Previous research has shown that sending a facial emotional expression influences the evaluation of response expressions, but the mechanisms behind this effect remain unclear. In a preregistered experiment, 68 participants were asked to send an emoji (happy, neutral, and angry) to a virtual agent in front of them, whereupon the agent reacted with either a smiling or frowning facial expression. Valence and arousal ratings were obtained and mimicry responses to the agent's expression were measured via facial EMG of the Zygomaticus and Corrugator muscles. The results show that being smiled at is more pleasant and elicits greater Zygomaticus activation when the smile is received as a response to a happy emoji compared to an angry emoji. In contrast, being frowned at is less pleasant and increases Corrugator activity when the angry expression is received as a response to a happy emoji compared to an angry emoji. Finally, we found that sending an emoji resulted in activation of facial muscles corresponding to the valence of the emoji. The results support the role of affiliative mechanisms in the exchange of facial expressions but also demonstrate that persons are sensitive to the congruency between emotional signals of sender and receiver. These effects might be driven by physiological feedback. By implementing digital emotional expressions, the present study dissects the communicative act from the motor display of a facial expression and thus allows us to probe mechanisms behind social interactions in real and digital worlds.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70137"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12421215/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we conducted two experiments to investigate how state anxiety affects conflict control across different control contexts and to explore the associated temporal dynamics. The threat of shock paradigm was employed to induce state anxiety. Participants completed the Stroop task under alternating safe and threat states, while EEG data were recorded. In Experiment 1, equal proportions of congruent and incongruent trials were used to create a balanced context. Experiment 2 manipulated trial proportions to induce either proactive or reactive control contexts. Significantly higher subjective anxiety ratings and startle reflexes in the threat state confirmed the successful induction of state anxiety in both experiments. Key findings revealed that in the balanced context, state anxiety enhanced conflict resolution efficiency, manifested by shortened reaction times and decreased sustained potential (SP) amplitudes for incongruent trials under the threat state. In the reactive control context, state anxiety impaired conflict monitoring efficiency, as evidenced by reduced N450 difference waves (incongruent minus congruent trials) under the threat state. This reduction was primarily driven by enhanced N450 amplitudes in congruent trials. Furthermore, enlarged SP difference waves were observed, indicating compensatory recruitment of additional cognitive resources to counteract the impaired monitoring process. Conversely, in the proactive control context, neither behavioral nor neural indicators were affected by state anxiety. These results demonstrate that the impact of state anxiety on conflict control depends critically on the control mode engaged by the task context, offering novel insights into the complex relationship between anxiety and cognitive control.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70143"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145001373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there is evidence that these fibers modulate nociceptive input, their influence on the processing of other somatosensory afferent activity remains largely unknown. In this study, we explored how slow brushing (CT-optimal stimulation) modulates somatosensory evoked potentials (SEPs) elicited by electrical stimulation of the median nerve (occurring at 0.7 to 3.7 s after stimulus onset), compared to vibration (at 200 Hz) and no touch, in 30 healthy participants. CT-targeted stimulation was delivered using a robotic arm developed in-house equipped with a cosmetic brush, which applied slow brushing movements at CT-optimal speeds (~3 cm/s) over the dorsal forearm. Vibrotactile stimulation, targeting A-beta fibers, was delivered using vibration motors adjacent to the brushed area, with intensity calibrated to match the perceived strength of brushing. SEPs were recorded under these three conditions. Our results showed no differences between slow brushing, vibration, and no touch conditions in the amplitude of early SEPs recorded over the somatosensory cortex (N20, P25, N30, and P45), which may indicate that CT stimulation does not affect early cortical processing of somatosensory information. However, a reduced frontocentral P150 SEP component was observed during slow brushing compared to the other conditions. This finding suggests that CT stimulation may reduce somatosensory input transmitted through the lemniscal system, possibly engaging brain areas involved in attentional and cognitive processing.