Vocal production requires the coordinated control of respiratory, laryngeal, and autonomic systems. In individuals with high vocal demand, this physiological load may influence autonomic regulation, even in the absence of voice disorders. This scoping review systematically mapped current evidence on the relationship between voice production and autonomic nervous system (ANS) activity in adults, focusing exclusively on studies that assessed both systems simultaneously. A systematic search was conducted in PubMed, Scopus, Web of Science, Embase, and CINAHL, following PRISMA-ScR guidelines. Eligible studies included adults performing structured vocal tasks with concurrent autonomic measurements. Data were extracted and synthesized descriptively. Fifteen studies met the inclusion criteria. Most involved healthy adults with high vocal demand, while some included participants with subclinical or functional voice traits. Vocal tasks ranged from singing and sustained phonation to speech under cognitive or emotional load. Autonomic measures included heart rate (HR), heart rate variability (HRV), and electrodermal activity (EDA), among others. Four thematic trends emerged: autonomic synchronization during group vocalization; modulation of autonomic tone by vocal rhythm and structure; voice–ANS interplay under stress; and physiological coupling in hyperfunctional vocal behaviours. This review’s findings suggest that vocal activity can modulate autonomic function, supporting the potential integration of autonomic markers into experimental and clinical voice research.

The development of social media has brought new challenges to government risk communication, and the public has put forward higher requirements for emotionality, novelty, and interactivity in communicating risk information. Based on this, the Chinese emergency government has adopted a new expression on social media platforms—cute discourse. The emergency government’s use of cute discourse to mitigate negative public emotions and enhance information attraction. Although there is a large number of studies on government risk communication on social media, there is a lack of research on the effectiveness of using this new expression. In this study, we analyzed the 11,152 emergency government’s posts on Weibo in China and assessed the impact of the use of cute discourse on risk communication effect under a mixed research method. The results show that within the range of sample values, the use and degree of the emergency government’s cute discourse improves communication effectiveness. Additionally, the driving effect of the use and degree of the emergency government’s cute discourse on risk communication varied across crisis types, risk stages, and risk themes. These results provide novel approaches and new perspectives for the study of governmental risk communication discourse. Full article

Many common chemicals are known or suspected to harm brain development, and children are particularly vulnerable, yet research on their long-term effects on mental health is limited. This study investigated the associations of early childhood exposure to endocrine disrupting and neurotoxic chemicals with the development of internalizing, externalizing, and attention-deficit/hyperactivity disorder (ADHD) symptoms from early childhood through adolescence in 387 children from the Rhea cohort in Crete, Greece. At age 4, serum concentrations of 3 organochlorine pesticides and 14 polychlorinated biphenyls, and urinary concentrations of 7 phthalate metabolites and 6 dialkyl phosphate metabolites were measured. Children’s symptoms were assessed via maternal reports at ages 4, 6, 11 and 15 years. Using generalized estimating equation models, the study found that early exposure to hexachlorobenzene (HCB) and dichlorodiphenyldichloroethylene (DDE) was associated with increased externalizing symptoms across ages in girls [beta (95% CI): 0.20 (0.04, 0.37) and 0.11 (0.01, 0.21), respectively]. Among girls, low molecular weight (LMW) phthalates were also linked to elevated internalizing and externalizing symptoms, as well as ADHD-related difficulties [beta (95% CI): 0.15 (0.04, 0.26), 0.13 (0.01, 0.25), and 0.13 (0.02, 0.24), respectively]. Additionally, exposure to organophosphate pesticides was associated with increased externalizing and ADHD symptoms [beta (95% CI): 0.13 (0.04, 0.22) and 0.12 (0.04, 0.20), respectively]. The findings suggest that early childhood exposure to environmental chemicals may have long-term effects on emotional and behavioral development, with pronounced effects observed only in girls.

This article examines online hate as a driver of cyberbullying and a barrier to inclusive schooling, integrating theoretical, philosophical and methodological perspectives. We approach hate speech as communicative practices that legitimise discrimination and exclusion and, once amplified by social media affordances, erode equity, belonging and well-being in educational settings. The study adopts a qualitative, exploratory–descriptive design using focus groups with pre-service teachers from initial teacher education programmes across several Chilean regions. Participants reflected on the presence, trajectories and classroom effects of cyberhate/cyberbullying. Data were analysed thematically with ATLAS.ti24. Findings describe a recurrent pathway in which anonymous posts lead to public exposure, followed by heightened anxiety and eventual withdrawal. This shows how online aggression spills into classrooms, normalises everyday disparagement and fuels self-censorship, especially among minoritised students. The analysis also highlights the amplifying role of educator authority (tone, feedback, modelling) and institutional inaction. In response, participants identified protective practices: explicit dialogic norms, rapid and caring classroom interventions, restorative and care-centred feedback, partnership with families and peers, and critical digital citizenship that links platform literacy with ethical reasoning. The article contributes evidence to inform anti-bullying policy, inclusive curriculums and teacher education by proposing actionable, context-sensitive strategies that strengthen equity, dignity and belonging.

