Here, we investigate associations among EEG aperiodic slope, temperament, and maternal internalizing (anxiety and depression) symptoms in a large cohort of typically developing infants. A steeper slope was associated with higher scores on the temperament domains of orienting/regulation and surgency but was not associated with negative affectivity. Maternal symptoms did not appear to be directly associated with the slope, but the slope moderated the association between maternal symptoms and temperament. Specifically, a steeper slope was associated with a stronger negative association between maternal internalizing symptoms and infant orienting/regulation. These results demonstrate associations between slope and behavior as early as infancy, which may reflect early differences in the development of global inhibitory networks. Longitudinal research in early childhood is necessary to better understand the nature of these relations during development and their potential impact on later socioemotional outcomes.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14757"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11789922/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932621","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}

Leveraging the rich temporal dynamics of resting-state pupil fluctuations, the present study investigated the association between the aperiodic exponent of pupil fluctuations and the neural excitation/inhibition balance in attentional processing. In separate phases, we recorded participants' pupil size during resting state and assessed their attentional orienting using the Posner cueing tasks with different cue validities (i.e., 100% and 50%). We found significant correlations between the aperiodic exponent of resting pupil fluctuations and both the microsaccadic and behavioral cueing effects. Critically, this relationship was particularly evident in the 50% cue-validity condition rather than in the 100% cue-validity condition. The microsaccadic responses mediated the association between the aperiodic exponent and the behavioral response. Further analysis showed that the aperiodic exponent of pupil fluctuations predicted the self-rated hyperactivity/impulsivity trait across individuals, suggesting its potential as a marker of attentional deficits. These findings highlight the rich information contained in pupil fluctuations and provide a new approach to assessing the neural excitation/inhibition balance in attentional processing.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14755"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932619","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}

Although studies have shown that direct exposure to stress impacts neural responses to threat-relevant stimuli, less is known about how neighborhood characteristics more generally (e.g., living in neighborhood characterized by high crime risk, whether or not the individual directly experiences any crime) may impact children's neural responses to threat. To address this question, we examined links between census-derived indices of neighborhood crime and neural reactivity to emotional stimuli in a sample of 100 children (Mage = 9.64, 54% girls, 65% non-Hispanic White) and whether these differ for children from minority backgrounds compared to non-Hispanic White children. Focusing on the late positive potential (LPP) event-related potential (ERP) component, we examined neural reactivity to threat-relevant stimuli (fearful faces) as well as nonthreat-relevant negative (sad faces) and positive (happy faces) stimuli across low, medium, and high intensities (morph levels). We found that levels of neighborhood crime risk were associated with larger LPP amplitudes for high-intensity fearful, but not happy or sad faces, but only among children from racial/ethnic minority backgrounds. This suggests that levels of crime risk within one's neighborhood may be a more salient stressor for children from minority racial-ethnic groups than for non-Hispanic White children.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14759"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932623","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}

It is often used when in vivo exposure is not possible, too stressful for patients, or would be too expensive. The Bio-Informational Theory implies that imaginal exposure is effective because of the perceptual proximity of mental imagery to real events, whereas empirical findings suggest that propositional thought of fear stimuli (i.e., thinking about the stimuli without seeing them in the mind's eye) could be sufficient. To investigate whether mental imagery or propositional thought is crucial for the success of imaginal exposure, participants with the rare state of aphantasia (= absence of sensory mental imagery) and two control groups were subjected to a fear conditioning paradigm followed by imaginal exposure and a reinstatement procedure. During imaginal exposure, a control group (N = 30) stared at a bright screen to disrupt visual imagery by incoming luminance (=simulated aphantasia), while a second control group (N = 30) and participants with actual aphantasia (N = 30) kept their eyes closed. Results showed successful extinction in all groups, thus demonstrating that imaginal extinction is possible using propositional thought. Moreover, exploratory analyses revealed less subjective fear in people with aphantasia during the fear conditioning procedure, potentially due to similar mechanisms as in alexithymia, that is, a decoupling between physiological arousal and emotional experience.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14756"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11755224/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143024673","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 research has proposed that transcutaneous auricular vagus nerve stimulation (taVNS) modulates indirect physiological markers of LC-NE activity, although its effects on vigilance have not yet been examined. Aiming to develop a safe and noninvasive procedure to prevent vigilance failures in prolonged tasks, the present study examined whether taVNS can mitigate vigilance loss while modulating indirect markers of LC-NE activity. Following a preregistered protocol (https://osf.io/tu2xy/), 50 participants completed three repeated sessions in a randomized order, in which either active taVNS at individualized intensity set by participant, active taVNS set at 0.5 mA for all participants, or sham taVNS, was delivered while performing an attentional and vigilance task (i.e., ANTI-Vea). Changes in salivary alpha-amylase and cortisol concentrations were measured as markers of LC-NE activity. Self-reports of feelings associated with stimulation and guessing rate of active/sham conditions supported the efficacy of the single-blind procedure. Contrary to our predictions, the observed vigilance decrement was not modulated by active taVNS. Pairwise comparisons showed a mitigation by active taVNS on cortisol reduction across time. Interestingly, Spearman's correlational analyses showed some interindividual effects of taVNS on indirect markers of LC-NE, evidenced by positive associations between changes in salivary alpha-amylase and cortisol in active but not sham taVNS. We highlight the relevance of replicating and extending the present outcomes, investigating further parameters of stimulation and its effects on other indirect markers of LC-NE activity.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14670"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11775886/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142018405","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}