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70146"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12415938/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145016123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Loss aversion, a crucial aspect of risk attitudes, whose behavioral performance and neural mechanism in group decision contexts remain unclear, differs from other risk attitudes such as risk aversion. Using behavioral and electroencephalography (EEG) experiments with non-student and student samples, we conducted an exploratory study to examine the behavioral performance and neural mechanisms of loss aversion in group decision contexts. Behaviorally, we found a reduction effect of loss aversion in group decision contexts compared to individual decision contexts. ERP results from the average and single-trial analyses jointly found that individuals are less sensitive to losses and gains in group (vs. individual) decision contexts, as evidenced by the vanishing Feedback-related Negativity (FRN) and P3b differences to losses and gains. We also found a significant negative correlation between the loss aversion coefficient and FRN amplitude induced by losses both in individual and group decision contexts, which indicated the relationship between loss aversion and neural signals that process loss outcomes. Furthermore, machine learning analyses revealed that EEG features exhibit a high accuracy rate of 81.25% in predicting the decision contexts. This finding underscores the intricate relationship between neural activity and loss aversion across varying decision contexts, highlighting the potential of neurophysiological activity to elucidate the underlying cognitive processes involved in loss aversion. This paper advances our understanding of loss aversion in group decision contexts by providing multiple pieces of evidence for behavioral performance, neural activities, and machine learning. Findings can help to optimize group decision-making processes and resource allocation, and to reduce inefficiencies caused by irrational behavior and resistance to beneficial changes.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70155"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145131854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when individuals learn that their opinion-based ingroup is growing or shrinking, they may experience this stress in different ways, namely as a threat or a challenge. In a preregistered study (N = 203 Dutch university students), we examined among host society members how progressive and conservative changes (vs. stability) in public opinion on migration interacted with their political ideology to influence cardiovascular reactivity indicative of challenge and threat. Electrocardiography, impedance cardiography, and blood pressure were continuously measured during a one- to three-minute speech task in which participants reflected on the future of interethnic relations in the Netherlands. Additional self-reported outcomes, including demand and resource appraisals and prejudice towards migrants, were assessed after the speech task. As predicted, progressive change (vs. stability) in public opinion led leftists to exhibit a cardiovascular pattern indicative of relative challenge (relatively lower total peripheral resistance and higher cardiac output) and rightists to display a cardiovascular pattern indicative of relative threat (relatively higher total peripheral resistance and lower cardiac output). Additional analyses suggest that progressive change (vs. stability) increased leftists' resource appraisal regarding the speech and reduced their prejudice towards migrants, while both progressive and conservative changes (vs. stability) increased rightists' prejudice. These findings highlight that a growing opinion-based ingroup size can function as a resource for coping with the stress of forming and expressing one's opinion on a sensitive societal issue.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70140"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12411664/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145001346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is common practice to characterize breathing by using a block average breathing rate, phase, or amplitude. While these features are useful for measuring the central tendencies of breathing, they do not capture the structure of the patterns of change in its activity over time (i.e., breathing dynamics) whose relationship with affective and cognitive processes remains unclear. To fill this knowledge gap, we characterized breathing dynamics by a set of measures that capture the breathing signal's rate and amplitude central tendency, variability, complexity, entropy, and timescales. Then, we conducted a principal components analysis and demonstrated that these metrics capture similar, yet distinct features of the breathing rate and amplitude time series. Next, we showed that breathing dynamics change across rest and task conditions, suggesting they may be sensitive to changes in behavioral states. Finally, using multivariate analyses, we demonstrated that breathing complexity and entropy in the resting state are strongly and positively correlated with anxiety levels, while breathing variability in the task state is strongly and negatively associated with working memory performance. Our findings extend the current understanding of how breathing is associated with affective and cognitive processes by highlighting the key role of dynamics in that relationship.