Physical activity integration in elementary education seeks to promote academic performance and the physical, emotional and social health of students. This study aims to examine the effect of active methodologies involving physical activity in primary school students through a detailed review of the scientific literature. A systematic review was conducted regarding PRISMA guidelines. Searches were performed in Web of Science, Scopus and SPORTDiscus. Studies published between 2018 and April 2024 were selected. The studies focused on the application of active methodologies in primary school populations. The quality of the studies was assessed using the Standard Quality Assessment Criteria for Evaluating Primary Research Articles from Various Fields. After screening and review, 22 articles were included. Most of the studies had longitudinal quasi-experimental or repeated measures designs with a randomized cluster-controlled pilot trial. Cross-sectional studies with descriptive data and mixed methods were also included. Cooperative learning and active breaks were found to improve engagement, classroom behavior, and academic outcomes. In addition, gamification and challenge-based learning also showed positive effects on motivation and engagement, although these were more context-dependent. Shorter or small-scale interventions produced promising but less robust results. Active methodologies improve primary education outcomes, but inconsistent designs limit generalization. Full article

Background: This study examined changes in psychological adjustment among patients with Anorexia Nervosa (AN) and Binge Eating Disorder (BED) following a 3-week inpatient multidisciplinary (disease-tailored) rehabilitation program. Methods: twenty consecutive Italian female adults with a diagnosis of AN (mean age ± SD: 25.9 ± 9.4 years; mean Body Mass Index: BMI: kg/m²: 15.8 ± 1.61) and fifteen consecutive Italian female adults with diagnosis of BED (mean age ± SD: 43.5 ± 15.3 years; mean Body Mass Index: BMI: kg/m²: 41.1 ± 7.82) were admitted to the study. Psychological functioning and well-being were assessed pre- and post-intervention using the Strengths and Difficulties Questionnaire and the Psychological General Well-Being Index. Results: Significant improvements in emotional symptoms [F(1, 31) = 21.1973, p < 0.001, ƞ²p = 0.406] and overall psychological functioning [F(1, 31) = 10.0062, p = 0.373, ƞ²p = 0.026] were observed in both groups, with the most pronounced changes in internalizing symptoms, such as anxiety and depression. Changes in BMI were significantly associated with emotional symptoms, vitality [F(1, 31) = 4.89, p = 0.035, ƞ²p = 0.136], and total well-being scores [F(1, 31) = 6.341, p = 0.017, ƞ²p = 0.170]. By contrast, no significant changes were observed in domains such as behavioral problems, hyperactivity/inattention, and peer relationships, probably indicating the need for more prolonged and targeted, domain-specific interventions. Conclusions: A 3-week inpatient multidisciplinary program was associated with improvements in internalizing symptoms and psychological well-being in women with AN and BED. Domains such as behavioral regulation and social functioning showed limited change, indicating the need for longer and targeted psychosocial components. Full article

Online customer reviews contain rich sentimental expressions of customer preferences on products, which is valuable information for analyzing customer preferences in product design. The adaptive neuro fuzzy inference system (ANFIS) was applied to the establishment of customer preference models based on online reviews, which can address the fuzziness of customers’ emotional responses in comments and the nonlinearity of modeling. However, due to the black box problem in ANFIS, the nonlinearity of the modeling cannot be shown explicitly. To solve the above problems, a chaos-driven ANFIS approach is proposed to develop customer preference models using online comments. The model’s nonlinear relationships are represented transparently through the fuzzy rules obtained, which provide human-readable equations. In the proposed approach, online reviews are analyzed using sentiment analysis to extract the information that will be used as the data sets for modeling. After that, the chaos optimization algorithm (COA) is applied to determine the polynomial structure of the fuzzy rules in ANFIS to model the customer preferences. Using laptop products as a case study, several approaches are evaluated for validation, including fuzzy regression, fuzzy least-squares regression, ANFIS, ANFIS with subtractive cluster, and ANFIS with K-means. Compared to the other five approaches, the values of mean relative error, variance of error, and confidence interval of validation error are improved based on the proposed approach. Full article

