ObjectiveThis study compared the effects of prior cognitive, physical, and concurrent exertion on physical performance.BackgroundFatiguing cognitive and physical exertions have been shown to negatively affect subsequent task performance. However, it is not clearly understood if concurrent physical and cognitive effort may exaggerate the negative carryover effects on physical task performance when compared to cognitive or physical exertion alone.MethodTwenty-five participants completed four isometric handgrip endurance trials on different days. The endurance trials were preceded by four, 15-minute experimental manipulations (cognitive, physical, concurrent, control). Electromyography (EMG) and force tracing performance were monitored, with handgrip strength measured pre and post. Subjective ratings of mental and physical fatigue, as well as affect, motivation, and task self-efficacy, were also assessed.ResultsHandgrip strength decreased following both physical (-14.4% MVC) and concurrent (-12.3% MVC) exertion manipulations, with no changes being observed for the cognitive and control conditions. No differences were observed across conditions for endurance time, EMG, nor tracing performance. When compared to the control conditions, perceptions of mental and physical fatigue were higher following the experimental manipulation. Endurance trial self-efficacy was lower for the mental, physical and concurrent conditions compared to control.ConclusionThe concurrent condition resulted in similar decreases in strength as the physical fatigue condition, but otherwise resulted in similar carryover effects on endurance performance across all conditions. Further study is required at higher exposure levels, or for longer exposure durations, to further probe the influence of concurrent physical and cognitive effort on task performance.ApplicationConcurrent cognitive and physical effort resulted in similar physical performance decrements to physical effort alone.

The study's main goal was to investigate the effect of ego depletion on explicit and implicit attitudes and behavior toward sustainable food consumption in the context of dual-process models describing sustainable behavior.

171 student participants completed an explicit rating and an affective priming task, respectively, at pre- and post-intervention, namely a six-minute transcription task to induce ego depletion. They then conducted a decision-making task (sustainable vs. less-sustainable chocolate bar) to test sustainable behavior during ego depletion.

Contrary to our hypotheses, explicit attitudes toward sustainable nutrition remained stable across conditions, showing no significant decline in the depletion group. Unexpectedly, implicit attitudes toward sustainable vegetarian nutrition became more negative over time, irrespective of the experimental condition. In the decision-making task, participants' behavior was primarily predicted by their explicit attitudes post-intervention, rather than their implicit attitudes or ego depletion state.

These findings challenge the assumption that ego depletion weakens explicit attitudes toward sustainable behavior, particularly vegetarian nutrition. Instead, explicit attitudes appear to be stable and the predominant predictor of sustainable food choices.

Physical activity is associated with social network site addiction in adolescents, yet the mechanisms remain unclear. This study examines whether anxiety and ego-depletion mediate this relationship.

A survey was conducted among 1,174 Chinese adolescents (614 boys, 560 girls; mean age = 12.59, SD = 1.13). Physical activity was assessed with a single item on moderate-to-vigorous exercise in the past 7 days. Social network site addiction, anxiety, and ego-depletion were measured using validated self-report questionnaires. Descriptive statistics, correlation analyses, and a chained mediation model were employed.

Physical activity was negatively correlated with social network site addiction (r = -0.165, p < 0.001), anxiety (r = -0.121, p < 0.001), and ego-depletion (r = -0.119, p < 0.001). Anxiety was positively correlated with ego-depletion (r = 0.574, p < 0.001) and social network site addiction (r = 0.388, p < 0.001). Ego-depletion was positively associated with social network site addiction (r = 0.456, p < 0.001). Anxiety and ego-depletion sequentially mediated the relationship between physical activity and social network site addiction.

This study clarifies the psychological mechanisms linking physical activity and social network site addiction in adolescents, identifying anxiety and ego-depletion as key mediators. The findings emphasize the need to target these factors for more effective interventions.

Problematic gaming is becoming increasingly prevalent among young people, often leading to negative developmental consequences. As an essential protective factor against problematic gaming, self-control is the capacity to manage emotions, thoughts, and actions when confronted with temptations and impulses. Previous studies have reported mixed findings regarding the association between problematic gaming and self-control. The current systematic review and meta-analysis synthesized the existing literature on this relationship among adolescents and emerging adults. A systematic search from eight electronic databases (PsycArticles, PsycINFO, EBSCOhost, Web of Science, PubMed, Embase, ProQuest Dissertations & Theses A&I, and China Academic Journal Network Publishing Database) and two additional sources (Google Scholar and reference lists) identified 957 published studies. Of these, 46 articles involving 64,681 participants were included in the review, and 40 provided sample size and Pearson's r for the meta-analysis. The narrative review findings indicated that problematic gaming was negatively correlated with self-control with only two studies suggesting an insignificant relationship. The meta-analytic findings, conducted using a random-effects model in Comprehensive Meta-Analysis Software Version 4.0, revealed a medium effect (r = -0.287, 95% CI = [-0.33, -0.25], p < 0.001), with high heterogeneity (I2 = 96.5%). Publication bias analysis showed a symmetric funnel plot and a nonsignificant Egger's test (p = 0.861), indicating no evidence of publication bias. No significant subgroup difference was found between adolescents and emerging adults. The results reveal that self-control is a critical factor in preventing and intervening problematic gaming.

The present study aimed to investigate the effects of anonymity and moral emotions on college students' deceptive behavior under different ego depletion conditions.

In Experiment 1, 120 college students were recruited and assigned to a 2 (ego depletion: high vs. low) × 2 (anonymity: anonymous vs. non-anonymous) between-participants design to examine the impact of anonymity on deceptive behavior under varying levels of ego depletion. In Experiment 2, 150 college students were recruited and assigned to a 2 (ego depletion: high vs. low) × 3 (moral emotions: positive vs. negative vs. neutral) between-participants design to investigate the effects of moral emotions on deceptive behavior under different ego depletion conditions.

In Experiment 1, results revealed a significant main effect of ego depletion: the high ego depletion group exhibited more deceptive behavior than the low ego depletion group, and their decision-making reaction times were shorter. The main effect of anonymity was also significant, with the anonymous group showing more deceptive behavior than the non-anonymous group. Moreover, a significant interaction effect was found; under high ego depletion conditions, the anonymous group exhibited greater deceptive behavior than the non-anonymous group (all p < 0.001). In Experiment 2, the main effect of moral emotions was significant: the positive moral emotion group exhibited less deceptive behavior than the negative moral emotion group, which in turn exhibited less deceptive behavior than the neutral emotion group. Additionally, a significant interaction effect was found, under high ego depletion conditions, the positive moral emotion group demonstrated less deceptive behavior than the negative moral emotion group, which, in turn, demonstrated less deceptive behavior than the neutral emotion group (all p < 0.001).

The findings indicate that under high ego depletion conditions, college students engage in more deceptive behavior. Anonymity exacerbates the after-effects of ego depletion, leading to increased deception, whereas moral emotions help mitigate these after-effects and reduce deceptive behavior.

Organ donation and transplantation are vital for saving lives, yet awareness remains limited. Health literacy, the ability to understand and use health information, and self-control, which influences decision-making, are crucial factors in promoting awareness. Understanding their relationship can guide efforts to increase participation in organ donation.

To investigate the effect of health literacy on organ donation and transplantation awareness, with self-control acting as a mediator, and to emphasize its importance.

The study comprised 345 adults recruited from five different cities in Türkiye. The sample included 208 women (60.29%) and 137 men (39.71%). The age range of the sample group varies between 18 and 49 (median age = 24.13; SD = 8.81). Self-report data were collected including psychometric measures assessing organ donation and transplantation awareness, health literacy, and self-control. Reliability analysis, descriptive statistics, correlational analysis, and mediational analysis of the data were carried.

