Physical activity (PA) is promising in increasing active life for older adults, but its repetitive and fatigue-inducing nature greatly harms older adults’ motivation to participate. Recently, there has been a growing interest in applying exergames to improve older adults’ PA adherence and engagement. To better support body-based interactions, embodied metaphors and multimodal feedback are suggested to ensure effective and meaningful mapping between elderly players’ input actions and exergame responses, but their effectiveness have not been fully investigated. After developing a list of embodied and ontological metaphors based a series of user-centered approaches, two experiments were conducted to investigate how embodied metaphors and multimodal feedback impact older adults'’ playing experience of PA exergames, among fifty-nine and twenty-five older adults, respectively. Regarding the embodied metaphor design, the results indicated that a higher embodiment level significantly and positively influenced the participants’ acceptance behavior in terms of their attitudes toward the exergame, and a higher information richness level demonstrated significantly positive effects on familiarity perception and all aspects of acceptance behavior. For the multimodal feedback design, the results indicated that 3D visual feedback better facilitated the participants’ sense of embodiment and immersion, as well as their acceptance behavior, compared to 2D visual feedback. Furthermore, constant tactile feedback in a continuous-only or continuous-and-augmented way significantly improved the participants’ PA movement performance and sense of embodiment, rather than instant feedback. Accordingly, a list of design guidelines for PA exergame development is proposed, with the possible contributions and limitations of this research addressed.

Traditional teaching methods have been bolstered by modern teaching methods and multimedia technology, allowing students to benefit from both new and old approaches to learning. Teaching and learning are evolving at an unprecedented rate because of the rise of online courses. Rapid advances in intelligent technologies and communication networks provide new opportunities for interactive technology innovation and technical support for hybrid teaching incorporating both on- and offline study. For this article to be helpful, it needs to examine how an intelligent mobile communication network's effective teaching combined with a hybrid teaching mode can improve the educational attainment of student teachers' English reading, among other things. This article should address these issues and more. According to this paper's findings from the experimental study, college students' desire for and capacity to learn independently in English reading courses has increased massively, and our English reading results will rise by at least 93%.

Under the background of the COVID-19 pandemic, our paper attempts to advance a dual-process model from online social support to individual resilience via diverse social capital (bonding and bridging) and political beliefs (political efficacy, political trust and city identification). Drawing on a survey of 446 residents in Shanghai, China, the findings indicate that neither informational nor emotional social support directly affects individual resilience, but indirectly influences it through different pathways. Specifically, bridging social capital mediates informational social support and individual resilience, but bonding social capital might not follow a similar path. Notably, political efficacy and political trust are involved in the above mediation between informational social support and individual resilience. Besides, the serial mediation effect of emotional social support on individual resilience via bonding social capital and then city identification or political trust is also significant. Our findings are expected to reveal the mechanism of resilience construction and prepare for the future public health crisis.

Existing literature suggests that lengthy durations of screen time (ST) are associated with lower levels of health-related quality of life (HRQoL) and other negative outcomes in children. Nonetheless, the current available evidence largely relies on cross-sectional studies. In addition, data on the content and context (parent–child co-use and solitary use) of ST are scarce. We set out to conduct a one-year, two-wave longitudinal study to investigate the association between exposure to different types of ST and HRQoL among primary school children in Hong Kong, from 2021 to 2022. A population representative random sample (N = 1428) participated in the study. Results from pooled ordinary least squares regressions showed children's ST duration was significantly associated with worse HRQoL (β = −1.101, p < 0.0001). However, interactions of ST content and context, including parent–child co-use × TV viewing (β = 1.305, p < 0.0001), parent–child co-use × video gaming (β = 0.280, p < 0.0001), solitary use × video gaming (β = 0.198, p < 0.0001), and solitary use × social media use (β = 0.454, p < 0.0001) were significantly associated with better HRQoL. Our findings suggest that increased overall durations of ST are associated with worse HRQoL in children, but this association is impacted by the types of ST content and context.

Understanding the measurement inaccuracy and bias introduced by self-reports of smartphone use is essential for making meaningful inferences about smartphone use and its effects. Evidence for the self-reports of smartphone use in intensive longitudinal studies is largely missing. Based on self-reported and digital trace data from 137 Czech adolescents (41% girls, M_age = 14.95 years), this study examined the accuracy, directional bias, and convergent validity of daily end-of-day and single-time reports of screen time and phone-checking behavior. Overall, the study found considerable discrepancies between self-reported smartphone use and digital trace and low between-person convergent validity for all self-reports considered for the study. Respondents usually reported shorter screen time and lower frequency of phone-checking behavior as compared to digital trace, both in daily and single-time self-reports. The within-person convergent validity between daily reports and digital tracking was low, indicating poor self-reports ability to capture the actual day-to-day fluctuations in smartphone use. This study adds to the existing evidence showing that self-reports based insights into how people use smartphones differ considerably from digital trace data and shows that both person and situational levels contribute to explaining the discrepancy between digital trace and self-report data among adolescents.

