We design and implement an innovative framework based on a Hierarchical Deep Q-Network (HDQN) that effectively processes and learns the inherent multi-scale and multi-granularity characteristics of physical fitness data. The introduction of a hierarchical structure enables the model to capture subtle patterns at different levels of abstraction, from low-level sensor fluctuations to high-level behavioral patterns. The Deep Q-Network component trains an agent that learns an optimal policy for identifying nuanced and complex anomalous data points or sequences, moving beyond traditional threshold-based methods. Evaluated on a real-world dataset comprising 300 participants monitored over 60 days with 8-dimensional physiological metrics, our HDQN framework achieved superior performance with an F1-score of 0.811, outperforming traditional machine learning methods (Isolation Forest: 0.611, One-Class SVM: 0.575), deep learning approaches (LSTM Autoencoder: 0.703), and non-hierarchical Deep Q-Networks (Flat-DQN: 0.743). The hierarchical architecture inherently supports interpretation of detected anomalies by localizing contributory factors within specific data dimensions or temporal segments. Robustness analysis demonstrated that HDQN maintained stable performance with only 3.82% F1-score degradation under 10% Gaussian noise, significantly better than baseline methods. This amalgamation of hierarchical representation learning and deep reinforcement learning significantly enhances the precision of anomaly detection, provides meaningful explanations for identified deviations, and offers a more comprehensive understanding of an individual's dynamic health status, paving the way for proactive and personalized health interventions in physical education and sports science contexts.</div></div>","PeriodicalId":47673,"journal":{"name":"International Journal of Clinical and Health Psychology","volume":"26 2","pages":"Article 100706"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13314886/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148364536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transcranial pulse stimulation (TPS), a focused ultrasound-based neuromodulation technique, has shown preliminary promise in improving neuropsychiatric symptoms, but its effects on sustained attention in young adults are unclear.

This study examines the impact of exercise-based VR with varying cognitive demands on physical activity enjoyment and acute cardiovascular responses in young adults, with a particular focus on individual differences in habitual physical activity. College students (ages 18–25) were randomly assigned to one of two 60-minute VR exercise conditions: Low Load (<em>n</em> = 25) or High Load (<em>n</em> = 25). To preserve ecological validity, participants engaged with experimentally modified versions of a commercially available VR exergame for acute aerobic training. Key outcomes included self-reported enjoyment of physical activity, frequency of physical activity, and engagement in heart rate zones. Results showed that participants in the High Load condition experienced greater increases in enjoyment from pre- to post-exercise compared to those in the Low Load condition. Notably, sedentary individuals in the High Load group reported the greatest increases in physical activity enjoyment, suggesting that cognitive engagement may enhance exercise appeal for less active populations. All participants, regardless of condition, reached target cardiovascular intensity zones. These findings highlight the potential of cognitively demanding VR to promote physical activity engagement among sedentary young adults. By integrating cognitive stimulation into immersive exercise environments, VR technologies may serve as scalable, accessible tools for behavioral change.

Interpersonal synchrony is a core mechanism associated with therapeutic alliance and treatment outcomes in psychotherapy. However, given the largely correlational nature of current literature, manipulation of synchrony is essential in order to reveal its potential causal relationships with therapeutic relationships in psychotherapy. Despite growing recognition of its clinical significance, synchrony remains difficult to manipulate because it often emerges implicitly, shaped by relatively stable individual and interpersonal characteristics. This paper first introduces an Extended Reality (XR)-based framework for understanding interpersonal synchrony, drawing from Milgram and Kishino’s Reality–Virtuality continuum. We then use this framework to map options for synchrony manipulation during therapeutic encounters involving real and digital entities. We then explore the different challenges of implementing these synchrony manipulations, including conceptual, technological, and ethical issues. This outlines a future-oriented perspective on the potential of XR to provide an infrastructure for synchrony manipulation. This may provide new opportunities for tailoring therapy to individual synchrony profiles, with potential applications in treating disorders marked by interpersonal dysfunction, such as social anxiety or autism spectrum disorder. Ultimately, XR manipulation of synchrony may transform both research and clinical practice by bridging the gap between static trait-like tendencies and the facilitation of adaptive therapeutic flexibility.</div></div>","PeriodicalId":47673,"journal":{"name":"International Journal of Clinical and Health Psychology","volume":"26 2","pages":"Article 100688"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147806067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
