The present study aimed to explore how the experience of searching for expectation-incongruent targets affects trial-by-trial visual search through expectancy updating and cognitive control processing. Here, we analyzed event-related potentials (ERPs) related to behavioral results during the search tasks. The results revealed distinct cognitive control mechanisms under similar behavioral results in the context of different type of associations. Expectation violations in long-term associations facilitated expectation updating through proactive control, whereas reactive cognitive exhibited a more prominent role in the short-term associations condition.

This study aims to explore the neuroelectrophysiological characteristics and diagnostic value of social anxiety by integrating event-related potentials (ERP), event-related spectral perturbation (ERSP), and machine learning methods. A total of 128 participants with varying levels of social anxiety completed an emotional face Go/No-Go task, during which electroencephalographic (EEG) data were collected for ERP and time-frequency analyses. The results revealed that individuals with social anxiety exhibited abnormalities throughout the entire process, from early perception to late regulation: during the early processing stage, signs of hypervigilance (enhanced N1), deficits in conflict monitoring (abnormal N2 latency), and biases in emotional evaluation (flattened P2) were observed, accompanied by increased synchronization in the delta/theta frequency bands. In the late regulation stage, there were signs of disorganized classification functions (reversed P3), ineffective emotional maintenance (absence of LPP regulation), and excessive recruitment of compensatory attentional resources (enhanced alpha/beta desynchronization). These EEG indicators were found to be broadly correlated with symptoms of social anxiety. The support vector machine (SVM) model constructed from the selected features demonstrated excellent performance on the original dataset (accuracy 88.462 %, AUC 90.196 %) and maintained good generalization performance on an independent validation dataset (<em>n</em> = 38), achieving an accuracy of 68.421 % and an AUC of 80.000 %. This study provides new insights for the objective diagnosis of early social anxiety and the exploration of its neurophysiological mechanisms, while also indicating directions for the development of targeted intervention strategies.

Electroencephalography (EEG) and skin conductance level (SCL) data were recorded during eyes-closed resting and meditation states in 42 young adults (<em>M</em>_<em>age</em> = 21.05 years; 26 females) across two sessions (pre-training, post-training) six weeks apart.

Results revealed a significant reduction in alpha amplitude (8–13 Hz) during meditation compared to rest. Additionally, post-training, there was a smaller alpha reduction during meditation in the mindfulness group, particularly in the frontal/posterior region, evidence of a possible trait effect. While SCL remained stable over meditation and rest, a decrease was evident in both groups post-training, indicating reduced arousal. However, no significant associations were found between SCL and global alpha amplitude. Together, these findings suggest mindfulness meditation reduces alpha band activity, likely reflecting enhanced attentional engagement rather than an arousal change, supporting the view of mindfulness meditation as a state of relaxed alertness. The present findings provide new insights into the mechanisms underlying mindfulness meditation, emphasising the importance of alpha band activity in attentional control, which may contribute to its health benefits, including improved emotional regulation and cognitive functioning.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"214 ","pages":"Article 113197"},"PeriodicalIF":2.5,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a laboratory-controlled setting, we examined individual differences in alertness alteration during overnight wakefulness—a more common form of sleep loss in real life—and explored the associated resting-state EEG spectral signatures. Forty-five participants remained awake from 22:00 to 06:00, during which they completed subjective ratings, a 10-min psychomotor vigilance task (PVT), and resting-state EEG recordings every 2 h. Based on the changes in overnight PVT performance, participants were grouped as vulnerable (<em>N</em> = 20) or resilient (N = 20). Vulnerable individuals exhibited larger variations in frontal theta power, whereas resilient individuals demonstrated relatively stable resting-state EEG activities during prolonged wakefulness. Furthermore, higher theta power in the parietal region was observed in vulnerable people before prolonged wakefulness, which might be a predictor of vulnerability to prolonged wakefulness.

Information is often perceived as a reward, and curiosity can manifest as the intense, even fearless, pursuit of potential rewards. However, curiosity is also considered to be a rational process, requiring individuals to weigh potential risks against anticipated benefits. To investigate the multifaceted nature of curiosity, this study used a cross-lagged panel model to examine the relationships between sensitivity to reward (SR), sensitivity to punishment (SP), and curiosity. A predictive model was then constructed using resting-state functional connectivity data through connectome-based predictive modelling. Building on the cross-lagged panel model results, a mediation analysis was conducted to investigate the mediating roles of SR and SP in the relationship between the predictive network and curiosity. The findings revealed that SR positively predicts curiosity and that the relationship between SP and curiosity is reciprocal and negative, with the negative prediction of SP being significantly stronger. Additionally, a negative curiosity prediction network was identified, with the strongest contributions being intra- and internetwork functional connectivity involving the motor, cerebellar, limbic and medial frontal networks. Finally, the curiosity prediction network was found to operate via the enhancement of SP and attenuation of SR. These findings provide preliminary evidence for associations between SR, SP, and curiosity over time and the incentive-driven yet adaptive nature of curiosity.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"213 ","pages":"Article 112601"},"PeriodicalIF":2.5,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, we conducted a systematic review of the literature examining religiosity and/or spirituality and cardiovascular reactions to acute stress. Electronic databases were systematically searched (PubMed, PsycArticles, PsycInfo, CINAHL and Web of Science). After removal of duplicates, screening titles and abstracts, twelve peer-reviewed studies were included in the review. Overall, the majority of studies reported on an inverse relationship between religiosity and/or spirituality and cardiovascular reactivity, showing higher levels of religiosity and spirituality were associated with attenuated cardiovascular responses. This was particularly evident when measures assessed facets of intrinsic religiosity and focused on internalized spiritual beliefs, focusing on spiritual aspects such as finding meaning and purpose in life. However, in three studies, religiosity and/or spirituality showed exaggerated cardiovascular responses, importantly these studies examined religious/spiritual struggles, indicating that religiosity/spiritual struggles can have a negative impact on health. To date, no study has controlled for religiosity when examining spirituality and cardiovascular reactivity, or vice versa, to explore whether the outcomes differ. Overall, this review highlights that religiosity, and spirituality have potential health benefits for cardiovascular reactivity, however religious/spirituality struggles can diminish these positive effects. It is a priority for future research to clearly define, differentiate and measure the constructs of religiosity and spirituality separately, as both have demonstrated beneficial effects on cardiovascular reactivity.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"213 ","pages":"Article 112596"},"PeriodicalIF":2.5,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144090519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
