web during the months of May and June. The workers were invited in answering a questionnaire using a dedicated link. The questionnaire consisted in a introductive scheme(card) built ad hoc for the study containing information for the socio-demographic variables and work experience. The Evaluation Rapid Stress scale (VRS) was used for the rating of the subjective stress. The t Student test was used for the independant samples in the assay for the average scores of the VRS for sex and age. The ANOVA test was used in order to compare the various scores of the VRS in the three different working modes investigated (work on site, smart working or for both the modalities). A p0.05 was considered as level of significance. The statistical assay was conducted with the STATA software packet. Results. 337 workers answered the questionnaire. The rating of the VRS scores for sex highlighted significative differences between men and women in the levels of anxiety, depression, somatization and aggression showing higher values in women. The highest total scores of the VRS questionnaire and those related to the anxiety and somatization dimensions express higher levels of stress levels in response to the emergency situation in workers who carry out their activity in a on-site mode over the age of 40 and in parents. The comparison with the scores reported between the different working modes was resulted statistically significant. Conclusions. The results of our investigation are an expression of the perception of a widespread danger, linked to the threat of contracting the COVID-19 virus, whose mode and speed of transmission is surprising and for which therapy and in definitive treatment is not yet available. This leads to a series of emotional reactions in which stress is the main condition. The timely exploration aimed at the individuation of a stress problem in the working environment is extremely important especially in emergency situations in order to implement appropriate strategies of prevention.

Cumulative cortisol concentrations in hair of patients with atopy are lower than in healthy subjects and are not related to their perceived stress experience.

Patients with atopy were found to exhibit blunted cortisol responses to acute stress stimuli. The aim of this study was to test the hypothesis that cumulative cortisol concentrations in the hair of patients with atopy are lower than in healthy subjects when related to their perceived stress experience. The sample consisted of 31 participants. The most proximal 3 cm of hair (as close to the scalp as possible), reflecting the cumulative cortisol secretion during the previous 3 months, was used for the analysis. Only in 20 subjects (9 patients with atopy and 11 healthy controls), there was a sufficient amount of hair for precise analysis using a new methodology. The results showed lower hair cortisol concentrations in patients with atopy compared to those in controls. The perceived stress scores in patients with atopy and healthy controls were not statistically different. The cortisol concentration/perceived stress score ratios were lower in patients with atopy compared to those in controls. No statistically significant correlation between hair cortisol and long-term experienced stress assessed via perceived stress scale was observed. In conclusion, the cumulative cortisol secretion in the hair of atopic patients is lower than would be expected according to their subjective scores of perceived stress. Most importantly, the previously lower stress hormone increase found in acute stress situations and in children now was confirmed in adult patients with chronic stress load.

Individual Differences in the Association Between Subjective Stress and Heart Rate Are Related to Psychological and Physical Well-Being.

The physiological response to stress is intertwined with, but distinct from, the subjective feeling of stress, although both systems must work in concert to enable adaptive responses. We investigated 1,065 participants from the Midlife in the United States 2 study who completed a self-report battery and a stress-induction procedure while physiological and self-report measures of stress were recorded. Individual differences in the association between heart rate and self-reported stress were analyzed in relation to measures that reflect psychological well-being (self-report measures of well-being, anxiety, depression), denial coping, and physical well-being (proinflammatory biomarkers interleukin-6 and C-reactive protein). The within-participants association between heart rate and self-reported stress was significantly related to higher psychological well-being, fewer depressive symptoms, lower trait anxiety, less use of denial coping, and lower levels of proinflammatory biomarkers. Our results highlight the importance of studying individual differences in coherence between physiological measures and subjective mental states in relation to well-being.

Stability and change of postchemotherapy symptoms in relation to optimism and subjective stress: A prospective study of breast cancer survivors.

