Physiological synchrony and related forms of coupling have been examined as correlates or supporting processes of such coordination. The present study investigated interpersonal breathing dynamics in nagauta-bayashi, a traditional Japanese musical ensemble characterized by long intervals between structurally defined musical events, differentiated instrumental and functional roles, and the absence of a conductor. Respiratory activity was recorded using wearable sensors from six professional performers within an 11-member ensemble during two consecutive takes of the same musical excerpt. We analyzed inter-performance and inter-performer similarities in breathing patterns, as well as event-related respiratory changes around komi, a performer-recognized coordination event used to manage temporal spacing and transitions. The results showed that breathing patterns were reproducible within individuals across takes, including players whose breathing does not directly generate instrumental sound. In terms of interpersonal breathing coordination, the data did not provide evidence for sustained lag-zero breathing synchrony over extended segments. In contrast, event-related analyses revealed a transient, ensemble-level alignment of inhalation immediately following komi events across measured performers. These findings suggest that respiratory coordination in the present nagauta-bayashi ensemble was organized as stable intra-individual respiratory patterns alongside transient, event-dependent interpersonal alignment. By demonstrating this temporally structured organization in an ecologically grounded, role-differentiated performance context characterized by sparse coordination landmarks, the study provides case-specific empirical support for dynamic accounts of joint action without presupposing sustained synchrony as the primary organizing principle.</p>","PeriodicalId":7141,"journal":{"name":"Acta Psychologica","volume":"270 ","pages":"107839"},"PeriodicalIF":3.8,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149102912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also evaluated model performance and the stability of TreeSHAP-based feature explanations across survey waves.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Data were obtained from the CHARLS. A total of 8222 participants from the 2018 wave were stratified by MCI status and randomly divided into a development set (n = 5754) and an internal validation set (n = 2468). Data from the 2020 wave (n = 5558) were used for temporal validation. LASSO regression was performed exclusively in the development set for feature selection, resulting in 27 retained predictors. Using the same feature set, seven classification models were developed: logistic regression, support vector machine, multilayer perceptron, random forest, XGBoost, LightGBM, and k-nearest neighbors. Encoding, standardization, SMOTENC resampling, and hyperparameter tuning were performed within the training folds of 10-fold cross-validation to minimize information leakage, while the original class distributions were retained in both validation sets. Model performance was assessed using the AUROC, AUPRC, classification metrics, Brier score, calibration analysis, and decision curve analysis. TreeSHAP was then applied to the prespecified XGBoost model to characterize feature contributions and assess the stability of global feature importance across survey waves.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In the 2018 internal validation set, the prespecified XGBoost model achieved an AUROC of 0.692 (95% CI: 0.660-0.724), an AUPRC of 0.282 (95% CI: 0.242-0.328), a sensitivity of 0.511, a specificity of 0.746, and a Brier score of 0.109. In the 2020 temporal validation set, the corresponding values were 0.702 for AUROC, 0.305 for AUPRC, 0.390 for sensitivity, 0.843 for specificity, and 0.137 for the Brier score. These findings indicate that discrimination remained broadly stable across survey waves, although sensitivity and calibration were limited. Decision curve analysis showed a positive net benefit for XGBoost mainly across low-to-moderate threshold probabilities. TreeSHAP analysis identified number of living children, sleep duration, educational attainment, activities of daily living (ADL), and age as the strongest contributors to model predictions. Global feature-importance rankings were highly consistent between the 2018 internal validation set and the 2020 temporal validation set (Spearman ρ = 0.996).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;This study developed an interpretable machine-learning framework for identifying current MCI status among older adults with chronic conditions.

Drawing on self-determination theory, this study investigates the forms of AI-related assessment unfairness perceived by students who reported experiencing such unfairness, and its perceived implications for students' basic psychological needs. Based on semi-structured interviews with 15 university EFL students, the findings suggest that perceived AI-related assessment unfairness takes the form of false suspicions about AI-generated coursework, unstable or opaque standards, and reward misalignment. Additionally, participants described experiences of frustration in their needs for autonomy, competence, and relatedness in relation to perceived AI-related assessment unfairness, though its perceived intensity varied with learners and contextual factors.

The survey was conducted at a cross-sectional level among university students in four major cities of Nanjing, Hangzhou, Wuhan and Xi'an, China. The collected data were analyzed by partial least squares structural equation modeling in SmartPLS 4 with 426 valid respondents. The amount of interruption salience due to the smartphone was negatively related to study effectiveness and positively related to attentional residue, while attentional residue was negatively related to study effectiveness. There was a large negative indirect relationship between smartphone interruption salience and study effectiveness via attentional residue. Self-control significantly weakened the positive association between smartphone interruption salience and attentional residue, and the significant index of moderated mediation indicated that the negative indirect association between smartphone interruption salience and study effectiveness through attentional residue became weaker at higher levels of self-control.

Sustainable supply chain practices are enacted across firm boundaries, so they depend on managers in separate firms holding compatible interpretations of environmental requirements, which places shared mental models and cognitive integration at the center of the conversion. Social network and ambidexterity theories are integrated at that cognitive level to specify three antecedents: supply chain ambidexterity (SCAX), the managerial capacity to hold refinement and search together; networking capabilities (NC), exposure to partner knowledge; and relationship learning (RL), the joint sensemaking through which exposure becomes shared understanding. Data from 334 top-level managers in Taiwanese manufacturing firms were analyzed using partial least squares structural equation modeling (PLS-SEM). RL is the strongest antecedent of SSCM (β = 0.365), ahead of NC (β = 0.276) and SCAX (β = 0.205). Where network access is widely shared, the capability that differentiates firms is not network position but the interorganizational learning that converts access into jointly held knowledge. SSCM shows its largest association with SIA (β = 0.574), the only large effect, and its smaller effect on CA is partly transmitted through SIA, which raises CA (β = 0.313). Shared cognition across firm boundaries converts relational access into sustainable practice, and SIA is the mechanism through which that practice reaches competitiveness.

The hypothesized relationships were first examined using Partial Least Squares Structural Equation Modelling (PLS-SEM), and then an Artificial Neural Network (ANN) was used to validate the findings and assess the relative significance of the predictors. The results indicate that financial socialization plays an important role in increasing financial well-being. The role of the parents and peers is an important factor of socialization, and it is crucial to highlight the importance of informal ways of financial education when formal sources of financial education are not available. The ANN analysis also further validated the results, in which the financial behavior was the most reliable predictor of the financial well-being. This study has made significant contributions to the literature in two ways: It has introduced the concept of financial socialization into the Indian context and it has demonstrated the value of combining SEM and ANN as a methodology.
