Thirty-three healthy college students underwent 36 h of continuous SD, with cognitive performance assessed at baseline, following 24 and 36 h of SD. Behavioral results revealed significant impairments in proactive and reactive control, as indicated by increased error rates and longer response times in BX and AY trials, respectively. However, proactive control remained the dominant strategy throughout the SD period, as evidenced by positive Proactive Behavioral Index (PBI) values, smaller P3 and larger CNV amplitudes for cue A, and larger N2 and smaller P3 amplitudes for AY trials. These results provide novel insights into the cognitive mechanisms underlying SD-induced impairments and highlight the robustness of proactive control in sleep-deprived individuals.

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. However, current performance remains exploratory and insufficient for deployment without further refinement.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"201 ","pages":"Article 109130"},"PeriodicalIF":2.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145187778","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}

Participants rated the morality and willingness to cooperate toward resource allocations differing in prosociality (high/low) and fairness (fair/unfair). Behaviorally, sensitivity to fairness was heightened under high prosociality conditions compared to low prosociality, and social status modulated cooperation intentions- fairness effects were more pronounced for high-status allocators. Neurally, the FRN differentiated fairness more strongly under high prosociality, indicating early-stage fairness monitoring modulated by context. The P3 displayed opposing effects by status: fair proposals from high-status allocators elicited larger P3 amplitudes. These findings support a dual-phase model of moral evaluation: the early FRN reflects rapid, context-dependent fairness monitoring, while late-stage P3 integrates social status information to influence cooperative decisions.

While traditional linear EEG analyses have yielded valuable insights, they are limited in capturing the complex non-linear dynamics inherent in EEG signals, potentially obscuring critical aspects of brain-behavior relationships. 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. Advocating for the integration of non-linear EEG analyses alongside conventional methods, this review aims to provide a more comprehensive understanding of the neural underpinnings of sport, exercise, and cognition, paving the way for future research in this evolving field.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"201 ","pages":"Article 109126"},"PeriodicalIF":2.9,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145041983","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}

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 study examines the neural mechanisms underlying four WM subprocesses using event-related potentials (ERPs) and explores the influence of negative mood. Thirty-seven participants completed a cue-version reference-back task after mood induction (negative or neutral) across two sessions, with behavioral and EEG data recorded. Mood changes were assessed via the Positive and Negative Affect Schedule (PANAS) before and after the experiment. A total of 32 participants were included in the final analysis.

Negative mood only reduced substitution costs in RT. The ERP results revealed that gate opening was activated during both the cue phase (550–1000 ms at frontal and central areas) and the probe phase (670–920 ms at central and parietal areas), whereas no gate closing costs were observed in neural activity. Updating was activated at central, parietal, and occipital areas (630–1000 ms post-probe), and substitution was linked to parietal area (710–980 ms post-probe).

These signatures emerge early during visual processing, with each category sensitive to specific types of visual information at different time points. However, it is still not clear what information is extracted during early scene-selective processing, as scenes are rich, complex, and multidimensional stimuli. Here, we tested the hypothesis that early scene-selective activity involves global processing by examining the impact that scene inversion has on visually-evoked Event-Related Potentials (ERPs), particularly the scene-selective P2 component (peaking around 220 ms post-stimulus onset). We recorded ERPs from participants as they were viewing images of faces, objects, and scenes. Images were presented in both upright and inverted orientations and spanned a wide range of category dimensions and properties, preventing the possibility of salient image properties influencing the results. Replicating previous studies, P2 was found to be the first scene-selective component, with higher amplitude in response to scenes compared to faces and objects. Inversion had a clear effect on P2, with a decrease in its amplitude to inverted scenes. No scene inversion effects were observed on P1 and N1, the earlier visually-evoked components. Conversely, face inversion impacted all three components, while inverting objects had no effect on any of the three components.