OBJECTIVES: Inconsistent findings were reported about the course of postchemotherapy symptoms; specifically, the effect of changes in optimism and perception of subjective stress on the evolution of symptoms remains understudied. This prospective study aimed (a) to examine the course of postchemotherapy symptoms of emotional distress, fatigue, and cognitive difficulties among breast cancer survivors and (2) to assess the effect of changes in optimism and subjective stress on the trajectory of these symptoms. METHODS: Ninety-eight breast cancer survivors, diagnosed at stages I to III, aged 30 to 74, recruited consecutively (response rate 84.7%) completed fatigue, emotional distress, self-reported cognitive difficulties, optimism, and subjective stress questionnaires at three points in time: upon enrollment (1-6 months after completing treatment, Time 1) posttreatment, 6 months (Time 2), and 12 months (Time 3). A linear mixed-effects model was used to analyze the data. RESULTS: Emotional distress decreased between time-points, level of cognitive difficulties remained stable, and a marginal decrease in fatigue was evident. Optimism or subjective stress predicted changes in each of the symptoms (P<.01), except for the effect of optimism on cognitive difficulties (P=.06). The interactions between time and optimism and between time and subjective stress were only significant regarding their effect on emotional distress (P<.05), showing that the strongest effect of these variables was at Time 2. CONCLUSION: The course of postchemotherapy symptoms shows patterns of stability and change over a 1-year period. Optimism and subjective perceptions of stress were shown to affect the decrease of symptoms. Therefore, these two factors should be specifically targeted in psycho-social interventions.

Understanding stress reports in daily life: a coordinated analysis of factors associated with the frequency of reporting stress.

Although stress is a common experience in everyday life, a clear understanding of how often an individual experiences and reports stress is lacking. Notably, there is little information regarding factors that may influence how frequently stress is reported, including which stress dimension is measured (i.e., stressors-did an event happen, subjective stress-how stressed do you feel, conditional stress-how stressful a stressor was) and the temporal features of that assessment (i.e., time of day, day of study, weekday vs. weekend day). The purpose of the present study was to conduct a coordinated analysis of five independent ecological momentary assessment studies utilizing varied stress reporting dimensions and temporal features. Results indicated that, within days, stress was reported at different frequencies depending on the stress dimension. Stressors were reported on 15-32% of momentary reports made within a day; across days, the frequency ranged from 42 to 76% of days. Depending on the cutoff, subjective stress was reported more frequently ranging about 8-56% of all moments within days, and 40-90% of days. Likewise, conditional stress ranged from just 3% of moments to 22%, and 11-69% of days. For the temporal features, stress was reported more frequently on weekdays (compared to weekend days) and on days earlier in the study (relative to days later in the study); time of day was inconsistently related to stress reports. In sum, stress report frequency depends in part on how stress is assessed. As such, researchers may wish to measure stress in multiple ways and, in the case of subjective and conditional stress with multiple operational definitions, to thoroughly characterize the frequency of stress reporting.

Exploring the multidimensional complex systems structure of the stress response and its relation to health and sleep outcomes.

To gain a comprehensive understanding of the multidimensional complex systems structure of the stress response and related health outcomes, we utilized network analysis in a sample of 328 healthy participants in two steps. In a first step, we focused on associations between measures of basal hypothalamic-pituitary-adrenal axis functioning and subjective stress perceptions. In a second step, we linked these diverse stress-related measures to biomarkers and self-reports of health and sleep. Overall, measures clustered depending on their method of assessment, with high correlations between different saliva-based indices of diurnal cortisol regulation, between cortisol and cortisone levels in hair, between different biological health indicators (systemic inflammatory activity and body mass index), between state (experience sampling) and trait (questionnaire-based) self-reports of stress and wellbeing, and between different self-reports of sleep. Bridges between clusters suggested that if individuals perceive stress throughout their daily lives this is reflected in their total salivary cortisol output possibly contributing to long-term cortisol accumulation in hair. Likewise, earlier awakening time may contribute to cortisol accumulation in hair via an influence on awakening cortisol processes. Our results show that while meaningful connections between measures exist, stress is a highly complex construct composed of numerous aspects. We argue that network analysis is an integrative statistical approach to address the multidimensionality of the stress response and its effects on the brain and body. This may help uncover pathways to stress-related disease and serve to identify starting points for prevention and therapeutic intervention.

Work related stress and blood glucose levels.