The analysis showed that health literacy was positively correlated with organ donation and transplantation awareness (r = 0.340) and self-control (r = 0.376). Self-control was positively related to organ donation and transplantation awareness (r = 0.531). Mediating analysis supported a mediation model where health literacy was found to influence organ donation and transplantation awareness via self-control (bootstrap = 0.158, 95% confidence interval = 0.105-0.215).

The results indicate that self-control mediates the positive relationship between health literacy and organ donation and transplantation awareness. Enhancing individuals' health literacy may therefore increase awareness of organ donation and transplantation through improvements in self-control.

Psychiatric symptoms such as depressed mood, feelings of worthlessness, and anxiety can be exacerbated in adolescents by online content that mirrors their negative emotions.1,2 In the authors' experience working on an inpatient unit, adolescents cite social media as a source of distress precipitating hospitalization. Moreover, screen time often becomes a point of family conflict, particularly during safety planning for discharge. Even when families agree on the need to address problematic mobile device use, algorithms driven by artificial intelligence (AI) are designed to hook users and curate content that feeds off negative emotional states and makes it challenging to break the cycle.3,4 We describe an intervention for interested families in our adolescent inpatient unit to support sustained change post discharge.

Self-control plays a crucial role in mitigating the negative effects of improper internet use, such as internet addiction. While the Brief Self-Control Scale (BSCS) has been widely employed to measure self-control, its items fail to adequately account for the specific challenges of internet use, and the dimensional structure of the BSCS remains unclear. Moreover, no psychometric validation of the adapted BSCS for internet use has been conducted. To address these gaps, this study adapted and validated a version of the BSCS specific to internet use. Data were collected from 6858 Chinese adolescents. Exploratory and confirmatory factor analyses revealed a three-factor structure of self-control in the context of internet use, which demonstrated good reliability, with a Cronbach's alpha of 0.818 and a McDonald's omega of 0.875. Measurement invariance was supported across age, but strict measurement invariance was not established across gender. Finally, we found that the second factor of self-control for internet use was significantly negatively correlated with the level of internet addiction. These findings confirm that the adapted BSCS exhibits satisfactory reliability and validity for assessing self-control in the context of internet use among Chinese adolescents.

The aim of this study was to explore health perceptions and self-defined facilitators to health in general population. An additional aim of the study was to assess if these perceptions were connected with the context of the Covid-19 pandemic.

We applied photo-elicitation method by gathering original photographs and narratives (captions) via social media and e-mails. Participants (N = 50) were asked to answer the question: 'What does it mean to be healthy?'. Data were collected online in Poland. We generated and interpreted the main themes associated with common perceptions of health and self-defined facilitators to health using polytextual thematic analysis.

The health perception themes were, health as: a 'long journey'; keeping balance; and self-acceptance. The main facilitators to health were: enjoyment of activities that are part of a healthy lifestyle; planning time for rest; contact with nature, and supportive relationships. Participants' perceptions of how Covid-19 impacted on their health differed.

The findings provide evidence for individual health perceptions and self-defined facilitators to health and can support the development of future health interventions.

Everybody knows intuitively what mental fatigue is. However, we poorly understand why fatigue emerges with time spent on demanding cognitive work and how such 'cognitive fatigue' impacts neural processing and behavioral guidance. Here, we review experimental investigations that induced cognitive fatigue and recorded its potential markers, including self-report, behavioral performance, economic choice, physiological and neural activity. We then review theoretical models of cognitive fatigue, classically divided into biological and motivational accounts. To explain key observations and reconcile debated theories, we finally propose a conceptual model (dubbed MetaMotiF), in which cognitive fatigue would emerge for biological reasons and yet affect motivational processes that regulate the behavior. More precisely, fatigue would arise from metabolic alterations in cognitive control brain regions, following their excessive mobilization. In turn, these metabolic alterations would increase the cost of cognitive control, which would shift decisions towards actions that require little effort and yield immediate rewards.

Although there are several guidelines in the literature on "recurrent abortion", there is no comprehensive guideline on "threatened abortion". The overall purpose of this guideline is to provide healthcare providers with the best available evidence for examination and treatment of pregnant women with threatened abortion.

The scope of the guideline and the first version of the questions were prepared by the Perinatology and High Risk Pregnancies Association (PERİDER) guideline development group in January 2024. Meetings were held to discuss key questions and redefine them. A final list of 8 key questions was created. Keywords were defined for each question and ranked in order of importance and used in searches for all English-language publications in PubMed/Medline and Cochrane libraries. These databases were thoroughly scanned for publications that were published until February 1, 2024. Literature reviews were conducted as an iterative process. In the first step, systematic reviews and meta-analyses were collected. If no results were found, the research was expanded to randomized controlled trials and then to cohort studies and case reports, following the hierarchy of evidence levels.

This guideline was presented to the board of directors of the Turkish Gynecology and Obstetrics Society (TJOD). With their suggestions, guideline was finalized, and it was decided to be published as a joint guideline of PERİDER-TJOD.

This guideline provides an overview of threatened abortion and the recommended treatments. In addition, by recognizing the deficiencies in the literature, suggestions were made regarding research that could help clinicians' decisions in the future.

This study investigates how functional, emotional, and social values shape Pilates participants' attitudes and behavioral intentions within an Extended Theory of Planned Behavior (ETPB) framework.

A survey was conducted with 288 Pilates participants, and structural equation modeling was employed to analyze the relationships among perceived value, attitude, subjective norms, perceived behavioral control, and behavioral intention.

The findings indicate that functional and social values positively influence attitudes, whereas emotional value has no significant effect. Moreover, subjective norms exert the strongest influence on behavioral intention, highlighting the importance of social factors in Pilates participation.

This study underscores the role of perceived value in shaping attitudes and confirms the dominant impact of subjective norms on behavioral intention. The findings offer theoretical contributions by refining the ETPB model and provide practical insights for enhancing engagement in Pilates programs.

This study contributes to the literature by applying an ETPB model to the context of Pilates, incorporating perceived value as an additional factor. It challenges the traditional emphasis on attitude as the primary predictor of behavioral intention by highlighting the dominant role of subjective norms. These insights offer a more nuanced understanding of the factors driving Pilates participation and provide practical implications for developing strategies to enhance engagement and retention in Pilates programs.

To explore the impact and mechanism of weight status on the disordered eating behavior of university students, this study conducted a moderated chain mediation model based on the Escape Theory and the Strength Model of Self-Control.

This was a cross-sectional online study conducted at a university in Shanghai. The questionnaire was distributed via communication tools such as WeChat from March 6 to 15, 2022, receiving 2618 valid responses. The moderated chain mediation model was empirically examined with 10,000 Bootstrap samples using AMOS software.

(1) Weight status can indirectly predict disordered eating behavior through the mediating effect of body dissatisfaction (β = 0.24, 95% CI: 0.22-0.26, p < 0.001); (2) Body dissatisfaction and negative affect play a chain mediation role in the positive impact of weight status on disordered eating behavior (β = 0.01, 95% CI: 0.01-0.02, p < 0.001); (3) Physical activity moderates the positive impact of negative affect on disordered eating behavior (Diff = -0.11, t = 2.20, p < 0.05) and further plays a moderating role in the chain mediation model (Diff = -0.01, t = 2.30, p < 0.05). Specifically, the higher the level of physical activity among university students, the weaker the impact of negative affect on disordered eating behavior, and the weaker the chain mediation effect; (4) The level of physical activity moderates the relationship between weight status, body dissatisfaction, and disordered eating, suggesting that the higher the level of physical activity, the stronger the mediating role of body dissatisfaction between weight status and abnormal eating (Diff = 0.12, t = 2.74, p < 0.05).