Background/Objectives: Infant emotional responses during complementary feeding offer key insights into early developmental processes and feeding behaviors. AI-driven facial emotion analysis presents a novel, objective method to quantify these subtle expressions, potentially informing interventions in early childhood nutrition. We aimed to investigate how maternal and infant traits influence infants’ emotional responses during complementary feeding using an automated facial analysis tool. Methods: This multi-center study involved 117 typically developing infants (6–11 months) and their mothers. Standardized feeding sessions were recorded, and OpenFace software quantified six emotions (surprise, sadness, fear, happiness, anger, disgust). Data were normalized and analyzed via Generalized Estimating Equations to identify associations with maternal BMI, education, work status, and infant age, sex, and complementary feeding initiation. Results: Emotional responses did not differ significantly across five food groups. Infants of mothers with BMI > 30 kg/m² showed greater surprise, while those whose mothers were well-educated and not working displayed more happiness. Older infants and those introduced to complementary feeding before six months exhibited higher levels of anger. Parental or infant food selectivity did not significantly affect responses. Conclusions: The findings indicate that maternal and infant demographic factors exert a more pronounced influence on infant emotional responses during complementary feeding than the type of food provided. These results highlight the importance of integrating broader psychosocial variables into early feeding practices and underscore the potential utility of AI-driven facial emotion analysis in advancing research on infant development.

Once an online public opinion emerges, the interweaving of information distortion and public panic makes it difficult for enterprises to accurately grasp the emotional turning point and formulate sustainable marketing strategies. Based on the perspective of information asymmetry, in this paper, we construct a four-agent evolutionary game model involving the central government, local governments, enterprises and netizens. It analyzes the balance of strategies used by different actors in public opinion crises and examines how these strategies drive public panic from three perspectives: content, users and emotions. Finally, the findings are verified through simulation calculations. Our research reveals that when panic sentiment is in the medium range, the central government’s strengthened supervision coexists with enterprises’ deceptive marketing, and the impact of the event is magnified. When panic breaks through the threshold, local governments shift from full disclosure to partial disclosure, while consumers maintain their purchasing confidence and are less likely to be swayed by rumors. Research shows that after a public opinion crisis occurs, only by replacing deception with transparent and genuine content and jointly creating green solutions with consumers can enterprises transform panic into sustainable brand assets and provide a decision-making basis for the long-term development of the enterprise.

This article explores how natural wood materials—especially untreated or minimally treated timber—are perceived and experienced during tourist experiences in recreational and tourism-oriented built environments. Drawing on principles of biophilic design and cultural theories of authenticity, the study examines both the psychological and the physiological impacts of wood surfaces on users. One of the objectives of this study is to strengthen the theoretical background and to explore the connections between tourists’ experiences and the material environment. Two pilot studies were conducted: a questionnaire administered to visitors of a national design fair (n = 37) and a physiological experiment measuring user responses to three material types (solid oak, chipboard, and white laminate). The results indicate that natural wood evokes significantly more positive emotional responses and is strongly associated with authenticity, sustainability, and comfort, although concerns about hygiene and surface aging persist. A SWOT analysis is used to summarize the strategic opportunities and risks associated with wood in tourism design. The findings support the inclusion of natural wood as a multisensory design element that enhances atmosphere, emotional engagement, and perceived environmental quality—especially when surface maintenance and cultural framing are appropriately addressed.

The interaction between microorganisms in the dental microfilm (plaque) at the gingival margin, the immune system, and the brain is vital for gingival health. The brain constantly receives information regarding microbial composition and inflammation status through afferent nerves and the bloodstream. It modulates immune responses via efferent nerves and hormonal systems to maintain homeostasis. This relationship determines whether the gingiva remains healthy or develops into gingivitis (non-destructive inflammation) or periodontitis (a destructive condition), collectively referred to as periodontal disease. Factors associated with severe periodontitis heighten the responsiveness of this homeostatic system, diminishing the adaptive immune system’s defence against symbiotic microorganisms with pathogenic properties, known as pathobionts. This leads to excessive innate immune system activation, effectively preventing infection but damaging the periodontium. Consequently, investigating the microbiota–brain axis is vital for understanding its impact on periodontal health and disease. Herein, we examine recent advancements in how the defence against pathobionts is organised within the brain, and how it regulates and adapts the pro-inflammatory and anti-inflammatory immune balance, controlling microbiota composition. It also discussed how pathobionts and emotional stress can trigger neurodegenerative diseases, and how inadequate coping strategies for managing daily stress and shift work can disrupt brain circuits linked to immune regulation, weakening the adaptive immune response against pathobionts.