AIM: The aim of the study is to evaluate work-related subjective stress in a group of workers on a major Italian company in the field of healthcare through the administration of a valid "questionnaire-tool indicator" (HSE Indicator Tool), and to analyze any correlation between stress levels taken from questionnaire scores and blood glucose values. MATERIAL AND METHODS: We studied a final sample consisting of 241 subjects with different tasks. The HSE questionnaire - made up of 35 items (divided into 7 organizational dimensions) with 5 possible answers - has been distributed to all the subjects in occasion of the health surveillance examinations provided by law. The questionnaire was then analyzed using its specific software to process the results related to the 7 dimensions. These results were compared using the Pearson correlation and multiple linear regression with the blood glucose values obtained from each subject. RESULTS: From the analysis of the data the following areas resulted critical, in other words linked to an intermediate (yellow area) or high (red area) condition of stress: sustain from managers, sustain from colleagues, quality of relationships and professional changes. A significant positive correlation (p <0.05) between the mean values of all critical areas and the concentrations of glucose values have been highlighted with the correlation index of Pearson. Multiple linear regression confirmed these findings, showing that the critical dimensions resulting from the questionnaire were the significant variables that can increase the levels of blood glucose. CONCLUSION: The preliminary results indicate that perceived work stress can be statistically associated with increased levels of blood glucose.

Associations of hair cortisol concentration with self-reported measures of stress and mental health-related factors in a pooled database of diverse community samples.

A pooled database from diverse community samples was used to examine the associations of hair cortisol concentration (HCC) with self-reported stress and stress-linked mental health measures, including depression, anxiety, alcohol and drug use, disability and experiences with aggression. As part of innovative research using a mobile laboratory to study community mental health, data were pooled from five sub-studies: a random sample of the general population (n = 70), people who had received treatment for a mental health and/or substance use problem (n = 78), family members of people treated for mental health and/or substance use problems (n = 49), community volunteers who sometimes felt sad or blue or thought they drank too much (n = 83) and young adults in intimate partner relationships (n = 44). All participants completed a computerized questionnaire including standard measures of perceived stress, chronic stress, depression, anxiety, hazardous drinking, tobacco use, prescription drug use, illicit drug use, disability and intimate partner aggression. HCC was significantly associated with use of antidepressants, hazardous drinking, smoking and disability after adjusting for sub-study and potential confounders (sex, body-mass index, use of glucocorticoids and hair dyed). In addition, preliminary analyses suggest a significant curvilinear relationship between HCC and perceived stress; specifically, HCC increased with higher perceived stress but decreased at the highest level of stress. Overall, HCC was associated with mental health-related variables mainly reflecting substance use or experiencing a disability. The relationship between HCC and self-reported stress is unclear and needs further research.

Derailment is associated with increased depressed mood at lower levels of stress: An experimental approach.

BACKGROUND: As an emergent developmental construct, derailment - an individual difference hallmarked by a temporal discordance of the self - has been positively associated with depressive features, though less is known about the role of stress in this relationship. The aim of the present study was to explore the interaction between derailment and subjective stress on depressed mood. METHODS: 265 adults recruited through Prolific - a crowd sourcing platform were first tasked with completing baseline measures, then were randomly assigned to a low stress or high stress condition. We utilized an adapted version of the Online Trier Stress Test to manipulate stress levels. Next, depressed mood and post-test perceived stress were measured. We analyzed data through STATA using a two-tailed independent samples t-test and multiple linear regression. RESULTS: Findings suggested the experimental manipulation increased subjective stress within the high stress condition compared to the low stress condition (Mdiff = 36.14, SE = 4.4, t = 8.21, p < .001). Further, we found the interaction between derailment and stress conditions was associated with increased depressed mood (ß = -0.11, SE = 0.05, p = .038, R2 = 0.5). Notably, we found significant between-condition differences in depressed mood for those who endorsed either low (d = 0.22, SE = 0.07, p = .003) or moderate levels of derailment (d = 0.11, SE = 0.05, p = .033), but not for those who endorsed high levels of derailment (d = 0.01, SE = 0.07, p = .92). LIMITATIONS: This study utilized self-report measures, which may be susceptible to biased responses. CONCLUSIONS: Derailment may play a role in the persistence of depressed mood regardless of varying contexts of stress.

Association between lifestyle factors and hypertension control in Indonesian primary healthcare settings: A cross-sectional study.

