The current study investigated rhythmic stimuli perception in typically developing children (5–18 years old, n = 48, 22 girls). In the behavioral part of the study, where children discriminated between two click trains varied around frequencies of 16, 27, 40 and 83 Hz, we identified the shift toward better performance for the frequencies higher than 40 Hz. To dig into neurophysiological mechanisms of this process we recorded 28-channels EEG while similar auditory clicks were presented in trains of 500 ms with interstimulus intervals of 800–1000 ms. We focused on brain correlates of temporal and pitch-related processing — the intertrial-phase coherence at the frequency of stimulation (ITPC) and sustained wave (SW). ITPC was more pronounced under the stimulation at frequencies of 27 and 40 Hz and served as a reliable predictor of click rate discrimination at 27 Hz. Conversely, the SW exhibited a larger amplitude under the stimulation at 40 and 83 Hz and explained the variance in click rate discrimination at 40 Hz, with higher SW amplitude correlating with better performance. Our results elucidate the association of ITPC and SW with specific aspects of auditory perception in children, which might help to understand abnormalities in these responses seen in neurodevelopmental disorders.

Neural entrainment—the alignment of endogenous oscillations to the temporal structure of external stimuli—facilitates temporal prediction and enhances sensory processing. We investigated how audiovisual rhythmic stimuli at distinct frequencies modulate EEG dynamics and event-related potentials (ERPs) in 29 healthy adults. Participants observed 110 video-recorded finger-tapping sequences, categorized as low-frequency (~3.49 Hz) or high-frequency (~6.65 Hz), while 128-channel EEG was recorded. ERPs revealed larger late positive potentials for the latter than the former, with centroparietal maxima, and a right-hemisphere dominance for low-frequency rhythms. EEG spectral analyses performed within the 0.5–30 Hz range showed decreased delta power and increased alpha power during fast versus slow stimulation. Morlet wavelet analysis confirmed frequency-specific entrainment, with alpha-band increases over premotor and sensorimotor areas during high-frequency tapping. Neural entrainment analyses revealed a higher Weighted Entrainment Power Index (WEPI) for low- (3.95) compared to high-frequency stimuli (2.80), indicating stronger alignment of EEG power with slower rhythmic inputs. Consistently, the Entrainment Intensity Index (EII = 0.53 μV2/Hz) quantified a robust frequency-dependent modulation of spectral power across delta, theta, and alpha bands. Collectively, these results demonstrate selective neural entrainment to movement-sound coupling, reflected in both ERP amplitudes and EEG oscillatory power, and highlight the role of sensorimotor networks in processing temporal structure of actions.

Episodic memory refers to our ability to mentally retain personal experiences that occurred in a particular spatial and temporal context. Brain activity distinctions for spatial and temporal contexts have been observed via unicellular recordings and functional magnetic resonance imaging. However, these distinctions have not been examined using electrophysiological recordings of neural populations, such as event-related potentials (ERPs), because spatial and temporal contexts have been assessed separately. The aim was to examine electrophysiological activity distinctions between spatial and temporal contexts during encoding and retrieval. ERPs were recorded in 30 participants while they performed an associative task in which pairs of images were presented sequentially. During retrieval, participants identified whether the pair of images was spatially modified, temporally modified, identical, or new. The retrieval of spatial context was superior to that of temporal context. During the presentation of the second image of the pair, a frontal slow wave demonstrated subsequent memory effects for the correct temporal context. The FN400 was present during the recollection of the temporal context, and the parietal old/new effect was present during the recollection of the spatial context, both of which occurred when the first image of the pair was displayed. These patterns revealed that the temporal context (compared with the spatial context) required further encoding strategies and a strong distinction from familiarity at retrieval. Therefore, spatial and temporal contexts exhibit different brain activities during encoding and retrieval.

Background
Depression is a prevalent psychological disorder, and distinguishing anxious from non-anxious depression and identifying neuroimaging markers are challenges.
Method
In this study, we used public data from the REST-meta-MDD consortium, selecting 158 patients with anxious depression and 108 with non-anxious depression. We computed multiple neuroimaging metrics, including fractional amplitude of low-frequency fluctuations (fALFF), degree centrality (DC), regional homogeneity (ReHo), voxel-mirrored homotopic connectivity (VMHC), and functional connectivity (FC). We proposed the multi-scale adaptive multi-channel fusion deep graph convolutional network (MAMF-GCN) for anxious and non-anxious depression classification. This model incorporated both neuroimaging-derived features and relevant non-imaging clinical information, including site, age, gender, and Hamilton Depression Rating Scale (HAMD) scores. Furthermore, we applied the gradient backpropagation module to screen potential neuroimaging markers for depression subtyping.
Result
Our approach achieved outstanding classification results, with accuracy (ACC) of 98.12 %, sensitivity (SEN) of 99.41 %, specificity (SPE) of 97.46 %, F1-score of 98.38 %, and area under the curve (AUC) of 0.9867. Compared to state-of-the-art methods, the proposed MAMF-GCN model demonstrated superior performance. Ablation experiments confirmed that the MAMF-GCN model effectively utilizes non-imaging clinical information to significantly improve classification performance. Utilizing the gradient backpropagation module, we successfully pinpointed the top ten most discriminative features. Furthermore, we identified the cerebellar network as playing a critical role in differentiating anxious from non-anxious depression, with functional connectivity in the visual, auditory, and motor control networks serving as potential markers.
Conclusions
This method highly effective in classifying anxious and non-anxious depression and in identifying potential neuroimaging markers, thus holding significant clinical application value.