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70149"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12424284/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent evidence from tasks focusing on the regulation of response conflict and of switching between tasks suggests a consistent relationship between aperiodic EEG activity and task conditions that are likely to elicit a more persistent versus more flexible control style. Here we investigated whether this relationship between metacontrol and aperiodic activity can also be demonstrated for working memory (WM). We analyzed EEG and behavioral outcomes from two independent samples performing the reference-back task, providing an internal replication of the obtained findings. In both studies we found significant increases in the aperiodic exponent when new information needs to be taken in, showing that the updating of WM is likely associated with a metacontrol bias towards persistence. This observation demonstrates a role of aperiodic activity and/or mechanisms associated with changes in this activity in a memory task, which suggests that the relationship between metacontrol and aperiodic activity extends beyond tasks with particular response-selection demands. Further, metacontrol adjustments do not seem to create particular states that differ in aperiodic activity, but rather to bias the way selections are carried out, presumably by reducing aperiodic activity whenever the selection is particularly challenging. We advocate that the aperiodic activity observed in EEG signals represents a valid indicator of the neural dynamics underlying metacontrol, portraying the brain's inherent potential to self-reorganize and alter neural functions to mutable environmental conditions.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70148"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12421218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is commonly observed in cueing studies, which show that when attention is deployed to a known target location that happens to fall on a visual object, responses to targets that unexpectedly appear at other locations on that object are faster and more accurate, as if the object in its entirety has been visually prioritized. However, this notion has recently been challenged by results suggesting that putative object-based effects may reflect the influence of hemifield anisotropies in attentional deployment, or of unacknowledged influences of perceptual complexity and visual clutter. Studies employing measures of behavior provide limited opportunity to address these challenges. Here, we used EEG to directly measure the influence of task-irrelevant objects on the deployment of visual attention. We had participants complete a simple visual cueing task involving identification of a target that appeared at either a cued location or elsewhere. Throughout each experimental trial, displays contained task-irrelevant rectangle stimuli that could be oriented horizontally or vertically. We derived two cue-elicited indices of attentional deployment-lateralized alpha oscillations and the ADAN component of the event-related potential-and found that these were sensitive to the otherwise irrelevant orientation of the rectangles. Our results provide evidence that the allocation of visual attention is influenced by objects boundaries, supporting models of object-based attentional prioritization.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 9","pages":"e70147"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12432486/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145055652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the effects of exercise-induced cardiac changes on visual perception and electrophysiological activity are unclear. Here, we aimed to investigate the relationship between conscious visual perception, neural activity, and cardiac responses during exercise. Thirty healthy participants performed a perceptual suppression task while engaging in light-intensity stationary cycling, with EEG and ECG activity recorded simultaneously. Our study shows that the probability of perceptual suppression decreased during cycling. Parieto-occipital alpha amplitudes (8-12 Hz) also decreased during cycling, but this reduction did not correlate with the decrease in perceptual suppression. Additionally, cycling decreased heartbeat-evoked potential (HEP) amplitudes, indicating altered neural processing of cardiac signals during exercise. However, these exercise-induced changes in HEP amplitudes did not predict perceptual outcomes. Moreover, changes in heart rate in response to cycling did not correlate with changes in perceptual suppression rates, pre-random dot motion stimulus alpha, or HEP amplitudes. These findings indicate that while exercise modulates conscious visual perception, the associated changes in alpha activity, heart rate, and HEPs do not fully explain this effect.

Although similar neural mechanisms have been proposed for error and feedback processing, it remains unclear whether the processing of errors as indexed by external feedback, reflected in the feedback-related negativity (FRN), is altered in OCD. Likewise, it is currently unknown whether performance monitoring in OCD differs between learning from self-performed and observed outcomes. The present study compared OCD patients (n = 27) with healthy controls (HCs; n = 27) and patients with social anxiety disorder (SAD; n = 29) in an active and observational variant of a probabilistic feedback learning task while EEG was recorded. Compared to HCs, OCD patients showed generally impaired task performance across both active and observational learning, as well as more indecisive choice behavior. This was accompanied by generally more positive amplitudes of the FRN, with enhanced valence coding for active compared to observational learning, driven by more positive FRN amplitudes for wins. However, no differences were found for losses. Overall, these results suggest deficient reward-rather than punishment-processing in OCD. Similar performance monitoring alterations in OCD and SAD imply reliance on shared, disorder-general mechanisms.