Introduction: A healthy lifestyle influences hypertension control. However, studies investigating the effects of lifestyle on hypertension remain elusive. This study aimed to analyse the association between lifestyle factors and hypertension control among patients with hypertension. Methods: This cross-sectional exploratory study was conducted from June to December 2022 among 265 patients with hypertension from the Pusat Kesehatan Masyarakat. The status of hypertension control was assessed by checking the serial blood pressure. The physical activity (PA) level, sleep quality, stress level and eating pattern were measured using the Global Physical Activity Questionnaire; Pittsburgh Sleep Quality Index; Depression Anxiety Stress Scale-21; and 24-Hour Food Recall Questionnaire, Adolescent Food Habits Checklist and Emotional Eating Scale, respectively. Stepwise binary logistic regression and a generalised linear model were used for the statistical analysis. Results: Approximately 72.2% of the participants had uncontrolled hypertension. The majority showed a low PA level (46%), normal stress level (94.7%), good sleep quality (80%), low caloric intake (95.5%), neutral food habit (55.5%) and low emotional eating (93.2%). Sex (P=0.030), age (P=0.018), PA level (P=0.011), sleep quality (P=0.032) and stress level (P=0.030) significantly influenced hypertension control. Specifically, moderate (odds ratio [OR]=5.868, 95% confidence interval [CI]=3.024-11.798, P=0.000) and vigorous PA levels (OR=2.188, 95% CI=1.026-4.678, P=0.042) were significantly associated with hypertension control. Conclusion: Moderate and vigorous PA levels are lifestyle factors that may play a role in controlling hypertension.

Purpose in life and stress: An individual-participant meta-analysis of 16 samples.

Background: Purpose in life is a psychological resource that has been associated with better regulation of stress. The present research reports a coordinated analysis of the association between purpose in life and subjective stress and evaluates potential sociodemographic and mental health moderators of this association. Methods: With individual participant data from 16 samples (total N=108,391), linear regression examined the association between purpose in life and general subjective feelings of stress, controlling for sociodemographic characteristics. Results: Greater purpose in life was associated with less subjective stress (meta-analytic estimate=-.228, 95% Confidence Interval=-.292, -.164; p<.001). Interaction terms between sociodemographic factors and purpose tested in the individual samples and synthesized with meta-analysis were not significant, which indicated that the association between purpose and stress was similar across age, sex, race, ethnicity, and education. The association was also not moderated by psychological distress. Meta-regressions further indicated that this association was generally similar across scale length, content of the purpose measure, and across samples from Eastern and Western countries. Limitations: The associations reported are observational. Experimental work is needed to evaluate causality. Conclusions: Purpose in life is associated with less subjective stress across populations. Less subjective stress may be one mechanism through which purpose contributes to better mental and physical health.

Native Hawaiian and Pacific Islanders' Identity and Housing Status: The Impact on Historical Trauma and Perceived Stress.

Native Hawaiian and Pacific Islanders (NHPIs) are overrepresented in Hawai'i's houseless population. Indigenous populations, such as NHPIs, may encounter experiences of historical trauma that impact their well-being. This original research project examines how NHPI identity and houselessness compound to affect the perceived stress and historical trauma of transition-aged youth. Fifty-one participants aged 18 to 24 (M = 21.37, SD = 1.93) completed a survey that included the historical traumatic events scale, historical loss scale, perceived stress scale, and a demographic questionnaire. Over half (n = 26, 51.0%) of the participants identified as NHPI. A two-way ANOVA indicated a non-significant effect of NHPI identity and housing status on perceived stress. However, housed participants scored significantly higher than participants experiencing houselessness on the historical traumatic events scale (p = 0.006). Our findings elucidate the role of knowledge in the experience of historical trauma. Further results, limitations, and future directions are offered.

Impact of psychosocial stress on facial emotion recognition in schizophrenia and controls: an experimental study in a forensic sample.

Introduction: Psychotic disorders have been associated with dysregulated stress reactions and adaptation. Little is known about the neuroendocrine responses to psychosocial stress in justice-involved individuals with schizophrenia. Methods: Using an experimental research design, the present study aims to examine differences in the subjective and neuroendocrine responses to psychosocial stress and its impact on facial emotion recognition (FER) and performance on an arithmetic task in chronically ill justice-involved individuals with schizophrenia (PAT) and a healthy control group. PAT undergoing treatment in forensic psychiatric inpatient wards (n = 17) and a healthy control group (n = 17) were assessed regarding sociodemographic and clinical characteristics. Additionally, salivary cortisol levels, measured before and after performing a psychosocial stress task [Montreal Imaging Stress Task (MIST)], and performance on an arithmetic problem-solving task and two FER tasks were recorded. Two participants dropped out, one from each group. Therefore, the final sample consisted of 32 individuals. Results: Significant group differences in FER were recorded. There was a significant rise in subjective perception of momentary strain relating to the induction of psychosocial stress in both groups. Notably, the pre-stress level of subjective strain was higher in the PAT group than controls. Acute psychosocial stress induced an increase in FER performance in a sub-task related to naming emotions in individuals with schizophrenia spectrum disorder. Discussion: The results underline the importance of psychosocial and therapeutic interventions aimed at strengthening stress resilience in individuals with schizophrenia spectrum disorders.

