In Study 1, state anxiety was induced using the Velten mood induction procedure, followed by a 2-min emotional incubation period. 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. Together, this study offers empirical support for both the Neurovisceral Integration Model and the Vagal Tank Theory.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"217 ","pages":"Article 113263"},"PeriodicalIF":2.6,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145270135","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":"2025-10-02","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}

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.

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.

We recruited 26 younger adults (aged 18–35) and 24 older adults (aged 55–89), asking them to encode and recall a list of positive, negative, and neutral words across three learning trials while their skin conductance activity was measured, and to recall the words again after 10 min.

A positive valence effect on memory specific to the encoding phase also emerged, which aligned with a significant phasic skin conductance response (SCR) to positive words. The phasic SCR while encoding positive words predicted the subsequent recall of positive words, while tonic skin conductance level, which was lower in older adults, predicted retention of negative words after the 10-minute delay. These findings suggest that physiological arousal during encoding predicts subsequent emotional memory across different ages, with phasic and tonic arousal making the greatest contributions to positive and negative memories, respectively.

Because many of these choices are defensible, a single research question can yield a range of plausible results, complicating inference, transparency, and replicability. This special issue showcases how multiverse analyses can systematically evaluate reasonable alternatives and their influence on outcomes in psychophysiology. Multiverse analyses treat datasets as one possible outcome among many, mapping how decisions shape effect estimates and subsequent inferences. This special issue illustrates multiverse thinking across four domains: (1) hypothesis and construct operationalization, including comparisons of contradictory theoretical accounts and alternative psychophysiological indices; (2) experimental design and task selection, clarifying when effects generalize across paradigms versus depend on task context; (3) data processing pipelines, highlighting which preprocessing steps impact data quality and which are comparatively benign; and (4) statistical models, testing the stability of findings across analytic specifications. Collectively, these contributions provide practical guidance for planning, executing, and transparently reporting multiverse analyses in psychophysiology. This introduction to the special issue offers a roadmap for integrating conceptual and analytic multiverses, emphasizing principled decision making, explicit justification of alternatives, and weighting evidence across analyses. Adopting a multiverse perspective from study conception through analysis can strengthen theoretical precision, identify fragile or robust effects, reconcile discrepant literatures, and improve reproducibility.
