Nature, Published online: 22 June 2026; doi:10.1038/d41586-026-01957-z Researchers have long discussed the replication crisis. Now it’s time to tackle another problem in the behavioural sciences: generalizability.

As a kid, I did my best to avoid exercise. As an adult, I endured it for the sake of my health. Then I set myself a clear goal – and motivation was no longer an issue It’s fair to say I don’t come from a long line of athletes. When I was growing up in the 1990s, sport was something other people did; we were not a family who cycled, much less jogged. In PE I was the wheezing child hiding behind th…

ObjectiveAmong evidence-based treatments for personality disorder (PD), mentalization-based treatment (MBT) represents a manualized, long-term treatment. Both MBT and non-manualized psychotherapeutic treatments (NMT) are currently applied for patients with PDs in Norway. This clinical population is characterized by varying impairment of personality functioning (PF). Few have investigated how MBT …

BackgroundSuicide risk remains difficult to predict, particularly among populations exposed to interpersonal violence. Although psychopathic traits have been linked to suicidal behavior, emerging evidence suggests these associations vary across psychopathy domains. The present study examined whether overall psychopathy and specific psychopathy facets were associated with suicide risk among violen…

BackgroundFear of childbirth is an important perinatal mental health concern, particularly among women of advanced maternal age. However, the specific interrelations between spousal support and fear of childbirth remain unclear.MethodsThis cross-sectional study recruited 279 pregnant women of advanced maternal age from a tertiary hospital in Henan, China, using convenience sampling. Spousal suppo…

BackgroundDespite strong evidence for cognitive behavioral therapy for insomnia (CBT-I), uptake remains constrained by poorly understood cognitive, attitudinal, and practical barriers. This study examined determinants of willingness to enroll in sleep improvement programs among adults at risk of sleep disorders—including insomnia, obstructive sleep apnea, and comorbid psychological distress—atten…

Dogs and cats both give you a brief mood lift, but only one of them seems to raise your stress levels too.

This study investigated the psychological mechanisms linking challenge-skills balance to psychological wellbeing among team-sport athletes, considering team identification and flow experience as the fundamental drivers of this relationship. A sample of 281 team-sport athletes completed an online survey comprising measures of challenge-skill balance, team identification, flow, and wellbeing. Resul…

IntroductionPsychological safety is increasingly recognized as a key determinant of athletes’ wellbeing and sustainable performance, particularly in youth sport. Despite growing interest in the construct, validated tools to measure it remain largely limited to English contexts. This study thus aimed to validate a French translation of the Sport Psychological Safety Inventory (SPSI).Materials and …

Guided by the Theory of Motivated Information Management (TMIM), this study examines how Chinese incoming first-year university students (N = 417) manage pre-enrollment uncertainty through information seeking. Data were analyzed using structural equation modeling. Results show that uncertainty discrepancy positively predicts anxiety. Anxiety was positively associated with outcome expectancy but n…

Acceptable risk is often defined in technical, regulatory, or ethical terms. Yet people do not decide that a risk is acceptable simply by estimating probabilities or expected harms. Judgments of acceptability are also shaped by how a hazard is perceived, whether those responsible for managing it are trusted, and whether exposure is regarded as fair. This mini review brings together research on ri…

IntroductionPre-shot strategy selection in golf occurs under relatively low external time pressure, allowing players to become attuned to the affordances of the hole before executing the tee shot. The association between such pre-shot affordance engagement and scoring outcomes has, however, received limited empirical attention. Drawing on ecological dynamics, we conceptualised aggressive versus c…

BackgroundChildren with solid tumors experience prolonged treatment, repeated hospital visits, and psychosocial stressors. This exploratory single-center cross-sectional study evaluated anxiety symptoms, depressive symptoms, and health-related quality of life in children with solid tumors and examined their associations with selected sociodemographic, clinical, school functioning, and social func…

Socially meaningful symbolic cues are common in everyday visual environments, yet the timing with which they diverge from neutral objects during neural processing remains unclear. This study examined the temporal dynamics of one culturally meaningful class of symbolic cues, national-symbol icons, using event-related potentials (ERPs). Thirty-four Chinese university students completed a within-sub…

A nationwide Icelandic study found that 6.9% of women aged 18-69 reported trauma-associated sleep disturbances in the past month. These symptoms were most common after sexual or physical violence, recent or repeated trauma, and were strongly linked to PTSD, anxiety, depression, and general sleep problems.

This paper extends an earlier analysis of the functions attributable to consciousness, applying it to a modular/constitutive model that limits the role conscious sensations are allowed to play in integrative processes operating at scale. The focus is on conscious vision because of the challenge it poses for any theory of consciousness, of how to account for a 2-dimensional perceptual display. For…

The global shift toward a service–oriented economy has made emotional labor an inevitable occupational demand, yet its impact on frontline bank employees' occupational health remains underexplored. Drawing on Conservation of Resources theory, this study investigates the relationships among emotional labor, job burnout, turnover intention, and perceived organizational support(POS), distinguishing …

The study used the PERMA Profiler of Chinese Version, Regulatory Emotional Self-Efficacy Scale, Perceiv…

ObjectivesThe objective of this study is to understand whether individuals show different search patterns for health-related terms on Google Trends depending on their cultural background.MethodThis study analyzed Google Trends data for health-related terms in both the United States and South Korea.ResultsThe result suggests that Americans show stronger temporal landmark effects than Korean with h…

Studying the developmental origins of sociomoral cognition is challenging because preverbal infants have limited means to express their thoughts through verbal communication or overt action. Developmental research has therefore relied heavily on infants' looking behavior, often treating gaze as an indicator of expectation or attention. While these approaches have yielded substantial insights into…
