Previous research reported associations of the ERN and individual differences in intolerance of uncertainty (IU). These findings imply associations between the subconstructs of IU (prospective and inhibitory IU) and the ERN, which we sought to replicate and extend by testing for causal influences that might elucidate specific mechanisms underlying this association. To test associations of uncertainty and the ERN, a preregistered, randomized-controlled design was employed. After measuring the baseline ERN of <em>N</em> = 120 university students, a subsample was randomly assigned to two groups: While an intervention group (<em>n</em> = 30) performed an unsolvable probabilistic “learning” task intended to induce state uncertainty, a passive control group (<em>n</em> = 30) rested. Subsequently, the ERN was assessed again. Self-reported uncertainty was assessed before and after the intervention. To further increase the statistical power of the replication attempt, we performed a correlation analysis (non-preregistered) by including data from two additional samples collected at different study sites. This analysis comprised psychophysiological data from a total of <em>N</em> = 355 participants. Cross-sectionally, no effects of IU on the ERN emerged. Regarding the state uncertainty induction, the intervention group displayed increased self-reported uncertainty after the intervention, but no evidence emerged for ERN alterations attributable to the intervention. The link between individual differences in IU and the ERN might be smaller and less robust than previous findings suggest, reflecting the understudied character of this association. The absence of evidence for mechanistic changes in the ERN due to a successful induction of state uncertainty further questions a link between IU and the ERN. In line with previous studies that linked increased ERN to anxiety, independent of current clinical status, the ERN seems unaffected by short-term changes such as symptom provocations in non-clinical populations.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"207 ","pages":"Article 112480"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142796493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This systematic review synthesised findings from 22 studies on age-related interoceptive changes and their impact on psychophysiological processes. Results showed age-related declines (48.4 %), no age differences (32.3 %), an age-related increase (16.13 %), and an inverted U-shaped curvilinear relationship (3.23 %) in interoceptive sensitivity across age groups and interoceptive dimensions. Three patterns emerged regarding psychophysiological processes in older adults: altered mind-body connections with age were associated with reduced high-arousal and increased positive emotional experiences, cognitive protective effects, and improved body representation that correlated with better interoceptive sensitivity. These patterns indicate the complex relationships between interoceptive ageing and psychophysiological processes, showing both, aspects of decline and compensatory mechanisms. We propose future research avenues to elucidate the functional significance of different interoceptive dimensions across the lifespan for optimised psychological wellbeing and health behaviours in older adults.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"207 ","pages":"Article 112483"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here the question is addressed how the altered emotional experience is related to altered electro-cortical responses, and about the neural mechanisms underlying regulation itself. To this end, we recorded EEG during a cued emotion-regulation paradigm including negative and neutral pictures. Firstly, based on hypothesis-driven analysis of the Late Positive Potential (LPP), we found that the early fronto-centro-parietal LPP (400–1000 ms) increased when passively viewing negative versus neutral pictures. Reappraisal did not decrease this LPP. Instead, only during reappraisal, the emotion effect on the parietal LPP was sustained until the picture offset. Secondly, we applied a localizer approach to uncover reappraisal effects with other spatiotemporal characteristics than the traditional LPP but did not observe such effects. Despite indications of theta oscillations being associated with cognitive and/or affective control, no significant effects were found on theta activity for emotion processing or reappraisal. Our findings suggest that emotion regulation may affect the LPP in several ways, depending on the task design and including affective as well as more cognitive influences. A potential role for theta in emotion regulation remains to be elucidated.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"207 ","pages":"Article 112467"},"PeriodicalIF":2.5,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142755821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 28 participants were included in the intrahemispheric-interannual FFT coherence analysis, comparing EEG data collected years apart.

Overall, alpha coherence, particularly in the frontal lobe, showed marked long-term stability, suggesting it as a strong candidate for an EEG fingerprint.

Complementary to the previous research, eye movements and late positive potential (LPP) for fixation stimuli and the presaccadic positivity (PSP) and spike potential (SP) before saccade onset, were compared in two groups of OCD and healthy volunteers. Both groups exhibited increased fixation on emotional images, particularly on unpleasant ones, and showed heightened LPP responses without significant between-group differences. However, individuals with OCD had lower PSP and SP amplitudes for unpleasant images compared to the control group, although there were no differences within conditions for each group. These results suggest that while both groups displayed similar effects of unpleasant images on the involuntary orientation of attention, the findings on presaccadic potentials correlate with behavioral data on increased error rate in antisaccade tasks in OCD.

Observational studies report that these risk factors precede neuromuscular and neurodegenerative disorders, especially in old-age miners. Neurodegenerative disorders have electrophysiological, anatomical, and functional changes long before symptoms are seen in older adults. Therefore, this study investigated whether risks faced by miners at young ages were reflected in electrophysiological signals. Twenty-one underground miners and twenty-two above-ground workers matched with them in terms of age, education, and working duration were included in this study. Participants were recorded with a 20-channel EEG during the resting-state (eyes open and closed; EO-EC) and the perception of the International Affective Picture System Paradigm (IAPS). Time-frequency analyses were performed for alpha frequency. Rs-EEG results showed a statistically significant difference in alpha power between the EO and EC states in the control group. However, there was no statistical difference in alpha power between these two conditions in the miners. Additionally, we noted a more pronounced decrease in alpha responses in the posterior region during EC in the miners. The group's main effects were statistically significant in event-related alpha responses during emotional responses. Accordingly, event-related alpha responses of the miner group were lower than the control group in terms of both power spectrum and phase-locking. Underground mine workers are cognitively and emotionally affected by risks in the work environment. Electrophysiological changes seen in young underground workers may be a harbinger of neurodegenerative disorders in miners' old age.