Social media such as Instagram have provided sexual minority youth with safer contexts to express their sexual identity authentically and positively. However, as much of the existing literature draws upon small-scale, cross-sectional, and/or qualitative designs, it is currently unclear how authentic and positive self-presentation on social media informs sexual identity development over time. This study therefore explored the longitudinal relationship between authentic and positive self-presentation on Instagram, and the sexual identity clarity and self-acceptance of sexual minority youth. The moderating effect of micro- (i.e., peer feedback on Instagram) and macro-level (i.e., cultural context) social factors was also examined. Two-wave survey data were collected from 729 sexual minority youth from the United States, the Czech Republic, and Poland (M age = 18.54, SD = 1.63, Female = 76.82%), and data were analyzed using a multi-group cross-lagged panel model. A positive reciprocal relationship was found between positive self-presentation on Instagram and self-acceptance, whilst the associations between sexual identity clarity and self-presentation were moderated by peer feedback on Instagram. Cultural context had no moderating effect on the hypothesized model. Results suggest that whilst a dynamic relationship exists between sexual identity development and self-presentation on Instagram, peer feedback on Instagram may inform the frequency and effects of potentially adaptive self-presentation. This study therefore sheds new light on the developmental and social factors that inform the social media use of sexual minority youth, and findings extend our understanding of how social media contributes to sexual identity formation.

Social pain is ubiquitous and has deleterious effects on people's health. Thus, identifying how to promote social pain recovery is important. Across three studies (N = 989), we examined whether a self-administered online awe-intervening approach could help people recover from social pain. With participants from the United States and China, we found that the online awe-intervening approach helped people recover from social pain associated with both cyber-social exclusion (Study 1) and real-life social exclusion events (Studies 2 and 3). Moreover, we found a significant mediating effect of the global sense of connectedness (Studies 2 and 3). We further demonstrated that the awe-intervening approach's effect on social pain recovery and the mediating effect of the global sense of connectedness were distinct from general positive emotions, exposure to nature, self-diminishment, and distraction (Study 3). Taken together, our findings endorse the online awe-intervening approach as an effective social pain reliever.

Problematic pornography use (PPU) is characterized by compulsive and uncontrolled pornography consumption due to a disordered reward processing system. Past studies have shown that reward involves multiple stages, but the connection between these specific stages and PPU remains unclear. In this research, an electrophysiological incentive delay task (IDT) was employed, using both erotic and monetary incentives as rewards, to decompose the distinct phases of both anticipatory and consummatory aspects of reward processing. ERP components linked to reward anticipation (cue-P3 and contingent negative variation, CNV), as well as reward feedback (reward positivity; RewP and feedback-P3; fb-P3), were investigated in a group of 31 individuals with PPU and 33 control participants. In contrast to the control group, who reacted faster to monetary cues, individuals with PPU responded more quickly to erotic cues. RT differences between erotic and monetary cues correlated with CNV amplitudes during anticipation, although no significant CNV differences across groups. In the consummatory phase, controls had higher RewP for large-monetary than large-erotic rewards, not seen in the PPU group. Conversely, the PPU group had increased fb-P3 for large-erotic over large-monetary rewards, a trend absents in controls. Our findings indicate an imbalanced sensitivity in PPU to erotic versus non-erotic rewards, evident in both the anticipatory and consummatory aspects of reward processing. This imbalance could lead to a preference for erotic rewards, possibly fostering addictive sexual behaviors.

Health misinformation has become rampant in the digital age, because people often share unauthenticated health messages on online platforms. While previous studies have pinpointed different factors that influence the dissemination of such unverified health content, few have delved into the transition from exposure to online health information to its unverified sharing. Drawing upon the theory of motivated information management, this study proposes a research model that connects online health information scanning to unverified health information sharing. Using two-wave survey data in China, we found a positive association between online health information scanning and uncertainty discrepancy in Time 1. Such discrepancy subsequently led to perceived health threat and health anxiety in Time 2, which ultimately increased unverified health information sharing in Time 2. Overall, this study enriches the information management literature by theorizing the pathways from information scanning to unverified information sharing through cognitive and emotional responses. Moreover, the findings offer practical insights for social media operators and health professionals to propose informed strategies to curb the spread of unverified health information on the internet.