This study investigates the viability of using ChatGPT 3.5 to produce smoking cessation messages featuring different emotional appeals. The effect of source attribution to Artificial Intelligence (AI) vs. human experts is also examined. A sample of current smokers (N = 480) was recruited from Prolific and randomly assigned to read one of five ChatGPT-generated messages reflecting a 2 (appeal: threat vs. humor) × 2 (source: AI vs. human experts) factorial design plus an irrelevant message control condition. Exposure to the smoking cessation messages led to a pattern of cognitive and emotional responses largely consistent with expectations based on previous research. Compared to control, the smoking cessation messages generated greater risk perceptions on the featured health effects but did not produce significantly stronger intentions to quit. Human experts as the source produced greater perceived source credibility than AI, but there was no source effect on other outcomes. No interaction between message appeals and source attribution was observed. Implications of the findings for tobacco education campaigns are discussed. Full article

Background/Objectives: This study aimed to linguistically and culturally adapt the Social Participation Restrictions Questionnaire (SPaRQ) and the Hearing Handicap Inventory (HHI) for the Elderly/Adults to Danish and to investigate the reliability and validity of the questionnaires and their subscales in a clinical population. These questionnaires are quantifiable self-assessment tools that are used internationally to evaluate the social–emotional impacts of hearing impairment. Methods: The translation and cross-cultural adaptation procedures followed recommendations to adapt hearing-related questionnaires for different languages and cultures. In total, 64 participants (43 hearing aid users and 21 hearing aid candidates) completed both questionnaires using a test–retest paradigm. Results: Reliability analysis showed good internal consistency (Cronbach’s alpha between 0.82 and 0.94) and good agreement between the test and retest rounds (intraclass correlation values between 0.79 and 0.88) with both questionnaires. Neither SPaRQ nor HHI were correlated with better-ear PTA. However, SPaRQ and HHI, as well as their subscales, were significantly correlated with each other. Significant differences were observed at baseline between the HA users and candidates in terms of the better-ear PTA, but the distributions of subscale scores were broad and overlapping. Conclusions: The Danish version of SPaRQ is a reliable instrument for measuring the subjective impacts of hearing impairment. It can be used to capture the experiential aspects of hearing impairment that are not necessarily captured with objective measures of hearing. Full article

Purpose: This study aimed to evaluate retrospectively self-reported changes in tinnitus severity and distress associated with the COVID-19 pandemic and vaccination using validated self-report instruments. It further explored patient-reported onset of tinnitus following vaccination, gender differences in symptom severity, and associations with psychological distress. Method: A cross-sectional online survey was completed by 189 adults between December 2023 and April 2024. Participants retrospectively self-reported tinnitus onset and severity before, during, and after the COVID-19 pandemic using the Tinnitus Handicap Inventory (THI) and the Tinnitus Reaction Questionnaire (TRQ). Additional items assessed COVID-19 vaccination history, infection status, and adverse vaccine reactions. Repeated measures ANOVAs and chi-square tests were used to examine retrospectively reported longitudinal changes and group differences. Results: Mean THI scores increased significantly over time—before (M = 9.57, SD = 16.00), during (M = 29.97, SD = 32.30), and currently (M = 36.92, SD = 28.04)—with large effect sizes across functional, emotional, and catastrophic subscales (p < 0.001). TRQ scores also were reported to rise from before (M = 7.86, SD = 15.29) to during (M = 26.38, SD = 29.58) and remained elevated at the current time (M = 29.79, SD = 24.00), p < 0.001. Approximately 25.9% and 27.0% of respondents reported new or worsened tinnitus after the first and second vaccine doses, respectively. No significant gender differences in symptom severity were observed. TRQ severity classification revealed a marked shift, with moderate or greater distress increasing from 5.8% (before) to 35.6% (current). Conclusions: Retrospective self-reports indicated that tinnitus burden significantly increased during the COVID-19 pandemic and remained elevated at the time of survey completion. A notable proportion of individuals reported new-onset tinnitus following vaccination, though causality cannot be inferred. These findings highlight the need for continued monitoring and comprehensive care addressing both audiological and psychological components of tinnitus. Full article

Rapid socio-spatial change in China’s traditional villages threatens living heritage and weakens locally grounded identity. This paper theorizes place identity as a dynamic, embodied and performative ecology and examines it in Dali Dong Village across four dimensions, emotional attachment, symbolic meaning, continuity and behavioural commitment, using a triangulated qualitative design that integrates interviews, spatial observation and visual ethnography. Findings show that identity is enacted around ritual architectures and everyday settings, particularly the Drum Tower, Flower Bridge, and Sa altar. Emotional attachment and symbolic meaning are expressed consistently across sources, whereas continuity and behavioural commitment are uneven, shaped by ritual fatigue (compressed rehearsal windows), symbolic commodification under tourism, and selective continuity in intergenerational transmission. These mechanisms identify where the identity fabric is most fragile and where intervention leverage lies. Conceptually, the study relocates place identity from cognition-centred, urban models to ritualized rural lifeworlds. Practically, it offers a portable framework for community-anchored stewardship that can be adapted to similar settlements and aligned with policy aims for safeguarding living heritage. Full article
