Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors that associated with people reported adopting public health behaviours (e.g., spatial distancing stricter hygiene) endorsed policy closing bars restaurants) the early stage of pandemic (April-May 2020). Respondents who...
Atheism and agnosticism are becoming increasingly popular, yet the neural processes underpinning individual differences in religious belief non-belief remain poorly understood. In current study, we examined between Believers Non-Believers with regard to fundamental resting networks using EEG microstate analysis. Results demonstrated that show increased contribution from a resting-state network associated deliberative or analytic processing (Microstate D), intuitive automatic C). Further,...
Self-control-the ability to inhibit inappropriate impulses-predicts economic, physical, and psychological well-being. However, recent findings demonstrate low correlations among self-control measures, raising the question of what actually is. Here, we examined idea that people high in show more stable mental processing, characterized by processing steps are fewer number but longer lasting because interruptions distracting impulses. To test this hypothesis, relied on resting...
Studies have consistently shown crowds contribute to home advantage in the National Basketball Association (NBA) by inspiring team effort, distracting opponents, and influencing referees. Quantifying effect of is challenging, however, due potential co-occurring drivers (e.g., travel, location familiarity). Our aim was isolate crowd using a "natural experiment" created Coronavirus disease 2019 (COVID-19) pandemic, which eliminated 53.4% 2020/2021 NBA regular season games (N = 1080). Using...
Abstract Though real-world decisions are often made in the shadow of economic uncertainties, work problems, relationship troubles, existential angst, etc., neural processes involved this common experience remain poorly understood. Here, we randomly assigned participants (N = 97) to either a poignant forecasted anxiety or no-anxiety control condition. Using electroencephalography (EEG), then examined how source-localized, anxiety-specific activation modulated risky decision making and...
Elite athletes are often required to travel across time zones for national and international competitions, causing frequent jet lag. The aim of this study was examine whether the direction travel-related lag is associated with performance in National Basketball Association (NBA), if so, explore potential mechanisms.
Summary Elite athletes are vulnerable to sleep and circadian disruption associated mental health symptoms. This study aimed investigate sex differences in sleep, rhythms, health, as well the moderating role of prediction among male professional female semi‐professional elite athletes. Participants were 87 Australian Rules football (ARF) (43% female; mean [standard deviation] age 24.0 [4.1] years). completed baseline questionnaires, 2 weeks sleep/wake monitoring via actigraphy, a phase...
Abstract Trait narcissism is characterized by significant heterogeneity across individuals. Despite advances in the conceptualization of narcissism, including increasing recognition that a multidimensional construct, sources this remain poorly understood. Here, we used neural trait approach to help better understand “how,” and shed light on “why,” individuals vary facets narcissism. Participants ( N = 58) first completed personality measures, Narcissistic Personality Inventory (NPI), then...

The present research aims isolate crowd utilizing a 'natural experiment' created Coronavirus disease 2019 (COVID-19) pandemic, which eliminated 577 1080 (53.4%) 2020/2021 NBA regular...
People display a high degree of heterogeneity in risk-taking behaviour, but this remains poorly understood. Here, we use neural trait approach to examine if task-independent, brain-based differences can help uncover the sources risky decision-making. We extend prior research two key ways. First, disentangled and strategic consistency using novel measures afforded by Balloon Analogue Risk Task. Second, applied personality neuroscience framework explore why traits are typically only weakly...
Anxiety impacts performance monitoring, though theory and past research are split on how for whom. However, has often examined either trait anxiety in isolation or task-dependent state indexed event-related potential components, such as the error-related negativity post-error positivity (Pe), calculated at a single node during limited window of time. We introduced 2 key novelties to this electroencephalography examine link between monitoring: (i) we manipulated antecedent, task-independent,...
Abstract Economic threat has far-reaching emotional and social consequences, yet the impact of economic on neurocognitive processes received little empirical scrutiny. Here, we examined causal relationship between conflict detection, a critical process in cognitive control associated with anterior cingulate cortex (ACC). Participants (N = 103) were first randomly assigned to read about gloomy forecast (Economic Threat condition) or stable (No-Threat Control condition). Notably, these...
Objectives: Mental fitness is increasingly considered a key component of an athlete’s competitive arsenal. Active domains mental include cognitive fitness, sleep, and health; these can differ between men women athletes. Our study investigated the associations gender to sleep health, interaction on in athletes during COVID-19 pandemic. Methods: 82 competing at levels from regional/state international (49% women, M -age = 23.3 years) completed measures self-control, intolerance uncertainty,...

Contributors to the literature on gamesmanship typically assume that can be clearly distinguished from other legal strategies used in sports. In this article, we argue is a mistake. Instead, propose form of strategic excellence and proper part competitive sport. Using Howe’s influential work as representation received view, show how current debate rests presupposition fails withstand critical scrutiny (Section 2). Further, once distinction shown untenable, evaluative account 3). By contrast,...
Psychological views on political orientation generally agree that conservatism is associated with negativity bias but disagree the form of association. Some view as a psychological defense insulates from negative stimuli and events. Others consequence increased dispositional sensitivity to Further complicating matters, research shows conservatives are sometimes more less sensitive The current integrates these opposing results. We reasoned should typically be if conservative beliefs act...
Experimental research and real-world events demonstrate a puzzling phenomenon—anxiety, which primarily inspires caution, sometimes precedes bouts of risk-taking. We conducted three studies to test whether this phenomenon is due the regulation anxiety via reactive approach motivation (RAM), leaves people less sensitive negative outcomes thus more likely take risks. In Study 1 ( N = 231), an achievement threat caused increased risk-taking on Behavioral Analogue Risk Task (BART) among trait...
Good sleep before and after competitions is crucial to cognitive, physiological performance recovery. Yet, elite athletes face a unique set of challenges when acquiring good competitions, indeed commonly report problems it matters most. This study examined the competition compared free days. A total 1808 nights actigraphy (n = 1495) diary 1335) data from Australian Football League National Rugby male (N 85, M-age 24.4 ± 3.6) were collected analysed using multi-level mixed models. On advanced...
Abstract Introduction Sleep and exercise are pillars of health. However, the temporal dynamics between these two behaviours remain poorly understood. This study examined independent between- within-person associations sleep duration onset on next-day likelihood in a large, longitudinal sample adults under free-living conditions. Methods Participants (N=19,977; 6,593,237 person-nights) wore validated wrist-worn biometric device (WHOOP Strap) for one year. Objective metrics were derived from...
Abstract Study Objectives To investigate the effect of a typical dose caffeine and high consumed in morning, afternoon, evening on subsequent sleep. Methods Using placebo-controlled, double-blind, randomized crossover design, 23 males (25.3 ± 5.0 years) with moderate habitual intake (<300 mg∙day−1) completed seven conditions: placebo, 100 400 mg 12, 8, 4 hours prior to bedtime, 48-hour washout. In-home partial polysomnography sleep diaries were used assess Linear mixed models...
Psychostimulants can be employed as a countermeasure to cognitive declines resulting from insufficient sleep. Although caffeine is the most consumed psychostimulant, consumption cause adverse side-effects, including sleep disturbance. Therefore, there interest in identifying alternative supplements that improve performance without compromising subsequent Here we investigate influence of dose and timing theacrine on using conditions replicate low (100 mg) high (400 morning (12 h prior...