Psychophysiological and stress responses to competition in team sport coaches: an exploratory study.

Examinations of stress in coaches have mainly been qualitative and focused on chronic stressors. This exploratory study examined stress responses in coaches during competition, including psychological and physiological indices. Using reversal theory, we examined metamotivational state profiles during competition. Ten male team sport coaches (mean age 39.8 ± 13.12 years) reported levels of subjective stress, pleasant and unpleasant emotions, metamotivational state, and provided saliva samples, on a competition day: 15 min prior to the pre-match team talk; start of the match; end of the first half; start of the second half, and end of the match, then at equivalent times on a noncompetition day. Saliva samples were assayed for alpha-amylase activity. On competition day, alpha-amylase activity was significantly higher, as were subjective stress, arousal, and unpleasant emotions. Prior to and during active play, participants were mainly in the conformist, alloic (other-oriented), and mastery states, and at the end of the match, in the telic and sympathy states. Only 22 metamotivational state reversals were observed, mostly at the start and end of the match. The elevated levels of subjective stress, alpha-amylase activity, and unpleasant emotions suggest that educational programs may be useful for some coaches to manage psychological states during competition.

How much stressful life events really matter? Conceptual and methodological difficulties in assessing the impact of self-reported events on adolescents' subjective stress.

Numerous studies have pointed to the strong impact of stressful life events on subjective stress and indirectly on the adolescents' mental health. However, the results of many such studies contain bias caused by the choice of measurement method or an incomplete theoretical framework. To estimate the extent of possible bias when using self-reports, we conducted research on a representative sample of 2201 Croatian adolescents aged 14-18 years. Using manipulation we examined the influence of measurement method and the number of constructs included in the model on the variance of subjective stress explained by stressful events. Structural equation modelling indicated that different measurement methods, occurrence-based and severity-based, provide a marked discrepancy in the impact size estimation. The occurrence-based method provided estimates of a much smaller proportion of the explained variance (6%-25%) compared to the severity-based approach, which estimated the explained variance in the range of 25%-55% depending on the model. The complexity of the tested models additionally contributed to the variation in the estimates. It is recommended that when using self-reports to measure stressful life events, occurrence-based and severity-based methods are used simultaneously and that impact estimates are expressed within intervals.

Beyond the RewP: The reward feedback-elicited LPP and its potential associations with perceived stress and internalizing symptoms in late childhood.

Internalizing problems increase substantially during late childhood and early adolescence, which are known to be associated with elevated perceived stress as children transition into adolescence. One risk factor that may moderate the stress-symptom association is reward processing. While neurophysiological research in this field has focused on the reward positivity component (RewP) elicited during reward processing, little work has examined the reward feedback-elicited late positive potential (LPP) and its association with internalizing psychopathology. The present study examined the moderating roles of the RewP and feedback-elicited LPP in the relationship between perceived stress and internalizing symptoms in late childhood. A community sample of 115 nine-to-12-year-old children (66 girls, Mean age = 11.00 years, SD = 1.16) completed an EEG version of the reward feedback paradigm, the Doors task, and completed questionnaires on perceived stress and internalizing symptoms. A principal component analysis revealed three temporo-spatial factors that were temporally and spatially analogous to the RewP, anterior LPP, and posterior LPP, respectively. As expected, an enlarged RewP was found towards the win condition compared to the loss condition. We also observed a potentiated LPP towards loss relative to win feedback, which may reflect the evaluation and reappraisal processes following unsuccessful performance (i.e., loss). We did not, however, find significant moderating effects of any ERP components on the stress-symptom association. Our study was first to isolate the feedback-elicited LPP in a reward processing paradigm in children and provide initial evidence on the modulation of the ERP component by task conditions. Future research is warranted to further explore the functional significance of the reward feedback-elicited LPP in association with perceived stress and internalizing psychopathology in youths.