These findings revealed the pathways through which weight status affects the eating behavior of university students and how physical activity might weaken or strengthen this impact. This research supplements prior studies and offers insight into health promotion for university students.

The reward responsivity hypothesis of self-control proposes that irrespective of self-control success, exercising self-control is aversive and engenders negative affect. To countermand this discomfort, reward-seeking behavior may be amplified after bouts of self-control, bringing individuals back to a mildly positive baseline state. Previous studies indicated that effort-an integral component of self-control-can increase reward responsivity. We sought to test and extend the reward responsivity hypothesis by asking if exercising self-control increases a neural marker of reward responsivity [Reward Positivity (RewP)] differentially for hedonic rewards or eudaimonic rewards. We instructed participants (N = 114) to complete a speeded reaction time task where they exercised self-control (incongruent Stroop trials) or not (congruent Stroop trials) and then had the opportunity to win money for themselves (hedonic rewards) or a charity (eudaimonic rewards) while electroencephalography was recorded. Consistent with the reward responsivity hypothesis, participants evinced a larger RewP after exercising self-control (vs. not exercising self-control). Participants also showed a larger RewP for hedonic over eudaimonic rewards. Self-control and reward type did not interactively modulate RewP, suggesting that self-control increases reward responsivity in a domain-general manner. The findings provide a neurophysiological mechanism for the reward responsivity hypothesis of self-control and promise to revitalize the relevant literature.

Occupational fraud presents significant economic challenges globally. This study aims to understand the factors contributing to such fraudulent behavior and to develop strategies to mitigate it, focusing on the relationship between gambling preferences and occupational fraud within the framework of the fraud triangle theory, emphasizing the 'pressure' element. To explore this relationship, the research employed several methods, including reliability and validity tests, correlation analysis, and regression analysis, to strengthen the survey research. The findings indicate that individuals with stronger gambling preferences are more likely to engage in occupational fraud. This relationship is mediated by ego depletion and moderated by psychological capital and superstitious beliefs, which align with theoretical models of cognitive biases. Further analysis reveals that psychological capital and superstitious beliefs play a moderating role through the mediating effect pathway from gambling preferences to ego depletion. The study provides valuable insights for developing effective fraud prevention strategies in corporate governance.

The research on the intervention of open-skill exercise on the executive functions of children and adolescents still requires quantitative synthesis, and there is inconsistency in the effects of intervention by strategic and interceptive skills, which are sub-divided from open-skill exercise. Therefore, this study systematically explores the aforementioned issues and examines the potential moderating factors in the effects of open-skill exercise intervention on executive functions.

Computer searches of the CNKI, WOS, PubMed, ScienceDirect and SPORTDiscus databases were conducted. Two researchers independently screened the articles and extracted data, and used the bias risk assessment tool recommended by the Cochrane Collaboration Network and the Methodological Index for Non- Randomized Studies (MINORS) scale to assess included randomized controlled trials (RCTs) and quasi-experimental designs (QEDs). Statistical analyses were performed using Stata 16.0 software.

A total of 16 articles and 17 studies were included, comprising 11 RCTs and 6 QEDs. The participants were 1,298 children and adolescents aged 5 to 16. Open skill exercises have significant intervention effects (p < 0.01) on inhibitory control (SMD = -0.627, 95%CI = -0.890 to -0.363), working memory (SMD = -0.517, 95%CI = -0.768 to -0.266), and cognitive flexibility (SMD = -0.652, 95%CI = -1.085 to -0.219). The effects of strategic skill exercises are higher than those of interceptive skills, particularly in the dimension of inhibitory control (SMD = -0.707, 95%CI = -0.819 to -0.594, p < 0.05). In addition, moderate-intensity and higher-frequency exercises overall have a more positive effect on promoting executive functions (p < 0.05); interventions of 6 to 10 weeks are more effective for working memory (p < 0.05), while 30-min sessions are the most effective for working memory (p < 0.05), and sessions lasting 75 to 120 min are the most effective for cognitive flexibility (p < 0.05). Open-skill exercise has a more positive impact on inhibitory control in the 5-9 age group and on working memory in the 10-16 age group (p < 0.05); open-skill exercise, especially, has a more positive intervention effect on inhibitory control in the Eastern group (p < 0.05). Both Egger linear regression analyses and literature sensitivity analyses suggested that the Meta-analysis results were stable and reliable.

Open-skill exercise has a positive intervention effect on executive functioning in children and adolescents, and strategic skill exercise interventions are more effective. In addition, the quantitative elements of exercise (intensity, frequency, and duration per session) and demographic factors (age and ethnicity) play a potential moderating role in this context. Based on this, it is recommended that children and adolescents choose more strategic open-skill exercises according to their actual situation and select appropriate quantitative exercise factors to maximize the enhancement of their executive functions.

Converging lines of research indicate that inhibitory control is likely to be compromised in contexts that place competing demands on emotional, motivational, and cognitive systems, potentially leading to damaging impulsive behavior. The objective of this study was to identify the neural impact of three challenging contexts that typically compromise self-regulation and weaken impulse control. Participants included 66 healthy adults (M/SDage = 29.82/10.21 years old, 63.6% female) who were free of psychiatric disorders and psychotropic medication use. Participants completed a set of novel Go/NoGo (GNG) paradigms in the scanner, which manipulated contextual factors to induce (i) aversive emotions, (ii) appetitive drive, or (iii) concurrent working memory load. Voxelwise analysis of neural activation during each of these tasks was compared to that of a neutral GNG task. Findings revealed differential inhibition-related activation in the aversive emotions and appetitive drive GNG tasks relative to the neutral task in frontal, parietal and temporal cortices, suggesting emotional and motivational contexts may suppress activation of these cortical regions during inhibitory control. In contrast, the GNG task with a concurrent working memory load showed widespread increased activation across the cortex compared to the neutral task, indicative of enhanced recruitment of executive control regions. Results suggest the neural circuitry recruited for inhibitory control varies depending on the concomitant emotional, motivational, and cognitive demands of a given context. This battery of GNG tasks can be used by researchers interested in studying unique patterns of neural activation associated with inhibitory control across three clinically relevant contexts that challenge self-regulation and confer risk for impulsive behavior.

Obesity is an increasing medical issue not responding well to behavioural treatments beyond their initial weeks/months.

Before suggesting surgical or pharmacological interventions, medical professionals might consider referrals to cost-effective, community-based behavioural treatments if stronger theoretical/empirical bases were demonstrated. Thus, evaluation of such is warranted.

Women with obesity were randomly assigned to 6-month treatments emphasizing either behavioural theory-based methods focused on exercise-associated psychological changes generalizing to dietary changes (n = 101), or typical instruction in weight-control methods (n = 53). Theory-driven psychosocial, behavioural and weight changes were assessed over 12 months.

Improvements in all measured variables were significantly greater in the behavioural theory group. In the evaluation of hypothesized theory-based relationships-which have overarching bases in social cognitive theory-(1) self-efficacy theory was supported by self-regulation-associated increases in self-efficacy predicting later positive changes in exercise and the diet; (2) coaction theory was reinforced by the identified transfer of changes in self-regulation of exercise to self-regulation of eating; (3) the mood-behaviour model was sustained by improved mood predicting exercise and dietary improvements through (mediated by) self-regulation changes; (4) self-regulation theory was bolstered through early improvements in self-regulation supporting its longer-term increase, especially under conditions of self-regulatory skills practice and (5) operant conditioning theory was supported through results indicating a reinforcing effect from exercise-associated mood improvement to reduced emotional eating. Across the theories, relationships among tested variables were generally stronger in the behavioural theory group. Improvements in exercise and dietary behaviours were significant independent predictors of reduced weight.

