The current investigation examined pupillometric signals associated with intentional forgetting, as the pupil reflects the activity in the locus coeruleus-norepinephrine (LC-NE) system that is functionally involved in the neural correlates of intentional forgetting. Experiment 1 employed an item-method DF paradigm, where participants were presented with natural scenes, each followed by a memory cue to either remember (R) or forget (F) that scene. At test, participants were asked to judge whether the presented scene was the original studied version (i.e., \"Old\") or a mirrored variant (i.e., \"Lure\"). By comparing pupil dilation during test trials between R-cued and F-cued scenes for both hit and miss trials, we found greater pupil dilation for F-cued miss trials compared to R-cued miss trials, but no difference in pupil dilation between the cue conditions for hit trials. This suggests a unique pupillometric pattern linked to successful intentional forgetting. Experiment 2 was aimed at assessing if memory strength differences could provide an explanation for the observed effect. Instead of DF cues, we manipulated memory strength by repeating a subset of scenes, thereby converting all study items into R-cued items with different degrees of familiarity. We observed no difference in pupil dilation between strongly encoded and weakly encoded scenes at test, indicating that encoding strength by itself did not explain the difference in pupil dilation resulting from intentional forgetting. Together, these findings provide novel evidence that pupil fluctuations during retrieval index successful intentional forgetting.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 8","pages":"e70119"},"PeriodicalIF":2.8,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12317212/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144765324","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}

The insula cortex, a key region for both interoception and sleep, might be a shared neural link. In this study, we examined the role of the insula in linking multiple interoceptive constructs with objectively measured sleep. We also investigated how interoception relates to sleep quality across the adult lifespan at different levels of anxiety. We measured interoceptive accuracy (the objective ability to detect internal signals), interoceptive sensibility (the self-perceived ability to detect these signals), insular volume (using structural MRI), objectively assessed sleep quality (via actigraphy), and trait anxiety in 70 participants aged 18-79. The results indicated that both interoceptive constructs were associated with poorer sleep quality across age, particularly in individuals with higher anxiety levels. We also found that greater insula volume was associated with a stronger subjective belief in one's interoceptive abilities (interoceptive sensibility). Although there was no direct link between insula volume and sleep quality, insula integrity may indirectly influence sleep quality through its association with interoceptive sensibility. These findings highlight the negative relationship between interoception and sleep quality across the adult lifespan. Sleep interventions using mindfulness- or interoception-focused strategies should be implemented with caution, particularly for anxious individuals or those with heightened interoceptive sensibility.

In the present study, we investigated whether location- and frequency-based inhibition of return (IOR) can extend from the auditory modality to the task-irrelevant visual modality using an exogenous cue-target paradigm coupled with electrophysiological recordings. The auditory cue was presented on the left or right speaker, and the auditory target, which appeared 300-500 ms after the cue, was presented at the same or different locations and frequencies. Visual stimuli presented either individually or simultaneously at the center of the screen were disregarded. The results revealed that the frontocentral late component (200-350 ms) in the extracted visual ERP difference waveforms (audiovisual minus auditory) was stronger at different cue-target locations than at the same locations, regardless of whether the cue-target frequency was the same or different. However, no significant differences were observed in the late component between cue-target same and different frequency conditions. These findings provide strong evidence that location-based IORs can spread cross-modally, whereas frequency-based IORs appear to remain modality specific. This pattern highlights the selective nature of auditory-to-visual attentional transfer, which is mediated by shared spatial representations and limited by feature-specific processing pathways.

However, the direct influence of tonic-phasic pupillary activity on cognitive flexibility and cognitive stability-two control modes that potentially trade off with each other-has not been systematically investigated. We examine these associations using a task that imposes varying requirements on flexibility (task switching) and stability (distractor inhibition). The task included ambiguous trials that captured participants' preference for cognitively flexible performance. Participants (n = 51) completed the task with pupillary measurement recording. We find a lower preference to voluntarily switch (lower flexibility preference) in individuals with higher switch costs (lower ability/effort exerted to be flexible) and in individuals with faster RTs on Distractor Inhibition trials (higher stability), indicating a possible trade off between an individual's cognitively stable performance and the preference to be flexible. Examining pupillary data, we show that a larger phasic pupillary response in Task Switch trials is associated with lower switch costs, that is, higher flexibility. Individuals with larger average tonic pupil diameter were less likely to voluntarily switch tasks in ambiguous trials (i.e., lower flexibility preference), contrary to our expectations. Finally, we observed that higher tonic pupillary measures predicted quicker errors on trials measuring cognitive stability and greater overall task disengagement.

