• Digitizing Dementia-Friendly Environments (DFEs): the application of digital technologies in promoting inclusive spaces (2026) · doi

  Personalized adaptive closed-loop systems that dynamically respond to patients' cognitive status and emotional changes using emotional computing and digital twin technology are only sporadically reported in the literature. Future work should develop and longitudinally evaluate personalized spatial response mechanisms that integrate real-time perception feedback with patient cognitive variability in dementia-friendly environments.

• Relational energy and coping flexibility among Chinese university students: the mediating role of optimism and the moderating influence of cognitive reappraisal (2026) · doi

  The sample is restricted to Chinese university students, limiting generalizability to other populations (working adults, adolescents, clinical groups) and cultural contexts. Future studies must test whether the strength and nature of the moderated mediation model (relational energy → optimism → coping flexibility moderated by cognitive reappraisal) differs across collectivist versus individualist cultural settings.

• Effect of Van Hiele group guided-discovery instructional approach on student engagement in learning plane geometry (2026) · doi

  The control group using traditional methods showed only minor improvements in cognitive and behavioral engagement components, but minimal data is provided on what specific traditional instructional practices were used. Future research should systematically compare VHGGDIA against multiple traditional geometry teaching approaches (direct instruction, worked examples, discovery without Van Hiele scaffolding) to isolate the contribution of the Van Hiele framework.

• A Machine Learning-Based Sentiment Analysis Framework for Twitter Tweets Using Natural Language Processing (2026) · doi

  The sentiment analysis framework is currently validated only as a standalone interactive web application; the paper identifies implementing the proposed system within actual healthcare and counseling frameworks as a critical gap requiring integration testing, clinical validation, and assessment of real-world deployment in professional mental health settings.

• Enhancing Professional Readiness Through Learner-Centered English for Specific Purposes in Business English Learning (2026) · doi

  The study proposes an ESP Experiential–Professional Model integrating experiential engagement, collaborative interaction, and cognitive–affective regulation, but does not operationalize how to diagnose or measure the triadic balance between emotional support, cognitive manageability, and professional authenticity in specific business English contexts, nor does it provide quantitative instruments for assessing this balance.

• Effects of AI-enhanced immersive learning environments on English proficiency, intercultural competence, and learner engagement (2026) · doi

  The study establishes that engagement functions as a psychological mechanism linking immersive AI-supported learning to improved performance outcomes, but does not empirically decompose the relative contributions of behavioral engagement (click count, tasks selected, dwell time) versus emotional engagement (facial expressions) in mediating language proficiency and ICC development in AI-enhanced immersive contexts.

• MOTIVATION OF HIGHER EDUCATION STUDENTS IN LEARNING MANAGEMENT SYSTEMS: FROM THEORETICAL FOUNDATIONS TO PEDAGOGICAL PRACTICE (2026) · doi

  The paper identifies that high-quality feedback in LMS requires explanation of errors and recommendations for further study, but does not empirically compare the motivational effectiveness of different feedback annotation approaches (e.g., rubric-based vs. free-form commentary) when integrated into LMS assessment tools for higher education students.

• Depression and Anxiety as Aspects of Mental Health in Celiac Disease: A Systematic Review and Meta-Analytical Synthesis (2026) · doi

  Standardized psychiatric assessment tools across celiac disease studies are lacking; future research must establish consensus on validated instruments for measuring depressive and anxiety symptoms to enable meaningful meta-analytical comparison of psychiatric outcomes.

• Multimodal approach in foreign language teaching as an alternative to the learning-styles paradigm: evidence from a survey of Moscow university teachers (2026) · doi

  Alternative science-based multimodal methods (e.g., Dual Coding Theory-based instruction, TPR, TBLT, CLIL) must be empirically tested against learning-styles practices in foreign language teaching, with measurement of both emotional comfort outcomes and cognitive learning gains. Current evidence lacks direct comparative effectiveness studies in language learning contexts.

• Living with loss: environmental grief, solastalgia, and young adults’ experiences after wildfires (2026) · doi

  A multi-cohort comparative design pairing the current urban-educated sample with rural, land-dependent populations is recommended to isolate how 'social position' specifically moderates the interaction between material loss and psychological trauma following wildfires, providing empirically robust evidence for generalizable climate adaptation strategies.

• Rhythmic skills mediate the link between music training and cognition via attention and phonological processing (2026) · doi

  The exploratory factor analysis identified phonological language processing and implicit timing as core mechanisms distinguishing high and low synchronizers, but these mechanisms have not been directly manipulated or isolated experimentally. Future studies need to employ targeted interventions—such as phonological training protocols or temporal cueing manipulations—to validate whether these factors causally mediate the rhythm-cognition relationship.

• The Effects of Deradicalization Standardized Policy in Advancing Human Security (2026) · doi

  The paper proposes a comprehensive evaluation system that measures ideological transformation through behavioral observation, attitudinal assessment, and continuous monitoring after release, but does not specify the validated psychometric instruments, assessment protocols, or threshold criteria for determining successful ideological reorientation in terrorist inmates undergoing Pancasila-based rehabilitation.