Findings support the addressed behavioural theories within a community-based obesity treatment model that emphasized exercise for its psychosocial impacts on dietary behaviours and sustained weight loss. Based on the present empirical supports, medical professionals should consider referral to such approaches before (or in combination with) surgical or pharmacological methods.

Fear of missing out (FoMO) is a new type of anxiety disorder in the context of the Internet, which has a negative effects on the physical and mental health and behavior of college students, such as Internet addiction, non-adaptive socializing, and negative emotions. In order to investigate the effect of relative deprivation (RD) on FoMO of college students, this study conducted a moderated mediation model to examine the relationship between RD, FoMO, self-regulatory fatigue (SRF), and personal belief in a just world (BJW).

A total of 956 college students were surveyed on a RD Questionnaire, SRF Scale, FoMO Scale, and Personal BJW Scale.

The results showed as follows: (1) College students' RD positively predicted FoMO and SRF. (2) SRF partially mediated the link between RD and FoMO. (3) Personal BJW moderated the relationship between RD and FoMO, that is, when personal BJW is high, RD has a stronger predictive effect on SRF.

The results of this study help to reveal the influence and mechanism of RD of college students on FoMO. The results also show that reducing college students' RD, improving self-control ability, and cultivating rational personal BJW can effectively prevent FoMO.

The purpose of this study was to use the advanced technique of Network Intervention Analysis (NIA) to investigate the trajectory of symptom change associated with the effects of self-control training on youth university students' chronic ego depletion aftereffects.

The nine nodes of chronic ego depletion aftereffects and integrated self-control training were taken as nodes in the network and analyzed using NIA. Networks were computed at the baseline, at the end of treatment, at 1-, 3-, 6-, 9- and 12-month follow up. 62 samples were recruited from universities and randomly divided into two groups. The sample ranged in age from 18 to 25 years and included both males and females.

Self-control training interventions directly improved the states of low self-efficacy, low adherence, and work burnout, as well as indirectly alleviated fatigue, emotional regulation disorders, and other issues. Follow-up surveys showed that the intervention not only had immediate effects but also had long-term effects.

These findings indicate that self-control training has a direct intervention effect on low self-efficacy, low adherence, and work burnout of youth university students' ego depletion aftereffects. This study is the first application of NIA in abnormal psychological state intervention research outside the field of mental disorder treatment. NIA is a promising method to evaluate the trajectories of intervention change and the direct and indirect effects of training interventions.

The concept of cognitive reserve (CR) has been a cornerstone in cognitive aging research, offering a framework to explain how life experiences like education, occupation, bilingualism, and physical exercise may buffer individuals from cognitive decline in the face of aging or neurological disease. However, this paper argues that the CR model, while influential, may have outlived its usefulness due to inherent limitations that constrain future research directions and unintentionally encourage "magical thinking". Specifically, CR's definition, which relies on cognitive performance being "better than expected" based on known measures of brain structure and function, makes the concept temporally bound to current scientific understanding, potentially stifling novel insights into cognition. In contrast, we propose a shift to a cognitive capacity (CC) framework, which views cognitive performance as being always determined by the brain's structural and functional capacities, without needing to invoke expectations based on incomplete knowledge. The CC framework is broader, encompassing factors that either promote or demote cognitive performance by directly modifying brain structure and function. This reconceptualization opens avenues for investigating cognitive enhancement not only in the context of aging or disease but also in young, healthy individuals. By emphasizing causal pathways between brain changes and cognitive outcomes, this perspective provides a more flexible and testable approach to understanding the mechanisms behind cognitive performance and its modulation across the lifespan.

The deleterious consequences of mental fatigue (MF) on athletes in diverse sporting domains have been subject to extensive inquiry. However, the efficacy of interventions to counteract the effects of MF remains largely elusive. This review aims to evaluate the effects of counteractive interventions on the sport-specific performance of mentally fatigued athletes. Moreover, synthesizes the current evidence on which sports effectively counter the detrimental effects of MF with interventions, highlighting potential avenues for upcoming research. A systematic search was executed via Web of Science, Scopus, PubMed, and EBSCOhost, in addition to Google Scholar and references for grey literature. A meta-analysis was executed to compute effect sizes for different interventions with 13 qualified papers. Interventions include transcranial direct current stimulation, person-fit, mindfulness, glucose supplementation, caffeine mouth rinsing, and nature exposure showed potential to mitigate the detrimental effects on sport-specific performance, particularly in shooting accuracy (ES = 0.591; p = 0.001), decision-making accuracy (ES = 0.553; p = 0.006), and reaction time (ES = -0.871; p < 0.001), however, not in completion time (ES = -0.302; p = 0.182). This review underscores the unique roles of self-regulatory resources and directed attention. Nonetheless, a cautious interpretation of the findings is warranted given the paucity of investigations involving potential interventions in numerous other sports, such as volleyball, Australian football, cricket, and boxing.

Ego depletion theory proposes that self-regulation depends on a limited energy resource (willpower). The simple initial theory has been refined to emphasize conservation rather than resource exhaustion, extended to encompass decision making, planning, and initiative, and linked to physical bodily energy (glucose). Recent challenges offered alternative explanations (which have largely failed) and questioned replicability (which has now been well established). Methods have improved, particularly with emphasis on longer, stronger manipulations to ensure fatigue. New work extends ego depletion into workplace settings and sports. Interpersonal conflict may be both a major cause and consequence. New questions include the possibility of chronic ego depletion (e.g., in burnout), protective factors and coping strategies, individual differences, and recovery processes.

Fairness-related decision-making often involves a conflict between egoistic and prosocial motives. Previous research based on Terror Management Theory (TMT) indicates that mortality salience can promote both selfish and prosocial behaviors, leaving its effect on fairness-related decision-making uncertain. This study integrates TMT with the strength model of self-control to investigate the effects of mortality salience on fairness-related decision-making and to examine the moderating role of dispositional self-control. Participants were primed with either mortality salience or negative affect and then asked to make a series of binary choices (equal allocation vs. unequal allocation favoring themselves) to distribute monetary resources. In both studies, mortality salience heightened selfish tendencies, leading to less equitable monetary allocation. Study 2 further revealed that this effect occurred among participants with low, but not high, self-control. These findings indicate that mortality salience promotes selfishness and inequitable monetary allocation, but that self-control can buffer these effects.

Drawing on the "kicking the barking dog effect", this study investigated the individual and group-level mechanisms underlying triggered displaced aggression (TDA).

Three experiments were conducted to investigate the effects of anger and hostile attribution on TDA, examining these factors at both the individual and group levels. The preliminary experiment investigated how emotions affect subsequent cognition at an individual level with the aim of understanding the underlying generative process of TDA. Experiment 1 explored the relationship between anger, hostile attribution, and subsequent aggressive behaviors at an individual level, while also discussing the underlying generative process of TDA. Experiment 2 investigated the relationship between anger, hostile attribution, and subsequent aggressive behaviors from a group-level perspective, while also delving into the impact of trigger identity on the underlying generative process of TDA.