Moreover, high-intensity motivated emotional contexts result in enhanced P2 and LPP.

Athletes are highly engaged in performance-driven physical training and often incorporate-to varying degrees-sensorimotor training into their routines. In this study, we investigated the role of individual differences in interoception by comparing professional athletes of different performance levels and both sexes with recreational athletes and controls, applying a three-dimensional model of interoception. Twenty-six elite athletes, 52 recreational athletes, and 50 college students were recruited from national sports teams, local sports training centers, and local universities. We used the Multidimensional Assessment of Interoperative Awareness (MAIA), the Heartbeat Detecting Task (HDT), and a numeric rating scale based on HDT to measure interoceptive sensibility, accuracy, and awareness. At average, athletes showed significantly higher interoceptive sensibility, interoceptive accuracy, and interoceptive awareness than controls. Elite athletes reported significantly higher scores in all measures of interception compared to recreational athletes. Intriguingly, Non-Distracting for interoceptive sensibility was positively correlated with the level of experience in elite athletes. Male athletes had better interoceptive sensibility and interoceptive awareness compared to female athletes in the elite group, while no significant sex differences were detected in the other two groups. These results indicated that level of sport experience and sex are associated with differences in interoceptive accuracy, interoceptive sensibility, and interoceptive awareness. It also suggests that interoceptive ability is possibly an experience-dependent trait for athletic performance, which provides insight for improving sports performance through an approach of enhancing interoceptive ability.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14766"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143047308","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}

As such, there is a growing need to identify correlates of self-injurious thoughts and behaviors in youth, particularly potentially modifiable factors that could be targeted by interventions. One potential factor is neural reactivity to emotional stimuli. Prior research has suggested that the late positive potential (LPP), an event-related potential (ERP) component that indexes this reactivity, may be blunted in adults with a history of suicidality (i.e., ideation and/or suicidal behaviors). These findings have been interpreted in the context of cognitive models of risk, which focus on blunted reactivity to emotional stimuli broadly or to positive stimuli specifically (with perhaps heightened reactivity to negative stimuli). The goal of this study was to determine whether blunted patterns of neural reactivity toward emotional stimuli are observed in children with a history of self-injurious thoughts and behaviors (SITBs) and whether this may differ across emotional contexts (afraid, happy, sad) and intensities (low, medium, high). The study focused on 7-11-year-old children (50.51% girls, 62.63% non-Hispanic White) with (n = 16) and without (n = 83) a history of SITBs. LPP amplitudes were indexed during a Morphed Faces task, in which stimuli displaying a variety of emotional expressions (afraid, happy, and sad) were morphed to display low, medium, and high levels of each emotion. The strongest between-group difference was observed for medium-intensity positive emotional stimuli, with children with SITBs showing blunted responses. These findings provide some support for the positive attenuation hypothesis and suggest that blunted LPP response to ambiguous positive emotional stimuli may be useful as a marker of risk and potential target for intervention.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14751"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11806438/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142882931","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 this study, an emotional memory task with negative events involving the LC-NE system was combined with the short burst of event-related taVNS (3 s) in younger adults (N = 24). The aim was to investigate taVNS-induced changes in pupil dilation during encoding and possible taVNS-induced improvements in (emotional) memory performance for early and delayed (24 h) recognition. Negative events were associated with increased pupil dilation and better memory performance. Additionally, real as compared to sham or no stimulation selectively increased memory for negative events. Short bursts of stimulation, whether real or sham, led to an increase in pupil dilation and an improvement in memory performance over time, likely due to the attention-inducing sensory modulation of electrical stimulation.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 1","pages":"e14753"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11736245/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010764","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}