The feedback-related negativity (FRN) has been associated both with the cortical processing of reward and salience prediction errors (RPEs/SPEs), and with behavioral adjustments that optimize performance. While the FRN is sensitive to response-feedback contingencies, it remains to be explored how this waveform is influenced by random outcomes during reinforcement learning (RL) while participants develop an illusion of control (IoC). We present novel analyses of data from a previous study (Csifcsák et al., 2020), in which a group of healthy adults was intermittently exposed to compromised control over outcomes (“yoking”). Earlier, we reported effects of yoking on latent parameters of RL and oscillatory activity during decision-making, whereas now we analyzed whether the FRN was also sensitive to our controllability manipulation. Participants were randomized to “control” or “yoked” groups, differing only in their level of control over outcomes during an RL task. The FRN was analyzed both in terms of its valence-sensitivity and with respect to its association with single-trial RPEs/SPEs. Bayesian statistics confirmed comparable ratings of perceived control in the two groups, indicating IoC for yoked participants. Although response accuracy was at chance level during compromised outcome controllability, the FRN was statistically indistinguishable between the two groups, as revealed by a multitude of analytical approaches. We conclude that under IoC, the FRN is not sensitive to response-outcome contingencies, and thus, it does not reflect drops in performance. These findings suggest that the cortical analysis of outcomes is dominated by higher-order cognitive/affective states when predictions about future events are unreliable.

Mentalizing—the ability to understand and attribute mental states to others—relies on effective self-regulation and social-cognitive processing, both of which may be shaped by cardiac autonomic responses. While prior research has primarily emphasized the role of cardiac parasympathetic (PSNS) activity in social cognition, the contribution of cardiac sympathetic (SNS) activity and its dynamic interaction with PSNS remains underexplored. This study simultaneously investigated resting and task-related cardiac sympathetic-parasympathetic activity and reactivity to examine the associations with mentalizing performance in healthy young adults (N = 120). Resting heart rate variability and systolic time intervals were used to index cardiac PSNS and SNS activity, respectively, with phasic reactivity calculated as percentage change scores during mentalizing performance. Hierarchical regression analyses showed that higher cardiac PSNS activity and lower cardiac SNS activity at rest jointly predicted better mentalizing performance. Importantly, reduced cardiac SNS reactivity—but not cardiac PSNS reactivity—was a stronger predictor of mentalizing performance, and further mediated the relationship between resting cardiac autonomic activity and mentalizing performance. These findings highlighted the importance of cardiac SNS control, alongside cardiac PSNS control, in supporting socio-cognitive processing. This study suggested the understanding of efficient regulation to physiological arousal and advocated for an integrative cardiac psychophysiological model of social cognition that incorporates both cardiac sympathetic-parasympathetic branches.

Humans are inherently social beings who depend on successful social interactions. Understanding how different social stimuli elicit emotional responses is crucial for both psychological and physiological research. This study aimed to develop and validate dynamic stimulus material depicting social interactions and perspective-taking. Specifically, it examined whether emotionally charged video sequences of brief hand interactions elicit affect-specific subjective and psychophysiological response patterns.
A total of 81 healthy participants (42 female, 39 male) viewed video clips of hand interactions across four emotional contacts (Love, Neutral, Pain, and Rejection) and three perspectives (Agent, Interaction partner, and Observer). Participants rated arousal and valence using the Self-Assessment Manikin (SAM), while electrodermal activity (EDA) and heart rate (HR) were simultaneously recorded as psychophysiological indicators.
Analyses revealed significant effects of the stimuli on both subjective affect ratings and psychophysiological reactivity. SAM ratings of arousal and valence varied across emotional contacts, with perspective additionally influencing arousal. Subjective arousal was highest for Pain and Rejection, with both the Agent and Observer perspective eliciting higher arousal than the Interaction partner perspective. For subjective valence, Love was rated most positively, Pain most negatively. Similar significant effects of emotional contact, perspective, and their interactions were also observed in psychophysiological measures (EDA, HR), with Rejection inducing the highest EDA and HR. These findings demonstrate that the newly developed stimuli effectively induce distinct affective responses, providing a valuable tool for future research on affect perception and processing.

Non-suicidal self-injury (NSSI) is of increased prevalence in adolescents. Threat experiences early in life including childhood abuse and bullying victimization, are considered precursors of non-suicidal self-injury, however, the underlying mechanism remains underexplored. Therefore, the present study sought to investigate the relation between threat experiences and adolescents' non-suicidal self-injury, and the mediating role of negative cognitive processing bias and moderating role of vagal regulation in this link. 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.

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":"2025-11-07","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}

Background
An increasing body of evidence supports the use of music therapy for improving health and wellbeing. In parallel, there has also been a rising interest in the use of biomarkers to assess its impact. One such biomarker is vagally mediated heart rate variability (vmHRV), which is a non-invasive measure of cardiac parasympathetic nervous system activity. However, the influence of music therapy on vmHRV is currently unclear.
Methods
A literature search was performed in December 2023/January 2024 and updated in March 2025. Data related to vmHRV was extracted and risk of bias was evaluated. A narrative synthesis was performed according to the Synthesis Without Meta-analysis (SWiM) guidelines with an effect direction plot.
Results
Twenty-eight studies were included. There was large heterogeneity in study samples, contexts, music therapy interventions, and HRV measurement methods. There was also a high risk of bias. The results indicated increased vmHRV during music therapy. There was also an association between improved vmHRV and other positive health outcomes in these studies.
Discussion
While current evidence indicates that there are potential positive effects of music therapy on vmHRV, more high-quality research, especially regarding HRV methodology, interpretation and reporting, is needed. A high risk of bias, small sample sizes and heterogeneity in all aspects of the studies prevents any clear conclusions based on the current evidence.
