Despite decades of clinical application, evidence for its efficacy remains mixed, and the mechanisms-particularly the role of NFB learning in ADHD symptom reduction-are still not well understood. This study advances the NFB field by introducing both theoretically grounded and data-driven frameworks that conceptualize learning as a dynamic, individualized process. Data were drawn from a 25-month longitudinal randomized controlled trial of theta/beta ratio (TBR) NFB treatment in children with ADHD (N = 100; ages 7-10). Moving beyond prior work that characterized learning through binary classifications and group-level averages, we captured within- and between-session training dynamics and applied clustering methods to define distinct learner profiles, highlighting the heterogeneous nature of NFB responses. Our results demonstrate that while most participants learned to regulate TBR effectively, individual learning did not reliably predict symptom improvement. Instead, linear mixed-effects model results indicated that non-specific factors such as participant engagement and training context were more predictive of clinical outcomes. Moreover, variability in learning curve shapes-typically overlooked in standard NFB studies-suggests that NFB learning does not follow a uniform pattern, with individuals engaging through distinct mechanisms aligned with either operant-conditioning or skill-acquisition models. These insights advance theoretical understanding of NFB mechanisms and call for individualized, mechanism-informed approaches to optimize treatment outcomes and deepen clinical interpretation.</p>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147311259","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}

Over a single-session AIT, the real-time neurobiomarkers were tracked multimodally using established neurophysiological diagnostics. The study also used a 21-channel qEEG (pre-post), focused transcranial Doppler (fTCD) screening, and real-time autonomic nervous system (ANS) biosignal monitoring. Additionally, qualitative subjective outcomes of AIT were assessed for collective analysis. Findings demonstrated that both subjective emotional processing and objective biomarkers of cognitive-affective regulation had a meaningful change during and after the therapeutic intervention.

While pharmacological and psychotherapeutic interventions are available, their effectiveness remains limited, particularly for negative symptoms and cognitive impairments. These limitations, alongside drug side effects and adherence difficulties, highlight the need for new treatments. Cognitive remediation strategies like Neurofeedback show promise by harnessing neuroplasticity. This systematic review aims to evaluate the neurocognitive and humoral changes induced by Neurofeedback and its therapeutic effects in patients with schizophrenia spectrum disorders. Our review was conducted following PRISMA guidelines. Databases including EMBASE, ScienceDirect, Scopus, PsycINFO, and MEDLINE were searched for relevant studies: 14 studies, 10 RCTs, and 4 Clinical trials were selected. Inclusion criteria encompassed studies involving patients with schizophrenia spectrum disorders, Neurofeedback interventions, and outcomes related to neurocognitive and humoral changes. The Cochrane Risk-of-Bias Tool for randomized trials (RoB 2) was used to assess the quality of included studies. The reviewed studies suggest that Neurofeedback shows promise in addressing various aspects of schizophrenia spectrum disorders. Improvements were observed in processing speed, social functioning, working memory, and emotional regulation. Several studies reported successful modulation of brain activity in regions associated with auditory hallucinations. Neurofeedback training also led to increased functional connectivity between language networks and the default mode network. Some studies found improvements in brain-derived neurotrophic factor (BDNF) levels, self-efficacy, and clinical symptoms in schizophrenia patients.

Fourteen caregiving mothers (M = 49.0 ± 8.6 years) and 14 age-matched controls (M = 43.9 ± 5.8 years) participated in three five-minute conditions: resting baseline, cognitive stress, and SPB. Measures included psychological distress, resilience, body composition, musculoskeletal pain, HRV, and emotional states. Caregivers showed greater psychological distress, lower resilience, and higher visceral adiposity and musculoskeletal pain than controls. Global HRV indices (SDNN, TP) were significantly reduced in caregivers, reflecting diminished integrative autonomic capacity, whereas vagally mediated measures (RMSSD, ln(HF)) remained comparable, indicating preserved basal vagal tone despite chronic stress exposure. During SPB, SDNN, TP, ln(LF), and LF/HF increased significantly, while RMSSD and ln(HF) remained stable, suggesting a resonance-driven reorganization of autonomic activity through enhanced baroreflex-vagal coupling rather than direct vagal amplification. Emotionally, both groups showed reduced anxiety and tension following SPB; however, caregivers continued to report elevated perceived stress, indicating a psychophysiological dissociation between physiological recovery and subjective experience. These findings provide preliminary evidence that SPB facilitates short-term autonomic recovery and emotional stabilization in chronically stressed caregivers. As a rapid, low-burden, and non-pharmacological intervention, SPB holds promise for enhancing autonomic coherence and stress resilience when incorporated into caregiver support programs.</p>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146203256","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}

Twenty-four healthy adults participated in four randomized sessions (rest, deep breathing, humming breathing, and calm humming breathing) completed over five consecutive days. Humming involved a vocalized \"mm\" sound, while calm humming additionally used noise-canceling earphones for auditory occlusion. Heart rate variability (HRV) was measured, and respiration-related indices were estimated from HRV-derived respiratory sinus arrhythmia patterns. Visual analog scale (VAS) responses were collected for stress, anxiety, confidence, and relaxation. Humming and calm humming breathing produced significantly slower and more stable breathing patterns than rest and deep breathing, with respiratory frequency clustering near 0.1 Hz. Day-to-day respiratory variability was lower during humming-based breathing than during rest and deep breathing. As respiratory frequency converged toward ~ 0.1 Hz, regulated breathing conditions showed an overall pattern of increased HRV compared with rest, including higher root mean square of successive differences (RMSSD), standard deviation of normal-to-normal intervals (SDNN), total power (TP), and low-frequency (LF) power. No significant differences were observed between humming and calm humming breathing for respiratory or HRV measures. The VAS analysis revealed no significant differences across the breathing conditions. The effects of humming breathing appear to be associated with the 0.1 Hz resonance frequency induced by extended exhalation rather than the vibratory sound itself. Humming breathing, which does not require a biofeedback device, may serve as a practical alternative to cyclic breathing.</p>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146182735","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}
