Dysregulation within these systems is thought to contribute both to the onset and to the persistence of anxious symptoms. Among cognitive factors, worry and rumination have been identified as key vulnerabilities, as they amplify physiological arousal and disrupt autonomic regulation. Heart rate variability (HRV), a robust index of autonomic flexibility, has been consistently linked to emotion regulation, with lower HRV reflecting greater susceptibility to anxiety-related dysfunctions. The present study tested an integrative model of anxiety by examining both cognitive (worry and rumination) and physiological (HRV) markers in a non-clinical sample. Seventy-nine participants (45 female, 34 male) completed standardized self-report measures of worry and rumination and underwent a resting-state HRV assessment. We hypothesized that both cognitive and physiological indices would predict self-reported anxiety, and that their joint consideration would distinguish individuals with high versus low trait anxiety. Results supported these hypotheses: HRV and cognitive vulnerabilities independently, as well as in combination, accounted for variance in anxiety levels. These findings highlight the relevance of a psychophysiological perspective, suggesting that altered coordination between cognitive and autonomic systems may serve as an early marker of anxiety risk, with implications for detection and preventive intervention.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"218 ","pages":"Article 113286"},"PeriodicalIF":2.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145460557","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}

The Childhood Trauma Questionnaire Short Form, Delaware Bullying Victimization Scale, Negative Cognitive Processing Bias Questionnaire, and Non-Suicidal Self-Injury Questionnaire were administered to 210 junior school students (Mage = 12.92 years; 50.0 % female), who underwent a stress task (public speech task) during which data of vagal regulation indexed by respiratory sinus arrhythmia (RSA) suppression were collected. Results showed that threat experiences were positively related to non-suicidal self-injury, and negative cognitive processing bias mediated this link. Moreover, RSA suppression in response to stress served as a moderator, such that a positive association between threat experiences and negative cognitive processing bias was only evident among adolescents with higher RSA suppression but not those with lower RSA suppression. These findings suggest that negative cognitive processing bias is a potential mechanism linking threat experiences with adolescent non-suicidal self-injury, and adolescents with higher vagal suppression are more vulnerable to threat experiences and exhibit greater negative cognitive processing bias.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"218 ","pages":"Article 113287"},"PeriodicalIF":2.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145477252","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}

Research demonstrates that proactive control has neuroplasticity. The dorsolateral prefrontal cortex (DLPFC) is critically implicated in the modulation of proactive control. Theta oscillations, functioning as a neural gating mechanism, facilitate the preferential allocation of attentional resources toward the processing of memory-relevant information, thereby enhancing the maintenance of such information and playing a pivotal role in memory encoding and cognitive resource distribution. The present study employed theta-frequency transcranial alternating current stimulation (tACS) targeting the DLPFC to further elucidate the neuroplasticity of proactive control. Concurrently, to investigate the relationship between fluid intelligence and proactive control, participants' fluid intelligence was assessed pre- and post-stimulation. A cohort of 58 participants was randomly assigned to receive either left DLPFC stimulation (<em>n</em> = 29) or right DLPFC stimulation (n = 29). The results revealed that stimulation of the left DLPFC significantly enhanced participants' proactive control capabilities. In ERP indicators, the CNV, following active stimulation, the CNV in the BX condition was significantly greater than that in the pre and sham stimulation (<em>p</em> ≤ 0.006). In behavioral outcomes, the accuracy rate for the BX condition was significantly higher after active stimulation compared to that in pre-stimulation and sham stimulation (<em>p</em> ≤ 0.017). In the lDLPFC group, fluid intelligence performance was significantly enhanced, and fluid intelligence scores after active stimulation were significantly higher compared to those during pre and sham stimulation (<em>p</em> ≤ 0.032). A statistically significant correlation was observed between participants' proactive control capabilities and fluid intelligence. In the rDLPFC group, no significant changes in any of the indicators were observed. These findings underscore the efficacy of neuromodulatory interventions targeting the left DLPFC in augmenting proactive control and suggest a dynamic interplay between proactive control and fluid intelligence.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"218 ","pages":"Article 113283"},"PeriodicalIF":2.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145427152","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}

Thus, the psychophysiological measurement of MWL has been of large interest, but despite multiple decades of research, sensitivity to changes in MWL remains inconclusive (Ayres et al., 2021; Charles &amp; Nixon, 2019; Tao et al., 2019). This study therefore re-evaluates sensitivity of six psychophysiological measures to changes in MWL, namely in their ability to distinguish levels of MWL. With increasing MWL, heart rate (HR), blink rate (BR), pupil dilation (PD), skin conductance responses (SCR), and skin conductance level (SCL) were expected to increase, whereas heart rate variability (HRV) was expected to decrease. For MWL induction, an adaptation of the Swaps task (Stankov &amp; Crawford, 1993) was employed, with the aim of inducing four distinct levels of demand. MWL manipulation was successful, as in the sample of 74 university students response times significantly increased with each level, while accuracy decreased. Subjective ratings of MWL in the NASA-Task Load Index (Hart &amp; Staveland, 1988) reflected this pattern. BR and PD were highly sensitive, increasing with each level, while HR and HRV were sensitive but less able to differentiate fine-grained changes, with the inability being more pronounced for HRV. SCR were sufficiently sensitive, except for very high levels, and SCL showed no sensitivity. These findings provide further basis for research and application of psychophysiological responses to MWL, to represent task demands more comprehensively as well as mental strain in machine-operator relations.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"217 ","pages":"Article 113262"},"PeriodicalIF":2.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145228678","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}

CVA—indexed by vagally mediated heart rate variability (vmHRV), specifically high-frequency (HF) component and root mean square of successive differences (RMSSD)—was quantified from electrocardiogram (ECG) recordings during resting, anxiety induction, and recovery phases. Based on findings from Study 1, Study 2 implemented a 10-day HRV biofeedback intervention in healthy college students to evaluate its effects on tonic and phasic CVA. The protocol involves slow-paced breathing (SPB) to enhance cardiorespiratory coupling and modulate vmHRV, with real-time feedback generated from respiratory sinus arrhythmia (RSA)-related heart rate fluctuations. Results showed that CVA during anxiety was significantly higher than during both resting and recovery phases. Additionally, resting CVA was positively correlated with phasic CVA, including both reactivity and recovery. Following biofeedback training, phasic CVA—comprising reactivity and recovery—significantly increased. These findings indicate that CVA increases during emotional regulation, and higher resting CVA facilitates more adaptive vagal responses. Moreover, short-term biofeedback training appears to enhance regulatory capacity under conditions of state anxiety by modulating CVA.

Chronotype was determined using the Morningness–Eveningness Questionnaire (MEQ) and Munich Chronotype Questionnaire (MCTQ). 39 Participants (20 morning-types, 19 evening-types; aged 18–31) completed a modified monetary gambling task during EEG recording. Behaviorally, evening-types made more risky choices than morning-types, particularly after gain-correct and loss-error feedback. They also responded faster overall, with the most pronounced RT reductions after error feedback, suggesting diminished post-error slowing and greater impulsivity. Electrophysiologically, FRN amplitudes were attenuated in evening-types, especially in gain-correct and loss-error conditions. FRN amplitudes correlated with both MEQ and MCTQ scores, indicating that greater eveningness was associated with reduced neural sensitivity to outcome feedback. In contrast, no significant group differences emerged for P300 amplitudes, although both groups showed enhanced P300 responses to gain-correct outcomes, reflecting feedback salience.