• Kindergarten Teachers' Strategies in Improving Children's Learning Concentration Performance at AT-Thayibah Kindergarten (2026) · doi

  The paper identifies that concentration in learning comprises cognitive behavior, affective behavior, psychomotor skills, and pronunciation dimensions but does not specify measurement instruments or validation criteria for assessing which behavioral indicators reliably predict improved concentration performance in kindergarten students.

• The Influence of Limited Educational Game Tools (APE) on Early Childhood Learning at RA Nurul Jihad Kindergarten (2026) · doi

  While the paper reports that the center rotation system successfully manages limited APE through small group activities, there is no empirical measurement of how rotation frequency (e.g., 15-minute vs. 30-minute rotations) and group size variability affect engagement levels and learning retention in early childhood at this specific kindergarten.

• Lived experiences of humour as a coping strategy in higher education (2026) · doi

  The mechanism by which humour performs cognitive reappraisal to reduce perceived social danger and boost self-efficacy in emotionally charged scenarios (public speaking, presentations) is theoretically proposed but not empirically tested with direct measurement of self-esteem changes or anxiety reduction in students using humour.

• Parents and community agency in early childhood education and development in rural Ghana: towards an indigenous home-based early learning model (2026) · doi

  While the study explored parental perspectives on indigenous play pedagogies, it did not measure actual child developmental outcomes; future research must employ quantitative and qualitative methods to assess the specific impacts of indigenous play pedagogies on children's cognitive, linguistic, socioemotional, and physical developmental outcomes in rural Ghana.

• Digitalizing Islamic Education: Developing a Methodological Model for Generation Z Learners (2026) · doi

  The study lacks empirical investigation of psychological effects from digital religious engagement on Gen Z identity formation, including anxiety, spiritual fragmentation, and reduced attention spans from conflicting online viewpoints. Future research should incorporate psychological frameworks and cognitive development assessments to measure how prolonged digital religious exposure affects emotional and spiritual well-being in Islamic education.

• Age differences in socio-emotional feedback processing during learning: an ERP study (2026) · doi

  The feedback stimuli were validated by younger raters (mean age 24.39 years) rather than older adults, potentially compromising stimulus validity for the older age group. Future research should validate emotional feedback stimuli separately for younger and older adults to ensure equal recognition and interpretation of happiness and disgust expressions across age groups during socio-emotional feedback processing.

• PSYCHOLOGICAL STRESS AND TRANSFORMATION OF STUDENTS' ATTITUDES TOWARDS LEARNING FOREIGN LANGUAGES IN THE CONTEXT OF THE ONGOING WAR IN UKRAINE (2026) · doi

  The study relies on 22% quantitative data on confidence increase during war and authors' personal observations of emotional state during classes, but lacks comprehensive quantitative validation across larger, more diverse student populations.

• Impact of subanesthetic ketamine delivered via AmyloLipid nanovesicle (ALN)-based intranasal system on biobehavioral responses in an animal model of PTSD (2026) · doi

  Long-term durability and safety profile of repeated intranasal ketamine administration via ALN nanovesicles have not been fully characterized in animal PTSD models.

• Mathematics Anxiety and its Impact on Academic Achievement (2026) · doi

  While the paper mentions that pedagogical approaches, collaborative learning, real-world applications, and cognitive-behavioral techniques can reduce mathematics anxiety, there is limited empirical validation of which strategies are most effective across different student populations and educational contexts.

• Health and Well-being: Indispensable in the Lives of all Individuals (2026) · doi

  No empirical validation or effectiveness metrics are provided for diary-keeping as a technique for coping with psychological problems such as anger, stress, anxiety, and depression.

• Self-Confidence and Logical Thinking as the Foundation of Academic Public Speaking for Students (2026) · doi

  Further research is expected to provide deeper understanding while serving as a basis for formulating more effective policies and learning practices in higher education.

• The impact of the mathematical adversity quotient on preparatory students’ mathematics learning engagement: moderated mediation effect analysis (2026) · doi

  Caution is warranted in generalizing the magnitude of effects to other student populations beyond the preparatory context, though underlying theoretical pathways may retain broader relevance.

• Digital mindfulness, trait anxiety, and psychological wellbeing: the chain mediating roles of emotion regulation and self-compassion (2026) · doi

  Individual differences, such as dispositional mindfulness, may have influenced both engagement in digital mindfulness practices and the observed psychological outcomes. Longitudinal or experimental designs incorporating trait mindfulness measures would help clarify these alternative explanations.

• Beyond cognition: the four-seasons framework for integrating affect into mathematics teaching (2026) · doi

  The framework's effectiveness needs to be tested across diverse cultural, linguistic, and socioeconomic contexts beyond Taiwan to establish broader generalizability.
