Despite considerable research interest, results have shown considerable variability across studies. Several meta-analyses have been conducted to help address this inconsistency. However, conducting a meta-analysis requires researchers to make numerous decisions, such as defining inclusion criteria and analytical techniques. In response to this challenge, a ‘multiverse’ approach can be used to simultaneously explore a range of different potential and realistic scenarios by systematically varying these analytical decisions. In this study, we performed a multiverse meta-analysis to investigate how researcher decisions can influence outcomes in meta-analyses of oxytocin administration studies. We systematically varied inclusion criteria, data synthesis models, and methods for correcting publication bias across 530 effect sizes derived from 185 studies, conducting 256 distinct meta-analyses. Our results demonstrate that summary effect estimates can vary considerably depending on meta-analytic decisions (from <em>d</em> = −0.16 to <em>d</em> = 1.45). Notably, meta-analyses with neurotypical populations tended to yield larger effect sizes than non-neurotypical populations, and multiple administrations studies tended to yield larger effect sizes than single administration studies. Furthermore, summary effect estimates can substantially vary according to the applied publication bias correction method. Our findings also demonstrated that the current evidence mostly supports the presence of the effect of oxytocin across domains, regardless of meta-analytic choices, as over 90% of the observed meta-analyses exceeded the range of bootstrapped meta-analyses assuming a null effect. These results warrant future research on how different contexts may impact the robustness of the effects of oxytocin, while underscoring the value of meta-analysis pre-registration to facilitate the transparent evaluation of meta-analyst decision-making.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"201 ","pages":"Article 109112"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144979668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-five healthy young adults underwent a prolonged period of wakefulness for one night at their habitual bedtime. Participants completed a 10-minute psychomotor vigilance task and resting-state electroencephalography recording from 22:00 (baseline) to 06:00 at 2-hour intervals.

Vigilance during prolonged wakefulness exhibited a gradient deterioration that remained stable until 02:00, then sharply declined at 04:00. At 02:00, the coupling between the frontal delta phase and occipital gamma amplitude significantly increased and showed a significant negative correlation with lapses, potentially indicating a top-down compensatory mechanism. Additionally, increased delta activity in parietal areas was significantly correlated with increased mean reaction time and lapses at 04:00. These findings reveal the dynamic fluctuations of neural activity during prolonged wakefulness and suggest that the disconnection between anterior and posterior brain regions may be one of the critical factors contributing to deterioration in vigilance performance.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"201 ","pages":"Article 109138"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under UC-inconsistent condition, results showed the same reward effect and the opposite unitization effect on Prs as Experiment 1. ERP results revealed that in the test phase, reward effects were found in FN400 on frontal location and LPC on frontal and central location with more positive amplitudes for rewarded stimuli, indicating more semantic unitization processing and cognitive efforts putting into them, and conceptual unitization enhanced Prs through familiarity and recollection processes.

While extensive research has examined the communicative potential of human sweat, the mechanisms underlying emotional sweat production remain underexplored. This study employed a data-driven approach with a large sample of sweat donors (N = 334; most participants were university students) to investigate the relation between sweat production and the emotional state of males and females across three conditions – fear, happiness, and rest. Four key questions were addressed: (i) Do males produce more sweat than females across emotional conditions? (ii) Does sweat production vary as a function of emotional experience? (iii) Is sweat production associated with self-ratings of emotional experience? and (iv) Are there sex differences in these associations? Results revealed that males produced significantly more sweat than females in fear-inducing conditions, which also showed the highest overall sweat production. Contrary to prior findings, happiness-related sweat production did not exceed that of rest in either sex, a discrepancy potentially due to contextual factors. Moreover, sweat production was positively associated with reported negative emotional experience during the fear-inducing sessions, but only for males. This suggests that male, but not female, donors may have the capacity to encode emotional intensity in sweat production. These findings provide new insights into the physiological and contextual factors that shape emotional communication through sweat, with potentially important implications for future research.

This perspective article first reviews contemporary research using linear EEG methods to examine neural correlates as both antecedents and consequences of sport and exercise behaviors. We then discuss the non-linear nature of brain dynamics and the advantages of non-linear EEG analyses—such as multiscale entropy (MSE)—for revealing adaptive neural changes induced by physical activity. Finally, we introduce two advanced non-linear EEG techniques, cross-frequency coupling (CFC) and Holo-Hilbert Spectral Analysis (HHSA), which, though yet to be applied in sport and exercise science, hold significant promise for uncovering complex neural mechanisms overlooked by traditional linear approaches.

While EEG-based brain activation measures combined with machine learning have shown promise for DD screening, these approaches often lack validation on independent participants, a crucial step for practical application. This study developed an EEG-based screening approach and investigated the neural correlates of DD in Chinese children. EEG was recorded from 130 children (82 DD, 48 typically developing; 7–11 years) during resting state (eyes-open, eyes-closed) and verbal working-memory tasks. After artifact rejection, signals were segmented and converted to functional-connectivity (FC) measures across delta, theta, alpha, and beta bands using Pearson correlation coefficients (PCC), phase-locking value (PLV), and a rho (RHO) measure. Segments were split into two non-overlapping samples to ensure participant-level independence: Sample 1 for training and five-fold cross-validation of a convolutional neural network, and Sample 2 for held-out cross-sample evaluation. Balanced accuracy (BA) served as the primary outcome, with significance assessed by permutation testing. Beta band matrices were most informative: the eyes-open beta-band RHO achieved the highest within-sample performance (BA = 97.47 %), and the eyes-closed beta-band PLV yielded above-chance cross-sample performance (BA = 64.99 %, permutation p &lt; .001). Given the reduced cross-sample BA, further validation in larger and more diverse cohorts and other language systems is needed to establish the model’s generalizability. Discriminative FC patterns revealed that children with DD exhibited reduced temporal-parietal and central connectivity but increased frontal-central connectivity, likely reflecting compensatory mechanisms. Within the DD group, stronger FCs showed significant negative correlations with Chinese word reading accuracy and fluency. These results highlight functional network abnormalities in Chinese children with DD and offer preliminary evidence for EEG-based screening.