When individuals were exposed to both a provocation and a subsequent triggering situation, they demonstrated stronger hostile attribution and displayed more aggressive behavior directed toward the trigger. This study found that hostile attribution played a complete mediating role in the influence of anger on TDA, while the triggering situation itself had a moderating role. In the presence of triggering situations, individuals exhibited stronger hostile attribution as their level of anger increased. In the absence of a triggering situation, changes in anger level did not have a significant effect. In the presence of a triggering situation, the identity of the trigger played a moderating role in the process of "anger → hostile attribution → TDA". When the trigger belonged to an in-group, individuals exhibited stronger hostile attribution toward the out-group and subsequently displayed greater TDA.

These findings expand the applicability of the "kicking the barking dog effect" and offer suggestions for controlling the escalation of intergroup conflicts.

Evidence suggests that complex micro-dynamics occurring in daily life underly the development of mental distress. We aimed to (1) study the cross-lagged association between stressful events and negative affect (NA), (2) show that there is substantial between-person variability in idiographic associations and (3) show that idiographic associations are indicative of mental health. Experience sampling study assessing perceived stressfulness of events (PSE) and NA four times per day for 2 weeks in a non-clinical convenience sample (N = 70, mean age = 22.9, 61% female, 69% German). Bivariate vector autoregressive model implemented in dynamic structural equation modelling to model the associations between stressful events and NA and obtain idiographic associations. Stressfulness of events and NA were significantly reciprocally associated. Autocorrelations and cross-lagged associations from PSE to NA showed substantial variability and were significantly related with trait measures of depression, anxiety, well-being, and perceived stress. Contrary to expectations, cross-lagged associations from NA to stressfulness of events were not related to trait mental health. The approach outlined in this article is useful for studying idiographic dynamics in daily life. The findings increase our understanding of micro-dynamics underlying mental health and individual differences in these processes.

The current study investigated the effects of ego-depletion in junior high school students on displaced aggressive behavior and the counteraction of the nature. Study 1 investigated the effects of ego-depletion on displaced aggressive behavior in junior high school students using a within-subject design, comparing the differences in displaced aggressive behavior between the induced ego-depletion condition and the non-induced ego-depletion condition. Results showed that junior high school students exhibited significantly higher levels of displaced aggressive behavior under the induced ego-depletion condition compared to the non-induced ego-depletion condition. Study 2 examined the role of the nature in the process of ego-depletion influencing displaced aggressive behavior. A 2 (ego-depletion: induced ego-depletion vs. non-induced ego-depletion) × 2 (picture type: blank picture vs. natural picture) mixed design was used. A picture-viewing task was inserted between the ego-depletion task and the displaced aggressive behavior task to compare the differences in displaced aggressive behavior between the group that viewed blank pictures and the group that viewed natural pictures. The results showed that under the induced ego-depletion condition, there was no significant difference in displaced aggressive behavior between viewing natural pictures and viewing blank pictures. However, after viewing blank pictures, displaced aggressive behavior under induced ego-depletion condition was significantly higher than under non-induced ego-depletion condition; after viewing natural pictures, there was no significant difference in displaced aggressive behavior between induced ego-depletion condition and non-induced ego-depletion condition. These results suggest that ego-depletion can increase displaced aggressive behavior in junior high school students, but this phenomenon is not observed after exposure to nature. The current study provides empirical evidence for investigating the effects of ego-depletion on displaced aggressive behavior.

This study aimed to assess the plausibility of self-control depletion, or ego-depletion, as the underlying cognitive resource responsible for performance decrements on the sustained attention to response task.

Researchers suggested that self-control is a limited cognitive resource used to complete a myriad of processes, including sustained attention. Past research showed that trait self-control affects some sustained attention tasks. However, little research has investigated the effect of self-control as a limited cognitive resource that varies over time (i.e., as a state-dependent variable).

This experiment investigated the effect of self-control (trait and state) on a sustained motor-inhibition task (e.g., sustained attention to response task; SART). State self-control was manipulated using a between-subjects design-participants in the experimental condition completed a task designed to deplete state self-control prior to performing the SART while the control condition completed a modified version that did not deplete self-control.

Trait self-control predicted performance on the SART, but the depletion task (state self-control) had no detectable effect.

Given the evidence, it is unlikely that state self-control plays a causal role in performance decrements in the SART, but there appears to be some association between performance on the SART and trait self-control.

Trait self-control ought to be considered in future work for personnel selection in real-world tasks that the SART models such as long-distance driving, air traffic control, and TSA operations.

Sleep quality significantly impacts employees' attitudes and behaviors. Using ego depletion theory, we examined the influence of sleep quality on work engagement and creative behavior, also investigating gender differences in these effects.

A multi-wave survey approach was employed with a six-week interval between waves for data collection. Participants were recruited online across two waves, totaling 322 employees from the United Kingdom and the United States.

Regression analyses revealed a statistically significant positive relationship between sleep quality and creative behavior, mediated by work engagement. Additionally, gender moderated both the direct and indirect effects of sleep quality.

The study found a positive relationship between sleep quality and creative behavior, mediated by work engagement, with notable gender differences. Sleep quality had a stronger impact on work engagement for men than women, and a stronger indirect effect on creative behavior through work engagement. These findings add to the existing literature on the influence of sleep quality on creative behavior.

The goal of this study is to learn more about social media ostracism, a stressor associated with online social networks, defined by feelings of rejection, exclusion, or ignoring. We investigate the connection between social media ostracism and worker creativity. We suggest that psychological safety and psychological rumination serve as intermediaries in this relationship. Furthermore, we investigate emotional intelligence as a relationship regulator. To verify our hypothesis, we gathered data with the help of the HR department from 244 workers of nine Chinese organizations. Our research shows that psychological rumination and social media exclusion are significantly correlated, but only in workers with low emotional intelligence. Furthermore, for individuals with strong emotional intelligence, we did not discover a statistically negative association between psychological safety and social media exclusion. Findings suggest that psychological safety and psychological rumination serve as mediating factors in the relationship between employee creativity and social media exclusion. This study illuminates the negative aspects of social media ostracism and reveals how it might hinder creativity. It also emphasizes how emotional intelligence functions as a moderator. Organizations may learn a lot from this study on how to lessen the negative impacts of social media exclusion on employee creativity.

Given that mother plays the main nurturing role in a family unit and their unique influence on children's development, the current study aimed to examine the influence of maternal phubbing on children's problematic media use and the independent and interactive moderating role of children's negative affectivity and effortful control.

Participants were 1986 children aged 3 to 6 years in Shanghai, China. Their mothers were asked to complete a series of questionnaires including parental phubbing scale, problematic media use measure, and child behavior questionnaire. To investigate the moderating influence of children's negative affectivity and effortful control, hierarchical linear regression analyses were conducted using SPSS 24.0. Simple slopes analyses and the Johnson-Neyman technique were further used to depict moderation effects.

Maternal phubbing was associated with higher levels of problematic media use in preschool children (β = 0.18, p <.001, [0.14, 0.22]). Children's negative affectivity acts as a risk factor, exacerbating the adverse effects of maternal phubbing on children's problematic media use (β = 0.05, t = 2.69, p < 0.05), whereas children's effortful control acts as a protective factor, buffering the link between maternal phubbing and children's problematic media use (β = -0.10, t = -5.00, p < 0.001).

These results suggest that interventions seeking to promote appropriate digital development in preschoolers should take the child's temperament into account and be complemented by active parental mediation and involvement.

