This global study analyzed data from the largest dataset ever studied in Heart Rate Variability (HRV) biofeedback field, comprising 1.8 million user sessions collected users of a mobile app during 2019 and 2020. We focused on HRV Coherence, which is linked to improved emotional stability cognitive function. Positive emotions reported by were associated with higher Coherence scores more stable frequencies. In contrast, negative exhibited lower dispersed frequency distributions. The most common was identified at 0.10 Hz. However, many highest levels fell within range 0.04 Most high (standard deviation < 0.012 Hz) their coherence frequencies session session, given increased increasing Coherence. insights gained this extensive suggest that instructing breathe deeper slower find rhythm that's comfortable, they naturally unique resonant frequency. findings provide strong foundation for future research development targeted interventions aimed enhancing physiological well-being through practices.

Heart rate variability (HRV) is a widely recognized biomarker for autonomic nervous system regulation, applicable in clinical and athletic settings to monitor health recovery. Despite its extensive use, HRV measurement reliability influenced by numerous factors, necessitating controlled conditions accurate assessments. This study investigates the of short-term measurements various positions, aiming establish consistent protocols monitoring interpretation. We assessed morning 34 healthy, physically active adults across supine standing at home laboratory, over 24-hour period. Environment significantly impacted HRV. Home exhibited slightly lower variance compared lab settings, underscoring importance environment control. Our findings confirm high measurements, indicating their robustness capturing changes, provided rigorous methodology employed. Here we show that effective reliable assessment possible conditions, contingent upon strict management confounding factors. research supports utility as non-invasive diagnostic tool, emphasizing potential broadening applications diverse populations. Future studies are encouraged expand these assessments include varied demographic profiles, enhancing integration into routine evaluations.

Abstract Coordination in mothers’ and their infants’ parasympathetic nervous system functioning (i.e., respiratory sinus arrhythmia [RSA] synchrony) specifically during playful interactions may promote resilience against exposure to postpartum depressive symptoms (PPD), for both members of the dyad. To test biobehavioral synchrony theory-derived hypotheses, we evaluated whether positive mother-infant RSA play attenuated associations between maternal PPD future child behavior problems symptoms. 322 low-income, Mexican-origin mothers children participated 5-min resting baseline free interaction tasks when were 24 weeks age; reported on at 12- 36-months age. Results multilevel structural equation models demonstrated that, though differed depending levels non-interactive tasks, protective benefits 12-month 36-month internalizing specific its assessment a interaction. suggest that dyadic coordination physiological capacities is an active mechanism promotes emotional distress children.

Chronic low back pain (CLBP) after middle age is a complex multifactorial condition, and subgrouping recommended to determine effective treatment strategies. Multidimensional data help create new groupings increase the effectiveness of interventions in middle-aged older adults with CLBP. This study aimed investigate relationship between factors associated CLBP characterize subgroup based on these factors. A cross-sectional observational was conducted included 46 women aged ≥40 years who participated health events. Trunk muscle mass, lumbar movement control ability, autonomic balance, tenderness threshold, proprioception, severity central sensitization were assessed. Partial correlation analysis revealed significant negative ability balance. positive observed trunk mass threshold. Hierarchical clustering identified three subgroups. The cluster 1 participants had sensitization. 2 threshold high 3 sympathetically predominant. pressure sensitization, balance significantly different clusters. Three characteristic subgroups identified. results contribute prevention strategies for characteristics rather than uniform approach.

Psychophysiology, the flagship journal of psychophysiological research, has played a key role in field for 60 years. For present study, we conducted bibliometric analysis assessing journal's development terms performance, authorship trends, and thematic content this time span. Over years, Psychophysiology experienced consistent increase manuscript submissions, published articles, impact factor. Authorship trends showed larger, more diverse author teams, with growing percentage female first authors now representing about 50% submissions an international collaborations. Thematic evolved, shifting from peripheral measures to central nervous system like EEG ERPs while maintaining long-standing emphasis on methodological advancements. Research topics have expanded basic stimulus processing complex investigations into emotion, cognition, psychopathology, interdisciplinary integration. This article provides quantitative overview Psychophysiology's contributions development, aimed at offering insights past, current state, potential future directions research.

ABSTRACT Heart rate (HR) and heart variability (HRV) are two key measures with significant relevance in psychophysiological studies, their measurement has become more convenient due to advances wearable technology. However, photoplethysmography (PPG)‐based wearables pose critical validity concerns. In this study, we validated four PPG wearables: three consumer‐grade devices (Kyto2935, Schone Rhythm 24, HeartMath Inner Balance Bluetooth) one research‐grade device (Empatica EmbracePlus, successor the widely‐used but discontinued Empatica E4). All were worn simultaneously by 40 healthy participants who underwent conditions commonly used laboratory research (seated rest, arithmetic task, recovery, slow‐paced breathing, a neuropsychological posture manipulation standing up) encountered ambulatory‐like settings (slow walking stationary biking), compared against criterion electrocardiography device, Vrije Universiteit Ambulatory Monitoring System (VU‐AMS). We determined signal quality, linear strength through regression analysis, bias Bland–Altman error mean arctangent absolute percentage for each condition device. found that did not outperform conditions. It also showed low agreement ECG general, captured HR accurately than HRV. Finally, deviated from baseline involved slight high movement, negatively impacted between criterion. conclude devices, even those advertised designed purposes, may concerns HRV other similar resting states.

ABSTRACT Speech production interferes with the measurement of changes in cardiac vagal activity during acute stress by attenuating expected drop heart rate variability. also induces sympathetic similar to those induced psychological stress. In laboratory, confounding physiological reactivity speech may be controlled experimentally. ambulatory assessments, however, detection episodes would necessary separate effects psychosocial from speech. Using machine learning ( https://osf.io/bk9nf ), we trained and tested classification models on data 56 participants (ages 18–39) under laboratory conditions. They were equipped privacy‐secure wearables measuring thoracoabdominal respiratory inductance plethysmography (RIP a single dual‐band set‐up), thoracic impedance pneumography, an upper sternum positioned unit triaxial accelerometers gyroscopes. Following 80/20 train‐test split, nested cross‐validations run algorithms XGBoost, gradient boosting, random forest, logistic regression training set get generalized performance estimates. best model per method was then validated test set. versus no‐speech (AUC) for both cross‐validation predictions excellent thorax–abdomen RIP (nested cross‐validation: 96.6%, prediction: 98.5%), thorax‐only (97.5%, 99.1%), (97.0%, 97.8%), accelerometry (99.3%, 99.6%). The sternal accelerometer outperformed others. These open‐access leveraging biosignals have potential work daily life settings. This could enhance trustworthiness psychophysiology, enabling controlling its physiology.