The attentional demands associated with using devices such as in-ear headphones and head-mounted displays may be significantly influenced by varying locomotor demands, yet this relationship remains poorly understood. This study investigates the interplay of information presentation modality, movement state, and cognitive task difficulty. In a virtual reality laboratory, 22 participants performed a cued task-switch paradigm with three cognitive task difficulty levels while standing, walking, or walking with perturbations on a treadmill. We used a questionnaire, behavioral, and mobile EEG data to investigate cognitive-motor interference. We find that locomotion interfered with cognitive task performance, and that the presentation modality of task-switch notification modified the nature of this interference. While auditory cue presentation resulted in faster responses under low cognitive load conditions, visual information presentation was less impaired by higher cognitive and locomotor demands. A detailed analysis of the EEG response to cues addressed these differences in terms of multi-modal attentional mechanisms. Hence, information presentation on wearable devices should be tailored to the specific task demands, particularly for cognitively demanding information in mobile work settings.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 8","pages":"e70122"},"PeriodicalIF":2.8,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12319377/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144776060","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}

However, general predictive mechanisms not specific to movements may also play a role.

If efference copies for the suppressed and executed saccade are in conflict with each other, prediction mechanisms based on their information are potentially disturbed, which may affect the processing of saccade-generated stimuli. We compared the N1 and P2 components for pro- and antisaccade-generated sounds with those for visually cued external sounds and found differing temporal dynamics of both components during the course of the experiment, depending on the saccade type. The N1 amplitude for pro- but not antisaccade-generated sounds changed over the course of the experiment, with evidence of an attenuation relative to visually cued sounds at the end. The P2 for prosaccade-generated sounds decreased already earlier than that for antisaccade-generated sounds, which only decreased toward the end of the experiment. These findings suggest that both early (N1) and late (P2) processing of saccade-generated sounds is affected by conflicting efference copies, with the early effect probably reflecting forward model predictions and the later effect indicating agency perception based on these predictions.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 8","pages":"e70114"},"PeriodicalIF":2.8,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308631/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144744481","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 study aimed to investigate both cardiac PSNS and SNS activities to provide a more comprehensive understanding of ToM ability in young adults. Cardiac PSNS and SNS activities were simultaneously measured at rest in 146 participants (mean age = 20.84, SD = 2.86 years) in a cross-sectional study, and in 73 of these participants (mean age = 21.56, SD = 2.70 years) 12 months later. ToM ability was assessed using the Chinese version of the Faux Pas Recognition Test. The results indicated significant uncoupled but reciprocal associations between ToM ability and both cardiac PSNS and SNS activities. Hierarchical regression analysis further revealed that higher cardiac PSNS activity and lower cardiac SNS activity together predicted better ToM ability and its cognitive component, after controlling for possible covariates. Preliminarily, a two-wave cross-lagged panel model demonstrated a significant inverse bidirectional relationship between cardiac SNS activity and ToM ability, along with a positive predictive relationship between ToM ability and cardiac PSNS activity 1 year later. In conclusion, the present study provides direct evidence for a relationship between ToM ability and the simultaneous combination of both cardiac PSNS and SNS activities in young adults.

Results revealed that for single outcomes, concordant responses (e.g., avoidance to the avCS+) were faster than forced discordant responses (e.g., approach to the avCS+). During anticipation, gaze fixations shifted towards the spatial location associated with the concordant response for single-outcome stimuli (e.g., upward for avoidance of avCS+). Conflicting stimuli elicited intermediate behavioral and gaze patterns at the group level, while exploratory analyses revealed substantial individual differences: High avoiders (i.e., participants showing an overall high proportion of avoidance) exhibited slower approach responses and greater threat-focused visual attention compared to low avoiders. Decreased heart rate in response to all CSs suggests a general preparation of behavioral responses, while increased pupil dilation during the anticipation of aversive stimuli indicates threat-related processing.