Mental fatigue impairs performance across several sports domains. However, a systematic review on its effects on racket sports performance has been lacking due to the previous scarcity of studies. This review aims to provide a comprehensive review the effects of mental fatigue on racket players' performance, with a discussion of the underlying mechanisms. A thorough search was conducted across five databases, including Web of Science, PubMed, SCOPUS, SPORTDiscus (via EBSCOhost), and the Psychological and Behavioral Science Collection (via EBSCOhost). The PICOS framework established the inclusion criteria: (1) healthy racket sports players; (2) induction of mental fatigue in both field and laboratory settings; (3) comparison of mental fatigue interventions with a control group (e.g., watching a movie or reading a magazine); (4) assessment of performance outcomes, including physical performance, skilled performance, and perceptual-cognitive performance; and (5) randomized controlled trials (RCTs), non-randomized controlled trials (non-RCTs), and non-randomized non-controlled trials. Mental fatigue manipulation, subjective evaluation, and (neuro)physiological markers were synthesized to support the successful induction of mental fatigue. Performance was categorized into tennis, table tennis, badminton, and padel based on the characteristics of specific racket sports domains. Secondary outcomes, such as the rate perception of effort (RPE) and motivation, were synthesized to explain the mechanisms based on the prominent theory of the Psychobiological model of endurance performance. Six studies revealed that mental fatigue impacts stroke performance in table tennis, affecting speed, accuracy, faults, and only second-serve accuracy in tennis. The response time of psychomotor performance increased in table tennis, padel, and badminton. Meanwhile, mental fatigue increased the RPE and remained unchanged in heart rate, blood glucose, and lactate, consistent with the Psychobiological model of endurance performance. Additionally, attention is suggested as a significant underlying psychobiological factor.

The relationship between a performer's conscious involvement or investment in movement control and monitoring and the ability to inhibit the movement is still unclear. We conducted three experiments to investigate whether a higher inclination for conscious movement investment benefits the inhibition of a simple keypress response. In all experiments, the inclination for conscious movement investment was measured with the Movement-Specific Reinvestment Scale. In Experiment 1, participants performed the go/no-go task and conscious investment was manipulated by directing conscious attention either to the finger movement (i.e., internal focus) or to the resulting motion of the key (i.e., external focus). The results showed that neither the participants' inclination for conscious movement investment, nor the direction of conscious attention affected inhibition performance. In Experiment 2, participants performed the stop-signal task, which is more attention demanding than the go/no-go task. The results showed that participants with a high or low inclination for conscious movement investment did not differ in inhibition performance. In Experiment 3 an ego-depletion procedure was included that limits resources for conscious movement investment. Before and after this ego-depletion procedure, participants performed the stop-signal task. The results showed that participants with a high inclination for conscious movement investment slowed down inhibition when they felt mentally depleted, while no slowing down of inhibition was found among participants who felt less depleted and/or had a low inclination for conscious movement investment. Together, the study provides evidence that increased conscious movement investment is beneficial for movement inhibition. Yet, these effects only emerge against the dynamic background of interacting individual (e.g., inclination for conscious movement investment, available attentional resources) and task constraints (e.g., task difficulty).

The resource depletion model proposes that self-control is a limited resource that may become depleted after repeated use. This study aimed to improve our understanding of the correlates of resource depletion in parents, examine the association between resource depletion and use of coercive food parenting practices, and explore the relationship between resource depletion and stress. Children aged 5-9 and their parents (n = 631 dyads) were recruited from primary care clinics in a large metropolitan area in the United States in 2016-2019. Ecological momentary assessment was carried out over seven days with parents. Frequency tabulations and descriptive statistics were calculated to examine the overall, between-participant, and within-participant frequency of resource depletion, stress, and coercive food parenting practices. Resource depletion was higher among mothers (as compared to fathers) and native born participants (as compared to immigrants). Resource depletion was found to decrease significantly with each increase in household income level and perceived co-parenting support was negatively associated with resource depletion. Greater resource depletion earlier in the day was positively associated with coercive food parenting practices (e.g., food restriction, pressure-to-eat) at dinner the same night. Further, prior day resource depletion was associated with greater pressure-to-eat the next day. Parents with lower chronic stress were found to engage in pressuring when experiencing higher depletion. Clinicians and public health professionals should be aware of the role the resource depletion can play in parent's use of specific food parenting practices and seek to provide parents with the support they need to manage the cognitive load they are experiencing.

The issue of academic procrastination is highly prevalent among university students. It not only has a deterimental effect on students' academic performance but also poses a risk to their physical and mental well-being. Anxiety, as a negative emotion, has attracted researchers' attention in relation to academic procrastination. Research indicates a correlation between state anxiety and academic procrastination, but the underlying mechanisms that drive this association remain unclear. When individuals experience ego-depletion, it can lead to psychological exhaustion, subsequently leading to procrastination. Gender role conceptions, shaped by sociocultural and psychological mechanisms, have profound implications on individuals' cognition, emotions, and behaviors. This study primarily aims to explore the relationship between state anxiety and academic procrastination among university students, with a particularly focus on the mediating role of ego-depletion and the moderating role of gender. A survey using the State Anxiety Scale, Ego-Depletion Scale, and Irrational Procrastination Scale was administered to 3370 undergraduates. State anxiety shows positive correlations with ego depletion and academic procrastination (r = 0.665, p < 0.01; r = 0.491, p < 0.01), while ego depletion is also positively linked to academic procrastination (r = 0.500, p < 0.01). State anxiety serves as a positive predictor of academic procrastination, with a confidence interval of 95% [0.626, 0.696]; additionally, ego depletion partially mediates the relationship between state anxiety and academic procrastination, with a confidence interval of 95% [0.168, 0.251]. Gender acts as a moderator in directly predicting the impact of state anxiety on academic procrastination and in the latter stage of mediating the effect of ego depletion. State anxiety can significantly and positively predict academic procrastination among university students. Ego-depletion partially mediates the relationship between state anxiety and academic procrastination. The direct predictive effect of state anxiety on academic procrastination, as well as the mediating role of ego-depletion, is moderated by gender. This provides educators and university students themselves with reference for addressing the issue of academic procrastination.

Many concepts describe how individuals sustain effort despite challenging circumstances. For example, scholars and practitioners may incorporate discussions of grit, hardiness, self-control, and resilience into their ideas of performance under adversity. Although there are nuanced points underlying each construct capable of generating empirically sound propositions, the shared attributes make them difficult to differentiate. As a result, substantial confusion arises when debating how these related factors concomitantly contribute to success, especially when practitioners attempt to communicate these ideas in applied settings. The model proposed here-psychological endurance-is a unified theory to explore how multiple concepts contribute to sustained goal-directed behaviors and individual success. Central to this model is the metaphor of a psychological battery, which potentiates and sustains optimal performance despite adversity. Grit and hardiness are associated with the maximum charge of the psychological battery, or how long an individual could sustain effort. Self-control modulates energy management that augments effort required to sustain endurance, whereas resilience represents the ability to recharge. These factors are constrained by both psychological and physiological stressors in the environment that drain the psychology battery. Taken together, these ideas form a novel framework to discuss related psychological concepts, and ideally, optimize intervention to enhance psychological endurance.

Creatine supplementation has been put forward as a possible aid to cognition, particularly for vegans, vegetarians, the elderly, sleep deprived and hypoxic individuals. However, previous narrative reviews have only provided limited support for these claims. This is despite the fact that research has shown that creatine supplementation can induce increased brain concentrations of creatine, albeit to a limited extent. We carried out a systematic review to examine the current state of affairs. The review supported claims that creatine supplementation can increases brain creatine content but also demonstrated somewhat equivocal results for effects on cognition. It does, however, provide evidence to suggest that more research is required with stressed populations, as supplementation does appear to significantly affect brain content. Issues with research design, especially supplementation regimens, need to be addressed. Future research must include measurements of creatine brain content.

