VR rehabilitation is a rapidly evolving field, with increasing research and development aimed at improving its effectiveness, accessibility, and integration into mainstream healthcare systems. While there are some commercially available VR rehabilitation programs, their adoption and use in clinical practice are still limited. One of the limitations is defined as cybersickness, which is dependent on human contact with virtual reality products. The purpose of this essay is to raise awareness of the associated elements that contribute to cybersickness in rehabilitation using immersive VR. The common factors that influence the amount of cybersickness are user characteristics and device software and hardware. The Simulator Sickness Questionnaire (SSQ) was used as one of the formal models for determining the variables related to virtual reality sickness. The systematic review of the literature and the meta-analysis were chosen by whether the Simulator Sickness Questionnaire in the articles matched the research criteria. Based on PRISMA guidelines, a systematic review of the literature was conducted. Twenty-six publications from the recent past were totaled, comprising 862 individuals with ages ranging from 19 to 95, and 49% were female. The highest overall SSQ mean score for different kinds of symptoms was determined to be 21.058 for brain injuries, with a 95% confidence interval (CI) of 15.357 to 26.760. Time, content, locomotion, control, and display types were other elements that contributed to cybersickness and had significant p-values in the SNK Q-test. The future direction of immersive VR rehabilitation involves the development of immersive and interactive environments that simulate real-world situations, providing patients with a safe and controlled environment in which to practice new skills and movements.

Brain regions associated with creativity is a focal point in research related to the field of cognitive neuroscience. Previous studies have paid more attention to the role of activation of the left dorsolateral prefrontal cortex in creativity tasks, which are mostly abstract conceptual tasks, and less attention to real-world creativity tasks. The right dorsolateral prefrontal cortex is involved in functions such as visuospatial processing, which may have a positive impact on innovative solutions to real-world problems. In this study, tDCS technology was used to explore the effect of anodal stimulation of the right dorsolateral prefrontal cortex on design creativity performance in a real-word problem-solving task related to product design. The experimental task comprised three stages, of which the first two were idea generation stages based on divergent thinking using text and graphics, respectively, whereas the third was the creative evaluation stage based on convergent thinking. Thirty-six design students were recruited to partake in the experiment. They were randomly assigned into anodal stimulation and sham stimulation groups. The results showed that anodal stimulation of the right dorsolateral prefrontal cortex produced a significant positive effect during the creative evaluation stage, promoting the usefulness of ideas (p = 0.009); thus, improving product creativity scores. However, there was no significant impact on the idea generation stage (p > 0.05), which is dominated by divergent thinking. The results suggest that activating the right dorsolateral prefrontal cortex with tDCS can improve people’s performance in creative activities by promoting convergent thinking rather than divergent thinking. It also provides further evidence that the right hemisphere of the brain has an advantage in solving complex problems that require the participation of visuospatial information.

Background: Although smart products improve older adults’ quality of life, their acceptance and usage of smart assistive devices remain relatively low, and the influencing factors remain unclear. Methods: This study takes canes, which are commonly used by older adults, as the research object. To explore older adults’ acceptance of smart canes and the influencing factors, we constructed an integrated framework based on the extended Technology Acceptance Model (TAM), which incorporates multiple variables: Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Attitude (ATT), Social Influence (SI), Safety Trust (ST), Self-Efficacy (SE), and Behavioral Intention (BI). A questionnaire survey was conducted to collect 232 valid responses, and structural equation modeling (SEM) was employed for data analysis. Results: The results indicate that factors including PU, PEOU, and SI have significant impacts on older adults’ ATT towards using smart canes, their SE, and BI. Among these factors, ATT and SE play a mediating role between PU, PEOU, SI, and BI in using smart canes. Conclusions: The practical implications of the current results are discussed with the aim of providing empirical evidence for the development and application of smart assistive devices for older adults.

Anthropomorphism is a widely used marketing strategy, yet less is known about how baby-schema anthropomorphic cues embedded in eco-friendly logos function as compact visual identity cues to promote consumers’ green purchase intention through positive emotional attribution. Drawing on baby-schema theory and mental-state attribution, we examine the impact of anthropomorphic eco-friendly logos on green purchase intention, the mediating roles of perceived love and perceived hope, their sequential pathway, and the moderating effect of environmental attitude. A within-subjects study was conducted with 299 valid participants in China, using established and adapted scale items for data collection. Our results demonstrated that anthropomorphic eco-friendly logos significantly enhanced green purchase intention. Perceived love and perceived hope each mediated this relationship, and the sequential pathway from perceived love to perceived hope was also significant. Moreover, environmental attitude positively moderated the link between anthropomorphic logos and perceived love, with a stronger effect among consumers with higher pro-environmental attitudes. These findings highlight a positive emotional attribution mechanism through which anthropomorphic eco-friendly logo cues promote green consumption and clarify the boundary role of environmental attitude.

Ugly–cute memes, which blend visual incongruity with cuteness, have become a prominent form of nonconventional online esthetics on social media, yet little is known about who prefers them and why. The present research examined how perfectionistic discrepancy and stress-related states relate to ugly–cute meme preference across two studies. In Study 1, 356 Chinese adults completed the Discrepancy subscale of the Almost Perfect Scale–Revised, together with measures of perceived stress, state anxiety, and preference for a pretested ugly–cute meme. The mediation model yielded a negative direct association between perfectionistic discrepancy and ugly–cute meme preference, as well as positive indirect associations through state anxiety and through the serial path from perceived stress to state anxiety. Study 2 used a randomized recall-based stress induction with 393 valid participants. Compared with participants in the neutral-recall control condition, those in the stress-recall condition reported higher state anxiety, rated ugly–cute images more favorably, and were more likely to choose an ugly–cute image in the forced-choice task. The estimated indirect effect of the stress manipulation on ugly–cute image preference through state anxiety was statistically significant. Overall, stress-related states appear to increase the appeal of ugly–cute content. Perfectionistic discrepancy, in turn, relates to this preference through opposing direct and indirect routes.