Various perspectives on the existence and degree of motivation, which is a crucial factor influencing human behavior, have been studied for many years. Especially in adolescence, a phase marked by rapid change, motivation plays a crucial role in supporting young people to achieve their goals, fulfill their responsibilities, and experience healthy development.

The present study aims to investigate the structural relationships among perceived parental autonomy support, satisfaction of psychological needs, self-control, and academic motivation.

The study was conducted with a total of 427 high school students, including 230 females and 197 males, aged between 14 and 19 (M = 15.82; SD = 1.02).

Participants completed self-report measures of academic motivation, parental autonomy support, psychological needs satisfaction, and self-control. Structural equation modeling was performed to explore complex relationships between variables of interest.

The study revealed that psychological needs satisfaction increased as parental autonomy support increased, and self-control also increased with the satisfaction of psychological needs. It was also found that satisfaction of psychological needs was positively related to both intrinsic and extrinsic motivation. Additionally, self-control was associated with increased intrinsic motivation and decreased amotivation. In addition, it was found that parental autonomy support has an indirect relationship with academic motivation through the satisfaction of psychological needs and self-control.

It is believed that these connections will lead to a deeper understanding of the significant processes in adolescence and serve as a foundation for developing and implementing psycho-educational interventions related to these variables.

Greene's influential dual-process model of moral cognition (mDPM) proposes that when people engage in Type 2 processing, they tend to make consequentialist moral judgments. One important source of empirical support for this claim comes from studies that ask participants to make moral judgments while experimentally manipulating Type 2 processing. This paper presents a meta-analysis of the published psychological literature on the effect of four standard cognitive-processing manipulations (cognitive load; ego depletion; induction; time restriction) on moral judgments about sacrificial moral dilemmas [n = 44; k = 68; total N = 14, 003; M(N) = 194.5]. The overall pooled effect was in the direction predicted by the mDPM, but did not reach statistical significance. Restricting the dataset to effect sizes from (high-conflict) personal sacrificial dilemmas (a type of sacrificial dilemma that is often argued to be best suited for tests of the mDPM) also did not yield a significant pooled effect. The same was true for a meta-analysis of the subset of studies that allowed for analysis using the process dissociation approach [n = 8; k = 12; total N = 2, 577; M(N) = 214.8]. I argue that these results undermine one important line of evidence for the mDPM and discuss a series of potential objections against this conclusion.

To understand the current status of self-regulatory fatigue among gynecologic cancer chemotherapy patients and explore influencing factors.

Using convenient sampling, a total of 232 gynecological cancer chemotherapy patients from two tertiary hospitals in Zhengzhou, Henan, China, were selected as study subjects from February 2023 to April 2023. General information questionnaire, Self-Regulatory Fatigue Scale (SRF-S), Strategies Used by People to Promote Health (SUPPH) Scale, Connor-Davidson resilience scale (CD-RISC) and Perceived Social Support Scale (PSSS) were employed for data collection. The data were analyzed using SPSS 26.0 software. Chi-square test and binary logistic regression were executed to explore the correlates of self-regulatory fatigue, the significance level (α) was set at 0.05.

The self-regulatory fatigue score of the 232 patients was 44 (36, 56). Binary logistic regression analyses revealed significant associations, demonstrating that residing in urban areas (OR=0.241, P=0.015), having no comorbidities (OR=0.158, P=0.015), increased perceived social support (OR=0.937, P=0.001), strong self-efficacy (OR=0.959, P=0.021), and heightened psychological resilience (OR=0.895, P<0.001) acted as protective factors against self-regulatory fatigue (P < 0.05).

Patients residing in rural areas, having more than two comorbidities, lower self-efficacy and psychological resilience levels, and lower perceived social support are indicative of higher levels of self-regulatory fatigue. Identifying these influencing factors can provide references and support for developing individualized support and intervention measures to improve patients' physical and mental well-being.

In this study, we examine how leaders' emotional labour strategies (surface acting and deep acting) deplete leaders' self-control resources to predict abusive supervision, in addition to the moderating role of leader mindfulness. Integrating ego-depletion theory and emotion regulation theory, we hypothesise that deep acting and surface acting predict higher levels of abusive supervision, which is mediated by reduced self-control. Furthermore, we predict that leaders' trait mindfulness moderates the relationship between emotional labour and self-control on abusive supervision. Results from a three-wave study of leader-follower dyads supported mediation hypotheses; both deep and surface acting predicted abusive supervision, which is mediated by reduced self-control. Our moderated mediation hypotheses were supported for deep acting but not surface acting. This research contributes to the literature by demonstrating the depleting nature of emotional labour in leadership and the importance of leader mindfulness as a boundary condition that can make deep acting less harmful for leader behaviour.

It has been demonstrated in previous studies that prolonged mental effort exertion evokes mental fatigue and leads to impairments in task performance. In the current investigation, we aimed to test the hypothesis that mental fatigue depends on motivational processes and can be influenced by task valuation. In two studies, we experimentally manipulated the value of the task by financial rewards (Study 1) and the sense of autonomy (Study 2). Contrary to our predictions, those manipulations did not influence the main dependent variables. We also introduced additional rewards after prolonged effort exertion. In line with our expectations, the results showed that mental fatigue increases with time spent on effortful tasks. Importantly, however, mental fatigue decreases when the value of the task rises. This effect is accompanied by stronger effort engagement and improvement in task performance. The findings support the motivational theories of mental effort and fatigue, showing that mental fatigue might serve as a signal of diminishing value of the ongoing task.

People are more likely to perform poorly on a self-control task following a previous task requiring self-control (ego-depletion), but the mechanism for this effect remains unclear. We used pupillometry to test the role of attentional effort in ego-depletion. We hypothesized that an elevated pupil diameter (PD)-a common physiological measure of effort-during an initial task requiring self-control should be negatively associated with performance on a subsequent control task. To test this hypothesis, participants were first assigned to either a high- or low-demand attention task (manipulation; a standard ego-depletion paradigm), after which all participants completed the same Stroop task. We then separately extracted both sustained (low-frequency) and phasic (high-frequency) changes in PD from both tasks to evaluate possible associations with lapses of cognitive control on the Stroop task. We first show that in the initial task, sustained PD was larger among participants who were assigned to the demanding attention condition. Furthermore, ego-depletion effects were serially mediated by PD: an elevated PD response emerged rapidly among the experimental group during the manipulation, persisted as an elevated baseline response during the Stroop task, and predicted worse accuracy on incongruent trials, revealing a potential indirect pathway to ego-depletion via sustained attention. Secondary analyses revealed another, independent and direct pathway via high levels of transient attentional control: participants who exhibited large phasic responses during the manipulation tended to perform worse on the subsequent Stroop task. We conclude by exploring the neuroscientific implications of these results within the context of current theories of self-control.

This study examined the relationship between loneliness and bedtime procrastination among Chinese university students, the mediating effects of COVID-19 risk perception and self-regulatory fatigue, and connectedness to nature's protective role, post pandemic.

We recruited 855 students to complete the Loneliness, Perceived Risk of COVID-19 Pandemic, Self-Regulatory Fatigue, Bedtime Procrastination, and Connectedness to Nature Scales. Data for descriptive statistics, correlation analysis, and moderated chain mediation effects were analyzed using SPSS 24.0 and process 3.5 macros.

Loneliness positively correlated with bedtime procrastination, COVID-19 risk perception mediated the impact of loneliness on bedtime procrastination, self-regulatory fatigue mediated the effect of loneliness on bedtime procrastination, and COVID-19 risk perception and self-regulatory fatigue mediated the effect between loneliness and bedtime procrastination. Furthermore, connectedness to nature mediated the impact of COVID-19 risk perception on self-regulatory fatigue.

The results indicate the effects and potential mechanisms of loneliness on bedtime procrastination after the relaxation of the pandemic prevention and control policy in China from the perspective of self-regulatory resources and provide insights into improving university students' sleep routine and mental health post pandemic.

The deleterious effects of mental fatigue (MF) on athletes have been carefully studied in various sports, such as soccer, badminton, and swimming. Even though many researchers have sought ways to ameliorate the negative impact of MF, there is still a lack of studies that review the interventions used to counteract MF among athletes. This review aims to report the current evidence exploring the effects of interventions on MF and sport-specific performance, including sport-specific motor performance and perceptual-cognitive skills. Web of Science, Scopus, PubMed, and SPORTDicus (EBSCOhost) were combed through to find relevant publications. Additionally, the references and Google Scholar were searched for any grey literature. For the current review, we included only randomized controlled trials that involved athletes, a primary task to induce MF, interventions to counter MF with comparable protocols, and the outcomes of sport-specific motor performance and perceptual-cognitive skill. The selection criteria resulted in the inclusion of 10 articles. The manipulations of autonomous self-control exertion, person-fit, nature exposure, mindfulness, and transactional direct current stimulation showed that positive interventions counteract MF and improve sport-specific performance in different domains, including strength, speed, skill, stamina, and perceptual-cognitive skills. The selected interventions could significantly counteract MF and improve subsequent sport-specific performance. Moreover, self-regulation and attention resources showed the importance of the potential mechanisms behind the relevant interventions.

The aims of this study were to explore the predictive relationship between sleep quality and sense of coherence (SOC) and to examine a possible moderating role of mastery in this relationship. A three-wave longitudinal design was employed using a sample of 304 older adults aged 55-87 years old. Cross-lagged panel analyses and moderating effect analyses showed that sleep quality can predict the levels of SOC 6 months later, whereas SOC cannot predict sleep quality 6 months later. In addition, mastery can moderate the effect of sleep quality on SOC. Specifically, the lagged effects of sleep quality on SOC in older adults who had low levels of mastery were stronger than in those who had high levels of mastery. Overall, these findings provide valuable insights for understanding the predictive relationship between sleep quality and SOC and emphasise the moderating role of mastery. Also, our results offer important implications for enhancing the SOC in older adults by improving sleep quality and mastery.

Understanding the neurobiological correlates of behavioral inhibition in patients with depression who committed violent offenses could contribute to the prediction and prevention of violence. The present study recruited 29 depressed patients with violent offenses (VD group), 27 depressed patients without violent behavior (NVD group), and 28 healthy controls (HC group) to complete a visual Go/NoGo task, during which their responses and electroencephalography were simultaneously recorded using an event-related potentiometer. The results showed that the VD group made more commission errors and responded more slowly relative to the NVD and HC groups. The P3 amplitude of the VD group was reduced in the frontal and central brain regions compared to the HC group and increased in the parietal regions compared to the NVD group. In comparison to Go stimuli, NoGo stimuli induced longer P3 latencies in frontal regions in both the VD and NVD groups; however, this difference was not statistically significant in the HC group. These results provide electrophysical evidence of behavioral inhibition deficits in patients with depression, especially in those with violent behaviors. The reduced P3 amplitude in the frontal-central regions, increased P3 amplitude in the parietal regions, and increased NoGo P3 latency may be potential electrophysiological features that can predict violent behavior in patients with depression.

The ambivalent experience of superior-subordinate relationships is widespread in organisations and has gradually become an important factor influencing employees to actively engage in extra-role behaviours. However, employees' constructive deviance is extremely important for organisational development as they are important extra-role behaviours for organisational innovation and change. Owing that academic research on the antecedents of employees' constructive extra-role behaviours has lacked attention to individual emotional variables such as the leader-member exchange ambivalence, by drawing on self-control resource theory and social cognitive theory, this study examined the effects of leader-member exchange ambivalence on employees' constructive deviance, as well as the role of ego depletion and role-breadth self-efficacy. Based on a two-point questionnaire survey of 332 employees from different industries in China, the study tested hypotheses with SPSS 27 and AMOS 27 and found that the more leader-member exchange ambivalence, the less likely they were to engage in employees' constructive deviance, leader-member exchange ambivalence affected employees' constructive deviance through ego depletion, and when role-breadth self-efficacy is high, the lower the ego depletion of employees with leader-member exchange ambivalence, the more likely they are to engage in employees' constructive deviance. This study is intended to guide organisations to pay attention to the problem of individual internal conflict arising from superior-subordinate relationships, to remove the barriers to constructive transgression by individuals, and to truly exploit the innovative capacity of individual organisations. The study suggests that managers should pay attention to the negative effects of employees' perceived ambivalent experiences of supervisor-subordinate relationships, maintain consistency, and build positive social exchange relationships with their employees. Organisations should strengthen the training of leaders and employees to eliminate the serious internal attrition that organisations face from social network relationships. And employees should face the limitations of resources and reduce dependence on the leader-member exchange relationship as the dependence for their work attitudes and behaviours.

Understanding affect as a determinant of physical activity has gained increased attention in health behavior research. Fluctuations in affect intensity from moment-to-moment (i.e., affective variability) may interfere with cognitive and regulatory processes, making it difficult to engage in goal-directed behaviors such as physical activity. Preliminary evidence indicates that those with greater trait-level affective variability engage in lower levels of habitual physical activity. However, the extent to which daily fluctuations in affect variability are associated with same-day physical activity levels is unknown. This study used ecological momentary assessment (EMA) to investigate day-level associations between affective variability (i.e., within-subject variance) and physical activity.

Young adults (N = 231, M = 23.58 ± 3.02 years) provided three months of smartphone-based EMA and smartwatch-based activity data. Every two weeks, participants completed a 4-day EMA measurement burst (M = 5.17 ± 1.28 bursts per participant). Bursts consisted of hourly randomly-prompted EMA surveys assessing momentary positive-activated (happy, energetic), positive-deactivated (relaxed), negative-activated (tense, stressed), and negative-deactivated (sad, fatigued) affect. Participants continuously wore a smartwatch to measure physical activity across the three months. Mixed-effects location scale modeling examined the day-level associations of affective variability (i.e., positive-activated, positive-deactivated, negative-activated, and negative-deactivated) and physical activity, controlling for covariates such as mean levels of affect, between-subject effects of physical activity, time of day, day of week, day in study, and smartwatch wear time.

There were 41,546 completed EMA surveys (M = 182.22 ± 69.82 per participant) included in the analyses. Above and beyond mean levels of affect, greater day-level variability in positive-activated affect was associated with greater physical activity on that same day compared to other days (τ = 0.01, p < .001), whereas greater day-level variability in negative-deactivated affect was associated with less physical activity on that same day compared to other days (τ = -0.01, p < .001). Day-level variability in positive-deactivated affect or negative-activated affect were not associated with day-level physical activity (ps > .05) CONCLUSIONS: Individuals were less active on days with greater variability in feeling sad and fatigued but more active on days with greater variability in feeling happy and energetic. Understanding the dynamic relationships of affective variability with day-level physical activity can strengthen physical activity interventions by considering how these processes differ within individuals and unfold within the context of daily life. Future research should examine causal pathways between affective variability and physical activity across the day.
